a3ERP and Sage Integrations

a3ERP and Sage: the same goal, different integrations

a3ERP, from Wolters Kluwer, and the Sage family are widespread among mid-sized Spanish companies, manufacturers and distributors, but they are not integrated in the same way. a3ERP is usually installed on the company's own servers or in a private cloud. In Sage, each product is a world of its own: Sage 50 is a more limited management solution, Sage 200 covers the full operation of a mid-sized company and Sage X3 is designed for groups with several companies and more complex manufacturing or logistics processes.

That is why we don't start from a generic connector. We identify the product, version, active modules and any customisations made by your ERP reseller, and use that to choose a connection route that is stable and can be maintained when the ERP is updated.

What flows between a3ERP or Sage and the online store

From the ERP to the eCommerce go items with their families and references, general and customer-specific price lists, discounts, available stock per warehouse and B2B customer data: payment method, delivery address, assigned sales rep and credit limit. Sales units matter too: boxes, packs or minimum multiples defined in the ERP that the store must respect so it doesn't accept orders the warehouse can't fulfil.

Towards the ERP go sales orders with their lines, shipping costs and taxes, and new customers once approved. In return, the store receives the order's progress to delivery note and invoice, so customers can check their history and download documents without calling the accounts team.

In distribution it is common for sales reps to keep taking orders by phone or on visits. The integration makes those orders, entered in the ERP, also appear in the customer's account on the store, so there is a single order history.

How to connect a3ERP or Sage installed on your servers

When a3ERP or Sage 200 sits on your network, the integration shouldn't open the database to the internet. We install a service on a server in your network that communicates outwards with the eCommerce platform or our integration layer, so no ERP ports need to be exposed. That service sends stock and price changes in short cycles, uploads orders as they arrive and leaves heavy catalogue and price list loads for the night, when fewer users are working in the ERP. If the connection to your server drops, orders wait on the platform until it is restored.

How we read from and write to the ERP depends on the product. Whenever the vendor offers an API or integration component, we use it, because it respects the ERP's logic when creating orders or customers. If none exists for what we need, we work with staging tables that the ERP itself processes or with file exchange, never writing directly to its main tables. Sage X3 exposes its own web services, which simplifies the connection in multi-company installations.

How we run an a3ERP or Sage integration

The reseller or partner who maintains your ERP is part of the project from day one. We agree with them which integration components need licensing or enabling, who creates the additional fields and how changes are tested.

We test on a test company or a copy of the database, with orders of every type your business handles: with shipping costs, with special discounts, from customers subject to equivalence surcharge or for export. Every synchronisation is logged, and failed ones are retried or reported to whoever needs to resolve them. At the end we document the flows, how often each one runs and what to do for each type of error, so your team and your reseller know how to act.

We integrate a3ERP and Sage with PrestaShop, Adobe Commerce (Magento), WooCommerce and Shopify, and with custom B2B portals for distribution networks.
