Map the process first
Write down how a new inquiry arrives, who reviews it, what makes it qualified, and how it becomes an active customer. Include the cases that do not proceed.
Use that map to define the necessary stages and fields. Avoid adding a field simply because the software makes it available.
Choose realistic test cases
Prepare a new inquiry, an existing customer, a duplicate contact, a reassigned opportunity, and a closed or lost request. Walk through each with the people who will use the system.
Check whether the next action is obvious and whether the owner can find the information needed. Record workarounds that would create repeated manual effort.
Verify connections and plan limits
CRM products combine different sets of customer, sales, and marketing tools. Review the actual product and plan with providers such as Salesforce and HubSpot.
Confirm the integrations, API access, permissions, reporting, and automation features required for your process. A feature on a product homepage may belong to a different subscription.
Plan the data move
Inventory the source records, define duplicate rules, and decide which history must be retained. Test a representative sample before moving the full dataset.
Compare counts and important fields after the move. Confirm how your team will handle records that fail validation or need manual review.
Assign ongoing ownership
Name the person responsible for access, fields, stages, automations, and data quality. Include training and a change-request process in the rollout.
Review adoption through actual work: whether records are current, next steps are assigned, and reports answer useful questions. Software selection is only one part of making the process usable.
