How should a business compare integrated payroll within accounting software vs using a separate payroll provider?

The key is to compare total operating cost, control, integration, and payroll complexity—not just the monthly software fee.

At a glance

Integrated systems can reduce duplicate data entry and improve labor-cost visibility, while separate providers can offer more specialized payroll and HR capabilities.

The most important comparison criteria

1. Measure the total cost, not the subscription price

For each option, calculate:

Software fees + payroll fees + implementation + accounting reconciliation + internal staff time + error/compliance costs

For example, a separate provider that costs $300 more per month might actually be cheaper if it saves your bookkeeper 10 hours per month.

Also look for charges for:

• Additional employees
• Multiple states
• Year-end W-2/1099 processing
• Tax filings
• Amendments
• Direct deposit
• Time tracking
• Benefits administration
• Workers' compensation
• HR support
• Integrations

2. Evaluate how complicated your payroll really is

Integrated payroll is usually attractive when you have:

• A relatively small employee base
• One or a few locations
• Straightforward hourly/salary compensation
• Limited benefits complexity
• One primary accounting system
• A finance/bookkeeping team that already lives in that system

A separate provider becomes more attractive when you have:

• Employees in multiple states
• Multiple legal entities
• Complex commissions, bonuses, tips, or overtime
• Significant benefits administration
• 401(k) and other deductions
• Sophisticated timekeeping
• Rapid employee growth
• A need for dedicated payroll/HR expertise

3. Don't underestimate integration quality

"Integrates with accounting" can mean very different things.

Ask whether the payroll system can automatically send:

• Gross wages
• Employer payroll taxes
• Employee tax withholdings
• Benefits deductions
• Retirement contributions
• Department/location/job labor costs
• PTO accruals
• Payroll liabilities
• Journal entries

Ideally, payroll should produce a clean, automated accounting entry rather than requiring your bookkeeper to download a report and manually reconstruct payroll.

4. Compare compliance responsibilities carefully

This is particularly important. Outsourcing payroll doesn't necessarily transfer the legal responsibility away from the employer. The IRS says employers generally remain responsible for employment taxes even when a third-party payroll provider handles filings and payments; if a provider fails to make required deposits, the employer can still face taxes, penalties, and interest.

So don't simply ask, "Does the provider handle payroll taxes?"

Ask:

• Who calculates the taxes?
• Who files each federal and state return?
• Who makes deposits?
• Who handles notices?
• Who corrects errors?
• What liability does the provider assume?
• How can we independently verify tax payments?
• What happens if the provider makes a mistake?

The IRS specifically recommends that employers use EFTPS to verify federal tax deposits made by a third-party provider.

5. Consider the accounting team's workflow

This is where integrated payroll often wins.

Suppose payroll is $100,000 for the month. With a well-integrated system, the accounting team might simply review and approve a generated payroll journal entry.

With a separate system, you may have:

Payroll system → export → accounting system → reconciliation → corrections

That's not necessarily bad—but the more frequently data has to be moved or reconciled manually, the greater the opportunity for errors.

A practical decision rule

I'd use this framework:

Choose integrated payroll if:

"Our payroll is relatively straightforward, and our biggest priority is keeping payroll and accounting simple and tightly connected." Choose a separate payroll provider if:

"Payroll is becoming its own operational function, and we need deeper payroll/HR expertise, compliance support, or flexibility than our accounting system provides." There's also a hybrid possibility worth considering: keep your accounting platform as the financial system of record but use a specialist payroll provider that has a strong, automated accounting integration. That can give you much of the accounting convenience without forcing payroll to conform to the accounting software's limitations.

The decision scorecard

I'd score each option from 1–5 on:

1. Total annual cost
2. Accounting integration
3. Payroll tax/compliance support
4. Multi-state capability
5. HR/benefits functionality
6. Timekeeping integration
7. Reporting
8. Customer support
9. Data/security controls
10. Ability to scale

Then weight integration and compliance more heavily than price. A $50/month saving isn't meaningful if it creates several hours of bookkeeping every pay period or increases compliance risk.

Bottom line: For a small, straightforward business, integrated payroll often wins on simplicity and total administrative efficiency. As payroll becomes geographically or operationally complex, a specialized provider increasingly earns its additional cost. The important question isn't "Which payroll product is cheaper?" but "Which setup produces the lowest total cost and risk for our particular payroll?"

