What it is

You take messy spreadsheets, customer lists or simple databases and tidy them: removing duplicates, fixing errors, standardising formats and setting up simple structures. Many clients then keep you on for monthly upkeep.

Pick a niche, such as shops, tradespeople or clubs, and write a one-page service list with example day rates
Create a before-and-after sample using dummy data to show on a simple website or LinkedIn profile
Contact a handful of local businesses and offer a low-cost first clean-up in return for a testimonial

Who pays

Small businesses, shops, charities, clubs and trades firms with customer, stock or sales records that have got out of hand.

How it makes money

One-off clean-up projects priced per job or per day, plus a monthly retainer for regular updates, backups and reports.

Skills that help

Confident with Excel, Google Sheets or Airtable
Basic database skills such as Access or SQL
Careful attention to detail
Explaining things clearly to non-technical people
