Why Retention Beats Acquisition for Most Small Businesses

The arithmetic of repeat custom, and the low-cost retention habits that outperform most advertising budgets.

The arithmetic

Winning a new customer typically costs several times more than keeping an existing one. A 5% improvement in retention compounds through repeat purchases and referrals in a way a single new sale does not.

Habits that cost nothing

Most retention is operational, not marketing.

  • Answer the phone and reply to email the same day
  • Tell customers when something will be late, before they ask
  • Fix mistakes fast and without argument
  • Ask for feedback and visibly act on it

Measure it

Track repeat purchase rate quarterly. If you cannot tell whether customers come back, you cannot tell whether anything you do is working.
