For a service-based agency, I’d prioritize software that handles client invoicing, recurring billing, time/project tracking, expenses, bank reconciliation, and profitability reporting—not just basic bookkeeping.
My shortlist
| Software | Best for | Agency fit |
|---|
| QuickBooks Online | Best overall / accountant-friendly | ⭐⭐⭐⭐⭐ |
| Xero | Project-based agencies & strong reporting | ⭐⭐⭐⭐⭐ |
| FreshBooks | Simple client invoicing & time tracking | ⭐⭐⭐⭐ |
| Zoho Books | Value-conscious agencies wanting a broader Zoho ecosystem | ⭐⭐⭐⭐ |
1. QuickBooks Online — my default recommendation
If your goal is to run the agency's finances, rather than simply send invoices, I'd start here.
It gives you the conventional accounting foundation—income/expense tracking, bank feeds and reconciliation, financial reports, taxes, etc.—while supporting customer/project time tracking and billing. QuickBooks' current documentation confirms time tracking can be used to track and bill customers for hours spent on projects.
I'd choose it if: you have an accountant/bookkeeper, expect the agency to grow, or want your financial system to be fairly standard and transferable.
2. Xero — particularly good for project-based agencies
Xero is arguably the strongest alternative for an agency that cares about project profitability.
Its Projects functionality connects estimates, staff time, expenses, invoices and project profitability. You can see what a project has cost versus what you've invoiced and generate invoices from project information.
I'd choose it if: you want to answer questions like "Which clients/projects are actually profitable?" without stitching together several systems.
3. FreshBooks — easiest for client billing
FreshBooks is especially appealing if invoicing is the center of your workflow. It lets you track billable time and expenses and turn those into invoices; it also supports recurring invoices, online payments and late-payment reminders.
Its project functionality also keeps client projects, time, invoices and expenses together.
I'd choose it if: you're a smaller agency and want something your team can adopt quickly without feeling like they're learning an accounting system.
What I'd pick for an agency
If I were setting this up today:
- Small agency / primarily fixed-fee retainers: QuickBooks Online
- Agency with lots of projects + need for profitability by client: Xero
- Solo/small creative agency where invoicing simplicity matters most: FreshBooks
- Already heavily invested in Zoho: Zoho Books
One important consideration: don't choose solely based on the prettiest invoicing interface. For an agency, I'd make sure the system can distinguish revenue by client, direct labor, subcontractors, overhead, billable vs. non-billable time, accounts receivable, and project/client profitability.
If you tell me (1) number of employees, (2) approximate annual revenue, (3) whether you bill hourly or fixed-fee/retainer, and (4) whether you already use an accountant/bookkeeper, I can narrow this down to the best 1–2 options and the specific plan I'd choose.
