The quiet layer underneath
From scattered input to a dependable record.
Put in order
Tersum preserves originals, extracts structured facts and applies deterministic checks before anything moves forward.
Hand over cleanly
Your bookkeeper receives source-backed documents and context, while unclear cases remain visible for review.
Controlled by design
Autonomous where safe. Human where it matters.
Read broadly, write narrowly
Tersum gathers the evidence it needs while keeping consequential actions constrained.
Trace every decision
Originals, interpretations and approvals remain connected in an auditable record.
Keep the bookkeeper in charge
Tersum prepares administration. It does not replace the ledger, filings or professional sign-off.