Comparing integrated payroll (payroll built directly into your accounting software like QuickBooks or Xero) versus a separate, dedicated payroll provider (like ADP, Gusto, or Paychex) comes down to balancing convenience against specialized capability.

Here is how a business should break down the comparison across key operational areas:

• Cost and Pricing
  • Integrated payroll: Often feels cheaper or bundled with your existing accounting subscription, though base fees or per-employee fees still apply. Watch out for hidden add-on costs for state tax filings or year-end W-2/1099 processing.
  • Separate provider: Usually a higher standalone monthly base fee plus a per-employee charge. However, they frequently offer transparent, tiered pricing that scales predictably as your feature needs grow.
• Data Flow and Efficiency
  • Integrated payroll: Seamless automation since transactions, journal entries, and tax liabilities flow instantly into your general ledger without manual data entry or third-party syncing errors.
  • Separate provider: Requires an integration or export/import process . While most major separate providers sync smoothly with top accounting tools via APIs, occasional mapping errors or sync breaks can require manual troubleshooting.
• Compliance, Tax Filing, and Risk Management
  • Integrated payroll: Handles standard federal, state, and local tax filings well, but complex multi-state compliance or niche local jurisdictions can sometimes fall outside their core automated capabilities.
  • Separate provider: Specialized expertise is their core business. They usually offer dedicated compliance guarantees, robust handling of multi-state/international tax laws, and proactive alerts regarding changing labor regulations.
• Advanced Features and Scalability
  • Integrated payroll: Best for straightforward W-2 employees and basic contractor payments . Features are streamlined and focused on simple, day-to-day operations.
  • Separate provider: Built for complex workforce needs —offering advanced HR support, workers' comp pay-as-you-go integration, time-tracking hardware/software syncs, custom employee portals, and comprehensive benefits administration (health insurance, 401(k)).
• Customer Support and Troubleshooting
  • Integrated payroll: Support is tied to your general accounting platform, which can sometimes result in longer ticket queues or generalist support reps when facing a complex payroll tax penalty or emergency.
  • Separate provider: Dedicated, specialized payroll support teams who deal exclusively with tax agencies, wage garnishments, and urgent direct-deposit fixes day in and day out.

To help narrow down the right fit, could you share:

• How many employees or contractors do you currently have?
• Do you operate in multiple states or just one?
• What accounting software are you currently using?

A business should compare integrated payroll and separate payroll providers by evaluating cost, workflow efficiency, compliance depth, and workforce complexity.

Choosing between an all-in-one system (like running payroll directly inside QuickBooks or Xero ) versus a standalone service (like Gusto, Rippling , or ADP ) shapes how easily your financial data flows and how much administrative overhead your team handles.

Key Factors to Guide Your Decision

• Workforce Complexity: If you have employees across multiple states, complex commission structures, or international contractors, a specialized standalone provider usually handles multi-jurisdiction tax registration and advanced HR compliance much better than basic accounting add-ons.
• Administrative Bandwidth: If your team lacks a dedicated HR or finance professional, keeping everything in one integrated software reduces the number of dashboard logins, reconciliation errors, and separate vendor bills.
• Cost vs. Value: For micro-businesses with simple W-2 or 1099 structures, paying for a separate heavy-duty payroll platform can be an unnecessary expense. Conversely, growing teams save more time with automated HR tools than they spend fixing integration gaps.
• Reporting and Analytics: Standalone providers frequently offer deep labor-cost reporting, workforce forecasting, and turnover metrics that outpace the basic financial statements found in standard accounting packages.

To help narrow down the best path for your organization, tell me:

• How many employees or contractors do you currently have?
• Do you operate in multiple states or countries?
• What accounting software are you currently using?

The best comparison is not simply “integrated vs. separate.” It’s really a choice between convenience and accounting integration versus payroll specialization and service depth.

When integrated payroll usually wins

Choose integrated payroll when:

• You have a small or moderately sized workforce.
• Payroll is relatively straightforward.
• You operate in one or a small number of states.
• Your accounting team values having payroll expenses, liabilities, and cash activity flow directly into the books.
• You don't need sophisticated HR/payroll functionality.
• The integrated product provides the tax filings, payments, W-2s/1099s, and support you actually need.

The biggest advantage is reducing the number of systems and handoffs. Less re-keying means fewer opportunities for payroll data and the general ledger to disagree.

