Vouchers

Issue vouchers your way — single, batch, store-locked

Run your own voucher programs: single-use or batch, delivered by WhatsApp, email, or as downloadable PDFs (with QR/barcode). Choose exactly where a voucher can be spent: pick approved businesses from the registry and lock usage to those stores only.

  • Targeted spend: groceries to supermarkets, materials to hardware networks, airtime to carriers you select.
  • Eliminate misuse: ring-fence funds for their intended purpose.
  • Granular rules: amount, currency, expiry, allowed merchants, daily/category caps, audit trail.
