Affinity, Carta, and the ledger
A reference architecture for keeping investment records reconciled continuously — not once a quarter under deadline.

Three systems, three jobs
Affinity holds relationships and deal context. Carta holds positions and cap table truth for many funds. The ledger holds accounting reality.
Problems start when any one of them is treated as the only source of truth — or when reconciliation is postponed until LP week.
A practical control model
Define which fields are authoritative in each system. Deal stage lives in Affinity. Position amounts live in Carta. Booked entries live in the GL.
Run a cadence reconciliation with an exception queue — not a heroic workbook every ninety days.
Feed approved outputs into LP packs and dashboards only after exceptions clear.
Where automation helps
Automate matching and variance flags. Keep humans on judgment and exception resolution.
Document owners and cutoffs so the process survives staff turnover and audit questions.
