BigCommerce ↔ Sage 200 Integration
BigCommerceE-commerce platformSaaS storefront, on-prem ledger — BigCommerce orders into SOP, Sage stock and pricing back to the catalogue.
BigCommerce gives you a hosted storefront; Sage 200 stays the source of truth for stock, pricing and accounts. We build the middleware between them: orders flow into Sage as SOP documents, product and stock data flows out to BigCommerce, and despatch tracking writes back so the customer experience closes the loop.
Data Flows
- 1
Orders → SOP
BigCommerce orders (via webhooks or scheduled API poll) create Sage 200 sales orders — customer matching, SKU-to-stock-code mapping, shipping method to delivery method, tax handled per Sage's rules.
- 2
Catalogue → BigCommerce
Products, stock levels and price bands publish from Sage to BigCommerce on a schedule. Variants and option sets map to Sage stock codes via a mapping table you control.
- 3
Despatch → tracking
SOP despatch notes push fulfilment status and tracking numbers back to BigCommerce, triggering its shipment emails.
- 4
Payments & refunds
BigCommerce payment captures post to Sage's cash book against the invoice; refunds create credit notes, keeping the ledger clean without a reconciliation spreadsheet.
Where These Integrations Go Wrong
The failure modes we design around — most BigCommerce ↔ Sage projects hit at least two of these.
Webhooks aren't a sync strategy
BigCommerce webhooks can be delayed, deduplicated or missed. We use them to trigger near-real-time import but keep a scheduled full-reconcile poll as the safety net.
Variant SKUs vs stock codes
BigCommerce variants must map to real Sage stock codes — a product with 12 variants needs 12 codes, or BOM/kit logic on the Sage side. Sort the mapping table before go-live.
Guest checkout accounts
Guest orders still need a Sage ledger — typically a single web-sales account with the customer's details on the order, not thousands of one-use ledgers.
Multicurrency storefronts
If you sell in multiple currencies, decide whether Sage holds foreign-currency orders or converts at settlement — it changes how invoices post and how VAT reports.
What's Included
- Order import: BigCommerce → Sage 200 SOP with customer and SKU mapping

- Despatch and tracking writeback
- Payment posting and refund credit notes
- Scheduled reconciliation — orders, payments and stock counts compared and exceptions queued
Who It's For
Sage 200 merchants moving to (or already on) BigCommerce who need the store to run off live Sage stock and pricing.
FAQ
Is there an off-the-shelf BigCommerce–Sage 200 connector?
Integration platforms (Patchworks, VL Omny and similar) list both systems, and they're worth pricing first. The bespoke build earns its keep when your pricing bands, BOMs or warehouse logic don't fit the connector's data model — we can also fill the gaps a platform leaves rather than replacing it.
How do BigCommerce orders become Sage invoices?
Orders import as SOP documents, allocate stock, despatch, then invoice — the normal Sage flow. Payment captured by BigCommerce posts to the cash book and closes the invoice, so Sage stays the accounting record.
Can you sync B2B price lists?
Yes — BigCommerce B2B Edition customer groups can map to Sage price bands, so trade customers see their negotiated pricing. Without B2B Edition we can still gate pricing behind a login via a customer-group workaround.
Does this work with Sage 50 instead of Sage 200?
Usually yes — the BigCommerce side of the integration stays the same; what changes is how we get data in and out of Sage. Sage 50 has no REST API, so we use the SDK (SDO), SData, ODBC reads or a lightweight connector service installed next to Sage. The data flows described above map onto Sage 50 customers, invoices and stock records the same way — tell us your Sage version and we'll confirm the method before quoting.
