Cadencebook

UK accounting firms serving clients under the digital income-tax cadence must review bookkeeping more often than an annual cleanup. Cadencebook compares authorized bank-feed events with bookkeeping records between quarterly updates and gives the firm a per-client evidence board. The supplied research confirms the April 2026 start but corrects the market premise: the first-phase threshold covers a smaller higher-income cohort, with broader thresholds arriving later. It also states that all four referenced API capabilities remain unverified, despite identifying relevant providers, so integration claims require proof before build. A bank-feed item is not accounting truth, and an unmatched or unusual transaction is a review candidate rather than an error, fraud or tax finding. Books can be incomplete for legitimate timing, cash, transfer, loan, personal-use or accrual reasons. A ready status means the firm's configured evidence checks are complete, not that a submission is accurate, accepted or compliant. Source transaction, proposed match, anomaly candidate, client query, accountant disposition, bookkeeping correction, client approval, filing command, authority acknowledgement, readback and tax outcome remain separate. Success is earlier resolution of supported discrepancies and less quarter-end rework—not automated accounting, universal client coverage or compliance certification.
