Do I have to drop Nexus ERP to use CRMconnect?

No. CRMconnect works next to your existing system. Nexus ERP keeps accounting, production, payroll and SAF-T. CRMconnect takes over sales, orders, EDI and B2B portals.

Can CRMconnect connect to Nexus ERP?

Yes, through the API or scheduled file import/export, with Nexus master data mapping. The option and the flows are defined in the project.

What is the difference between an ERP and an operations platform?

The ERP is the system of record: accounting, production, tax reporting. The operations platform is where daily work happens: quotes, multi-channel orders, warehouse, EDI with retail chains and partner portals. Final documents end up in the ERP.

What happens to CRMconnect if we change our ERP?

CRMconnect keeps running sales, orders, warehouse, purchasing and portals. Connectors are reconfigured to the new ERP, while processes, users and operational history stay in CRMconnect; data mapping is done in the project. CRMconnect becomes a source of clean data for the new ERP, via API or export, while accounting history stays in the old ERP.

How long does implementation take?

CRMconnect starts from a few days; with full ERP integration it takes 4-6 weeks. Go-live is followed by a 15, 30 or 45-day hypercare period.

What happens to invoicing and e-Factura?

When you use them together, the project decides where the invoice is issued: in Nexus ERP, or in CRMconnect with the document then sent to Nexus ERP. What each CRMconnect package includes is on the pricing page.

Who can build the integrations with the ERP?

CRMconnect is an open platform, so you choose: your own team, an external team or partner, or the CRMconnect team. Every option uses the same public API, webhooks and MCP connector, with open documentation at docs.crmconnect.ro. No vendor lock-in.

Where do accounting and SAF-T stay if we use both?

In Nexus ERP. CRMconnect does not do SAF-T at the moment; it sends matched orders, deliveries, invoices and payments to the ERP. CRMconnect pricing is public on the pricing page, with a no-card trial.

How does CRMconnect connect to other systems?

Through a public REST API, webhooks and an MCP connector for ChatGPT and Claude, over EDI (AS2, EDIFACT) or through files. Custom modules can also be developed on the platform.

CRMconnect and Nexus ERP: the management suite and the operations platform

Short answer

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.

One-page summary for the board

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

Open
Partly open
Licensed
On request
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.Your own team.
2.An external team or partner.
3.The CRMconnect team.

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

How fast do I see results, and what risk do I take?

What matters to you

Time to value: CRMconnect starts from a few days; 4-6 weeks with full ERP integration.
Risk: you keep your ERP. Accounting, production, payroll and SAF-T stay in Nexus ERP, and CRMconnect is added on top of operations.
Independence: CRMconnect has a public API and supports custom modules, so you can connect other systems without depending on a single vendor.
If you change your ERP, operations keep running in CRMconnect: connectors move to the new ERP, while processes, users and operational history stay.
You choose who builds the integrations: your team, an external partner or the CRMconnect team, on the same public API. No vendor lock-in.

Together

Nexus ERP stays the company's system of record. CRMconnect becomes the place where teams sell, receive orders and work with partners. You can start with one module and expand as you grow.

Open API: connect whatever you need

CRMconnect has a public REST API, webhooks and an MCP connector. You or your integrator build freely on the platform and connect it to any system.

Public REST API with open documentation.
Webhooks that notify other systems when something changes in CRMconnect.
MCP connector for OpenAI (ChatGPT), Anthropic (Claude) and other AI assistants.
Zapier and Make for no-code automation.
Custom modules built on the platform.

See the API documentation CRM integration via API

Start with one module, not a project

Not every company needs EDI. Many customers start with the CRM, then add orders, purchasing, warehouse, projects or invoicing. You choose where to start.

Your ERP stays untouched.
You add modules when you need them.
Your data stays yours: a full export is available at any time, including through the API.

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

See all 65 modules

Agility, not just a promise

You start with a single module.
Implementation from a few days; 4-6 weeks with full ERP integration.
Custom modules on the platform.
Open API and MCP connector.
SFA app on Android and iOS.
The ERP can change without stopping operations.

Classic ERP model

General traits of the model, not about any specific vendor.

A company-wide implementation project.
Duration usually measured in months.
Adaptations are made through development.
Changing the system means a new migration project.

In short: when to choose each

When to choose Nexus ERP

You want a broad Romanian suite, with retail and HoReCa.
You need production, payroll and fleet in one system.
You want mobile SFA with on-the-spot payment collection.

When to choose CRMconnect

You want a public API, MCP connector and custom modules.
You want EDI from an EDI provider, integrated with orders and the portal.
You want a portal for distributors and for suppliers.
You want operations that do not depend on a single ERP.

When to use them 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.

Where we overlap

Nexus ERP has CRM, mobile SFA, WMS apps and a B2B portal. CRMconnect stands apart with a public API and MCP connector, module-by-module activation, being an EDI provider through EDIconnect, a supplier portal and independence from the ERP.

When we are, and are not, the right choice

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

You can change the ERP without stopping operations.

1. Operations do not stop
CRMconnect keeps running sales, orders, warehouse, purchasing and portals, without a pause.
2. 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.
3. 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.
