I'm looking for a simple quoting software for our service business that's easy to use on the go.

If your priority is simple quoting from your phone while you're out on jobs, I’d look at these three:

• joist.com — Probably the simplest starting point. It’s focused on estimates, invoices, payments, and customer/job information rather than trying to be a huge business-management system. It has iOS/Android apps, and you can turn an estimate into an invoice with one tap. Current pricing starts around $10/month according to Joist’s 2026 comparison.
• getjobber.com — Better if you want quoting plus scheduling, customer management, job tracking, invoicing, and follow-ups. Its mobile app lets you build quotes on-site, and approved quotes can flow into jobs.
• housecallpro.com — Worth considering if you're running a growing home-service operation with multiple technicians. It combines estimates with scheduling, dispatch, payments, and other field-service features, so it's more extensive than a basic quoting app.

My quick way to narrow it down

Solo operator / small crew → Joist Service business with scheduling and several employees → Jobber Growing home-service company with dispatch/technician management → Housecall Pro

If you tell me what type of service business you run, how many people are in the field, and whether you need scheduling/invoicing too, I can narrow it down to the best 1–2 options and compare the current pricing.

When you're running a service business on the move, you need something that lets you build and fire off a professional estimate from your truck or a customer's driveway in under two minutes—without getting bogged down by massive enterprise field-service suites.

Here are top, streamlined options optimized for mobile quoting and ease of use:

• QuoteIQ — Purpose-built specifically for mobile service operators and field contractors. It shines on the go with fast, streamlined estimating, easy mobile-first layout, and built-in tools like route tracking and quick customer communication right from your phone.
• FreshBooks — Excellent if you want a clean balance between simple on-the-site quoting, expense tracking, and mobile invoicing. You can draft, customize, and text or email quotes right from the FreshBooks Mobile App , then convert them to invoices the second the client gives the green light.
• Xero — While technically cloud accounting software, its mobile app functions brilliantly as a pocket quote and invoice book. It’s ideal if you want to keep your numbers straightforward and let an apprentice or field tech punch up an estimate on-site while keeping your back-end financials synced.
• PandaDoc — Great if your quotes need to look ultra-polished with integrated e-signatures. While powerful on desktop, their mobile capability allows you to track document status, send quick quotes, and get immediate client sign-offs while out in the field.

To help narrow down the best fit, tell me:

• What specific type of service business do you run (e.g., contracting, cleaning, mobile detailing, consulting)?
• Do you need the app to also handle scheduling and invoicing , or strictly just quoting?

If your main goal is “I’m at the customer’s house, I need to build a quote quickly and send it from my phone”, I’d keep the shortlist pretty small.

My top picks

• Joist — simplest choice. It’s built specifically around estimates → invoices → payments, with a mobile app for iOS and Android. Its current entry pricing is around $10/month, and there’s a 14-day trial. This is where I’d start if you don’t need a complicated CRM or dispatch system.
• QuoteIQ — best if you want quoting plus more business management. Its Essentials plan is currently $29.99/month for one user, with estimates, invoices, payments, scheduling, a price book, e-signatures, and iOS/Android apps. It is particularly mobile-focused.
• Jobber — best if you're going to grow into scheduling/dispatch. It goes beyond quoting into customer management, scheduling, jobs, invoicing, payments and communication. It has iOS and Android apps, but it's more of a full field-service platform than a lightweight quoting app.

What I'd choose

For “simple + easy on the go,” my first trial would be Joist. You can create/send estimates from the jobsite without buying into a huge field-service system.

If you tell me what type of service business you run (landscaping, HVAC, cleaning, electrical, painting, remodeling, etc.) and roughly how many people need to use it, I can narrow this down to the best 2–3 options for your workflow.

When you’re running a service business and need to shoot over an estimate from your phone before you even pull out of a client’s driveway, you want something stripped down to the essentials—no clunky desktop layouts or heavy accounting bloat.

Here are the top simple, mobile-friendly options that let you build and text/email professional quotes on the go:

• Jobber — Purpose-built for field service businesses [18] (landscaping, cleaning, HVAC, contracting [18], etc.). Its mobile app excels at letting you put together a clean quote with optional line items [17], get instant online client approval [17], and convert it straight into a job or invoice [17]. You can check it out on Jobber [18].
• Invoice2go — If you want the absolute fastest, lowest-learning-curve way to pick a template, drop in line items, and text or email a quote from your phone, this is a strong contender. It’s designed specifically for mobile-first workflows and lets clients tap to approve and pay. Learn more at Invoice2go.
• Zoho Invoice — A lightweight, user-friendly choice if you want professional estimates without paying a premium. The mobile app lets you generate on-site quotes, apply taxes, and email PDFs instantly. Details are available through Zoho Invoice.
• Quote IQ — Highly popular for mobile service and detailing pros who need quick, on-the-spot estimates. It lets you add custom line items and photos right from your phone, capture e-signatures, and convert quotes into invoices immediately. You can look into it via Quote IQ.

To help narrow this down, tell me:

• What specific trade or service does your business provide?
• Do you also need it to handle scheduling and dispatching , or just quotes and invoicing?

When you are running a service business out in the field, you need something that lets you pull out your phone, punch in a few line items, and text or email a sharp-looking quote before you even walk back to your truck.

