This is the real input. No form. No client setup screen. No template picker. Your client details are remembered from the first invoice onward.
We signed up to the two most popular tools and counted. One made us pass 10 screens before we could touch an invoice: company form, phone number, account verification, template picker, module checklist.
The other greeted us with a blank form: upload a logo, create a client, pick dates, add lines. Its online payments setting? Switched off by default.
You have three clients, not a finance department. Invoicing should take the time of writing a text message.
"Invoice Sarah $600 for the March website work." The invoice appears on screen with the amount, tax, number, and due date filled in. New client? Add their details once (email, VAT number if they have one, tax setting) and it's remembered forever.
You see the invoice before it goes anywhere. Everything is tap-to-edit. One tap sends it. Your client gets it by email with a pay-by-card button, no account needed.
Card payments land in your own Stripe account. We never touch your money. If the invoice runs late, a polite reminder goes out for you, automatically.