When a separate provider usually wins

A dedicated provider becomes more attractive when you have:

• Multiple states or jurisdictions.
• Rapid employee growth.
• Complex overtime, commissions, bonuses, or deductions.
• Significant benefits administration.
• Timekeeping/scheduling complexity.
• Contractors and different worker classifications.
• A need for stronger payroll/HR support.
• An accounting team that doesn't want to own payroll compliance.

In other words, the more complicated payroll becomes, the more valuable specialization tends to be. Current industry guidance similarly emphasizes employee count, number of states, payroll complexity, and who owns exception handling and tax notices as key decision factors.

One important misconception

Don't assume that outsourcing payroll transfers the tax liability away from the business.

For a typical payroll service provider, the employer generally remains responsible for employment-tax obligations even when the provider prepares filings and makes deposits. The IRS specifically recommends that employers monitor their federal tax deposits through EFTPS.

There are different legal arrangements, however. For example, an IRS-certified PEO (CPEO) can assume substantially different employment-tax responsibilities from an ordinary payroll service provider.

How I'd evaluate the decision financially

Don't compare just the monthly subscription prices. Calculate:

Integrated payroll total cost = software cost + payroll administration time + compliance oversight + reconciliation time + expected error/penalty exposure

Separate provider total cost = provider fees + accounting integration/reconciliation + implementation + internal oversight

Then score each option on these five dimensions:

1. Total cost
2. Accounting/GL integration
3. Compliance risk
4. Operational complexity
5. Scalability

For a simple small business, integrated payroll often wins on total cost and simplicity. For a growing or geographically/operationally complex business, a dedicated provider can justify its additional cost by taking more payroll administration and compliance work off the accounting team.

The key question I'd put to management is:

“Do we want payroll to be an accounting feature, or do we want payroll to be a specialized business process?” If you tell me your employee count, number of states, approximate payroll frequency, and which accounting system you're using, I can build a practical integrated-vs-separate payroll decision matrix with estimated total costs and a recommendation.

Integrated payroll total cost = software cost + payroll administration time + compliance oversight + reconciliation time + expected error/penalty exposure

Separate provider total cost = provider fees + accounting integration/reconciliation + implementation + internal oversight

A business should compare integrated payroll within accounting software versus a separate payroll provider by evaluating core factors like cost, data workflow, tax liability, and HR depth.

Integrated payroll (such as running payroll directly inside QuickBooks ) keeps your ledger and employee payments in one single ecosystem. A separate payroll provider (such as Gusto or ADP ) operates as a standalone or specialized platform that syncs data over to your general ledger.

Comparison Dimensions

Detailed Breakdown

• Integrated Payroll within Accounting Software
  • Workflow Efficiency: Eliminates duplicate data entry because wages, taxes, and deductions instantly post to the correct general ledger accounts.
  • User Experience: Managed under a single login alongside profit/loss statements and bank reconciliations, reducing vendor fatigue.
  • Limitations: Advanced human resources features, employee benefit integrations, and complex multi-state tax configurations may lack the depth found in dedicated platforms.
• Separate Payroll Provider
  • Specialized Expertise: Dedicated payroll companies focus entirely on changing tax laws, workers' compensation, garnishments, and human resources administration.
  • Scalability: Better suited for high employee turnover, multi-state compliance, and robust corporate benefit packages.
  • Limitations: Requires a functioning integration bridge to your accounting software; misconfigured sync mappings can corrupt financial reporting categories.

If you can share how many employees you have , whether you operate in multiple states , and what accounting software you currently use , I can help you choose the ideal payroll setup for your business.

The best way to compare integrated payroll in accounting software versus a separate payroll provider is to treat it as a trade-off between simplicity and integration on one side, and payroll depth, flexibility, and specialized support on the other.

Side-by-side comparison

What matters most

1. Don't evaluate the subscription price alone. Calculate the total cost of ownership: payroll subscription + per-employee charges + implementation + accounting reconciliation time + tax/compliance support + costs of fixing errors.

2. Measure the quality of the accounting integration. "Integrates with accounting" can mean anything from an automatic, detailed journal entry to exporting a spreadsheet once a month. Ideally, payroll should automatically post wages, employer taxes, benefits, liabilities and other relevant items to the correct accounts.

3. Look at payroll complexity over the next 2–3 years. Integrated payroll is particularly attractive for a relatively straightforward business with one entity, one or a few states, salaried/hourly employees and uncomplicated benefits. A separate provider becomes more attractive as you add multiple states, entities, locations, commissions, bonuses, garnishments, complicated benefits or substantial HR requirements.

