Not another record-keeping app
A record-keeping app
You type. It stores. When a company quietly dies or reprices, it still shows what you typed.
Tero
Connected to the register. When the official record changes, Tero notifies you. Nothing to remember, little to upload.
And your accountant? They file the claim. Tero makes sure there's nothing they weren't told about.
