Magento System Integrators: ERP, CRM and PIM Integration Services

A Magento system integrator connects a Magento store to the other systems a business runs on: ERP, CRM, PIM, payments, shipping, marketplaces and marketing tools, so that products, prices, stock, customers and orders move between them without manual work. This guide explains which integrations a Magento store usually needs, how they work, what to do when your ERP has no API, and how to choose an integration partner. If you already know what needs connecting, see our Magento integration services.

What does a Magento system integrator do?

Most growing stores end up with the same problem: data lives in several systems and people copy it by hand. Prices are updated in the ERP and again in Magento, orders are re-typed into accounting, stock is out of date on marketplaces.

A system integrator:

maps which data lives where, and which system is the source of truth for each field;
connects the systems through their APIs, or through files where there is no API;
builds the sync: what moves, in which direction, how often, and what happens when something fails;
monitors the integration after launch, because APIs and business rules change.

Common Magento integrations

ERP

The ERP is usually the source of truth for products, prices, stock and customers, and it receives orders from Magento. Typical ERPs we connect: SAP Business One, Microsoft Dynamics 365 and Oracle NetSuite.

What usually moves:

products, prices and customer-specific price lists, from the ERP to Magento;
stock levels, from the ERP to Magento, often every few minutes;
orders, from Magento to the ERP;
invoices, shipments and order statuses, back to Magento.

Other ERPs: SYSPRO, Sage, Epicor, Odoo

Manufacturers and distributors often run a mid-market ERP such as SYSPRO, Sage, Epicor or Odoo. The integration follows the same pattern as with SAP or Dynamics: decide which system owns products, prices, stock and customers, then connect Magento through whatever the ERP offers: an API, a business-object layer, a database view or scheduled file exports. SYSPRO is covered in more detail below.

CRM

A CRM such as Salesforce, HubSpot or KeyCRM gets customers, orders and sometimes quotes, so the sales team sees the full history without opening Magento.

PIM

A PIM such as Akeneo or Pimcore holds product content: descriptions, attributes, images and translations. Magento receives it, so editors work in one place and every channel shows the same data.

Marketplaces and product feeds

Amazon and Google Shopping (Google Merchant Center feeds) need products, prices and stock from Magento, and marketplace orders need to come back. The main risk is overselling, so stock sync speed matters.

Email marketing and automation

Email platforms such as Klaviyo, Mailchimp and Dotdigital (formerly dotmailer) get customers, orders, products and abandoned carts from Magento, and use them for automated emails: welcome series, cart reminders, post-purchase and win-back campaigns. Each has a Magento extension that covers the basics.

Integration work starts when the data you need isn't in Magento alone:

ERP data in email segments. Customer type, contract terms or purchase history from SAP Business One, Microsoft Dynamics 365 or Oracle NetSuite, sent to Klaviyo, Mailchimp or Dotdigital, so campaigns reach the right accounts.
B2B accounts with several buyers under one company.
Marketing consent that has to stay the same in the store, the CRM and the email platform.

For an example of an automated flow, see how to create a multi-channel abandoned cart workflow with SMS and email.

Payments and shipping

Payment providers and shipping carriers usually have ready-made Magento extensions. Integration work starts when the extension doesn't cover your logic: special payment terms for B2B customers, or a carrier without a module.

Spreadsheets and custom APIs

Not every system has a modern API. Smaller suppliers often send price lists in Excel or Google Sheets, and in-house systems may have their own custom API. These can be integrated too, with validation, so a broken file doesn't break the store.

ERP integration without an API: files, XML and FTP

Many ERPs that manufacturers and wholesalers rely on are old, heavily customized, or simply not allowed to change. That doesn't block an integration. The data can move as files, as long as the files are validated and the transfer is monitored.

Two of our projects worked exactly this way:

A B2B self-service portal on Magento 2 for an industrial equipment manufacturer. The legacy ERP had no API and could not be modified. Products, customer prices and stock arrive as XML over FTP, with validators and alerts on the FTP side; orders and customers go back through extended Magento APIs. The portal serves 24,000+ B2B customers, and the ERP was not changed. Read the case study.
Headless B2B commerce on Magento 2 inside an existing TYPO3 website, for the US division of a German manufacturer. The ERP and PIM only exchange files: about 5,000 SKUs are synced daily and stock every 30 minutes, via XML over FTP. Read the case study.

What makes a file-based integration reliable:

Validation before import. A file with missing columns or broken prices is rejected and reported, not loaded into the store.
Monitoring of the transfer. If the ERP stops sending files, someone gets an alert before stock on the site goes stale.
Idempotent imports. Re-running the same file doesn't create duplicate products or orders.
A clear owner for each field. The ERP owns prices and stock, Magento owns content and the checkout, and nothing is edited in both places.

Magento and SYSPRO integration

Who runs SYSPRO

SYSPRO is an ERP built for discrete manufacturers and distributors: industrial equipment, electronics, metal fabrication, automotive and aerospace parts, food and beverage, chemicals, medical devices. A typical SYSPRO company has somewhere between 50 and 500 employees and sells B2B: to dealers, distributors, contractors and trade accounts, often with a spare-parts or B2C store on the side.

The situation we see at companies like this is familiar. SYSPRO holds everything that matters for selling: customer-specific price lists and contract prices, stock across several warehouses, credit limits, ship-to addresses. The website is a catalog. Customers find the product online, then send an email or call, and someone keys the order into SYSPRO by hand. A Magento store connected to SYSPRO lets those customers see their own prices and stock and order themselves, while SYSPRO stays the system of record.

