CRM Migration

Manual Spreadsheet to CRM Transition

Move a team running their pipeline in a shared spreadsheet onto a real CRM, mapping columns to fields, deduping on the way in, and rebuilding the stage logic, so they gain ownership and follow-up without losing their history.

Outcome
signals

These are the real outcome statements attached to this HMX CRM case study.

history preserved: no data lost in the move
deduped on import: spreadsheet duplicates cleaned
real ownership: leads owned, not in a shared cell
follow-up gained: reminders the sheet never had

Problem

The operating gap

The team tracks leads in a spreadsheet that has quietly become the system of record: no real ownership, no reminders, version conflicts, and stages that are just a colored column. They've outgrown it but fear losing data and history in a move.

Build

What gets built

Map spreadsheet columns to CRM fields, clean and dedupe the data in staging, design the pipeline stages from how the sheet's status column was really used, import with source/owner intact, and add the follow-up and ownership the spreadsheet never had.

steps

Manual Spreadsheet to CRM Transition uses a CRM operating layer for CRM Systems. Move a team running their pipeline in a shared spreadsheet onto a real CRM, mapping columns to fields, deduping on the way in, and rebuilding the s... The architecture connects every spreadsheet column to, supabase / postgres staging, gohighlevel or pipedrive, and owner follow-up with an explicit control path.

01Map every spreadsheet column to a target CRM field and flag what to drop or split
02Clean and dedupe the data in a staging table so only good records get imported
03Design pipeline stages from how the sheet's status column was actually used in practice
04Import contacts and deals with source, owner, and history fields preserved
05Add the ownership, reminders, and follow-up tasks the spreadsheet never supported
06Reconcile counts against the sheet and run the team through the new pipeline before retiring it

basis

Build a CRM with the same traceability

The intake starts with lead sources, stages, and follow-up rules so the scope stays honest.
