Missing a vendor payment because it slipped through a pile of emails or paper bills can cost you a late fee or a damaged relationship. This ledger tracks every bill you owe, by vendor, with due dates and outstanding balances, so nothing gets paid late by accident.
Included in the $7/mo Tools Club · Works in Excel or Google Sheets · Includes a built-in AI prompt
Paying bills from a pile of emails or paper invoices works until volume grows past a handful of vendors — then something inevitably gets missed. A dedicated ledger gives you one place to see every vendor’s outstanding balance and due date at a glance.

Built-in AI prompt
Once you've filled this template in, it includes a ready-to-use prompt at the bottom of the sheet. Attach your saved file to ChatGPT, Claude, or any AI chat tool and paste it in — you'll get plain-English feedback on which upcoming bills to prioritize paying first given typical cash flow considerations, and which vendors have the largest outstanding balances, no accounting background required.
Logging bills only when you’re ready to pay them
Log every bill as soon as it arrives, even if payment is weeks away — this is what prevents a due date from being missed entirely.
Not tracking due dates alongside amounts
The amount alone doesn’t help you plan — due dates are what let you sequence payments around your cash position.
Missing early-payment discount terms
Some vendors offer a discount for paying early (like 2/10 net 30) — tracking terms here helps you decide when it’s worth taking advantage of that.
Losing track of recurring bills
Recurring vendor bills (software, rent, subscriptions) are easy to assume are "handled" — log them here too so nothing renews unnoticed at an unexpected cost.
