Age-gate every transaction, reconcile both locations, run loyalty without losing the margin. Mainframe handles high-risk compatible processing, compliance-ready receipts, and the text blast that brings them back next week.
Build my shop →Two registers, two back rooms, one source of truth.
Three workflow chains built for regulated inventory and walk-in volume.
ID hits the reader, Mainframe confirms age, logs the verification to the audit trail, rings the sale. No gray area, no pen-and-paper log book.
Store A sells the last box, Store B's order is already queued. No double-buying, no "we're out, try the other location."
Every verified customer lands on the loyalty list. Mainframe times the follow-up to their refill cycle — not a generic weekly blast.
Age-gated retail needs high-risk compatible processors. Mainframe wires them in.
Tell Mainframe what you sell. It builds the back office.
