You finished the job. The customer is happy. And now you need to get paid.
If your invoicing process involves driving back to the office, typing up a bill in QuickBooks, emailing it, and then waiting two to four weeks for payment — you’re leaving money on the table every single day.
The best invoicing software for contractors lets your techs create and send invoices on-site, collect payment before they leave, and automatically sync everything with your accounting system. No double entry. No chasing. No, “I’ll send that invoice when I get back to the shop.”
This guide compares the tools that actually work for plumbers, HVAC techs, electricians, and other trade contractors in the field.
What Contractors Actually Need From Invoicing Software
Before comparing tools, here’s what matters in the real world — not on a feature comparison page, but when your tech is standing in a customer’s kitchen at 4:30 PM on a Friday:
| Must-Have | Why It Matters |
|---|---|
| Mobile invoicing | Techs create invoices from their phone or tablet, on-site, without calling the office |
| On-site card payments | Collect payment before the tech leaves. Tap, chip, or manual entry |
| Offline capability | Invoicing works in basements, rural areas, and anywhere with no cell signal |
| Auto-populated line items | Invoice pulls from the work order — parts, labor, and notes already filled in |
| Automatic payment reminders | The system follows up on unpaid invoices at 3, 7, and 14 days without your office staff doing it manually |
| QuickBooks/Xero sync | Invoice data flows to your accounting software without double entry |
| Professional appearance | Clean, branded invoice with your logo that doesn’t look like it came from a spreadsheet |
If a tool doesn’t cover these basics, it doesn’t matter how many other features it has. Your techs won’t use it, your office will still be chasing payments, and your cash flow will continue to suffer.

1. RevoField — Best All-in-One Invoicing for Field Contractors
RevoField isn’t just invoicing software — it’s a complete field service platform where invoicing is deeply integrated into the job workflow. The invoice builds itself as your tech works.
How the Invoicing Workflow Works
- Tech arrives at the job and opens the work order on their phone
- As they work, they log time, add parts from the pre-loaded inventory, and take photos
- When the job is done, they tap “Create Invoice” — line items, labor, tax, and totals are already calculated
- Customer reviews and pays on the spot via card tap or chip
- Receipts send automatically. Data syncs to QuickBooks. Done.
The entire process takes less than two minutes and works completely offline.
Key Invoicing Features
- Offline invoicing and payment. Create invoices and capture card payments with zero internet connection. The transaction queues and processes when the phone reconnects.
- Auto-populated from work orders. No retyping. Parts, labor hours, and service descriptions are automatically transferred from the job record to the invoice.
- Branded templates. Your logo, your colors, your business info. Use a professional field service invoice template or customize your own.
- Automated reminders. Set up automatic follow-ups for unpaid invoices. The system handles the awkward “just following up” emails so your team doesn’t have to.
- Customer portal payments. Customers can view and pay invoices through their online portal anytime — no phone calls, no “can you resend that?”
- Recurring invoicing. For maintenance contracts and recurring service agreements, invoices generate and bill automatically on schedule.
Pricing
$49/month for up to 5 users. All invoicing features included — no premium tier required. See full pricing.

2. Jobber — Best for Simple, Straightforward Invoicing
Jobber does invoicing cleanly and simply. If you want to create a quote, convert it to a job, and then convert the job to an invoice with minimal clicks, Jobber handles that well.
Strengths
- Clean invoice creation with professional templates
- Quote-to-invoice conversion in a few taps
- Batch invoicing for multiple completed jobs
- Strong QuickBooks Online integration
- Client hub where customers can view and pay
Weaknesses
- Offline invoicing is limited — techs need connectivity to create and send
- Automated follow-ups only available on higher-tier plans
- No inventory tracking, so parts aren’t auto-populated from stock
- Per-user pricing means invoicing costs scale with team size
Best For
Small teams (1-5 people) who do straightforward residential service work and always have cell signal on site.
3. Housecall Pro — Best for Getting Paid Fastest
Housecall Pro stands out for one thing: InstaPay. You can get your money the same day instead of waiting for standard payment processing times.
Strengths
- InstaPay same-day deposits (for a fee)
- Automatic invoice generation from completed jobs
- Built-in tipping feature (good for service-oriented businesses)
- Consumer financing options through the Wisetack partnership
Weaknesses
- InstaPay charges a percentage fee on top of standard processing
- Offline capability is limited
- Invoice customization is somewhat restricted
- Per-user pricing
Best For
Contractors with tight cash flow who need same-day access to completed job revenue.
4. FreshBooks — Best for Contractors Who Want Accounting Built In
FreshBooks is accounting software that happens to have good invoicing. If you want to ditch QuickBooks entirely and handle accounting plus invoicing in one system, FreshBooks is worth considering.
Strengths
- Full accounting system (profit & loss, expense tracking, tax categories)
- Clean, professional invoice templates
- Automatic late payment reminders
- Time tracking is built in
- Client portal for invoice viewing and payment
Weaknesses
- Not built for field service — no scheduling, dispatch, or work order management
- No offline mode
- No mobile payment collection on site
- You’ll still need a separate tool for job management
Best For
Solo contractors who want invoicing and basic accounting in one tool and don’t need field service management features.
5. QuickBooks — Best If You’re Already Committed to the Ecosystem
If your accountant uses QuickBooks and your entire financial history lives there, using QuickBooks invoicing means zero data syncing issues. But it’s accounting software trying to be invoicing software — not a field service tool.
Strengths
- Your accountant already knows it
- No data sync issues — everything is in one system
- Decent mobile invoicing through the QuickBooks app
- QB Payments for card processing
Weaknesses
- No work order integration — invoices are created from scratch, not from completed jobs
- No offline capability
- No scheduling, dispatch, or field service features
- The mobile app is designed for accounting, not for techs in the field
Best For
Contractors who handle fewer than 10 jobs per week and want everything in QuickBooks without adding another tool.
The Real Cost of Bad Invoicing
Slow invoicing doesn’t just delay your cash flow — it costs you real money. Here’s what contractors typically see before switching to proper invoicing software:
| Metric | Manual / Delayed Invoicing | On-Site Mobile Invoicing |
|---|---|---|
| Average days to payment | 25–45 days | 0–5 days |
| Invoices paid the same day | 5–15% | 70–85% |
| Admin hours/week on invoicing | 8–12 hours | 1–2 hours |
| Write-off rate (uncollected) | 2–5% | Under 1% |
| Cash tied up in receivables | $50K–$200K+ | $10K–$30K |
