Move from sales spreadsheets without losing context.

1. Set a goal before selecting tools

1. Assign a transition owner. One person aligns data, deadlines and decisions.
2. Describe the problem you are solving. For example: quotes have no owner, follow-up is overdue or the team cannot see what was agreed.
3. Set the measurable sign of progress. Track the completeness of owners, deadlines and next steps, rather than an invented overall result.

2. Prepare data

1. Save source Excel file as backup.
2. Separate companies, contacts, opportunities and activities.
3. Remove obvious duplicates, but keep track of the decision.
4. Check mandatory fields: name, owner, phase, value, deadline and next step.
5. Do not import private notes and data without a clear business purpose.

3. Define sales flow

1. Use a small number of clearly different stages.
2. For each phase, write the condition of entry and exit.
3. Decide who can change the owner, value and status.
4. Determine when an opportunity has been won, lost or archived.

4. Do a test migration

1. First, import a small representative sample.
2. Check local letters, dates, currencies and owners.
3. Compare the number of rows and key values with the source.
4. Only after the check do full import.

5. Prepare the team

1. Everyone knows where to find their daily work.
2. Set a minimum rule: no active opportunity without owner, deadline and next step.
3. Tie training to a real process, not to tour each menu.
4. In the first weeks, quickly correct unclear fields and duplicates.

6. Verify the transition

1. New communication and quotes arrive with the correct customer record.
2. The manager may see open opportunities and standstills without additional table.
3. The operational team gets the deal, the commitment and the deadline without rewriting.
4. Excel remains an archive until it is confirmed that the data are complete and available.
