# Group finance guides

Short reads on intercompany reconciliation, Close Pilot, multi-ERP, organisational memory, FX close gaps, Dynamics 365 BC, audit trails, close ROI, spreadsheets, ledger import, ERP connectors, and REST integration.

- [Intercompany reconciliation: from GL to an auditable file](/en/guides/intercompany-reconciliation-explained.md) — What intercompany reconciliation means in consolidation, why it slows closes, and how group teams structure the work without losing audit evidence.
- [Close ROI: serious metrics for intercompany teams](/en/guides/group-close-roi-checklist.md) — How finance leadership can model payback on intercompany reconciliation with defensible metrics—hours, cycle time, audit drag—without software fantasy savings.
- [Beyond Excel: continuity for intercompany work](/en/guides/interco-beyond-spreadsheets.md) — Why multi-ERP portfolios graduate from Excel to a governed workspace: continuity across closes, reviewer evidence and APIs for automation without a monolithic ERP programme.
- [Intercompany FX at close: policy owners and explainable residuals](/en/guides/intercompany-fx-close-gaps.md) — Why FX residuals on intragroup balances need treasury policy sign-off—and how group finance documents explainable breaks without pretending software sets rates.
- [Business Central: from OAuth to intercompany reconciliation sessions](/en/guides/dynamics-365-bc-intercompany.md) — Connect BC companies to Ninon, map entity GUIDs, and run intercompany matching on general-ledger lines without replacing your Microsoft stack.
- [Audit trail: evidence on intercompany reconciliation decisions](/en/guides/intercompany-reconciliation-audit-trail.md) — What auditors and internal control expect from intercompany matching: proposal evidence, reviewer decisions, and continuity across closes—not inbox threads.
- [Close Pilot: prove intercompany reconciliation on a real period](/en/guides/close-pilot-intercompany.md) — How to frame a Ninon Close Pilot in 2–3 weeks: ledger CSV, session, review, audit pack and success criteria before an annual Workspace.
- [Multi-ERP: one intercompany pack despite heterogeneous systems](/en/guides/multi-erp-intercompany-reconciliation.md) — Multi-ERP groups: normalise ledger exports, start with CSV, then connect BC, NetSuite, SAP or Intacct without replacing consolidation.
- [Organisational memory: do not restart from zero each close](/en/guides/organisational-memory-group-close.md) — Reuse reconciliation patterns and decisions from one close to the next: fewer re-litigated intercompany breaks in group finance.
- [REST integration: trigger matching from your systems](/en/guides/rest-api-integration.md) — Authentication, how to trigger a run, and HTTP response modes (queued vs in-process) for IT and integration partners.
- [Feed the general ledger: ERP export, columns, and API call](/en/guides/ingest-ledger-csv-api.md) — Business scope, exact column headers, entity resolution, text and multipart ledger import (.csv/.xlsx), JSON counters and per-line errors.
- [NetSuite and Xero connectors: register tokens via API](/en/guides/erp-oauth-netsuite-xero-api.md) — Operational reference for NetSuite and Xero token registration, admin role, and post-connect sync behaviour.
- [ERP connector operations and erpLinks mapping](/en/guides/erp-connectors-runbook.md) — Operational reference: per-connector entity mapping keys, Xero tenant selection, NetSuite browser or scripted OAuth, SAP B1/S/4 variants and Intacct location pagination.
