Example workflow

Customer sync test

Use writable fields from the connected accounts. Read values from read-only fields without writing changes back to them, and define deletion handling separately.

Starting eventA change involving HubSpot Company or Rillet Customer needs a defined result in the other system.

  1. Start with HubSpot Company and Rillet Customer. 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.

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

Why teams connect HubSpot and Rillet

Put your HubSpot and Rillet data to work

Start with the work your team needs to complete: keep records up to date, make operational data available for reporting, or move data to a new system. Choose one HubSpot and Rillet workflow to test, define what success looks like, and decide who handles failed updates.

  • Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.

  • Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.

  • Keep customers and invoices aligned between Rillet and a CRM so finance and sales work from the same account records.

  • Mirror journal entries and contract revenue data into a warehouse for board and ARR reporting.

What records can you sync?

Start with the records your workflow needs. Check each system’s read and write requirements before mapping fields.

Customer identity

Company / Customer

Before linking HubSpot Company to Rillet Customer, check whether the customer is an individual or a company. Match the correct record type in each system.

Use writable fields from the connected accounts. Read values from read-only fields without writing changes back to them, and define deletion handling separately.

HubSpot
Documented record · ✅ Supported
Rillet
Documented record · Incremental: ✅; historical: ✅; delete detection: ✅
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.

Compare integration approaches

Use HubSpot Company and Rillet Customer for the first pilot. Verify its identity and permitted direction, then add dependent records only when the acceptance checks pass.

Stacksync managed sync

Best fit
Two-way sync for supported objects. Choose the records, writable fields, and permissions for your workflow.
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: 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. 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 HubSpot and Rillet 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 Company / Customer, update direction, account tier, and related-record handling.

Custom API or workflow

Best fit
Consider when HubSpot and Rillet need a transformation, approval, or action outside a direct record sync.
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 HubSpot / Rillet 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

Customer sync test

Use writable fields from the connected accounts. Read values from read-only fields without writing changes back to them, and define deletion handling separately.

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

  1. Start with HubSpot Company and Rillet Customer. 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.

Customer sync test

Use writable fields from the connected accounts. Read values from read-only fields without writing changes back to them, and define deletion handling separately.

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

  1. Start with HubSpot Contact and Rillet Customer. 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.

Customer invoice sync test

Use writable fields from the connected accounts. Read values from read-only fields without writing changes back to them, and define deletion handling separately.

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

  1. Start with HubSpot Invoices and Rillet Invoice. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Resolve the customer or supplier, account codes, tax, currency, and accounting period before posting.
  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 posted invoice, a partial payment, tax rounding, and a closed accounting period. Compare financial totals within the same entity and currency.

If it fails: Determine whether a transaction posted before retrying. Follow the approved adjustment process for posted records.

Reconcile Rillet business records with HubSpot

Validate the selected objects and operations even where connector-level direction is documented.

Starting event: A finance-owned record in Rillet needs operational visibility through Contact or Company.

  1. Select Customer or Vendor with the correct legal entity, period, and currency.
  2. Define a reporting relationship in HubSpot; 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.

Company / Customer

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.

Contact / Customer

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.

Invoices / Invoice

Test case

Test a posted invoice, a partial payment, tax rounding, and a closed accounting period. Compare financial totals within the same entity and currency.

Expected result

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

Commerce Payments / Invoice Payment

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

Check that each connected account can read and write the chosen objects. Exercise both directions with a test record before enabling production changes.

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.
