CRMconnect and SAP Business One: board summary

SAP Business One and CRMconnect complement each other. SAP Business One is SAP's ERP for SMEs, with finance, CRM, purchasing, inventory and a mobile sales app, sold through partners. CRMconnect is the operations platform, connected through the Service Layer, adding a portal for distributors and suppliers, EDI as a provider, WMS, couriers and e-Factura straight from the order.

How open the ERP is to integrations

The CRMconnect side is the same everywhere: connector, open API, implementation in days or weeks. The difference comes from how the ERP opens up its data.

Enterprise: fully documented API, licences and partners; high but predictable cost

  1. Open
  2. Partly open
  3. Licensed
  4. On request
  5. Enterprise

Fully documented API (Service Layer, REST/OData); SAP licences and partners. CRMconnect has numerous implementations alongside SAP.

High but predictable cost.

Criteria: whether the API is public and documented, whether it is included or licensed separately, whether access is developed on request. The level does not describe the vendor's exact prices.

Open platform: you choose who builds the integration

CRMconnect is an open platform. You choose who builds the integrations:

  1. 1.Your own team.
  2. 2.An external team or partner.
  3. 3.The CRMconnect team.

Every option uses the same public API, webhooks and MCP connector, with open documentation. No vendor lock-in.

How they work together

  • SAP Business One keeps accounting and finance.
  • CRMconnect takes the portal, EDI, warehouse, couriers and multi-channel orders.
  • CRMconnect has numerous implementations alongside SAP; the link runs through the Service Layer, DI API or an integrator, defined in the project.

When we are not the right choice

  • Accounting and finance: they stay in SAP Business One.
  • SAF-T: CRMconnect does not do SAF-T at the moment; it is done from the accounting ERP.
  • Production: it stays in the ERP.

When we are

  • You want connected commercial and logistics operations: sales, orders, purchasing, stock, warehouse, couriers and invoicing.
  • You work with or without an ERP.

When you change your ERP

  • Operations do not stop: CRMconnect keeps running sales, orders, warehouse, purchasing and portals, without a pause.
  • Links move to the new ERP: Connectors are reconfigured: the old endpoints become the new ones. Processes, users and operational history stay in CRMconnect. Data mapping is done in the project.
  • Clean data for the new ERP: CRMconnect becomes a source of clean data for the new ERP: customers, products and PIM, prices, suppliers, commercial documents and operational history, via API or export. Accounting history stays in the old ERP.

The first 30 days and beyond: a typical path

  1. Day 1: Users and the first module, for example the CRM and the sales pipeline.
  2. Weeks 1-2: A second module, as needed: orders, portal or purchasing.
  3. Weeks 4-6: Full integration with the ERP.

A pilot on a single flow usually takes 2-4 weeks.
