Mersal What Your Accountant Wishes You Tracked
The handoff is only as good as the record
Every month your accountant reconstructs your practice from fragments. A statement here, a bank line there, a payment someone remembers taking in cash. Most of the work is not accounting. It is archaeology. The accountant is not asking for more effort at month-end. They are asking that the effort already happened, at the moment each fact was true, and that it was written down as a record rather than left as a memory.
Four things account for most of the reconstruction. Consider them from the accountant's chair.
Per-line tax status and disbursements at cost
A single statement rarely carries a single tax treatment. Taxable services sit beside exempt items and beside disbursements that are pure pass-through: a filing fee, an expert's charge, a courier. If tax is applied at the level of the whole invoice, the accountant has to unpick it line by line to find what was genuinely taxable and what was merely advanced on the client's behalf. Rule the tax per line at the point of billing and the question never arises.
In Mersal, VAT is ruled per line, so one statement can mix taxable services, exempt items and disbursements without a second document.
Retainer drawdowns and rates frozen at issue
A retainer is client money until it is earned. The accountant needs to see the balance drawn down as work is delivered, not a lump sum booked as revenue on the day it arrived. On cross-currency matters the exchange rate matters just as much. If the rate floats, the same invoice is worth one figure in the ledger and another when it is paid, and the difference has to be explained. Freeze the rate at issue and the invoice means one thing forever.
Mersal supports retainer billing runs, and on multi-currency invoices the exchange rate freezes at issue.
Sequential serials and sealed receipts
Most tax regimes require invoice numbers to run in an unbroken sequence, so that a missing number is a question the practice must answer. Mixing proformas, which are not yet revenue, into the same run corrupts the sequence. Keep the books separate and each remains provable on its own.
- Three serial books. VAT, exempt and proforma each carry independent sequential serials. Proformas stay isolated from revenue until an authorized role converts them, one way.
- Receipts that cannot move. When a payment settles, a receipt is written with its own serial and sealed against edit or deletion for every role, administrators included. The payments ledger is append-only.
- Corrections on the record. Invoices freeze at issue. A correction is an auditable reissue; the original stays.
For the accountant, the reward is a one-click export to a spreadsheet, from records that already reconcile.
None of this asks the practice to work harder at the close. It asks the practice to capture each fact once, correctly, when it happens: the tax status of a line, the cost of a disbursement, the rate on the day, the serial on the receipt. Do that and the month-end handoff stops being an investigation and becomes a transfer. The accountant opens the export, ties it to the bank, and is done before lunch. What you track deliberately, you never have to reconstruct.
Matters, conflicts, VAT billing, sealed receipts and the docket, in one defensible system.
