Invoice Studio turns one Google Sheet into a working invoicing app.
Add a client, pull in the services you sell, and the invoice builds itself. Download it as a clean PDF — your business name, tax ID, itemised lines, tax and total due, laid out properly — or email it straight to your client with the PDF attached automatically.
The dashboard keeps the four numbers that matter in front of you: total invoiced, outstanding, overdue and paid. The invoice list lets you search by number or client, filter by Draft, Sent, Paid or Overdue, and change an invoice's status straight from the row.
Everything lives in a Google Sheet in your own Drive. There is an Open spreadsheet button in the sidebar whenever you want the raw data, and nothing ever leaves your Google account — there is no server on our side.
You pay once. It stays yours.
