Stack Billing
Built for people who hate doing invoices

You keep meaning to send that invoice.

If you do the work but the invoice never happens — you're not disorganized. Every invoicing app ever made was designed for someone who sits at a desk. This one wasn't.

The job is done. The money is earned. But the invoice is still sitting in your head — because sitting down to do the admin never happens. Stack Billing fixes that. No setup marathon first: open it, make the invoice, review it, send it.

Built for how you actually work — not how you planned to

For contractors and freelancers who are great at the job and terrible at the paperwork — and for whom "I'll do it later" never actually happens.

Voice Commands

No form to fill. No screen to stare at. Say what you did and it's done — before the next job starts.

Auto Check-In

Uses the same location technology already in Google Maps on your phone — only turns on when you want it to, just to know when you've arrived at a job site. Nothing else.

No Setup Marathon

You do not have to build a client list, item library, rates, or business profile before the first invoice. Fill in what matters now and clean up later.

Works without signal

Log the job the moment it's finished, signal or not. Because later never happens. The assistant needs a signal — but you don't have to wait. Log the job manually in seconds, and the assistant picks it up when you're back in range.

How it works

1

Speak. That's it.

Tap the mic and describe the job in your own words. No commands to memorize. No forms to fill. If you can say it, it's logged.

2

The assistant handles the admin

It works out the client, the hours, the rate, and the description. Even if you phrase it differently every time.

3

Review it, then send it however you want

The assistant builds the invoice in under a minute. You check it, then share the link, email it, or print it. Nothing goes to your client without you seeing it first.
