A sales rep moves a deal to "Proposal Sent" in HubSpot. Three days later, someone checks the ConnectWise Opportunity for that same deal and it still says "Qualifying." Nobody changed it back. It just never moved, because whatever sync is running between the two platforms either does not touch deal stage at all, or it does and something upstream silently failed.
This is not a hypothetical. An MSP describing their own setup on r/msp put it plainly:
"Tired of having two systems to look at pipeline and not matching because sales enters something in HS that doesn't match what ends up in the CW Opp."
Two systems, two truths, and no way to tell which one is current without opening both and comparing by eye. Multiply that across every open deal in the pipeline and you get a sales team that has quietly stopped trusting either platform, which defeats the entire point of having a CRM in the first place.
The trap underneath it
The same MSP raised the issue that usually surfaces once someone tries to fix this properly: source of truth. If HubSpot and ConnectWise can both write to the same field, which one wins when they disagree? They said it directly:
"Was worried about duplication issues, specifying source of truth - but also allow for certain data to update bi-directionally"
That is the real requirement, and it is harder than it sounds. Most "bidirectional sync" tools are actually all-or-nothing: either HubSpot owns a field or ConnectWise does, for every record, all the time. That works until the one time you genuinely need the other side to win, and there is no mechanism for it.
What field-level conflict resolution actually means
Bidirectional deal sync should not mean "last write wins" and it should not mean "pick one platform as boss forever." It means each field gets its own resolution rule, evaluated at the moment both sides have changed: if only one side changed since the last sync, that side wins outright. If both changed, the more recent timestamp wins, and if a timestamp is missing entirely, an unknown source falls back to now while an unknown target falls back to no timestamp at all, so an unresolvable case defaults to the side that actually reported when it changed, not to whichever platform happens to run its poll first.
That is exactly what HubConnector's conflict resolution log records: every field-level decision, on every record, with which side won and why, so when a rep asks "why does this deal say something different in ConnectWise," the answer is a log entry, not a guess.
If your team is tired of reconciling two pipelines by hand, HubConnector is opening a waitlist at hubconnector.io.
