Spreadsheets are where most charities start, and there is no shame in it. A well-kept spreadsheet has carried many organisations a long way. But there comes a point — usually around Gift Aid, reporting, or sheer volume — where they quietly start to hold the charity back.
Migrating to a CRM is far less daunting than it looks if you treat it as a project with a few clear stages, rather than a single risky switch flicked one weekend. The teams that struggle are almost always the ones who tried to do it all at once.
Know when you’ve outgrown spreadsheets
The signs are familiar, and if several ring true, the cost of staying is now higher than the cost of moving:
- Duplicate donor records you keep tripping over
- Gift Aid claims assembled by hand, line by line
- No reliable way to see a single donor’s full history
- Reports that take days rather than minutes
- Only one person who really understands “the sheet”
When the spreadsheet has become a part-time job, it has stopped being free.
Clean before you move
Migration is the best opportunity you will ever get to fix your data — so do not carry the mess across. Deduplicate donors, standardise addresses and dates, and resolve obvious errors first. Moving bad data into a good system just gives you bad data in a more expensive interface.
Map your fields deliberately
Decide exactly where each spreadsheet column lands in the CRM before you import anything. Pay particular attention to the fields that are easy to lose and painful to reconstruct:
- Giving history — every gift, with its date and fund
- Communication preferences and consent — your lawful basis, per the ICO’s guidance
- Gift Aid declarations — and the claim history attached to them
Preserve Gift Aid history
Gift Aid records must be retained to defend claims under HMRC inspection, so your migration plan has to carry declarations and claim history intact — not just current balances. HMRC’s Charities Online framework assumes you can produce the paper trail on request.
This is where a purpose-built, HMRC-listed platform earns its place: it understands what needs to survive the move, and keeps declarations linked to the donations they cover.
Run a parallel period
Do not flip the switch overnight. Run the CRM alongside your spreadsheets for a short, defined period, reconcile the two, and only retire the spreadsheets once the numbers match.
A parallel run is the cheapest insurance you can buy against a bad cutover.
Bring your team with you
A migration succeeds or fails on adoption. Train the people who will use the system daily, agree how records are created and updated, and give everyone a single source of truth. The platform choice itself is worth getting right first — see our charity CRM buyer’s guide and our post on choosing a CRM as a trustee — and once live, the same clean data unlocks better donor retention.
