Subledger

The subledger your GL needs.

Every close leans on registers that live in spreadsheets, because nothing else bends to their shape – the portfolio that needs marking, the contingencies that need watching, the confirmations that need chasing. Assertion's Subledger keeps that flexibility and adds what a spreadsheet never had: typed columns, review with sign-off, sealed period snapshots, an audit trail behind every number.

Whatever shape the close demands.

Assertion's Subledger holds any shape. Every one carries the same controls – review with sign-off, sealed period snapshots, an audit trail.

  • Investment roll-forwardpositions marked each quarter; beginning plus movements equals ending
  • Quarterly evaluationsthe workpaper behind each position: basis, impairment review, support
  • Audit confirmationswhat was requested, what came back, what is still outstanding
  • Legal contingenciesmatters and exposures, assessed and re-assessed each period
  • Warrant & option registerinstruments with strikes, expiries, and valuations to keep current

Proposed from the document, cited to the sentence.

Hand it whatever carries the record – a memo, a statement, a scan – and let Assertion propose updates to the Subledger for you. All with traceability in mind.

Turn your tracker into a live roll-forward.

Create the records – additions, disposals, revaluations – and Assertion's Subledger builds from there. Periods seal as snapshots, so beginning balances carry instead of being re-entered.

A detailed record, not a separate tab.

Where a row needs its story told – the basis, the procedures performed, the support – it lives as one governed record in a queryable table, not a workbook with a tab per name. Plus, customizable automation that suits your needs.

Governed like a system of record.

Role-based access controls down to the column, and every action lands in an append-only audit trail.
