Reconcile an Increase FBO pseudo-entity account against sub-tenant ledger balances

Steps

1. Set up a separate pseudo entity for the FBO account program, distinct from your corporate entity, that carries no Profit and Loss account and no equity, since P&L must pass through immediately to the underlying sub-tenant entities.
2. Identify independent data sources for bookkeeping versus reconciliation — generate your own sub-tenant debits/credits for bookkeeping, and reserve your bank statement strictly as the independent reconciliation source rather than a bookkeeping input.
3. Use Increase's Transactions and Balance endpoints as that independent reconciliation source, comparing them against your internally generated sub-tenant ledger on a recurring cadence.
4. Treat any mismatch between the aggregate sub-tenant ledger and the actual FBO account balance as a breakage requiring investigation — missing, additional, or mismatched transactions.
5. For flows that don't reconcile one-to-one (e.g., a batched sub-tenant transfer settled as a single bank entry), use one-to-many matching, and consider isolating messy flows into a separate account from cleanly reconciling ones.
