How to replace dealership spreadsheets and duplicate entry

What to check before you decide

For each one, find the source of truth. Which system should own this data?

A price should live in the inventory system, a customer in the CRM or DMS, a deal in the DMS. Then see whether a connection can carry the data without typing.

Ask the vendors what integrations exist, which direction they run, how often they sync, and what they cost. An export that someone uploads every Friday is a spreadsheet by another name.

Replace in steps. Automate one flow, run it beside the old process for a month and compare results.

Keep an exception path: a clear way to handle a record that does not fit. Write the rules down so a tool, and a new employee, can follow them.

Protect the controls. A spreadsheet often hides a check that a person performs, such as reviewing a commission against a deal. Make sure the replacement keeps it.

Finally, measure. Track hours saved, errors found and rework, and review the list every quarter. New spreadsheets appear wherever a process has a gap.

Keep the old spreadsheet read-only for a month after replacing it. If someone goes back to it, find out why.

Usually the new process is missing a field or an exception. Fix it, then archive the file with a note on where the data now lives.

Expect resistance from the person who built the spreadsheet, who often holds knowledge the new process will need, so involve that person early, credit the work and let them help design the replacement instead of treating the old file as a mistake to be removed.
