Proposed workflow

Sales order process handoff

Planning example. Stacksync support for the required connection and record operations needs a technical review.

Starting eventA change involving BigCommerce Orders or Epicor ERP AR invoices needs a defined result in the other system.

  1. Start with BigCommerce Orders and Epicor ERP AR invoices. Use the record-matching and field-ownership rules from your mapping worksheet.

  2. Create or locate the customer and products first; resolve taxes, currency, and fulfillment references.

  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

What to verifyTest a partially invoiced order, tax rounding, and a repeated handoff without generating another invoice.

Compare integration approaches

Choose a method around one example record and the update your business needs. Use Orders / AR invoices to review record matching and confirm Stacksync support for the required operations. Compare ongoing sync, a custom workflow, and a scheduled export against that requirement.

Stacksync managed sync

Best fit
Review compatibility with a Stacksync engineer using an example of the records and updates you need.
Operating responsibility
Fits ongoing record synchronization when the required operations are supported. Add workflow steps for approvals or business actions that go beyond copying fields.
Before you choose
Check record matching: Link order and line IDs to invoice and line IDs; allow partial invoicing and multiple invoices per order. Verify field coverage, deletion handling, and how changes are detected.

Native vendor integration

Best fit
A vendor-built integration may fit if it supports your BigCommerce and Epicor ERP record types.
Operating responsibility
Can reduce setup for a supported workflow. You may need another method for records or business steps it does not cover.
Before you choose
First check whether either vendor offers this integration. If available, verify Orders / AR invoices, update direction, account tier, and related-record handling.

Custom API or workflow

Best fit
Consider explicit orchestration for the Orders / AR invoices handoff.
Operating responsibility
Provides control over business steps; the team owns credentials, version changes, error queues, and reconciliation.
Before you choose
Verify endpoint permissions, pagination, quotas, duplicate detection, and failure recovery. Separate reading history from actions that send messages, grant access, or post transactions.

File or scheduled snapshot

Best fit
Consider for a one-time BigCommerce / Epicor ERP migration or a reporting need with an explicit freshness window.
Operating responsibility
Can simplify a bounded transfer; later changes and deletion history require another extraction or a separately designed incremental process.
Before you choose
Record the extraction cutoff, source IDs, encoding, date/number formats, and reconciliation totals.

Workflow scenarios and expected results

Sales order process handoff

Planning example. Stacksync support for the required connection and record operations needs a technical review.

Starting event: A change to the selected Orders or AR invoices record needs a defined result in the other system.

  1. Start with BigCommerce Orders and Epicor ERP AR invoices. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Create or locate the customer and products first; resolve taxes, currency, and fulfillment references.
  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

Expected result: Test a partially invoiced order, tax rounding, and a repeated handoff without generating another invoice.

If it fails: Check for an existing destination order before retrying a timed-out create; reconcile line IDs to avoid duplicate fulfillment.

Customer sync test

Planning example. Stacksync support for the required connection and record operations needs a technical review.

Starting event: A change to the selected Customers or Customers record needs a defined result in the other system.

  1. Start with BigCommerce Customers and Epicor ERP Customers. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Resolve person or company type, legal entity, business role, and any billing account before transactions.
  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

Expected result: Test an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact.

If it fails: Hold ambiguous customer matches for review and resolve customer type before retrying dependent records.

Reconcile Epicor ERP business records with BigCommerce

This is an evaluation scenario; connector and operation support require confirmation.

Starting event: A finance-owned record in Epicor ERP needs operational visibility through Products or Variants and SKUs.

  1. Select Customers or Suppliers with the correct legal entity, period, and currency.
  2. Define a reporting relationship in BigCommerce; do not equate customer records, ledger accounts, and posted transactions.
  3. Decide whether the process only reports a financial state or requests an approved accounting action, and maintain a separate transaction ID for each action.

Expected result: Totals reconcile within the same entity/currency/window; a repeated handoff creates no duplicate financial transaction.

If it fails: Verify posting and settlement state before retrying. Use the approved adjustment path for already-posted transactions.

Initial load and acceptance testing

Keep both record IDs with the expected and actual result. Reconcile the same filters and time window in each system.

Orders / AR invoices

Test case

Test a partially invoiced order, tax rounding, and a repeated handoff without generating another invoice.

Expected result

The expected sales order relationship is preserved with no duplicate action or unintended write.

Orders / Shipments

Test case

Test partial fulfillment, an out-of-stock line, and a repeated request that must not create a second shipment.

Expected result

The expected sales order relationship is preserved with no duplicate action or unintended write.

Customers / Customers

Test case

Test an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact.

Expected result

The expected customer relationship is preserved with no duplicate action or unintended write.

Orders / Sales orders

Test case

Test a multi-line order, a partial cancellation, and two partial shipments. Compare line totals as well as the header.

Expected result

The expected sales order relationship is preserved with no duplicate action or unintended write.

Direction and permissions

Test case

Bring an example source record and the intended destination operation to the compatibility review. Confirm the supported route before granting write access.

Expected result

Only an approved, supported direction and permitted fields are written.

Freshness and reconciliation

Test case

Measure source and destination times for the selected records under normal load and a burst. Reconcile IDs and values using the same filters and cutoff.

Expected result

The process meets its agreed freshness target and reconciliation has no unexplained differences.

Failed updates, retries and recovery

Start with the failed record and the destination error, then inspect the source value, field requirements, and access.

Rejected or repeated sales order change

Investigate

Inspect BigCommerce Orders and Epicor ERP AR invoices, their IDs, and the destination error.

Next action

Check for an existing destination order before retrying a timed-out create; reconcile line IDs to avoid duplicate fulfillment.

Rejected or repeated sales order change

Investigate

Inspect BigCommerce Orders and Epicor ERP Shipments, their IDs, and the destination error.

Next action

Check for an existing destination order before retrying a timed-out create; reconcile line IDs to avoid duplicate fulfillment.

Rejected or repeated customer change

Investigate

Inspect BigCommerce Customers and Epicor ERP Customers, their IDs, and the destination error.

Next action

Hold ambiguous customer matches for review and resolve customer type before retrying dependent records.

A record type or update is unavailable

Investigate

Check the BigCommerce and Epicor ERP connector guides, account permissions, and any operations marked On Request.

Next action

Ask the integration team to confirm a supported way to handle that record. Verify whether it needs connector configuration or a separate workflow step.

Source and destination disagree after a retry

Investigate

Compare current source values, destination validation, identity mappings, and any side effects already completed.

Next action

Stacksync issue retry reads the current source state. Decide the intended state before retrying or reverting; reconcile downstream effects separately.

Read the Stacksync issues dashboard guide for retry and revert behavior.
