Pilot scope
Agree the finish line before the work starts.
This is the proposed shape for one controlled export review. The accounting practice supplies agreed bank and ledger CSV exports; Litt Horizon returns calculated controls and exceptions, not posted bookkeeping or professional conclusions.
Proposed starting scope
1 current month · up to 100 bank rows · 1 bank account
£69 fixed when every fit condition is met. No recurring commitment.
Included
Defined production work
- Bank arithmetic checkCompare opening balance, supplied bank-row movement and reported closing balance.
- Bank-to-ledger differenceCompare the supplied bank closing balance with the bank-account movement in the ledger export.
- Reference matchingAggregate supplied bank and bank-ledger rows by reference and list differences.
- Exact-duplicate flagsIdentify identical ledger rows for investigation; no row is automatically removed.
- Reviewer control packReturn the population, calculated results, exception register and explicit limitations.
