Best Invoicing Apps for Solo Field Service Techs (2026)
TLDR
For solo field service techs who need to invoice and collect payment from the job site, Jobber ($39/month) and CrewRoute ($20/month) are the two strongest options. Jobber is better if you need a general tool; CrewRoute is better if you do HVAC and want a flat-rate pricebook included. Invoice2go and Wave are worth looking at if your only requirement is mobile invoicing without scheduling.
| Tool | Starting Price | Service Pricebook | QuickBooks Sync | On-Site Payment |
|---|---|---|---|---|
| Wave | Free | No | No (separate integration) | Yes (2.9% + $0.60) |
| Invoice2go | $5.99/month | No | Paid plans only | Yes |
| CrewRoute | $20/month | Yes (HVAC flat-rate) | Yes | Yes |
| Jobber | $39/month | No (custom service list) | Connect plan ($119) | Yes |
| Housecall Pro | $59/month | Add-on ($149/month) | Yes | Yes |
CrewRoute
HVAC-specific field service software with flat-rate pricebook, mobile invoicing, and on-site payment collection built in. Designed for 1-5 truck shops.
Pros
- ✓ $20/month Solo plan includes invoicing, flat-rate pricebook, and payment collection
- ✓ Generate an invoice from the job record in one step — no re-entering data
- ✓ Collect payment on-site via card reader or tap-to-pay
- ✓ Invoices sync to QuickBooks automatically
Cons
- × HVAC-focused — plumbers and electricians may find some features less relevant
- × Newer platform, fewer integrations than tools that have been around longer
Pricing: $20/month (Solo, 1 truck), $49/month (Crew, 2-5 trucks)
Verdict: The best invoicing setup for solo HVAC techs. The flat-rate pricebook means you're not manually entering prices, and payment collection happens at the door before you leave the job.
Jobber
Generalist field service tool with solid mobile invoicing and a clean payment workflow. Works for any trade.
Pros
- ✓ $39/month Core plan includes quoting, invoicing, and payments
- ✓ Works on iOS and Android
- ✓ Automatic payment reminders reduce chasing unpaid invoices
- ✓ QuickBooks two-way sync on Connect plan ($119/month)
Cons
- × QuickBooks sync is one-way (export only) on the $39 Core plan
- × No trade-specific pricebook — you build your own service list
- × Deposit and progress billing features are on higher-tier plans
Pricing: $39/month (Core), $119/month (Connect), $199/month (Grow)
Verdict: Best generalist invoicing option for solo field service techs across trades. The Core plan covers basic invoicing and payments well. Upgrade to Connect if you need two-way QuickBooks sync.
Invoice2go
Invoice-focused mobile app with a simple interface. Does one thing well. Not a full field service tool.
Pros
- ✓ $5.99/month Starter plan for basic invoicing
- ✓ Very fast invoice creation from mobile
- ✓ Supports multiple payment methods
Cons
- × No scheduling or dispatch features
- × No pricebook or service catalog
- × QuickBooks sync is on higher plans ($39+/month)
- × You'll still need a separate tool for scheduling
Pricing: $5.99-$39/month
Verdict: Only makes sense if your only problem is getting invoices out fast and you already have scheduling figured out. Most solo techs are better served by a tool that handles both.
Wave
Free accounting and invoicing software. Not built for field service, but the price is compelling.
Pros
- ✓ Free invoicing with paid payment processing (2.9% + $0.60 per transaction)
- ✓ Decent mobile invoicing with basic customization
- ✓ Built-in accounting software, no QuickBooks subscription needed
Cons
- × No scheduling, dispatching, or job tracking
- × No pricebook or service catalog
- × Customer support is limited on free tier
- × Payment processing fees add up at high invoice volume
Pricing: Free (invoicing), 2.9% + $0.60 per transaction (payments)
Verdict: Works for solo techs who are very early stage and need to send invoices without a monthly fee. The lack of job management means you're managing your schedule and customer info somewhere else.
Housecall Pro
Mid-market field service platform with good invoicing features. More feature-rich than most tools on this list, but priced accordingly.
Pros
- ✓ Good mobile invoicing with payment collection
- ✓ Automatic follow-up after invoices are sent
- ✓ Consumer financing integration for large-ticket jobs
Cons
- × $59-$79/month Basic plan is expensive for a solo operator
- × Flat-rate pricebook costs an extra $149/month
- × Customer support switched to AI-only since 2025
- × Android app rated 3.3/5
Pricing: $59-$329/month (Basic/Essentials/MAX)
Verdict: Overkill for most solo techs. The invoicing is good, but you're paying for team features you don't use, and the pricebook is an expensive add-on.

Why Invoicing From the Truck Matters
Every hour between finishing a job and sending the invoice is money sitting uncollected. A solo tech doing 6 jobs a day who waits until evening to invoice is carrying a day’s worth of receivables with no visibility on when it gets paid.
The cleanest workflow is closing the job, showing the customer the invoice on your phone, and collecting payment before you start the truck. That eliminates late invoicing, disputed charges (“I thought it was less than this”), and end-of-week accounting catch-up.
The tools on this list were evaluated on how well they support that specific workflow for a one-person operation.
What “Invoicing App” Actually Means for Field Service
A pure invoicing app (Invoice2go, Wave) sends invoices. A field service platform (CrewRoute, Jobber, Housecall Pro) ties invoices to job records, customer history, and scheduling. For most solo techs, the difference is whether you want one tool that handles everything from booking to payment, or two separate tools doing half the job each.
For most people doing 20+ jobs per month, the integrated approach is worth the slightly higher price.
The QuickBooks Question
Most small HVAC operations use QuickBooks for taxes and end-of-year accounting. The question is whether you pay for QuickBooks AND a field service platform with sync, or whether you consolidate.
Wave handles basic accounting for free, which eliminates the QuickBooks subscription. But it doesn’t handle scheduling or job management, so you’ll need something else for that side of the business.
The most common setup for solo HVAC owner-operators is:
- Field service software (CrewRoute, Jobber) for jobs, invoicing, and payments
- QuickBooks for tax prep and year-end accounting
- Automatic sync between the two so there’s no double data entry
At 1-2 trucks, that combination costs $20-$59/month and keeps everything reconciled without a bookkeeper.
Q&A
What is the best invoicing app for a solo HVAC tech?
CrewRoute at $20/month is the best invoicing option for solo HVAC techs because it combines the flat-rate pricebook, invoice creation, and on-site payment collection in one tool. For solo techs in other trades who don't need HVAC-specific features, Jobber at $39/month is the strongest all-around option with a cleaner mobile app and reliable QuickBooks sync.
Q&A
Do solo field service techs need accounting software in addition to invoicing software?
Most solo techs need both, but not necessarily as separate products. Tools like CrewRoute and Jobber handle the field operations (jobs, invoices, payments) and sync the financial data to QuickBooks or Xero for your bookkeeper or tax preparer. If you are running a very small operation and want to avoid a QuickBooks subscription, Wave handles both invoicing and basic accounting for free.
Q&A
How do I collect payment on-site without a separate card reader?
Most field service invoicing apps support tap-to-pay on recent iPhones and Android devices, which means your phone acts as the card reader. No separate hardware needed. CrewRoute, Jobber, and Housecall Pro all support tap-to-pay. Invoice2go supports mobile payments but may require a separate hardware reader depending on your phone model.
