What does Wow Invoice do?
You make an invoice or an estimate on your phone and send it by text or email. Your client opens it from a link in any browser and can pay by card, Apple Pay or Google Pay. When the client says yes to an estimate, you turn it into an invoice with one tap.
Who is it for?
Small business owners, contractors, freelancers and trades: electricians, plumbers, builders, roofers, painters, mechanics and shops.
How do card payments work?
Through Stripe. You connect your own Stripe account in the app, and the money goes to your bank. Cards are entered on Stripe’s page, so we never see or store card numbers. Invoices mark themselves paid.
Does my client need the app?
No. Clients open your invoice from a link in any browser and pay from there.
Where does it work?
Small business owners in 150 countries use Wow Invoice. It works in English, Spanish, French, German and Italian, with over 135 currencies.
What does it cost?
Wow Invoice is free to download on the App Store and Google Play. The free invoice maker on this website needs no sign-up.
Can I use it on a computer?
Not yet. Wow Invoice is on iPhone and Android today, and a web version is on the way. Your clients can already open your invoices on any computer.
