"They recently reduced the number of invoices per month to THREE. That's PAID… Slimy."Invoice Simple review · May 2026
"I'm retiring now and must pay a monthly fee to access records I paid a monthly fee to create. EXTORTION!!!"Joist review · May 2026
"I have been using this app for 11 years. I paid for the app. And now you're deciding to start charging a subscription."Invoice Simple review · April 2026
We read about 200 of these. Then we built the opposite.
Import from Contacts once. They autofill forever — name, address, the lot.
Saved items type ahead. Tax and totals calculate live, to the cent, with the accountant's double rule.
A clean PDF with your logo, payment links and a QR code. Text it, email it, print it. It's saved to your Files — forever.
Invoices and estimates with no monthly caps. Estimates convert to invoices in one tap when the job's approved.
Every document is a real PDF in your Files app and iCloud Drive. Delete the app — your paperwork stays.
Venmo, PayPal, Zelle, your Stripe link — printed on every invoice with a QR code. We never touch the money.
Fully offline. Big buttons. A new invoice is one tap from anywhere — gloves on.
Outstanding, overdue and paid-this-month at a glance. Partial payments tracked to the cent.
CSV of everything, PDF archive, one tap. Your data walks out the door with you any day — that's the point.
Invoice Simple charges about $200 a year — and caps paid plans at 3 invoices a month. We charge once.
Your phone falls off a ladder. Your invoices shouldn't go with it. Cancel anytime — your data and exports never depend on it.
Yes. Slap Pro is $49.99 once and unlocks unlimited invoices and estimates forever. There is no subscription required. An optional Slap Cloud subscription ($4.99/month) adds iCloud backup and multi-device sync, but it never gates access to your invoices or exports.
On your phone. Every invoice generates as a PDF saved to your iPhone's Files app and iCloud Drive. There is no account and no company server, so your documents stay yours even if you delete the app or stop paying for anything.
Your first 3 documents are fully featured and free. For everyone, PDF export and sharing plus CSV export of all your data are free forever. The free tier never shrinks.
No. Slap Invoice prints your own payment links — Venmo, PayPal, Zelle or your Stripe link — with a QR code on every invoice. Money goes straight from your client to you. Slap Invoice never processes or touches the payment.
Slap Invoice is built natively for iPhone (it also runs on iPad). There is no Android or web version planned until the iPhone app is excellent.
Solo tradespeople and small operators — handymen, plumbers, electricians, landscapers, cleaners, contractors and freelancers — who send a handful of invoices and estimates and want to own their records without a monthly subscription.
