Does this sound familiar?

Without the Solver

  • Spending 45 minutes on YouTube trying to remember if “unearned revenue” is a debit or credit
  • Accidentally entering the wrong account and not catching it until your books don’t balance
  • Paying your accountant to fix a mess of errors at year-end — when you could have gotten it right the first time
  • Freezing every time a loan payment has both principal and interest to split out
Recommended

With the Solver

  • Pick your transaction in plain English — no accounting jargon required
  • The correct debit and credit appear instantly — with an explanation of why it works
  • A built-in balance checker turns green only when everything is correct — you can’t copy a wrong entry

Everything you need to know

Nope. The Solver works in Microsoft Excel (any version) and also in Google Sheets, which is completely free. If you have a Google account, you’re ready to go.
It’s your safety net. If you haven’t filled in all the required fields, or if something looks off, the status cell shows “Review Needed” so you know not to copy that entry into your books yet. It only turns green when everything is correct and balanced.
When you choose a transaction type from the dropdown, the Solver cross-references a built-in library of 25+ scenarios against a pre-loaded Chart of Accounts. It then auto-fills the correct debit and credit accounts — and shows you a plain-English explanation of why that entry works.
Yes. The Account 1 and Account 2 fields are editable, so you can type in the exact account names you use in your accounting system. The Solver gives you a smart suggestion, but you’re always in control.
No, and we’re upfront about that. The Solver helps you create correct, structured journal entries for common transactions. It doesn’t replace professional judgment for complex situations, tax strategy, or auditing. Think of it as a very smart reference guide that also does the formatting for you.
You get instant access to the Excel/Google Sheets file via Gumroad, plus the step-by-step walkthrough video. All future updates are included at no extra charge — your download link always stays current.

One small investment. Cleaner books forever.
