The invoice app that doesn’t count your invoices.

No cap, no watermark, no account, no internet needed. Free forever — not a trial.

Coming to Google Play

Android 8.0 and up. Nothing to sign up for.

Built for plumbers, electricians, builders and freelancers — people who write an invoice standing next to the job, not sitting at a desk.

What your customer receives

A business document, not a printout of a form.

Bilva builds the invoice from what you enter — parties, items, tax treatment, payment terms — and lays it out to the same rules every time. It prints legibly in greyscale.

Re-typeset from SPEC §6 at true A4 proportion — not a screenshot. On a phone this is cropped to the top of the page; swipe across it, or open the site on a wider screen to see the whole document.

What costs nothing

Unlimited invoices and estimates

No monthly allowance and no counter anywhere in the app. Write twelve in an afternoon if that is the afternoon you are having.

No watermark

Nothing on the document says which app made it. Your customer sees your business and nothing else.

No account

No email, no password, no sign-in. Install it and the first invoice starts immediately.

Works fully offline

Everything runs on the phone. A basement with no signal is a normal place to work.

Tax handled the way your jurisdiction writes it

VAT, GST and invoice numbering follow the rules of the place you work in, across six jurisdictions. Exempt and zero-rated lines, inclusive or exclusive pricing, reverse-charge wording where it applies.

Bilva does not give accounting or tax advice. These rules are a convenience, not a compliance guarantee — your accountant remains responsible for what you file.

If you ever want more

Pro is $24.99 a year and adds five things: multiple businesses, client signature, deposits, custom invoice templates, encrypted backup. One plan. Cancelling takes one tap.
