What we do with A3ERP

Data synchronization

Automatic sync of customers, suppliers, products, orders and invoices between A3ERP and your web apps, e-commerce or CRM.

Invoice automation

Automatic invoice generation in A3ERP from online store or CRM orders. Sequential numbering, tax calculation and automatic accounting entry.

Custom reporting

Data migration

Migration from A3ERP to other ERPs (Odoo, SAP, Holded) or to A3ERP from legacy systems. Data mapping, cleaning and validation.

Custom connectors

Connectors enabling A3ERP to communicate with modern REST APIs, payment gateways, e-commerce platforms and cloud tools.

Use cases

Real-world A3ERP integration scenarios

E-commerce + A3ERP

Every confirmed order automatically generates an invoice, updates stock and records payment. No manual intervention.

CRM + A3 Invoicing

When a deal closes in the CRM, a quote or invoice is automatically generated in A3ERP with customer data and product lines.

Unified management dashboard

Dashboards combining A3ERP financial data with CRM metrics and operational data for a complete executive view.

Migration to modern ERP

Complete historical data extraction, transformation to new ERP format and validated migration for companies needing to scale.

API

Does A3ERP have an API? How we connect it

A3ERP has no native REST API, but that does not stop us from integrating it.

Database access

Controlled reads and writes on the A3ERP SQL Server via ODBC, respecting referential integrity. The most direct route for near-real-time sync.

Exchange files

Import/export via the CSV and XML formats A3ERP supports natively. Ideal for bulk loads and periodic synchronization.

Custom REST API layer

We build a REST API on top of A3ERP so your web apps, e-commerce or CRM talk to A3 like a modern ERP: endpoints, auth and webhooks.

FAQ

Frequently asked questions about A3ERP

Does A3ERP have an API?
A3ERP does not have a native REST API. We integrate via SQL Server database access, CSV/XML exchange files and ODBC connectors. We can also create a custom REST API layer.
Can I migrate from A3ERP?
Yes. We extract historical data, transform it and migrate with validation and a parallel operation period.
Does the integration affect performance?
Minimal impact using optimized reads, caching and off-peak synchronization.
How much does it cost?
Basic integration 4,000-10,000 euros. Complete projects with multiple flows 15,000-35,000 euros.
Can you integrate A3ERP without my team developing anything?
Yes, that is exactly our service. We act as your external integration provider: we analyze your A3ERP setup, build the connector, maintain it and provide ongoing support. Your team needs no A3 expertise and no in-house developers on the project.
