They record who, how much, what for. Out come, at the same instant, the double-entry posting, the trial balance, the income statement and the document the person is waiting for. Without knowing a single account number.
The account numbers are those of the Belgian chart of accounts (PCMN), exactly as the product posts them. The amounts are examples.
Every year, the same scene: the accountant asks for a trial balance and a general ledger, and the treasurer opens a spreadsheet with amounts, dates, and nothing that looks like accounting. Everything has to be rebuilt from memory. Here there is nothing to rebuild: every entry has already produced its posting.
A dues spreadsheet survives three months. After that nobody knows who is up to date, who paid ahead, or what should be chased. And chasing someone who has already paid costs more than not chasing at all.
This is what paralyses a volunteer: the fear of the wrong figure that can no longer be fixed. Most software offers only two ways out, quietly retouching or voiding everything. The first destroys the value of the ledger, the second makes it unreadable. We separate the two mistakes, because they have nothing in common.
Accounting software that promises everything is paid for in lost trust at the first audit. Here is the line, written in advance.
The first entry takes a minute, and it already produces its posting. No accounting setup to do: your country's chart is in place from the moment the church is created.
