Most Magento integration pain comes from one unanswered question: for each field, which system is right when the two disagree? Answer it per field and the integration becomes a contract that can be tested. Leave it unanswered and you get point-to-point scripts, a manual correction rota, and a roadmap that is mostly maintenance.
Direct answer
Magento integrates with an ERP, PIM, CRM or OMS through its REST and GraphQL APIs, usually with a message queue between them so neither system has to be available for the other to keep working. The technical connection is the easy part. What makes an integration reliable is an explicit contract: for every field, which system is the source of truth, how often it syncs, what happens when a message fails, and how the two sides are reconciled when they drift. Integrations built as point-to-point scripts without that contract turn every schema change on either side into an outage.
Best suited for
- ERP as the system of record for stock and price
- B2B ordering with quotes, contracts and approvals
- PIM-driven catalogues at scale
- Order and fulfilment flows spanning several systems
The problem
The symptom as the person carrying it would describe it, and the part that shows up in the numbers rather than in the ticket queue.
Stock is wrong often enough that people check manually
What it costs
Oversells, cancellations and a support rota built around distrust of the platform. The manual check becomes the process, and its cost is never counted because nobody logs it as a ticket.
Every schema change on either side is an outage
What it costs
The integration was built as scripts against whatever the fields happened to be called. Both systems become frozen, and any improvement to either is priced as an integration project.
B2B orders wait on people, twice
What it costs
Quotes, negotiated pricing and approval chains run through email and a spreadsheet. The delay is not the software, it is people waiting for each other, and it is felt by the customer as a slow supplier.
Nobody can say which system is right
What it costs
Magento and the ERP disagree on a price and the answer depends on who is asked. Without a per-field source of truth the disagreement cannot be resolved by rule, so it is resolved by a person, every time.
Approach
In this order, and the order is the opinion. Most of what goes wrong on this kind of engagement is a step taken before the one it depends on.
Name the source of truth per field
Not per system. Stock may belong to the ERP while merchandising copy belongs to the PIM and promotional price belongs to Magento. Writing this down is unglamorous and it settles most of the arguments the integration would otherwise cause.
Write the contract
Fields, direction, frequency, and the behaviour on failure. A contract makes the integration testable, which means a change on either side can be verified rather than discovered.
Build with a queue between
Message queues over the Magento API so neither system needs the other to be up. Point-to-point synchronous calls make each system a dependency of the other, which is how one supplier maintenance window stops the store taking orders.
Model the workflow explicitly
On B2B platforms, approvals, quotes and company accounts are data structures in Magento rather than a plugin, so they can be reported on and changed. This is what Magento is actually for, and it is where the platform earns its cost.
Reconcile, and alert on drift
Scheduled comparison across the boundary with the differences classified rather than dumped into a report nobody opens. It reports; it does not auto-correct, because automatic correction across a boundary turns a small discrepancy into a large one.

Outcome
90%
Of B2B order and quote processing automated
Approval chains modelled in Magento as a data structure rather than as email, across development, B2B orders, quotes and vendor management. The first version was deterministic rather than generative, which is why it was trustworthy enough to leave running.
Where this came from
From the verified delivery record on a B2B procurement platform: approximately 90% of B2B order and quote processes automated.
40%
Cut in approval cycle time
The commercial effect of the same work. On a B2B platform the delay customers actually feel is the wait between people, not the page load, and it is the number worth moving.
Where this came from
From the same B2B procurement platform, measured against the approval process it replaced.
Both figures come from one B2B procurement platform and describe the process it replaced. A business whose approvals are already partly automated has less headroom, and the same percentages would not be honest applied to it.
Questions
- How do you decide which system owns a field?
- By asking where the value is actually created and who is accountable for it being right. Stock is created by the warehouse, so it belongs to the ERP or the WMS. Merchandising copy is created by the merchandising team, so it belongs to the PIM or to Magento. The test is simple: when the two disagree, whose answer would you act on?
- Should Magento integrations be real time?
- Rarely all of them. Stock usually needs to be near real time because the cost of being wrong is an oversell; product copy can sync on a schedule; order export can queue. Making everything real time raises cost and coupling, and makes the store dependent on the ERP being available.
- What happens when the ERP is down?
- With a queue between the systems the store keeps trading and messages are delivered when the ERP returns. Without one, an ERP maintenance window becomes a commerce outage, which is the single strongest argument for not building integrations as direct synchronous calls.
- Can AI help with integration work?
- It helps most with reconciliation and with the data quality either side of the boundary: finding where two systems disagree, and drafting the catalogue attributes that arrive incomplete. It should not be making the correction. A system that can silently rewrite a value across a boundary turns a small discrepancy into a large one.
- Does Magento need Adobe Commerce for B2B?
- The Adobe Commerce B2B module supplies company accounts, requisition lists, quotes and negotiable pricing out of the box. The same behaviour can be built on Open Source, and whether it is worth it depends on how far your approval and pricing rules diverge from the module. The comparison is licence cost against build and maintenance cost, not features against features.
