Estimates for a small start in Canada, not guarantees.

What it is

You fix messy customer lists, stock sheets and sales records: removing duplicates, standardizing formats, fixing errors and setting up simple rules so the data stays clean. You can also do regular monthly upkeep and backups.

Your first three steps

  1. Build a sample before-and-after clean-up using a made-up messy dataset to show potential clients
  2. Set a project price and a monthly retainer price, then write a one-page service description
  3. Contact five local businesses or your local chamber of commerce and offer a free quick data health check
Who pays

Small retailers, trades companies, clinics, non-profits and online shops whose records live in spreadsheets, CRMs or accounting software.

How it makes money

Fixed price per clean-up project, plus a monthly retainer for ongoing maintenance, backups and reporting.
