A Repeatable API for Every Audit Client

If your firm serves more than a handful of clients, you already know the real cost of an audit engagement often begins with data-access work before the accounting work can start. Client A is on QuickBooks Desktop with an export-to-CSV workflow. Client B is on a custom-built internal tool with a database someone on their team has to run a one-off SQL query against. Client C’s “export” is a screenshot of a report, emailed. Every engagement starts by re-solving the same problem: how do we get the data out, in a shape we can actually work with.

That data plumbing can consume billable time before review begins.

One API shape makes the work repeatable

Every LedgerWriter tenant uses the same resource and report shapes: the same journal-entries endpoint, the same account-balances and trial-balance projections, and the same chart-of-accounts resource. A query built against one client’s LedgerWriter tenant uses the same resource shape for another client’s tenant. Build the trial-balance pull once. Build the journal-entry-history pull once. Point each request at the client’s tenant with that client’s API token.

Give reviewers access suited to their work

LedgerWriter enforces roles at the command layer. An auditor can be given access to query reports while the client keeps posting, approval, and reversal authority separate.

Make evidence gathering the repeatable part

The review, judgment, and sign-off remain the work of the audit firm. A consistent API can make evidence gathering repeatable across clients.
