Cobrix sends friendly payment reminders by email, shows each customer what they owe and how to pay, and tells you who is running late. You sell, Cobrix follows up.

Nothing to install and no spreadsheets to chase. This is the first version we are validating.
Add your customers and their balances by hand or from a spreadsheet.
Polite email reminders, with limits on timing and frequency.
Each one sees their own statement with your payment details: Zelle, Venmo, ACH, a card link or whatever you already use.

A clear dashboard of what you are owed, what you have collected and who is worth a nudge today.

A clear, friendly reminder protects the relationship with your customer and helps you get paid on time.

Yes, anytime from your Hotmart account. Cancel during the trial and you are not charged; after that you keep access until the end of the period you paid for.
We use it only to tell you about the launch and to understand what small businesses need. We don't sell it. You can ask to see, correct or delete it by writing to contato@cobrix.site.
