On market mornings, children played around the door while adults sipped coffee and compared receipts like trading cards. Potogas’s verified stamp had become a small talisman, an everyday emblem of being seen. And in San Luis Potosí, where history tucked itself into every corner, Potogas kept adding new lines to the town’s ledger: simple transactions turned into stories of acknowledgment, the ordinary elevated by verification into proof that people belonged.
One evening, a power outage swept the block into darkness. The terminal’s backup battery kept blinking, then went still. Customers worried about lost records and lost luck. Mariana lit a candle, closed the shop for a minute, and returned with a ledger. She began to write—neat, inked entries with names, items, and promise: “Factura to be generated when power returns.” The gesture felt old-world and radical at once. People left with handwritten proof that someone had seen their purchase and cared.
Years later, when the neighborhood changed—new cafés with sleek terminals, an app that promised instant invoices—Potogas remained. Its terminal was updated, its processes modernized, but the same ritual held: patrons arriving, receipts printed, a quiet verification that their daily lives mattered. Mariana would joke that the facturación system kept everyone honest, but really she knew the truth: verification wasn't just about numbers or taxes—it was about recognizing people, one verified factura at a time.
