Three questions the ledger should answer.
Which invoice is this money for?
A 500 receipt on two open 1 000s is not a balance problem — it is a case problem.
Who is past due, and by how much?
Aging lived in a pivot. Reminders lived in the inbox. Neither matched the books.
Is the GL still true?
AR sheet, bank CSV, and the “real” file diverged every month-end.
One journal. Cases you can explain.
Double-entry that stays balanced
Journal is the source of truth. Balances walk the books — not a parallel sheet.
Open items, not faceless balances
Every invoice is a case. Payments allocate to cases — FIFO suggested, always overridable.
Dunning that books itself
Levels, fees and interest live on the case. The next reminder capitalises cleanly.
Chart of accounts that fits the work
Legal class ranges stay fixed. Inside them — free accounts, including one debtor per unit.
Open items that read like a story.
A 500 receipt sits on the first 1 000 instalment if you say so — never on a faceless 2 000 balance. Fees and interest stay on the case.

Journal first
Every receipt and fee posts once. Sub-ledgers match; the GL never invents a second truth.
Allocation, not dump
Unallocated cash is visible. You put money on invoices — the system does not guess a lump balance.
Built for property, open for business
Per-unit debtor accounts make a building’s AR a set of cases. Trade clients work the same way.
Whose books are these?
Your company or building
One mandate, clean open items, reminders that match the ledger — not a second spreadsheet.
- Fiscal year, CoA and dunning you control
- Receivables you can explain to an owner or a client
Practice or management firm
Invoices, allocations and dunning as product work — each client (or building) stays its own case file.
- Parties, products and income accounts mapped once
- Aging and next-reminder queues across the portfolio
Start with the journal. Cases follow.
Open the books — chart of accounts, open items and dunning have a place that stays true.
