Custom Shopify ↔ Sage 300 integration, built around your workflow — not a generic connector.
A real-time integration between your Shopify storefront and Sage 300 (formerly Accpac) — orders, stock, customers, invoices and Stripe payouts moving automatically between the two. Senior engineers, fixed-scope build, code that’s yours, EU data residency.
Every entity Shopify and Sage 300 need to agree on.
Order in Shopify → invoice in Sage 300. Refund in Shopify → credit note in Sage 300. Stripe payout → reconciled bank entry. No manual exports, no end-of-month spreadsheet reconciliation, no “where did this €4,231 come from” questions from finance.
Orders → Sage 300 OE
Shopify orders land as Sage 300 Order Entry documents with the right company, customer, ship-to, tax authority, GL accounts and item lines. Multi-currency and multi-tax respected.
Inventory ↔ Shopify
Sage 300 IC stock levels (multi-location, multi-warehouse aware) push to Shopify in near real time. Optional safety-stock and channel-allocation rules per SKU.
Items, pricing & price lists
Sage 300 stays the source of truth for items and pricing. Customer-specific price lists, contract pricing and discount classes flow through to Shopify B2B checkout.
Customers & AR contacts
Customer master moves both ways. Web customers land in Sage 300 with the right customer class and salesperson. AR-customer pricing and credit terms flow into Shopify.
Invoices & credit notes
Shipment in Sage 300 generates the OE invoice. Shopify refund triggers a Sage 300 credit note. Your finance team posts to the GL once — not twice in two systems.
Stripe payout reconciliation
Stripe / Shopify Payments deposits reconcile against orders, fees, refunds and FX so the bank entry in Sage 300 ties out to the underlying transactions automatically.
The hours you spend stitching Sage 300 and Shopify together — back.
We replace the exports, the macros and the “Mary copies the figures across on a Tuesday morning” ritual with a real-time, monitored, idempotent pipeline. You keep your accounting source of truth in Sage 300; Shopify just becomes another channel that posts cleanly.
Stop the “export Shopify orders to CSV, run the macro, import into Sage 300” daily ritual. Replace it with webhook-driven, idempotent sync.
Stop month-end Stripe reconciliation. Every payout maps to Sage 300 bank entries with full breakdown.
Stop oversells because the Sage 300 batch ran at 06:00 and you sold the last unit at 09:14. Stock sync is near-real-time.
Stop maintaining the in-house Python script that crashes whenever someone’s Sage 300 password expires.
Stop the “why isn’t my B2B account seeing trade prices” calls. Sage 300 price lists drive Shopify pricing.
You own the code. EU data residency. No vendor lock-in.
Built using Sage 300 web services (where available) and the Sage 300 SDK / .NET interop for the modules that haven’t exposed a clean REST surface. We pick the right interface per entity, not one-size-fits-all.
Queue-based middleware (Python + Postgres + Redis) handles back-pressure. A burst of Shopify webhooks gets queued and delivered at a rate Sage 300 is comfortable with — no batch-job collisions.
Every operation is idempotent. Failures are visible in a small ops dashboard your team can see, and re-runnable with one click. Nothing is silently lost.
You own the source code. Git repo, infrastructure-as-code, a runbook and a 30-day post-launch warranty are part of the handover. Self-host or keep us on retainer — your call.
Shopify ↔ Sage 300 — what people actually ask.
Do you support Sage 300 (Accpac) on-prem and Sage 300cloud?
Yes. We work with current Sage 300 and Sage 300cloud builds. The integration surface differs by edition and hosting — we confirm in the discovery call.
What if our Sage 300 is partner-hosted?
Common scenario. We work with your hosting partner to expose the web services / VPN we need, and the middleware lives in our EU region. Most hosting partners are familiar with this pattern.
Can the integration handle multi-company Sage 300?
Yes. Order routing rules pick the correct Sage 300 company per Shopify store / region / product. Multi-currency and inter-company netting are also supported.
Is this a real-time integration?
Orders and refunds are real-time. Stock is near-real-time (configurable cadence). Customer and item masters sync on change, plus a nightly reconciliation pass.
How much and how long?
Fixed-scope projects typically run €20k–€60k depending on catalogue and B2B complexity. Most go live in 6–10 weeks. You get a fixed-scope proposal after the 20-minute discovery call.
