Failed cards quietly become churn
Declines retry automatically on a schedule that recovers most of them, before anyone has to make an awkward phone call.
Gyms & Fitness
Membership software for gyms, boxes and studios that bill every month
Recurring revenue, real retention numbers, and a front desk that is not chasing failed cards.
A gym lives or dies on recurring billing and churn. Black Belt CRM handles both properly: cards and ACH on any cycle, automatic retries when a payment fails, and retention reporting that tells you how long members actually last instead of just how many you have today.
What gets in the way
The parts that actually cost you money
You know your member count, not your churn rate
Cohort retention curves show how each intake month decays — so you can tell a bad month from a bad trend.
Personal training sits outside the system
Sessions, packages and one-to-one programs bill on the same account as membership, on the same ledger.
Retail is a separate spreadsheet
Apparel, supplements and gear sell through a real point of sale that posts to the same chart of accounts.
