Rules that reach back

The rule you write in month eleven fixes month one.

A rule applies to every statement you’ve already loaded, and to your other clients too, so each decision you make on a backlog only has to be made once.

Overlapping statements caught

Clients send the same months twice all the time. Entrio flags the repeat instead of adding a second copy, which is how backlogs end up overstating turnover.

Transfers, not turnover

Money moving between the client’s own accounts is matched as a transfer. Across several accounts that’s often thousands of pounds that would otherwise look like sales.

Stop and pick up where you left off

Backlogs rarely get cleared in one sitting. The checklist shows where the job got to, so Thursday starts where Tuesday stopped.

Before and after

The same backlog, without the retyping.

The task
Traditional catch-up
The same job in Entrio
Getting the data in
Paste each month’s statement into a sheet, one tab at a time.
Import the whole range at once, in whatever chunks the bank exports.
Repeat payees
Recognised and coded again in every single month.
Coded once and applied to all of it, including months already loaded.
Duplicated periods
Found by eye, if at all, usually when the bank doesn’t reconcile.
Flagged on import, before they reach the ledger.
Inter-account transfers
Untangled manually across several accounts.
Matched as transfers, so they never touch turnover.
Knowing when you’re done
A judgement call, made when the file stops looking wrong.
The export stays blocked until the bank reconciles and debits equal credits.

FAQ

Catch-up questions.

How far back can I go?

As far as the client has statements. Each transaction lands in the accounting year its date belongs to, whichever file it came in. Reports cover one year at a time, so for a multi-year catch-up we suggest one statement file per financial year. Each year’s trial balance then stays clean on its own.

What if the client sends overlapping statements?

They usually do, and it’s how backlogs get double-counted. Entrio spots a transaction arriving twice and flags it instead of adding it again. It also matches transfers between the client’s own accounts, so moving money around doesn’t inflate turnover.

Do I have to categorise 1,500 transactions by hand?

No. Your rules file the whole history as it’s imported, and a new rule reapplies to everything already loaded. Code a payee once and every other occurrence follows, on this client and any other where it appears.

How does reconciliation work on a backlog?

Entrio checks the ledger against the statement balances, flags gaps and repeated date ranges, and blocks the export while a reconciliation is open. On a backlog, that check is usually what finds the missing month.
