Company reporting workflow

Object-specific availability and field permissions determine this mapping. Use the restrictions shown for each record type.

Starting eventA change involving the proposed company table in BigQuery or HubSpot Company needs a defined result in the other system.

  1. Start with the proposed company table in BigQuery and HubSpot Company. Use the record-matching and field-ownership rules from your mapping worksheet.

  2. Resolve parent organizations, business units, and currency references before dependent 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 verifyUse two organizations with similar names and one with multiple business units. Verify that an update reaches the intended entity only.

Why teams connect BigQuery and HubSpot

Put your BigQuery and HubSpot 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 BigQuery and HubSpot workflow to test, define what success looks like, and decide who handles failed updates.

  • Build board-level pipeline dashboards on BigQuery instead of HubSpot's native reports.

  • Enrich HubSpot Contacts with attributes calculated from warehouse Tables, kept current by two-way sync.

  • Analyze Ticket volume against Deal size in BigQuery to price support into renewals.

What records can you sync?

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

Compare integration approaches

Use BigQuery Proposed company table in BigQuery (choose its name) and HubSpot Company 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: Retain the source company ID and the destination customer/company ID. Separate legal entities, subsidiaries, and business units; a shared name or web domain is 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 BigQuery and HubSpot 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 Proposed company table in BigQuery (choose its name) / Company, update direction, account tier, and related-record handling.

Custom API or workflow

Best fit
Consider when BigQuery and HubSpot 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.

File or scheduled snapshot

Best fit
Consider for a one-time BigQuery / HubSpot 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

Company reporting workflow

Object-specific availability and field permissions determine this mapping. Use the restrictions shown for each record type.

Starting event: A change to the selected Proposed company table in BigQuery (choose its name) or Company record needs a defined result in the other system.

  1. Start with BigQuery Proposed company table in BigQuery (choose its name) and HubSpot Company. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Resolve parent organizations, business units, and currency references before dependent 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: Use two organizations with similar names and one with multiple business units. Verify that an update reaches the intended entity only.

If it fails: Repair the cross-system ID relationship before retrying dependent records; do not merge companies solely to remove a sync error.

Contact reporting workflow

Object-specific availability and field permissions determine this mapping. Use the restrictions shown for each record type.

Starting event: A change to the selected Proposed contact table in BigQuery (choose its name) or Contact record needs a defined result in the other system.

  1. Start with BigQuery Proposed contact table in BigQuery (choose its name) and HubSpot Contact. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Resolve the organization relationship and any owner or consent references required by the destination.
  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 email change, two records sharing an email, and a person associated with multiple organizations.

If it fails: Hold ambiguous matches for review and reconcile the person ID before retrying; preserve the consent decision already recorded by its owner.

Deal or opportunity reporting workflow

Object-specific availability and field permissions determine this mapping. Use the restrictions shown for each record type.

Starting event: A change to the selected Proposed deal or opportunity table in BigQuery (choose its name) or Deal record needs a defined result in the other system.

  1. Start with BigQuery Proposed deal or opportunity table in BigQuery (choose its name) and HubSpot Deal. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Map the customer and sales pipeline before the opportunity; map stage values deliberately.
  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 reopened won deal, a stage with no destination equivalent, and an amount using a different currency.

If it fails: Suspend downstream creation for a rejected deal and review whether an order already exists before retrying.

Define an explicit handoff between BigQuery and HubSpot

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

Starting event: A business event involving a selected business dataset needs a defined response involving Contact or Company.

  1. Document what the source event means and which destination record or action should respond. A similar name does not establish a shared entity.
  2. Retain separate IDs and choose whether the destination is a report, a new work item, or a change to an existing record.
  3. Assign an approval owner and a duplicate-detection rule before running an action. Use a custom workflow only after its endpoint support is confirmed.

Expected result: An example input has an unambiguous destination and expected result; repeated delivery produces only the intended change.

If it fails: Resolve missing identity or ambiguous business meaning before retrying; route unsupported operations to the implementation owner.

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.

Proposed company table in BigQuery (choose its name) / Company

Test case

Use two organizations with similar names and one with multiple business units. Verify that an update reaches the intended entity only.

Expected result

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

Proposed contact table in BigQuery (choose its name) / Contact

Test case

Test an email change, two records sharing an email, and a person associated with multiple organizations.

Expected result

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

Proposed deal or opportunity table in BigQuery (choose its name) / Deal

Test case

Test a reopened won deal, a stage with no destination equivalent, and an amount using a different currency.

Expected result

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

Proposed support case or ticket table in BigQuery (choose its name) / Ticket

Test case

Test a merged ticket, a private note, a reopened case, and an attachment with restricted access.

Expected result

The expected support case or ticket 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.

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 company change

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.
