Gift Card and Voucher Balance Register with Expiry and Redemption Log

Gift Card and Voucher Balance Register is an offline app (one HTML file in a zip) for a business that sells or gives out gift cards on paper or by message. Each card gets a number, a value, an optional expiry and a holder. Every use is written to a log, so the balance of any card is one search away, and the total you still owe in unused gift cards is always on the front page.

The problem it removes: A card is sold, used in two visits, then used a third time for more than it had left, because nobody wrote down the balance. A customer returns after a year and no one knows if the card was ever used. At the end of the month nobody can say how much gift card money is still out there. This app keeps one balance per card and refuses to redeem more than it holds.

What is inside:

• Cards with an automatic number, kind (gift card, promo voucher, store credit), value, how it was paid, holder and phone
• Redemption log with a quick Redeem form: a redemption larger than the balance is refused, and so is one before the card was issued
• Expiry from a validity period you set, or a date you enter for one card, with Expiring soon and Expired lists
• A card that has expired is refused unless you tick that you honoured it, so exceptions are written down
• Top-ups and write-offs, balance of each card, and the total owed on paid cards separated from free promo vouchers
• Printable card (A6) and a balance statement showing every use, plus a list of balances as of today
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: owners of salons, cafes, florists, boutiques, studios and shops who sell gift cards or give store credit and today track them in a notebook or a chat.

What it is NOT: It does not connect to a till or card machine, does not stop a card being used at another branch, and has no online redemption. It does not say how long a gift card must stay valid: the validity period is a number you choose, and any rule about gift card expiry is something to check with your adviser. It is not accounting advice. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (123 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 792 calculated values (25 randomised rows plus the example data) with 0 mismatches. Safari engine (WebKit): smoke test passed; Firefox: could not be launched. Not tested: Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
