I will fix broken hubspot salesforce two way sync duplicate contacts notion integration
CRM AND AUTOMATION EXPERT
About this Gig
Your HubSpot and Salesforce stop agreeing with each other.
A contact updates in one system and never shows up in the other, or worse, the sync creates a second copy of the same contact every time it runs. Sales and marketing end up working from two different truths.
I diagnose and fix broken two-way sync between HubSpot and Salesforce, then clean up the duplicate contacts the broken sync already created.
You get a full sync audit to find exactly where records are breaking, the root cause fixed so data flows correctly both ways, existing duplicates merged and cleaned, and a retest to confirm both CRMs finally match.

FAQ
Primary outcome
Problem: Your HubSpot and Salesforce show different contact data because the sync between them silently broke, before deals started slipping away. Result: You get one working two-way sync, existing duplicates merged, and both CRMs finally showing the same clean data.
Niche buyer type
Problem: Sales teams in Salesforce and marketing teams in HubSpot end up chasing two completely different versions of the same contact record now. Result: I rebuild the sync mapping so both teams see identical, up to date records in real time without manual checking.
Premium justification
Problem: A basic fix solves today's sync error but a new field mapping or app update can quietly break the connection all at once next month again. Result: Premium adds sync monitoring and duplicate prevention so both CRMs stay fully aligned long after delivery ends.
Technical detail
Problem: You want to know exactly why the sync broke and how duplicates got created before trusting a fix that touches your live customer records directly. Result: I document the exact failure point, the merge logic used, and a Loom recording showing the retest live.
Niche variations
Problem: Some businesses have years of accumulated duplicate contacts from the sync that has been failing quietly in the background for a long time. Result: I merge every duplicate found across both CRMs and rebuild the sync so records stop duplicating going forward.
