InvoiceASAP Review — Mobile Invoicing for Contractors Who Want to Get Paid Before They Leave the Job Site

Real Pricing

⚠ Free tier charges $0.25 per invoice. Growth and Business include unlimited invoices. Payment processing: 2.9% + $0.30 per transaction. QuickBooks Online sync requires at least the Growth tier. Works offline and syncs when you're back in range.

What It Actually Does

InvoiceASAP solves the single most annoying financial problem in the trades: invoicing from the job site instead of at 9 PM when you finally get home. You open the app on your phone, build an invoice with your services and pricing, hand the phone to the customer for a signature, and either take payment on the spot or send the invoice by email or text. Everything syncs to QuickBooks Online automatically so you don’t enter anything twice.

The mobile-first design matters. This wasn’t built as desktop software that got squeezed onto a phone screen. Every button, every field, every step in the process was designed for someone standing in a driveway or a basement holding a phone with one hand. You can build and send an invoice in about 60 seconds once you have your service catalog set up.

The QuickBooks sync is what separates InvoiceASAP from simpler options like Square Invoices. When you send an invoice through InvoiceASAP, the customer, the line items, the payment status, and the transaction all appear in QuickBooks automatically. No exporting CSV files. No manual entry. No reconciling two systems at the end of the month. For anyone who has ever spent a Sunday afternoon matching invoices to QuickBooks transactions, that alone is worth the $15 a month.

The offline capability deserves a mention too. You can create invoices when you don’t have cell service — basements, rural job sites, big metal buildings — and they sync automatically when you’re back in range. The customer still gets their invoice. You still get your QuickBooks entry. It just happens a few minutes later.

The Pricing That Actually Works

InvoiceASAP’s pricing is refreshingly straightforward. The free Starter tier lets you send as many invoices as you want at 25 cents each. If you send 20 invoices a month, that’s $5 total. For a solo operator or part-time contractor, that’s perfectly reasonable. You only upgrade when the math stops making sense — around 60 invoices a month, where $15 for unlimited invoicing is cheaper than 60 times 25 cents.

The $15 Growth tier is where most contractors should land. Unlimited invoices, QuickBooks sync, and the basic features you’ll actually use. The $30 Business tier adds advanced reporting and some customization options that most small shops don’t need.

Payment processing is standard industry pricing. Credit cards cost 2.9 percent plus 30 cents per transaction. ACH bank transfers are cheaper but take a few days to clear. InvoiceASAP doesn’t mark up the processing fees — you pay what the payment processor charges.

Who Should Use It

InvoiceASAP makes the most sense for contractors who already have a system for scheduling and customer management but want better invoicing. If you use Jobber or Housecall Pro for everything else but their invoicing feels clunky, InvoiceASAP can handle just the invoicing piece and sync the results to QuickBooks.

Electricians and HVAC contractors doing service calls benefit from invoicing on-site. The emotion of a well-done job is fresh. The customer is standing right there. They sign on your phone and either pay immediately or get the invoice while they’re still thinking about how happy they are with the work. Invoices sent later that evening get paid slower.

Plumbers doing emergency work should invoice on-site whenever possible. Emergency plumbing is the highest-emotion trade interaction. The customer is thrilled you showed up and fixed the problem. Invoice and get paid before that emotion fades.

Pool service techs and landscapers with recurring customers benefit from the QuickBooks sync more than the on-site invoicing. Monthly billing for maintenance contracts syncs automatically to QuickBooks without manual entry.

Pool contractors doing multi-stage construction projects should skip InvoiceASAP. Progress billing by milestone is better handled in QuickBooks Online directly or through your project management software.

From the Trenches

The single biggest change InvoiceASAP makes to your business is that invoices go out immediately instead of eventually. Every contractor knows the feeling of getting home at 8 PM after a 12-hour day, seeing five jobs worth of paperwork that needs invoicing, and deciding it can wait until tomorrow. Tomorrow becomes the weekend. The weekend becomes next week. And customers who don’t receive invoices don’t send payments.

When invoicing takes 60 seconds on your phone before you even leave the job site, that backlog never builds up. Every job gets invoiced. Every invoice gets paid faster. Your cash flow improves not because customers pay quicker — though they often do when the invoice arrives while they’re still happy about the work — but because invoices go out on time instead of piling up on your desk.

The QuickBooks integration is the feature that matters most in practice. If you’re currently entering invoices into QuickBooks by hand after sending them through another system, InvoiceASAP eliminates that step entirely. That’s hours a month you get back, and more importantly, your QuickBooks file is always current instead of always being a few weeks behind. Your accountant will notice the difference. So will your blood pressure at tax time.

Alternatives

• Cheaper: Square Invoices (free, pay-per-transaction only)
• Simpler: Joist (free tier, focused on estimating plus invoicing)
• More powerful (and more expensive): Jobber or Housecall Pro (full field service management with invoicing built in)
