Acumatica Shopify Integration Experts

An Acumatica Shopify integration links your store to Acumatica Cloud ERP so orders, inventory, pricing, customers, payments, returns, shipments and financials move between the two without rekeying. The connector is built into Acumatica's Retail Edition, and the store side installs through the free Acumatica Cloud ERP app. It covers online orders, Shopify POS and B2B on Shopify. Most of the work is deciding which system owns what. Which side sets each price. How stock per warehouse reaches the right Shopify location. How a refund lands in the books. Whether one store or several feed a single Acumatica instance. This work usually sits with an Acumatica reseller that runs commerce projects, or with an integration developer who knows the ERP well. Should the listing below come up short, the API integration and inventory management services linked lower down handle the same Acumatica mapping jobs. Have four things ready before any call: your Acumatica edition, your Shopify plan, how many stores and locations you run, and whether B2B is in scope.

What an Acumatica developer maps between the ERP and Shopify

The connector does the transport. Somebody still has to decide what each record means on both sides, and that decision is where Acumatica projects go right or wrong.

Entity mapping. Products with titles, descriptions, categories, prices and images; inventory per location; customers; orders; payments and refunds. Each needs a rule for which system creates it and which only updates it. The sync is real-time and runs both ways, so a bad rule spreads fast.

B2B on Shopify. Setting up companies with several buyers each, sending customer-specific pricing from Acumatica to Shopify, and mapping Shopify payment terms to Acumatica credit terms. A business selling to trade and consumers can serve both from one blended Shopify store.

Shopify POS. Configuring the import settings for in-store transactions so till sales reach Acumatica alongside online orders. Returns taken in a shop need the same treatment, or stock and refunds drift apart.

Several stores, one ERP. Acumatica connects to as many Shopify stores as you operate. An expert sets stock allocation so each store sells only what it can actually ship.

Fulfilment and fraud. Automating fulfilment from the Acumatica side, and surfacing Shopify's fraud analysis inside Acumatica so risky orders get flagged before anyone picks them.

Migration and extensions. Moving data across from another ERP or accounting system, building custom extensions where the standard connector stops, and tracing sync errors once orders are flowing.

Reseller or integration specialist: choosing Acumatica help

Acumatica has no direct sales team. The ERP is sold only through value-added resellers, so if you already run Acumatica, you already have a reseller. The real question is whether that reseller has run a Shopify connector project, or whether you need an integration developer alongside them.

Ask for a finished Shopify project. Not an ERP rollout in general. A store with live orders, POS if you use it, and refunds that reconcile.

Ask which integration they're quoting. Acumatica's material describes two: the Shopify and Shopify POS connector, and the B2B on Shopify integration. A quote that covers one when you need both will grow later.

Get the edition in writing. Confirm which Acumatica edition and licence you hold before anyone builds. The Shopify connector depends on it.

Walk away if there is no test environment, nobody can say how a Shopify refund appears in Acumatica, or custom code is proposed before the standard connector has been tried.

Test them on a slice. Pay them to map ten products, two locations and one test order end to end, refund included. You'll learn more from that than from a sales call.

The Acumatica Partner Program covers resellers, ISVs, services partners and OEM developers. Where partner status matters, get the firm's role in writing and check it with Acumatica.

What to settle before the Acumatica Shopify connector goes live

Edition names have shifted. Current Acumatica pages say the Shopify connector is built into the Retail Edition. Older Acumatica Open University material calls it the Commerce Edition. Same idea, different label, so confirm with your reseller what your licence actually includes.

The store connects through an App Store app. That is the Acumatica Cloud ERP app on the Shopify App Store, and it matters because custom apps changed in January 2026. From 1 January 2026, Shopify stopped letting merchants make new legacy custom apps in the admin, though older ones still run. If an earlier integrator connected anything to your store that way, a good expert notes it and plans any replacement through the App Store app or Shopify's Dev Dashboard.

B2B is no longer Plus-only. Since 2 April 2026, Shopify's Basic, Grow and Advanced plans include company profiles, payment terms, volume pricing and up to 3 active B2B catalogues. Check which of those your plan supports before scoping the B2B sync. Unlimited catalogues, partial payments and deposits remain Plus-only.

POS has its own settings. In-store transactions import through separate POS settings in Acumatica. Decide early whether each shop maps to its own warehouse.

Multi-store is a design choice. Connecting several stores to one instance is supported. The allocation rules decide which store sells what, and they need testing before a sale, not during one.

Acumatica Shopify integration questions before you sign

What does an Acumatica Shopify integration cost?

There's no public price list. Acumatica tailors pricing by applications, transaction and resource usage and licence type, with unlimited users, and quotes it through its resellers. The Shopify and B2B on Shopify integrations are included in the Retail Edition, and the Shopify app is free to install. Implementation time is the separate line, so ask for it scoped by project.

Does an Acumatica integration need custom code?

Usually not at the start. The standard connector already covers orders, inventory, pricing, customers, payments, returns and shipments. Custom extensions earn their place when a field or process genuinely falls outside it. Ask for a written mapping first; code that arrives before the mapping usually means nobody read the connector settings.

Why aren't some Shopify orders reaching Acumatica?

Start with the failed order itself, then check that its products, location and payment method each have a mapping on the Acumatica side. Look closely at products created directly in Shopify: if the ERP has never seen them, there is nothing to map to. If stock levels are the symptom rather than orders, read our inventory sync troubleshooting guide before touching the ERP.

Who supports the Acumatica integration after go-live?

Acumatica's resellers handle evaluation, implementation, training and ongoing support of the ERP. That doesn't automatically include your Shopify store. Agree in writing who owns sync errors, changes to products and locations, and updates to the Shopify app, so a failed order on a Saturday has a name next to it.

Which side should be the master for B2B prices and payment terms?

Acumatica, going by how the integration is built. The B2B on Shopify integration sends customer-specific pricing from Acumatica to Shopify and maps Shopify payment terms to Acumatica credit terms. Agree that trade prices and terms are edited in Acumatica only, write it into the handover notes and tell the sales team, so nobody fixes a price in the Shopify admin instead.
