Most EDI-to-Shopify projects fail because nobody on the Shopify side understood the ERP. We do. Trading-partner EDI compliance, ERP-driven pricing and inventory, custom API middleware between Shopify and whatever system actually runs your client's business — scoped and built without guessing at how Shopify's data model works.
EDI trading-partner compliance and multi-document ERP sync scope higher — priced after a real audit of document volume and ERP-side complexity, not a flat rate.
An 850 that maps cleanly into NetSuite's SuiteScript layer doesn't touch SAP's IDoc structure the same way. Most stalled EDI-to-Shopify projects aren't failing because EDI is hard — they're failing because whoever built the Shopify side didn't actually understand the ERP on the other end, or vice versa.
Its data model assumes a different source of truth than SAP or NetSuite expects. Mapping between them takes real Shopify-side knowledge, not just EDI expertise.
Every retailer's 856 requirements — SSCC-18 labels, carton counts, routing codes — differ slightly. Generic mapping fails compliance checks on the first real shipment.
If an order changes between acknowledgment and shipment, and each document is generated by a different system, the mismatch surfaces at the worst possible time — on the receiving dock.
EDI transaction sets mapped to Shopify's order, fulfillment, and inventory objects — matched to your ERP's actual data structure, not a generic template.
Where a pre-built connector doesn't cover the workflow, we build direct against the Shopify Admin/GraphQL API and your ERP's API or IDoc layer.
ASN label formats, SSCC-18 barcodes, routing/SCAC codes — built and tested against the specific retailer or partner spec, not assumed generic.
A clear architecture decision for which system owns pricing, inventory, and order status — so the 850/855/856/810 chain stays consistent end to end.
Full document cycles tested against trading-partner specs before anything goes live, so the first real PO isn't the first real test.
Every mapping and integration point documented clearly enough for your ERP team — or ours — to maintain it going forward.
We map what's actually moving between Shopify, your ERP, and your trading partners today — including the manual workarounds nobody documented.
SCOPED AFTER A REAL AUDITA written plan for which system owns which data, and how each EDI document maps to Shopify's model — reviewed before any build starts.
Middleware and mapping built, then run through full document cycles against real trading-partner specs before go-live.
Live monitoring on the document chain, plus documentation so the integration doesn't depend on us indefinitely.
No flat price before we've actually seen your document volume and ERP complexity — EDI/ERP scope varies too much to guess.
Full document simulation against real trading-partner specs, not a hope that the first live PO works.
Built so your team — or your ERP consultant — can maintain it without depending on us forever.
If you're an ERP or EDI consulting firm and a client's project suddenly has a Shopify storefront on one end of it, that's usually the piece outside your core practice — and the piece where a generic web agency will burn weeks relearning what you already know about the client's document flow.
Cartwright plugs in as the Shopify-side execution partner: theme and storefront work, Shopify Admin API and webhook development, and the mapping work that connects your ERP-side integration to Shopify's actual data model. You keep the ERP relationship and the architecture call. We handle the half of the stack that isn't your specialty.
No — we work with whatever EDI network or translator is already in place (AS2, SFTP, VAN) and build the mapping between that layer and Shopify. We're not selling a replacement EDI platform.
The list covers what we see most often, not a hard limit. If it has an API, IDoc layer, or file-based export, it's very likely workable — tell us what you're running and we'll give you a straight answer on the audit call.
Flexible by design — we can quote the client directly, quote through you, or work out a referral structure that fits how you already run partner relationships. This gets settled in the first conversation, not assumed in advance.
No. We're not an ERP consultancy and have no interest in becoming one. Our scope stays on the Shopify side — theme, storefront, API, and document mapping — by design, not just by courtesy.
A real systems and document audit first — priced per engagement, not a guess.
