HubSpot ERP Integrations
An ERP integration fails for one reason more than any other, and it is not technical. Two systems end up writing the same field, nobody decided which one wins, and the number a salesperson quotes stops matching the number finance invoices.
The ERP owns money. It owns the invoice, the recognised revenue, the payment date, the credit position and the tax determination, and it owns them because it is the system an auditor will be shown. HubSpot owns the relationship: who is being spoken to, what was promised, which stage the work is at and why the last attempt was lost.
Almost every difficult question in this category resolves once that line is drawn per field rather than per system.
15 systems in this category, 8 of them documented in a published case study.
What an ERP integration is actually deciding
Three questions come before any connector is chosen, and the answers hold whichever one is selected.
Identity first. No two commercial systems share an identifier space, so a customer in the ERP and a company in HubSpot are the same organisation only because something asserts it. Where that assertion is a name match, it will eventually match the wrong one.
Then ownership, field by field. A value written by both sides without a stated winner is a value that will disagree, and the disagreement surfaces during a commercial conversation rather than during a data review.
Then observability. The integration failures that cost trust are the silent ones: an expired credential or a paused schedule, where records stop moving and both systems continue reporting themselves healthy.

Common Questions
Frequently Asked Questions
Frequently, and it is the first thing assessed. Where the packaged connector's assumptions match the business it costs least, is maintained by the vendor, and fails in ways thousands of other portals have already reported. Custom work is warranted where the object model cannot be expressed in it: project-level costing, a regulatory constraint on where data may travel, or a second system writing to the same field.
Both, for different fields on the same organisation. Legal entity, billing address, payment terms and credit status belong to the ERP because finance is accountable for them. Owner, lifecycle stage, source and every activity belong to HubSpot. What cannot hold is one field written by both without a conflict policy.
No, and syncing it wholesale is the commonest way to make a portal unusable. The useful question is which fields a commercial decision depends on. An invoice status and a payment date change how a renewal conversation runs; a general ledger account code does not.
A field added on one side that nobody mapped, a credential that expired without an alert, and volume growth that pushed a sync past an API limit it was never measured against. All three are prevented by monitoring rather than by design.
