The problem
Invoicing is the job after the job. You finish on site, you're tired, and the paperwork gets pushed to Friday night, or the weekend, or whenever there's a spare hour at a desk.
Every day an invoice sits unsent is a day you're not getting paid for work you've already done.
How it fixes it
Invoice Studio is a mobile app for sending professional invoices and quotes from your phone. You open it, fill in the job, pick a template, and send a PDF. That's the whole thing.
What lands in your client's inbox is a proper document with your logo and colours on it, not a photo of a handwritten docket or a spreadsheet with your name typed at the top.
It's built for the moment the job finishes rather than the moment you get back to a desk, so it does the small things that make that possible:
- Six templates, with your logo and colours on every document
- A quote becomes an invoice in one tap, with nothing re-typed
- Saved clients and line items, so repeat work is a few taps
- GST, VAT, sales tax and IVA handled properly, inclusive or exclusive
- Draft, issued, paid, overdue at a glance, so you know who still owes you
- Works with no signal, because plenty of jobs don't have any
There's no account to make and nothing to subscribe to before your first invoice. You install it and you use it.

Who it's for
Sole traders, tradespeople, contractors, and freelancers. Anyone who invoices between jobs rather than at a desk, and who'd rather the document looked like their business.
It sits alongside whatever you already run, rather than replacing it. If you have accounting software and a bookkeeper, this is still the fastest way to get a document out while you're on site, and everything exports to CSV to reconcile later.
The best time to send an invoice is while you're still parked outside.
