Practical guide · 01
Verify the partner in HubSpot’s own directory
HubSpot provides a solutions marketplace. Use it to check a current listing; a badge on an agency website alone does not explain what your proposed engagement includes.

Practical guide · 02
Migration success means usable records
A completed import is not acceptance. Review the relationships and workflows your team needs to use after migration.
- 1
Map
Define contact, company and opportunity fields. Record duplicates, missing values and source ownership.
- 2
Test
Use a bounded sample to check matching, permissions, associations and reporting. Keep a recoverable source export.
- 3
Accept
Walk through a real handoff and a reporting example. Document exceptions and who maintains the integration.
Practical guide · 03
Worked example: two records, one buying group
Fictional example: two contacts from the same business enter different campaigns. A partner should explain how the CRM keeps their commercial context together.
- Stage 101
Match
Confirm company association without merging distinct people. Record the basis of the match. - Stage 202
Route
Keep one account owner and role-specific contact histories. Prevent conflicting follow-ups. - Stage 303
Report
Show account progression without counting the same opportunity twice. Check the output against the underlying records.
Practical guide · 04
Audit before automating
Software cannot resolve a disputed operating definition.
Compare
Data
Check duplicates, associations and missing fields.
Process
Agree lifecycle stages, ownership and exceptions.
Practical guide · 05
Test permissions with the actual roles
Administrator access can hide an unusable workflow.
Compare
User
Test what the sales or service operator can see.
Owner
Test what the system owner can change and audit.
Practical guide · 06
Plan integration failure
A successful test needs an exception path.
Compare
Failure
Record retries, rejected records and alert ownership.
Recovery
Keep the source and a documented reconciliation route.
Practical guide · 07
Separate licensing from implementation
Partner fees and platform charges are different commitments.
Compare
Platform
Check the required products and current licensing terms.
Services
Check implementation, support and future change costs.
Practical guide · 08
Accept the workflow, not the slide deck
A handover should demonstrate real operation.
Compare
Walkthrough
Run an account from creation through routing and reporting.
Maintain
Document mappings, exceptions and the change owner.
