FitMetrics automatically matches Stripe and Whop payments to Trainerize clients by email address. When the purchase email matches the Trainerize client email, the link happens instantly.
But sometimes emails don't match — here's how to fix it.
How to Spot Unmatched Payments
In the Payments Tracker, unmatched clients show:
A link icon (S for Stripe, W for Whop) next to their name in the Status column
Status shows "No Subscription" even though you know they're paying
You can also filter the table by Status → No Subscription to find all unmatched clients quickly.
How to Link a Payment
Find the unmatched client in the Payments Tracker
Click the link icon (S or W) next to their name
A Search & Link dialog opens
Start typing the client's name or email — FitMetrics searches your Stripe customers or Whop members in real time
Select the correct match
Click Link
Once linked:
All past payments from that customer appear immediately
All future payments will be tracked automatically
The link is permanent — you only need to do this once per client
Why Emails Don't Match
Common reasons:
Client used a different email for Stripe/Whop than for Trainerize
Client paid with a spouse's card (different email on the payment)
Client has multiple email addresses
Stripe customer was created before the client joined Trainerize
Important Notes
You do NOT need to change emails or re-charge clients — just link them
Linking works for both Stripe and Whop
If you have multiple Stripe accounts, make sure you're viewing the correct account (use the account selector dropdown)
FitMetrics is read-only — linking only connects data, it does not create or modify any payments
