Prepayment of the order OpenCart

Prepayment is a flexible module for OpenCart that allows you to charge customers only a portion of the order amount at checkout. It's an ideal solution for stores with high-ticket items, custom production, custom delivery, or partial payment options.

The module adds a separate "Prepayment" line item to the order total and automatically recalculates the final payment amount—the buyer pays only the portion you set, not the entire amount.

Key Features

• Calculation of advance payment as a percentage or a fixed amount.
• Setting a minimum prepayment amount.
• Selecting which results to base the prepayment on:
  • cost of goods,
  • delivery,
  • taxes,
  • discounts and other "Total" modules.
• Restrictions on delivery methods.
• Restriction on payment methods.
• Support for manual specification of delivery codes.
• Flexible logic for reducing or maintaining the minimum threshold.
• Separate setting of sorting order in the list of totals.

How the module works

You set up the terms—for example, taking a 30% prepayment for courier delivery and card payments. When placing an order, the module:

1. Checks the selected delivery method.
2. Checks the payment method.
3. Defines the basis for calculation.
4. Calculates the amount of the advance payment.
5. Replaces the total order amount with the prepayment amount.

As a result, the client pays only the established part.

✔ Reduced risk of failures
✔ Protection against unpaid orders
✔ Convenient handling of expensive and customized goods
✔ Full control over calculation logic

Where it is especially useful

• Furniture and custom-made goods
• Building materials
• Wholesale sales
• Long-term delivery items
• Online stores with a high average order value

Recommendation: Place the module last in the "Total" list so that the calculation is performed correctly after all discounts and surcharges.

The module easily integrates into the standard OpenCart system, doesn't overload your website, and provides you with a flexible financial risk management tool. Simple setup provides maximum control over payments.
