About Technical and Integration

We do not require merchants to install server facilities as long as the information passed from merchants to us does NOT contain sensitive information (in fact, customers have to enter information such as credit card number, only in our payment page). Meanwhile, merchants are suggested to enhance levels of their web sites to provide maximum protection to their customers.


All sensitive information in our database is encrypted and protected behind a firewall system. Besides, at the browser level, is used.


Basically our payment services are independent of the e-commerce software you are using, as long as it provide the necessary parameters for us to process transactions.For merchant who is using MIVA Merchant or OS Commerce, PayDollar Cambodia provides a related API or scripts for merchant to connect our payment service platform. Merchant can also develop their own API to serve this purpose, and PayDollar Cambodia provides payment module of osCommerce and Zen-Cart to enable merchant integrate with PayDollar Cambodia Payment page from the open source shopping cart.


No. There are many factors that could affect the speed of a web site, like the power of the host server, quantity and size of images in the site, search methods and so on.


When a customer places an order at PayDollar Cambodia merchant's web site and selects the payment method, the customer will be redirected to our payment page for payment processing. All necessary parameters (e.g. transaction amount, order reference number, customer name) will be carried forward to the payment page at the same time. When the payment is processed, the results (either successful or failed) will be shown to the customer in another web page. Such information will also be fed to the designated web page of the merchant. for more sophisticated post-payment processing.


About Operation and Finance

In general, we do not handle information other than the parameters necessary for transaction processing. Parameters such as items purchased, model numbers, quantities, shipment addresses and so on, do not fall into this category. Basically merchants may refer to shopping carts for such information. Meanwhile, bundled services will be available to meet specific business needs.


Basically we accept payments of any amount. We also handle special business needs of merchants on a case-by-case basis.


When a customer pays with a credit card, details of the payment is passed to the bank for processing, which is completed in seconds. The result appears on the customer's web browser, and is passed to the merchant's site. Furthermore, the merchant may log in the PayDollar Cambodia Merchant Administration site any time to view the status of the payment and access hosts of other functions such as real-time void, refund,¡Ketc.. In any case, a summary of the payment is sent to the customer by email upon payment confirmation.


PayDollar Cambodia merchants may log in PayDollar Cambodia Merchant Administration site any time, and access various online reporting tools to track the credit card payment transactions and even download the report for accounting purpose.


Each PayDollar Cambodia merchants is entitled to accept payments from customers up to predetermined daily, monthly and per-transaction limits, which are different between merchants. Such limits are subject to adjustments according to business volumes, chargeback records and so on.


The availability of refund service depends on the service plan.

  • PayDollar Cambodia e-Commerce merchants should submit a completed "Refund Requisition Form" to us, stating details of the transaction to be refunded. There is no refund charges and refund charges will be returned to merchants
  • PayDollar Cambodia e-Commerce own-merchant-account customers should raise refund requests directly to our partner bank.

In any case, we monitor refund activity of merchants very closely. We are particularly concerned with excessive refunds since such may mean unsatisfactory service level (like late delivery or stock shortage).


A chargeback is the forced reversal of a transaction by the credit card issuing bank. Chargebacks take place when we receive notification from our partner bank that the cardholder's card issuing bank has received a dispute notice from the cardholder, whose card had been charged by our merchants. In certain cases defence is possible (e.g. order denial while delivery is completed indeed), given merchants are able to provide adequate evidence. Sometimes (for example, fraudulent card usage) a chargeback is made immediately. Please note that excessive chargebacks may result in service terms revision, service suspension or even termination.


The purpose of which is to prepare and maintain a sum for contingent chargeback requests. The rolling reserve is usually a percentage of monthly transactions (which ranges from 10% to 40%), which will be released to merchant after a short period of time (usually 60 days).


Fraudulent behavior online takes various forms from stolen card to system hacking. As an experienced payment service operator, we would like to suggest the following actions to minimize fraud.
  • Order details
    Merchants should urge customers to provide adequate information upon ordering, especially contact information of the customers. Make sure that the customer is a legitimate cardholder. More attention is required for suspicious orders (like remote delivery addresses or simultaneous multiple orders).
  • Free mail address
    Some fraudsters attempt to mask their identity by using a free mail addresses. While most users of free mail addresses are indeed legitimate, caution should be exercised for orders with free mail addresses, especially when this is the only way to contact the customers.
  • Out-of-norm orders
    Merchants should be wary of orders that falls outside usual ordering patterns, like bulk orders or purchases that greatly exceed the average transaction amount.
  • IP record
    Beware of orders made from odd locations (which are sometimes traceable with the IP addresses), especially where credit card fraud is more common.
  • Proof of delivery
    Get a signed proof of delivery or receipt if available upon retrieval request.
  • Return policy
    Merchants should devise and maintain clear, easy to understand and consistent product return policies to keep customers well informed

An effective way of minimizing losses due to fraudulence is to encourage customers to register as PayDollar Cambodia members. All bank accounts and credit cards of our members are authenticated, meaning that they are virtually "genuine" customers.

Merchant received payment by transfered. Normally PayDollar Cambodia e-Commerce merchants receive payments (less transaction commission) twice a month (on the 1st and 16th day of each month, to reimburse payments received between the 1st and 15th of the previous month, and that between the 16th and the end of the previous month respectively).


We do not deduct setup fees, monthly fees or marketing expenses from received payments of merchants. Such charges are billed to merchants separately. On the other hand, transaction commission, refund and chargebacks (if any) will be deducted from received payments before reimbursement.
