Connect Sage X3 + BigCommerce
Automate sales order, customer / trade account, product and price list, stock availability, shipment / delivery confirmation between Sage X3 and BigCommerce — with monitoring and managed support from APIWORX.
APIWORX connects the systems your business already uses and takes responsibility for the agreed integration workflows after go-live. The exact objects, direction and cadence are fixed in writing during scoping.

APIWORX Provides the Service
Yes. APIWORX connects Sage X3 and BigCommerce.
But connecting the applications is only the beginning. The work that costs you time sits in the process running between them.
APIWORX automates that process end to end — the objects moving between Sage X3 and BigCommerce, the ownership rules that decide which system wins, the exceptions when a record will not post, and the monitoring that tells someone before your team finds out from a customer.
How it works
From requirements to a managed integration
We Design the Integration
APIWORX recommends the integration architecture, mappings and implementation approach.
We Build, Monitor & Support It
APIWORX implements the integration and provides ongoing monitoring and support as applicable.
Who this is for
This page is for distribution and manufacturing teams running Sage X3 who sell to trade customers through BigCommerce.
What needs to be in place
- Sage X3 with API access and a service user permitted to create the documents in scope.
- A BigCommerce store (including B2B Edition where you use it) with API credentials available.
- An agreed view of which customers, price lists and units of measure the store may expose.
- A warehouse or 3PL process capable of returning despatch and tracking detail.
When you may not need this
A small catalogue with a handful of daily orders can often be handled by a store's own accounting export. This page is for teams where account-specific pricing, unit-of-measure conversion or stock accuracy make manual handling expensive.
What is out of scope
- APIWORX does not rewrite your Sage X3 pricing or unit-of-measure configuration; the integration applies the rules X3 already holds.
- Unit-of-measure handling — case, pack, each and any conversion factors — is confirmed in scoping because it varies by X3 configuration.
- Storefront design, checkout UX and BigCommerce theme work are out of scope.
What actually moves, and who owns it
A representative BigCommerce and Sage X3 scope. Objects, direction and system of record are confirmed per customer before build.

| Object | From | To | System of record | Trigger | If it fails | Owner |

| Sales order | BigCommerce | Sage X3 | BigCommerce at capture, X3 after posting | Order placed and payment state agreed | Held in exception queue with the validation error | APIWORX |
| Customer / trade account | Sage X3 or store registration | Both | Sage X3 | New or changed account | Unmatched account raises a named exception | APIWORX (delivery) / you (approval) |
| Product and price list | Sage X3 | BigCommerce | Sage X3 | Item or price change | Retried, then queued with the rejected field | APIWORX |
| Stock availability | Sage X3 | BigCommerce | Sage X3 | Agreed publishing cadence | Last published figure retained; exception raised | APIWORX |
| Shipment / delivery confirmation | Sage X3 or warehouse | BigCommerce | Despatch record | Delivery confirmed | Retried, then queued for review | APIWORX |

Three decisions that make or break this integration
Trade accounts buying at their own prices
B2B buyers expect to see their negotiated price, not list. Rather than duplicating a pricing matrix in the storefront, the integration publishes the price list Sage X3 already holds for that account, so a change made once in X3 is what the buyer sees.
- Account-to-customer matching agreed up front, so an order never lands against the wrong X3 account.
- Price list selection follows X3 rules rather than a second set maintained in the store.
- Accounts on credit hold or stop are handled as an explicit decision, not a silent rejection.
- New accounts created in the store are held for approval where you want a credit check first.
Units of measure that survive the handoff
Selling by case while stocking by each is where most distribution integrations break. The conversion behaviour is confirmed during scoping and then applied consistently, so an ordered quantity does not silently become the wrong quantity in X3.
- Selling unit and stocking unit mapped per item, with the conversion factor taken from X3.
- Unmapped or ambiguous units stop the line with a named exception instead of guessing.
- Minimum order quantities and pack rounding treated as agreed business rules.
- Whether your X3 configuration supports the conversion you need is verified before build.
Stock the storefront can be trusted on
Overselling costs more than a missed sale. Availability is published from X3 on an agreed cadence with an agreed calculation, so what appears online reflects a defined rule rather than an assumption.
- Which warehouses and stock statuses count toward availability agreed with your team.
- Buffers and safety stock applied as a documented rule per item or group.
- Publishing cadence agreed in scoping; this page does not claim real-time stock.
- A failed publish keeps the last known figure and raises an exception rather than zeroing the store.
Reliability and ownership
The operating rules that apply to this workflow after go-live.
- Every run is logged with the source record reference so an order, shipment or stock update can be traced end to end.
- Failed messages are retried on a defined schedule; anything that still fails lands in an exception queue rather than being dropped silently.
- Duplicate prevention keys on the source system's own identifier (order number, shipment ID, SKU).
- Exceptions are worked by the APIWORX team and escalated to your named operations contacts when a business decision is needed.
- Mapping changes — new SKUs, new locations, new warehouses, new channels — are part of the ongoing engagement.
- Support windows and response commitments live in your agreement; this page does not state an SLA.
How an order is traced
Illustrative — not customer data
An illustrative reference trace between the BigCommerce record and the Sage X3 document chain.
| BigCommerce order ID | Sage X3 sales order number |
|---|---|
| Store customer / company | Sage X3 customer account |
| Despatch record | Tracking reference on the store order |
| Sage X3 invoice number | Reference shown against the store order |
Scope and questions
- Do you support BigCommerce B2B Edition?
- Which B2B Edition features are in scope — company accounts, buyer roles, quoting — is confirmed during scoping against your store configuration. We do not assume the full feature set applies.
- Is stock updated in real time?
- No. Availability is published on an agreed cadence with an agreed calculation. We state the cadence in your scope rather than promising instant updates.
- Which Sage X3 version do you work with?
- Version, deployment model and available API access are confirmed in scoping. We do not list supported versions here because it depends on your environment.
- Who maintains the mapping afterwards?
- APIWORX does, as part of the ongoing engagement — new items, new accounts, new price lists and new warehouses included.
