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 BILL Invoices or NuORDER Orders needs a defined result in the other system.

  1. Start with BILL Invoices and NuORDER Orders. 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.

Business process

Invoices / Orders

Order-to-invoice handoff: NuORDER Orders provides context for BILL Invoices. These are related records, not equivalent entities.

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

BILL
Object support to establish
NuORDER
Object support to establish
Record identity
Link order and line IDs to invoice and line IDs; allow partial invoicing and multiple invoices per order.
Field ownership
Finance owns invoice posting; the order system supplies the approved commercial context.

Fields to include

  • Source record reference
  • Destination record reference
  • Approved handoff state
  • Duplicate-detection key
Record dependencies
Create or locate the customer and products first; resolve taxes, currency, and fulfillment references.
Validation
Test a partially invoiced order, tax rounding, and a repeated handoff without generating another invoice.
Recovery
Check for an existing destination order before retrying a timed-out create; reconcile line IDs to avoid duplicate fulfillment.

Customer identity

Customers / Companies

Before linking BILL Customers to NuORDER Companies, check whether the customer is an individual or a company. Match the correct record type in each system.

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

BILL
Object support to establish
NuORDER
Object support to establish
Record identity
Determine whether each customer represents an individual, a company, or a business-unit relationship before matching it to a contact or organization. Retain the source customer ID and destination ID; names and email alone are insufficient.
Field ownership
Separate the customer relationship from contact details, billing authority, and consent. Choose an owner for each field after identifying whether the customer is a person or company.

Fields to include

  • Source customer ID
  • Person/company classification
  • Legal entity or business unit
  • Destination identity reference
Record dependencies
Resolve person or company type, legal entity, business role, and any billing account before transactions.
Validation
Test an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact.
Recovery
Hold ambiguous customer matches for review and resolve customer type before retrying dependent records.

Record matching

Payments / Payments

Compare whether BILL Payments and NuORDER Payments describe the same payment or settlement in your business.

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

BILL
Object support to establish
NuORDER
Object support to establish
Record identity
Preserve transaction ID, provider/source, currency, and links to invoices; one payment may settle several documents.
Field ownership
Keep payment authorization, settlement, and accounting allocation distinct.

Fields to include

  • Source transaction ID
  • Invoice references
  • Amount and currency
  • Settlement status
  • Reversal reference
Record dependencies
Resolve the affected invoices and cash/account references before allocating the payment.
Validation
Test partial payment, one-to-many allocation, refund, and repeated delivery of the same transaction.
Recovery
Look up the original transaction before retrying to prevent duplicate allocation or charging.

Compare integration approaches

Choose a method around one example record and the update your business needs. Use Invoices / Orders 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 BILL and NuORDER 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 Invoices / Orders, update direction, account tier, and related-record handling.

Custom API or workflow

Best fit
Consider explicit orchestration for the Invoices / Orders 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 BILL / NuORDER 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 Invoices or Orders record needs a defined result in the other system.

  1. Start with BILL Invoices and NuORDER Orders. 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 Companies record needs a defined result in the other system.

  1. Start with BILL Customers and NuORDER Companies. 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.

Payment or settlement sync test

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

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

  1. Start with BILL Payments and NuORDER Payments. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Resolve the affected invoices and cash/account references before allocating the payment.
  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 partial payment, one-to-many allocation, refund, and repeated delivery of the same transaction.

If it fails: Look up the original transaction before retrying to prevent duplicate allocation or charging.

Reconcile BILL business records with NuORDER

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

Starting event: A finance-owned record in BILL needs operational visibility through Products or Orders.

  1. Select Bills or Vendors with the correct legal entity, period, and currency.
  2. Define a reporting relationship in NuORDER; 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.

Invoices / Orders

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.

Customers / Companies

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.

Payments / Payments

Test case

Test partial payment, one-to-many allocation, refund, and repeated delivery of the same transaction.

Expected result

The expected payment or settlement 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 BILL Invoices and NuORDER Orders, 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 BILL Customers and NuORDER Companies, their IDs, and the destination error.

Next action

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

Rejected or repeated payment or settlement change

Investigate

Inspect BILL Payments and NuORDER Payments, their IDs, and the destination error.

Next action

Look up the original transaction before retrying to prevent duplicate allocation or charging.

A record type or update is unavailable

Investigate

Check the BILL and NuORDER 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.