4. Compare compliance capabilities carefully. Payroll providers can handle withholding, reporting and tax deposits, but outsourcing does not ordinarily eliminate the employer's responsibility for federal employment taxes. The IRS specifically warns employers to monitor their provider and verify that tax deposits are being made.

5. Put a value on support. Ask: If we receive a state tax notice at 4:30 p.m. on Friday, who actually helps us resolve it? That's often more important than saving $30–$50 per month.

A practical decision rule

I'd generally use this framework:

• Choose integrated payroll if your priority is simplicity, your payroll is relatively straightforward, and your accounting system is already working well.
• Choose a separate payroll provider if payroll is becoming a specialized operational function, you have significant multi-state/complex payroll needs, or you want stronger HR/payroll expertise and support.
• Consider a separate provider even when integration isn't perfect if the provider materially reduces compliance, payroll-processing, or HR risk. A slightly less elegant accounting integration can be worth it.
• Don't switch solely because a separate provider has more features. If your business will never use those features, you're paying for complexity you don't need.

The decision matrix I'd use

Score each option from 1–5 for:

1. Payroll accuracy
2. Tax/compliance coverage
3. Accounting integration
4. Ease of administration
5. Employee experience
6. HR/benefits capabilities
7. Multi-state capability
8. Customer support
9. Security/data controls
10. Total 3-year cost
11. Scalability
12. Ease of switching later

Then weight the categories based on your business. For example, a 15-person local business might weight simplicity, cost and accounting integration heavily, while a 200-person multi-state company might put much more weight on compliance, HR functionality and scalability.

One important nuance: "integrated" doesn't necessarily mean "better payroll." It primarily means the payroll and accounting workflows are closer together. The underlying payroll engine, tax compliance, support model and HR capabilities still need to be evaluated independently.

If you tell me your company size, number of states, accounting software, and whether employees are hourly/salaried, I can turn this into a weighted decision framework and show which approach is likely to win for your situation.

A practical decision rule

A business should compare integrated payroll inside accounting software versus a separate payroll provider by looking beyond the monthly subscription price. The real decision is usually about control, complexity, compliance risk, and operational efficiency.

1. Compare the core trade-off

Integrated payroll can reduce duplicate data entry and improve payroll-to-ledger accuracy because payroll transactions can automatically update accounting records. Xero Separate providers may be preferable when payroll complexity exceeds what the accounting platform handles well.

2. Evaluate your payroll complexity

Integrated payroll is often a strong fit when you have:

• A small number of employees
• Employees in one or a few jurisdictions
• Simple hourly/salary structures
• Limited benefits administration
• A finance team already comfortable managing payroll

A separate provider may make more sense if you have:

• Employees in multiple states or countries
• Complex overtime, commissions, bonuses, or union rules
• Many benefits deductions
• Frequent hiring, terminations, or employee changes
• Need for HR features such as onboarding, time tracking, performance management, or employee self-service

3. Compare the “hidden costs”

Do not compare only:

Integrated payroll subscription vs. payroll provider fee Also estimate:

Internal labor cost

• Who enters payroll data?
• Who reviews payroll?
• Who fixes errors?
• How many hours per pay period are spent on payroll?

Compliance burden

• Who handles tax notices?
• Who monitors filing deadlines?
• Who keeps up with changing payroll rules?

Error cost

Consider the impact of:

• Incorrect paychecks
• Late tax filings
• Incorrect employee classifications
• Reconciliation problems at month-end

Payroll outsourcing often costs more in fees but can reduce administrative workload and compliance exposure.

4. Test the systems with real scenarios

Before choosing, ask vendors to demonstrate:

• Adding a new employee
• Changing an employee’s pay rate
• Processing overtime
• Running a bonus payroll
• Correcting an error after payroll closes
• Handling a terminated employee
• Reconciling payroll expenses to the general ledger
• Producing year-end reports

A system that looks simple in a demo may become difficult when exceptions arise.

5. Consider your growth plans

Choose based on where the business is heading, not only today’s needs.

Integrated payroll may win if:

• You want fewer systems
• Accounting is the operational hub
• Payroll is uncomplicated
• Your team wants simplicity

A separate provider may win if:

• Payroll is becoming a specialized function
• HR needs are expanding
• You expect rapid hiring or geographic growth
• You want access to payroll specialists

6. A practical decision rule

A rough guideline:

• 1–25 employees, simple payroll: Start with integrated payroll unless there is a clear reason not to.
• 25–100 employees or increasing complexity: Compare carefully; payroll support and HR features become more important.
• 100+ employees, multi-state, or complex compensation: A dedicated payroll/HR platform often becomes more attractive.

