Expenses in.Net worth out.
A spreadsheet drifts because every month you re-type five totals that could have been computed. Ledger stores the detail and derives the rest — so the summary and the detail cannot disagree.

// why
The total was the problem.
In a workbook, the monthly summary is a figure someone maintains by hand. It is correct until the month you add an account and forget to widen a formula — and nothing tells you, because a spreadsheet cannot know what its own total was supposed to be.
Here it is a view over the rows. There is no stored total anywhere in the database, so there is nothing to fall out of step.
// how it works
Three things, in the order you will do them.
step 1
Bring the workbook in
Import reads your expense sheets and your cash, investments, receivables and credits tabs — then checks itself against the totals your own history sheet already carried, month by month, before writing anything.
- Expensesone sheet per month
- Casha column per month
- Investmentsa column per month
- Receivablesone line per loan
- Creditsone line per card or loan
step 2
Log the way you talk
“grab 336, moveit 121” becomes two rows with the right categories. Merchants you have used before resolve instantly with no AI call at all; only genuinely new ones ask the model, and nothing saves until you have checked it.
step 3
Fill in what changed
Opening a new month copies last month’s balances forward, so you only type the numbers that actually moved. Net worth, the month-on-month change and every category total follow from there.
// what it does
Built to be checked, not believed.
// get started
Start with the month you are in.
Your nine expense categories are created for you at sign-up, so you can log something in the first minute — and import the back catalogue whenever you feel like it.
