Tender

Sell digital gift cards for your business the way GiftUp or Square do it, except the program is yours. Buyers pay through your own Stripe account, the recipient gets a beautiful card by email on the day the buyer picks, and your staff redeem against the balance at the counter. No platform percentage on every card, no monthly gift card fee, no one between you and your customer.

Not a starter scaffold, a finished product. The seed ships a working demo shop with four cards in real states: one fully spent across three visits, one partially redeemed with a voided mis-ring, one scheduled for a future delivery date, and one comp card, so the console, the counter, and the card page all show life on first paint. A verified Stripe webhook activates each card exactly once, a receipt goes to the buyer, and a poll-then-reveal success page never leaves anyone at a dead end.

The whole loop is built in. A server-rendered buy page with preset and custom amounts, a personal note, and a live CSS card preview. A printable card page the recipient keeps forever, with balance and history. A PIN-gated counter surface where staff look cards up, charge them with race-safe balance math, and void the last charge with a reason; wrong PINs are rate-limited in plain SQL. A calm dark console tracks outstanding liability, sold and redeemed totals, comp cards, and a month-by-month reconciliation view your accountant will actually like.

Source-available. Fork it onto your own subdomain, edit any file, own it forever. AGENTS.md ships ten extension recipes (expiry policies where legal, promo bonuses like pay 50 get 60, physical card import, multi-location PINs, top-up links, a monthly liability email, refund handling) so you or your AI tool can grow it into exactly the gift card program your shop needs. Free to fork and self-host on Hatchable.
