Receipts that need a decision

Everything Claude could not place on its own. One click each: business or private. Photo receipts show the picture. Your answers are saved here and Claude reads them back next time.

Sales and money owed to you

Work you have sold and billed but not been paid for. Each one is added to the cash chart in the month you expect the money. Overdue ones count in the current month, so chase them. Anything more than 60 days late is left out of the forecast until it is paid. Press Received when the money lands and it moves into Bank today for you.

Your data

Checking where this page can save.

Import from Claude

Claude gives you a file called business-runway-import.json. Pick it here, or paste its text. You see what is in it before anything is saved.

Back up and update

Download a backup now and then. When you ask Claude to update your runway outside Cowork, give it the short version first, so it knows what is already here.

Settings

Claude fills these during setup. You can change them here any time. Rates are yours to check: this page does not know your local tax rules, so ask your accountant.