How SYSPRO exposes its data

e.net Solutions business objects are SYSPRO's official API to its business logic: queries (customers, prices, stock) and transactions (for example, creating a sales order). They are licensed per functional area, so the first check is which e.net licenses the SYSPRO site already has.
In SYSPRO 8, the business objects are reachable through the SYSPRO WCF service, with REST and SOAP endpoints.
SYSPRO doesn't push changes to other systems, so the integration has to ask for them: scheduled queries for stock and prices, or scheduled exports where the API isn't licensed.

Ready-made connector or custom integration?

There are third-party SYSPRO connectors for Magento and Adobe Commerce, for example Commercient on the Adobe Commerce Marketplace, Codeless Platforms, iPaaS.com and Room 40. A connector is a good start when the data flows are standard: products, stock, customers and orders.

Custom work is usually needed on top of it, or instead of it, when the business rules are where the value is:

contract and customer-specific pricing that has to match SYSPRO exactly, including quantity breaks;
stock from several warehouses, with rules for which warehouse ships which order;
B2B company accounts with several buyers, approval limits and credit holds;
quote requests for large or configured orders;
spare parts that must be ordered by serial number or machine model.

Example: a SYSPRO distributor's B2B store on Magento

Here is how we would design the integration for a distributor with 5,000 SKUs, two warehouses and a few hundred trade accounts:

Customers and ship-to addresses come from SYSPRO into Magento company accounts every night and when a new account is opened.
Prices. Standard price lists are synced to Magento on a schedule. For complex contract pricing, the cart asks SYSPRO for the customer's price through a query business object, with a short cache so the store stays fast.
Stock per warehouse is queried every 15 to 30 minutes and shown per location on the product page.
Orders are created in SYSPRO as sales orders through a transaction business object. If an order fails validation, for example because of a credit hold, it goes to a review queue for the sales team instead of being lost.
Order status, shipments and invoices flow back from SYSPRO, so customers can see them in their account instead of calling.
Monitoring. Every sync run is logged, and someone gets an alert if SYSPRO stops responding or a run fails.

The same approach works with WooCommerce for a smaller catalog. The SYSPRO side doesn't change; only the store side does.

How a Magento integration works

Mapping. For each piece of data, decide which system owns it and where it goes.
Connection. Magento has REST and GraphQL APIs; the other side may have an API, a database or files.
Sync rules. Real-time for orders and stock, scheduled for catalogue updates, on demand for large imports.
Error handling. Queues and retries, so a short outage of one system doesn't lose orders, and alerts when something needs a person.
Monitoring. After launch, someone watches the logs and fixes issues before customers notice.

What a Magento integration project includes

A typical integration project with us goes through the same steps, whatever the systems are:

Discovery and data map. Which systems, which data, which direction, how often, and what the business rules are (customer prices, warehouses, B2B accounts).
Fixed estimate. You get the scope, the timeline and a fixed price before development starts.
Build and test on staging, with real data samples from your ERP, CRM or PIM.
Launch without downtime, with the old process kept as a fallback until the sync is proven.
Monitoring and support, so failed syncs are caught by alerts, not by customers.

Project managers, QA and DevOps are part of the team, and we reply to any request within one business day.

How to choose a Magento integration partner

Experience with your systems. Ask which of your systems they have actually integrated, not which ones they could.
A plan before code. You should get a data map, a timeline and a fixed estimate before work starts.
Error handling. Ask what happens to an order if the ERP is down for an hour.
Support after launch. Integrations need care like the rest of the store.
Code you own. The integration should run on your infrastructure, with documentation.

Questions about Magento integrations

How long does a Magento ERP integration take?

It depends on the ERP, the amount of data and the business rules. A standard order and stock sync is faster than one with customer-specific prices and complex B2B logic. A good partner gives you a timeline after mapping the data, before any work starts.

Should we use a ready-made connector or a custom integration?

A ready-made connector is faster when your processes are standard. A custom integration fits when you have special pricing, several warehouses or rules the connector doesn't cover. Often the answer is a connector plus custom extensions.

Can Magento integrate with an ERP that has no API?

Yes. If the ERP can export and import files (XML, CSV or Excel), Magento can exchange data with it on a schedule, with validation and alerts. We have run B2B stores this way with legacy ERPs that could not be changed.

Can you integrate Magento with SYSPRO?

Yes. Depending on your rules, that means setting up a ready-made connector, extending it, or building the integration on SYSPRO's e.net business objects. The first step is a short review of your SYSPRO version, your e.net licenses and how prices, stock and orders are handled, followed by a fixed estimate.

Can Klaviyo, Mailchimp or Dotdigital use data from our ERP?

Yes. The email platform's Magento extension sends store data: customers, orders and carts. ERP data, such as customer type, contract terms or offline orders, needs one more step: either it is synced to Magento first and goes out with the extension, or it is sent from the ERP to the email platform directly through its API. The better option depends on whether Magento needs that data too.

Does an integration slow down the store?

It shouldn't. Heavy syncs run in the background and in queues, not while a shopper is loading a page. If your store slows down during imports, a performance audit shows why.

SYSINT has been building and integrating complex online stores since 2014: Magento stores connected to ERP, CRM, PIM and marketplaces, for manufacturers, wholesalers and retailers.
