* **Flexible Checkout Options**\
  Generate payment links or QR codes that customers can scan, facilitating quick and convenient sign-ups and approvals for installment payments in-store.
* **Branch Management**\
  Easily register and manage your physical branches or store locations, enabling location-specific transactions.
