Intercompany balance-sheet reconciliation for multi-entity Xero/QuickBooks groups. Here's exactly where Balancer and Postlock overlap - and where they don't.
AR/AP matching between related entities, automated cross-entity recharges and bank reconciliation - genuinely useful if you run a multi-entity group and need the entities to tie to each other.
Balancer reconciles entities against each other. It doesn't snapshot a signed-off period and watch it for changes afterwards - that's a different problem, and the one Postlock solves.

Post-lock monitoring: we haven't found another tool that watches closed periods and names the document and person behind a change - check us on it in the table below. The Excel pack: the tools we've compared keep reconciliations in their own dashboards; Postlock exports a real file because auditors and accountants live in files, not dashboards.
If you need multi-entity consolidation, driver-based forecasting, deep workflow, or client data-hygiene monitoring, look at ScaleXP, Numeric or Dext - they go further in those specific areas. Postlock is deliberate and narrow.
We request only read-only Xero access - technically incapable of changing your ledger. If Postlock were ever compromised, an attacker could see but never touch your numbers. That's a trust decision we won't trade away.
Every check here is deterministic and re-performable - the same inputs give the same answer, which is what audit evidence requires. Your ledger is never read by a model, and there's no metered AI cost under the price. If a tool's pitch leans on AI reading your transactions, ask two questions: what does it find that a written rule couldn't, and what happens to their costs when model pricing moves.
