Every competitor asks you to fill in a form. Stalwa asks you to describe your work — then fills the form for you.
Type what you did
Write naturally — “Built a logo for 500, two revisions at 80 each.” No forms. No fields. Just plain English.
AI extracts every line item
Stalwa reads your description and pulls out descriptions, quantities, and rates. You review it before anything is sent.
Send a professional invoice
Tax calculated. Totals correct. Your logo on it. A secure PDF link in your client’s inbox. Done in under 2 minutes.
AI generation is a Pro feature
Stalwa extracts this
Always review before sending — AI assists, you decide.
Sound familiar?
You’re brilliant at your work. Getting paid for it shouldn’t be the hard part.
“I’m still using a Word template”
Copy last month’s invoice. Change the date. Delete the wrong thing. Re-format the total. Every single time.
Describe your work. Invoice ready in 2 minutes. Branded, professional, correct.
“Did they even get it?”
You send the invoice and then silence. Was it their spam folder? Are they ignoring it? You have no idea.
Stalwa tells you when your client opens the secure link, so follow-up feels informed instead of awkward.
“Tax time is a nightmare”
VAT? GST? Sales tax? Every year you scramble trying to figure out what rate you charged and whether it was right.
Set your country once. Stalwa auto-applies the right tax naming and default rate to every invoice.
Everything you need. Nothing you don’t.
Built for freelancers and small businesses who want to look professional — not spend their evenings learning accounting software.
