Building in public. Follow along on X

Free tool

The free project ledger, in Google Sheets.

Who paid what, who owes whom, who owns what. One tab, no signup. Make a copy and it's yours.

Opens Google Sheets and asks you to make a copy in your own Google Drive. We can't see your copy.

What's inside

Who owes whom

Set each person's share. The sheet works out who paid more and shows "Owes 11.00" or "Is owed 11.00".

Who owns what

Domain, GitHub, Vercel and more: owner, recovery email and backup admin. Missing a backup? It turns red.

Costs log

Add a row per bill: item, who paid, amount, monthly or yearly. Totals update on their own.

How to use it

  1. Click Make a copy in Google Sheets and save it to your Drive.
  2. Put your names and agreed shares in the yellow cells.
  3. List your project's assets and add a backup admin for each one.
  4. Add every cost at the bottom of the Costs block.
  5. Share your copy with your co-founder so you both see the same numbers.
