ERP webshop module vs a dedicated B2B e-commerce platform: what's the difference?

Manufacturers and wholesalers already running SAP, Business Central, Odoo or another ERP eventually face the same question: does the webshop module that comes with that ERP suffice, or is a separate platform needed? Both options connect to the same data source, but differ sharply in what the customer sees online and how fast new functionality lands.

What an ERP webshop module actually offers

An ERP webshop module, such as Odoo's or a comparable suite's, reads products, prices and stock directly from the ERP and displays them through a simple web interface. The big advantage: no separate integration needed, no sync delay, one system to manage.

For a business with a straightforward catalog, a limited number of customers and little commercial complexity, that covers a large part of the need. The module does what it promises: showing products and sending orders through to the ERP.

Where an ERP webshop module runs into limits

Customer experience and ease of use. ERP systems support business processes; building an appealing online shopping experience usually isn't part of that. Search, filters, product presentation and mobile display tend to stay basic, while business buyers keep getting used to the ease of use of consumer platforms.

Product information and media. An ERP tracks item numbers, prices and stock, but lends itself less well to rich product information: technical spec sheets, multilingual descriptions, photos, certificates. Without a separate PIM or DAM system, the product page stays limited to what the ERP registers by default.

Customer-specific catalogs and commercial logic. Packaging units, tiered pricing, minimum order quantities, customer-specific assortments: that kind of logic often sits scattered across configuration fields in an ERP that were never meant to be shown to an end customer. A webshop module inherits that limitation.

Self-service beyond the core processes. Requesting quotes, viewing invoices, searching order history: features that go beyond showing products and placing orders require extra development on top of the standard module.

Development pace. New functionality for an ERP webshop module goes through the same development process as the rest of the ERP: releases, test cycles, often with an implementation partner billing per change. That pace usually runs slower than a platform built exclusively for online sales.

What a dedicated B2B e-commerce platform offers instead

A platform such as Fonda is built for exactly what an ERP webshop module leaves out: a shopping experience tailored to business buyers, with customer-specific pricing and catalogs, PIM and DAM for product information, a self-service portal for invoices and quotes, and packaging logic that becomes visible and orderable for the customer. The ERP integration stays in place: standard connectors with SAP, Business Central, AFAS and Exact sync pricing, stock and customer data in real time, while the ERP remains the source of truth for administration and accounting.

The ERP itself doesn't change. A layer gets added on top that's built specifically for the customer experience, while the ERP keeps doing what it was built for: supporting business processes.

How to work out what fits your situation

A few questions point the way quickly. How many customers order online, and how much do their pricing agreements differ? How important is product information, technical spec sheets and imagery to the purchase decision? Do customers expect a self-service portal for invoices and quotes, separate from the ordering function? How often does the commercial logic change, and how fast does that change need to show up online?

The more often the answer points to complexity and expectations that go beyond a product list with an order button, the greater the chance a dedicated platform pays off more than the ERP's webshop module.

Frequently asked questions

Can I replace my ERP webshop module with a separate platform later without changing my ERP?

Yes. A dedicated B2B platform connects through standard connectors to the existing ERP and replaces only the customer-facing layer, not the ERP itself. Pricing, stock and customer data keep coming from the same system.

Is an ERP webshop module cheaper than a separate e-commerce platform?

The license cost often looks lower because no separate integration is needed, but missing functionality, such as PIM, DAM or a self-service portal, still requires extra development. That cost factors into the total comparison.

Does a dedicated platform work alongside Odoo?

Yes, provided the platform offers a standard connector for Odoo or a comparable ERP. That way, the ERP stays the source for administration while the platform handles the customer experience.

When is an ERP webshop module enough on its own?

With a straightforward product catalog, few customer-specific pricing agreements and limited need for self-service, an ERP webshop module covers the basic need without an extra platform.

What does it cost to switch from an ERP webshop module to a dedicated platform?

That depends on the complexity of the existing product data and the ERP integration. With standard connectors and structured onboarding, a platform like Fonda typically goes live within a month.