Here are the top, straightforward options designed specifically for quick mobile quoting and seamless transition to invoices:

1. Invoice Simple
   • Best for: Pure, no-fuss speed on mobile.
   • Why it works: It strips away heavy desktop accounting clutter and focuses strictly on estimates, quotes, and invoices. You can build a professional, itemized quote in under a minute on iOS or Android, let the client sign off, and convert that estimate into an invoice with a single tap.
   • Learn more: Check out the mobile overview on Invoice Simple.
2. Jobber
   • Best for: Field service businesses (landscaping, contracting, HVAC, cleaning).
   • Why it works: If you do more than just quote—like scheduling jobs or managing a route—Jobber has an exceptionally clean mobile app. It allows you to create quotes with optional add-on line items, triggers automated text follow-ups to clients, and lets customers approve quotes online.
3. Invoice2go
   • Best for: Small service teams and sole operators who want a polished look without a learning curve.

To help narrow down the best fit, tell me:

• What specific type of service do you provide (e.g., cleaning, contracting, consulting)?
• Do you also need it to handle scheduling and calendar management , or just quotes and invoices?

If your priority is simple quoting that you can do from your phone while you’re out on jobs, I’d shortlist these:

• Joist — My first choice if quoting is the main need. It’s built around estimates, invoices, payments, and client management, and you can create/send professional quotes directly from your phone. It also lets you save templates and frequently used items.
• Jobber — Better if you want quoting plus scheduling, customer management, follow-ups, and invoicing. Quotes can include optional items, photos, approvals, deposits, and automated follow-ups.
• Housecall Pro — A stronger choice if you're running a growing home-service team and want the quoting system tied closely to scheduling and dispatch.
• QuoteIQ — Worth considering if you want a more feature-heavy service-business platform, including quoting, scheduling, payments, and AI-assisted estimating. Its entry plan is currently listed at $29.99/month.

My pick

Start with Joist if you mainly need: “I'm standing at a customer's property → make a quote → send it → get approval/payment.” It has a relatively low-cost entry point and is deliberately focused on contractors rather than trying to be a giant business-management system.

If you tell me what kind of service business you run, how many people are on the team, and roughly how many quotes you send per week, I can narrow this down to the best 1–2 options for you.

If you want something fast, highly mobile-friendly, and free of the bloat found in heavy enterprise ERPs or complex accounting platforms, a few standout mobile-first options fit right into an on-the-go workflow:

• Square Invoices : Exceptionally mobile-friendly with a robust free tier. You can whip up professional estimates straight from your phone, text or email them to clients, and instantly convert them to invoices the second they give you the green light.
• Invoice Simple : True to its name, this app lets you build, manage, and text or email estimates/quotes from iOS or Android in seconds. It saves your standard items and client details, handles e-signatures or tap-to-approve, and transitions a quote into an active invoice with a single tap.
• Quote IQ : Built specifically for service contractors in the field. It lets you put together line-item estimates from your phone, attach job photos on the fly, collect e-signatures, and even features built-in property measurement tools if you need quick square-footage estimates on location.
• Wave Financial : Great if you want a clean dashboard that handles free unlimited estimates and invoicing on the go alongside basic income tracking without a monthly subscription fee.

To help narrow down the best fit, tell me:

• Do you need client e-signatures and on-the-spot credit card payments?
• Are you quoting simple flat rates/hourly work , or do you need satellite/measurement tools for properties?
• Are you looking for a completely free basic tier or a paid tool with advanced scheduling?

If your main goal is “I’m standing at the customer’s property and want to make a professional quote from my phone in a couple of minutes,” I’d keep the shortlist very small.

My top picks

• Joist — best for simplicity. It focuses on estimates, invoices, payments, clients, and basic job management rather than trying to become your entire business-management system. It has full iOS/Android functionality and is specifically designed for use from the jobsite.
• Jobber — best if you also need scheduling. You can create quotes directly in its mobile app, using templates or starting from scratch, and it connects quoting with scheduling, invoicing, customer management, and follow-up.
• Housecall Pro — best for a growing service crew. It's more comprehensive, with estimating, scheduling, dispatch, payments, and customer communication. That makes it more powerful, but also more software than I'd buy if quoting is your primary need.

What I'd choose

Solo or small service business → Joist. Small team where scheduling/dispatch matters → Jobber. Several technicians and you want an all-in-one system → Housecall Pro.

Joist is particularly compelling for your description: current pricing information shows plans starting around $10/month, with a 14-day trial, while Jobber starts around $49/month and Housecall Pro is considerably more.

If you tell me what type of service business you run, how many people are in the field, and whether you need scheduling/invoicing/payments too, I can narrow this down to the one I'd pick for you.

QuickBooks Online, Invoice2go , and FieldPulse are three of the simplest quoting and invoicing software options designed with robust mobile apps for creating and sending estimates on the go.

To help narrow down the best choice, tell me:

• What specific industry is your service business in (e.g., contracting, cleaning, consulting)?
• Do you also need to collect payments or schedule jobs directly from your phone?

If simple quoting + mobile/on-the-go use is your priority, I’d start with these:

• joist.com — Best for simplicity. It’s built around estimates, invoices, payments, and basic job management rather than trying to be an entire business operating system. You can create professional quotes from your phone, use saved items/templates, collect signatures, and turn an approved quote into an invoice.
• getjobber.com — Best if you need more than quoting. Its mobile app handles quotes, scheduling, invoicing, customer communication, and payments. It’s more comprehensive, but consequently less minimalist than Joist.
• Housecall Pro — Worth considering if you have multiple technicians and want dispatching/scheduling alongside estimates. Joist itself describes Housecall Pro as being geared toward running and scaling a whole service business, whereas Joist focuses more tightly on quote-to-payment.

My pick

I'd try Joist first. It sounds closest to what you're asking for: open the app → build a quote → send it to the customer → get approval → invoice. It has a 14-day trial with no credit card required.

If you tell me what kind of service business you run, how many people are in the company, and whether you need scheduling/invoicing too, I can narrow it down to the 2–3 best options and compare their current pricing/features.
