Before Black Friday: a checkout that dies costs you the month
Black Friday 2025 falls on 28 November. In Costa Rica and Mexico the peak is not only that Friday: it is the Buen Fin–Cyber Monday stretch. October is when you load for real: 3-D Secure, acquirer limits, “paid” webhooks, and inventory that cannot live in a shared spreadsheet.
What fails on the 28th was not invented on the 28th. It was invented when collection was a SINPE link in a WhatsApp status and the “system” was the manager’s memory. At 37 days you can still connect the gateway to the order. At 3 days, you cannot.
October rehearsal, not November heroics
- A live test payment (minimum amount) and the order marked paid with no one in the loop.
- Stock caps per SKU. Selling what you do not have is worse than not advertising.
- Hosting and cache: the homepage GIF cannot take down checkout.
- The store and the WhatsApp channel must not duplicate the same order.
If volume goes to WhatsApp, utility templates are cheaper than a marketing blast. That is designed with Respond.io, not on Friday afternoon.
Black Friday does not forgive the rail that never got turned on in October.
Quote collection and peak load now. Creative can wait a week. The acquirer is not contracted on the 27th.
