HubSpot uses associations and properties to connect marketing, sales and service activity. A contact may exist independently, belong to a company, participate in a deal and appear in lists or workflows. Those relationships must be planned before bulk upload.
Custom properties require more than matching a column name. The target may accept dropdown options, dates, numbers, multi-select values or owner references. Unsupported labels and invalid formats are isolated before import rather than forced into the nearest-looking option.
Some properties can affect automation, lead routing, lifecycle reporting or communication. The client identifies workflow-sensitive fields and decides whether production users may update them. Routine record entry remains separate from marketing or sales strategy.
