CRMconnect and Nexus ERP: board summary

Nexus ERP and CRMconnect complement each other. Nexus ERP is a Romanian suite with accounting, production, CRM, mobile SFA and a B2B portal. CRMconnect is the open operations platform, with a public API and MCP connector, an EDI provider through EDIconnect and a supplier portal, running with or without an ERP, including next to Nexus ERP.

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.

Licensed: paid API module from the vendor

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

REST API; writing from external applications is at extra cost, according to the vendor. Nexus API (nexuserp.ro)

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

  • Nexus ERP keeps accounting, production, payroll and SAF-T.
  • CRMconnect takes the flows you choose: EDI, portals, multi-channel orders, couriers.
  • The link runs through API or files, defined in the project.

When we are not the right choice

  • Production and payroll: they stay in Nexus ERP.
  • SAF-T: CRMconnect does not do SAF-T at the moment; it is done from Nexus ERP.
  • Retail POS and HoReCa: they stay in the Nexus suite.

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.
