ERP System.

Enterprise Resource Planning, the central business system that handles accounts, sales, purchasing, stock, and HR. Most SMBs use Sage, Xero, or similar. ERP is the commercial brain; MES is the production brain.

An ERP (Enterprise Resource Planning) system is the central business system that handles your commercial operations, accounts, sales, purchasing, stock, HR, often CRM. Most UK SMBs use Sage (50/200/Intacct), Xero, QuickBooks, NetSuite, or Microsoft Dynamics. Bigger operations might use SAP Business One.

ERP and MES are complementary, not overlapping. ERP handles the commercial side: customer orders, invoices, accounts, stock levels, supplier payments. MES handles the production side: where jobs are, what's being made, who's working on what. SMBs typically have ERP and bolt MES capability on later (or build bespoke MES that integrates with the ERP.

For AI integration, ERP is usually the destination) clean data extracted from documents (invoice matching), structured data captured from enquiries (CRM records), recommendations generated by AI (reorder lists). The ERP holds the source of truth; AI processes the inputs and writes results back.

Integration patterns vary by ERP. Modern cloud ERPs (Xero, NetSuite, Dynamics) have full APIs and integrate cleanly. Legacy on-prem (older Sage, custom systems) need more creative integration, file-based interfaces, email triggers, RPA where APIs don't exist. Almost always possible; the integration approach just shapes the build.

What this looks like in practice.

  • AI invoice matching writes extracted invoices back to Sage with cost codes and approval state.
  • AI document extraction populates new customer records in HubSpot from intake forms.
  • Stock forecasting AI generates draft reorders in NetSuite ready for buyer approval.
  • Bookings automation writes confirmed reservations to Xero with deposit handling.