The best choice is the one that minimizes the total cost of running payroll correctly, not necessarily the one with the lowest software price.

A useful scoring model is to rate each option from 1–5 on:

• Cost
• Ease of use
• Compliance support
• Accounting integration
• HR capabilities
• Scalability
• Vendor support

Then weight the categories based on what matters most to your business.

A useful scoring model is to rate each option from 1–5 on:

Comparing integrated payroll (built directly into your accounting software like QuickBooks or Xero) versus a separate, standalone payroll provider (like ADP, Gusto, or Paychex) comes down to a balance between convenience, cost, compliance depth, and business complexity.

Here is a structured breakdown to help a business evaluate both options:

1. Cost and Pricing Structure

• Integrated Payroll: Often appears cheaper upfront with a low base fee plus a small per-employee cost. However, advanced features (like multi-state filing, garnishments, or HR support) may require expensive tier upgrades or add-ons.
• Separate Payroll Provider: Generally has a higher base price and per-employee fee. However, they frequently bundle complex tax compliance, worker's compensation integration, and HR tools into clearer, predictable packages.

2. Workflow and Data Entry

• Integrated Payroll: Eliminates double-entry. Payroll runs automatically update your general ledger, reconcile bank accounts, and categorize expenses in real time. This drastically reduces human error and month-end bookkeeping time.
• Separate Payroll Provider: Requires a data sync or manual journal entries. While many standalone systems offer automated integrations (syncing via API), connection errors can happen, requiring troubleshooting or manual reconciliation.

3. Compliance, Tax Filing, and Liability

• Integrated Payroll: Handles standard federal, state, and local payroll taxes well. However, if you have multi-state compliance challenges, unique local jurisdictions, or international contractors, built-in tools can sometimes lack deep customization or dedicated support.
• Separate Payroll Provider: Specialization shines here. Standalone providers live and breathe tax code updates, multi-state nexus compliance, and year-end W-2/1099 filings. They often assume legal liability or provide dedicated support teams if a tax penalty occurs due to a system error.

4. Features, HR, and Scalability

• Integrated Payroll: Best for straightforward, domestic W-2 employees and basic contractor payments. Features are typically limited to core payroll functions.
• Separate Payroll Provider: Ideal for complex organizations. They offer robust human resources information systems (HRIS), applicant tracking, benefits administration (health insurance, 401k), time-tracking hardware integration, and performance management.

Quick Comparison Matrix

Decision Framework: Which should you choose?

• Choose Integrated Payroll if: Your business is small, has a simple team structure (all employees in a single state), operates on a tight budget, and you want to minimize the number of software vendors and logins you manage.
• Choose a Separate Payroll Provider if: You operate across multiple states, employ contractors and W-2 workers with complex benefit structures, require advanced HR/time-tracking tools, or want specialized customer support to mitigate complex tax risks.

To help narrow this down, could you tell me:

• How many employees and/or contractors do you have?
• Do you operate in multiple states?
• What accounting software are you currently using?

Comparing integrated payroll (payroll built directly into your accounting software like QuickBooks or Xero) versus a separate, dedicated payroll provider (like ADP, Gusto, or Paychex) comes down to balancing convenience, cost, and advanced capabilities.

Here is how a business should break down the comparison across key categories:

