E‑commerce ERP, PIM and WMS integration that stays in sync

We connect your store with ERP, PIM, WMS, payment and shipping systems so stock, prices and orders match without retyping, and sync errors surface before a customer notices them.

20 minutes online. You get a straight answer: buy, build or drop it.

When you need an integration

Two glass blocks joined by a bridge that has broken in the middle. The two halves no longer line up, and glass cubes that fell from it lie under the gap.
Today There is a gap between the store and the ERP, and stock, prices and orders fall into it.
  • Stock levels do not match

    A customer buys a product that is already gone, or the store shows it as sold out while it sits in the warehouse.

  • Orders are retyped by hand

    Your team copies orders from the store into the ERP, and statuses back to the customer.

  • Price lists live in the ERP

    B2B prices and discounts sit in the accounting system, and the store keeps its own outdated copy.

  • Product data in several places

    Descriptions, attributes and images live in the PIM, spreadsheets and the store at the same time.

What you get

  1. A data flow map

    Which data, in which direction, how often and which system is its source.

  2. Integration via API or middleware

    Direct, through middleware or a connector tool, depending on the systems and volume.

  3. Sync of the key data

    Products, prices, stock, orders, statuses and documents, following the map.

  4. Error handling and monitoring

    Queues, retries, logs and alerts for your team.

  5. Tests and documentation

    Tests on test data and documentation that lets you maintain the integration without us too.

How we design an integration

An integration lasts for years only when it is clear from day one who owns the data and what happens when something goes wrong.

  • A source of truth for every data type

    We decide which system owns products, prices, stock, customers and orders. Without that, every sync eventually drifts.

  • Sync mode that fits the data

    Not everything has to be real time. Stock and orders usually are, while the catalogue is often synced in batches.

  • Error handling

    Queues, retries and operations that are safe to repeat: a short ERP outage neither loses an order nor creates a duplicate.

  • Monitoring

    You can see what synced and what did not, and you get an alert before an error reaches a customer.

How we work

  1. Conversation

    Which systems, which data and where the manual steps are today.

  2. Data map and fixed price

    We design the flows and quote the integration at a fixed price.

  3. Build on test data

    The integration runs first in a test environment with your real data structure.

  4. Go-live

    Cutover, close watch over the first days and adjustments.

  5. Maintenance

    Updates when the ERP or store changes, and extension to further systems.

Systems

Examples of systems a store is commonly connected to: SAP Business One, Microsoft Dynamics, NetSuite, Comarch ERP, Akeneo, Pimcore, WMS platforms, and payment and shipping providers. Not a closed list: what matters is an available API or a way to exchange data.

Questions about e-commerce integrations

What is ecommerce ERP integration?

It connects your store and ERP so both work on the same data: stock and prices stay current, orders reach the ERP automatically, and statuses and documents flow back to the customer. Manual retyping and the errors that come with it disappear.

Which systems should be integrated with a store?

Most often the ERP (stock, prices, orders, documents), a PIM (product data), a WMS (warehouse and shipping) and payment and shipping providers. We start with the flow that costs your team the most manual work.

Ready-made connector or a custom integration?

A connector is enough when it handles your data and process without workarounds. A custom integration makes sense with non-standard pricing, several warehouses, B2B or high volume, where connectors start losing data.

We run PrestaShop with our ERP and the sync keeps breaking. What now?

First we find which field drifts: the tax rate, the order currency, the payment status or the stock level. Most failures we see on ERP and PrestaShop forums come from field mapping in the connector, not from the platform itself. If the connector can be fixed with configuration, we say so. If the integration is the only reason to stay on an old PrestaShop version, we design the ERP-to-store flow from scratch, and the platform stops being the constraint.

How much does ERP integration cost?

We quote the integration at a fixed price once the data is mapped, so you know the cost before work begins. The price depends on the number of systems, the quality of their APIs and the number of data flows.

How do you keep stock levels in sync?

One system, usually the ERP or WMS, should own stock. We send changes as close to real time as possible, and the store also reserves stock at checkout so two purchases never land on the same last item.

What if every company in the group has its own ERP?

We connect each system separately, and the store knows which ERP is the source of stock, prices and documents for a given product. When customers should buy from several companies in one cart, it becomes a marketplace platform, which we describe on its own page.

Do you only build integrations for Medusa stores?

We build integrations as part of Medusa implementations and migrations, where they become part of the store’s logic rather than a separate plugin. If your store runs on another platform, we will work out in the first conversation whether an integration makes sense without migrating.
