Customer Retention for Small Businesses

Keep more of the customers you already have with simple maths, a better first month, honest listening and fair, respectful programmes.

Most small businesses track new sales closely and pay far less attention to who comes back. This course shows you how to put a value on a returning customer, measure retention with correct formulas and cohort tables, listen through surveys and support conversations, and run loyalty, win-back and cancellation processes that customers find fair. You finish with a one-hour monthly retention review that runs on a spreadsheet.

What you will be able to do

  • Estimate customer lifetime value and acquisition cost for your business, and use them to decide what a returning customer is worth
  • Design a first-30-day onboarding plan built around one clear first-value milestone
  • Calculate churn, retention and repeat purchase rates correctly, and build and read a monthly cohort table
  • Collect feedback with short surveys and tagged support conversations, and set response targets, a tone guide and saved replies for support
  • Run simple loyalty, referral and win-back programmes and a fair cancellation flow within consent rules, and review them in one monthly meeting

Who it is for

  • Owners and managers of small shops, studios, service firms and online stores who want more repeat customers
  • Founders of small subscription or membership businesses who need to understand and reduce churn
  • Marketing, customer service or operations staff asked to “improve retention” without a dedicated analyst

Before you start

  • A business, side business or team with at least a few months of customer or order history
  • A spreadsheet tool; no specialist software is needed
