Keep your Sage.
Replace the spreadsheets running production.

Sage 50, 200 and X3 are reliable accounting platforms. They are not built for batch traceability, mock-recall workflows, or retailer-specific dispatch templates — and they should not be. Keystone is the production layer that sits next to Sage and feeds clean invoiced sales back. No Sage replacement. No ERP migration. No Mary-in-accounts learning a new ledger.

• Compatible with Sage 50, Sage 200 and Sage X3 — Intacct on roadmap
• Invoiced sales publish from Keystone → Sage on dispatch — no double entry
• Your finance team keeps using Sage exactly as they do today
• BRCGS-grade traceability and audit trail Sage was never designed to give you

Finance in Sage. Production in Keystone.

Most small and mid-sized food manufacturers do not need a full ERP replacement project. They need a reliable accounting package — which Sage already is — connected to a production and operations layer that actually matches how the factory works. That is the entire pitch. Sage stays where it is. Keystone takes over the operational reality: orders, planner, batches, QC, dispatch notes, COAs, pallet labels, customer codes, full traceability.

You have already felt this.

If you have spent more than a year trying to make Sage handle batch numbers, you know the pattern: custom fields, third-party traceability add-ons, exports to Excel that get re-imported, audit-log gaps the BRCGS auditor noticed. None of that is a Sage fault — it is a category mismatch. Sage was built to keep the ledger correct. Keystone was built to keep production reality correct.

One direction by default. Clean. Auditable.

Not anti-ERP. Pragmatic-ERP.

A large multi-site producer with plant automation, MES, advanced costing and EDI may genuinely need a full ERP or a Sage X3 + bolt-on stack. For them, Keystone may sit below ERP as a specialist operational layer or serve a single site. For most artisan, family-owned and mid-market producers — the kind already using Sage 50 or 200 — running Sage + Keystone side by side is faster, cheaper and lower-risk than any ERP migration.
