Payments

No cut of your payments

Payment QR codes send clients straight to your PayPal, Stripe, or Revolut. Inko never holds the money and takes no commission, unlike the big invoicing platforms.

Templates

Invoices that look like you

Pick a template, tune colors and fonts, rename fields, and keep your own numbering. An estimate turns into an invoice once the client signs, so you never type the same job twice.

No account. Works offline.

Open Inko and start working. There is no sign-up and no cloud. Your documents live on your device, and a basement with no signal changes nothing.