• Cost and Pricing Structure
  • Integrated Payroll: Usually offers a streamlined, predictable monthly subscription fee plus a small per-employee-per-month (PEPM) charge. Because it’s bundled or added on directly to your existing software bill, it often lacks hidden implementation or integration setup fees.
  • Separate Provider: Can be more expensive, featuring base fees plus PEPM charges that scale up quickly. They may also charge extra for annual W-2/1099 processing, year-end adjustments, or adding new state tax jurisdictions.
• Data Flow and Error Reduction
  • Integrated Payroll: Data syncs automatically. When run, payroll expenses, liabilities, and cash-out flows map straight into your general ledger without manual journal entries or CSV imports, significantly lowering the risk of human data-entry error.
  • Separate Provider: Relies on an API integration or manual journal entries to push data into your accounting software. While major providers sync smoothly, connection glitches can happen, requiring occasional troubleshooting to ensure bank feeds and ledgers match.
• Feature Depth and Compliance Complexity
  • Integrated Payroll: Great for standard W-2 employees and basic multi-state processing. However, it can fall short on complex requirements like multi-location local taxes, union dues tracking, advanced garnishments, or specialized industry reporting (e.g., tipped-wage credits in hospitality).
  • Separate Provider: Built specifically to handle deep regulatory compliance, complex tax jurisdictions, international contractors, HR management, workers' compensation pay-as-you-go integration, and advanced benefits administration (401k, health insurance).
• Customer Support and Expertise
  • Integrated Payroll: Support is generally handled through the broader accounting software’s general customer service tier. Getting a true payroll tax specialist on the phone during a critical filing deadline can sometimes take longer.
  • Separate Provider: Dedicated customer support teams consisting of certified payroll professionals (CPPs) who specialize exclusively in tax codes, compliance notices, and penalty resolution.

To help narrow down the best path for your specific business, could you share:

• How many employees or contractors do you have?
• Do you operate across multiple states or localities?
• What accounting software are you currently using?

The best comparison is not simply “integrated vs. separate.” It’s really a tradeoff between simplicity and accounting integration versus payroll specialization, flexibility, and service.

Side-by-side comparison

Integrated payroll's biggest advantage is eliminating a reconciliation step. For example, modern accounting/payroll integrations can automatically create journal entries for each payroll run and keep payroll liabilities synchronized with the general ledger.

The decision criteria I would use

I'd score each option on six dimensions:

1. Payroll complexity

• Number of employees
• Number of states/localities
• Hourly vs. salaried workers
• Overtime, commissions, bonuses, tips
• Contractors
• Multiple entities
• Union or specialized pay rules

2. Compliance burden

• Who handles federal and state filings?
• Who monitors tax notices?
• Who handles new-state registrations?
• How quickly are payroll-tax changes incorporated?
• What happens when something goes wrong?

3. Accounting workload

• How much time does the accounting team spend importing/reconciling payroll?
• Does payroll automatically post correctly to the GL?
• Can payroll costs be allocated to departments, projects, locations, or classes?
• Can payroll reports reconcile cleanly to the financial statements?

4. Employee experience

• Employee self-service
• Direct deposit
• W-2 access
• PTO/time tracking
• Benefits integration
• Onboarding

5. Total cost

Don't compare just the subscription price. Calculate:

Payroll software + accounting software + implementation + accounting/reconciliation labor + compliance/admin labor + expected error costs

A “cheaper” integrated solution can become more expensive if employees spend significant time fixing payroll exceptions. 6. Risk and accountability

This is particularly important. Outsourcing payroll does not automatically transfer the employer's tax liability. The IRS says employers generally remain responsible for employment taxes even when a payroll provider handles withholding, filing, and payments.

So the business should evaluate the provider's controls, tax-payment verification, error-resolution process, and contractual responsibilities—not just its software.

A useful rule of thumb

Integrated payroll is usually the better fit when:

• The business is small or midsize.
• Payroll is relatively straightforward.
• It operates primarily in one state.
• The accounting team already lives in the accounting platform.
• Minimizing reconciliation work is a priority.
• HR functionality is relatively modest.

A separate payroll provider is usually worth considering when:

• There are employees in several states.
• Payroll rules are complicated.
• Headcount is growing rapidly.
• The company needs sophisticated HR/benefits/time functionality.
• Payroll is important enough that specialized support is valuable.
• The accounting system's payroll functionality is becoming a constraint.

One important distinction

I'd also separate “separate payroll software” from “outsourced payroll service.”

A business can use a separate payroll application while still having its accounting system receive automated payroll journal entries. That's a very different proposition from having the accounting staff manually enter payroll from an external provider.

So the real comparison can be:

Accounting + integrated payroll

vs.

Accounting + integrated external payroll

vs.

Accounting + external payroll + substantial manual processing

The third option is generally the one I'd try hardest to avoid.

For a U.S. business, I'd also make state/local tax capability a major evaluation criterion. For example, Massachusetts employers have specific withholding and reporting obligations that need to be handled correctly.

Bottom line: If payroll is simple, integration often wins because it reduces administrative friction. As payroll complexity and compliance risk increase, a specialized provider can justify its additional cost—but the business should make sure the accounting integration is robust enough that it doesn't simply move the reconciliation problem elsewhere.
