This guide provides a comprehensive overview of how to set up your customers to accept payments through Ordermentum. It covers the payment methods supported, how to add and manage payment details, and how to handle trade accounts and payment transactions.
Introduction
Ordermentum serves as a secure payment gateway for your customers, partnering with Zai to process and store payments safely.
Customers can use various payment methods — including credit/debit cards, direct debit, and trade accounts — to pay for their orders through Ordermentum.
Accepted Payment Methods
Ordermentum supports the following payment options:
💳 Credit/Debit Cards
Visa
Mastercard

🤝 Trade Accounts
Finstro
Setting Up a Customer to Accept Payments
Follow these steps to configure your customer’s payment settings:
Go to Customer Details → Payment & Trading Terms.
Select the payment methods you would like your customer to use.
Please Note:
Customers without an "Other" payment method will be required to enter a payment method before placing an order.
Customers can apply for and pay with trade accounts from any supplier that accepts debit/credit cards.
Only invoices created after payment details have been added will be automatically paid according to the customer's trading terms.
Adding Customer Payment Details
To add your customer’s payment information:
Make sure Credit/Debit Card is enabled under Available Payment Methods.
Click Add Card Details.
Follow the prompts to securely add your customer’s payment details.
Important:
Suppliers cannot add Direct Debit details for customers due to service terms and conditions.
For more information, please contact our support team at support@ordermentum.com.
Managing Trade Accounts
Some customers may apply for and pay with a Trade Account offered by an Ordermentum partner.
This option allows you to get paid upfront while your customers pay on agreed terms with their Trade Account provider. Customers can use their Trade Account to pay any supplier on Ordermentum that accepts debit/credit cards.
Please Note:
To pay with a Trade Account, the customer's trading terms must be set to "Pay on Place" or have funds held upfront.
Charging Now for Unpaid Invoices
To instantly attempt payment for an unpaid invoice:
Open the Order Details.
If payment details are stored in Ordermentum, the Charge Now button will be available.
Click Charge Now to immediately attempt to process and pay the invoice.
Applying Credit Notes
If the customer has an eligible credit note from the same supplier, it will be automatically applied during payment processing when you click Charge Now. You do not need to manually apply the credit note first.
For the credit note to apply automatically:
The credit note must be in Issued status and not locked
The invoice total must be greater than the credit note amount (at least $1.00 more)
The customer's payment method must be Credit/Debit Card or Direct Debit
If the credit note amount equals or exceeds the invoice total, it will not apply and will remain available for a future qualifying invoice.
What happens if a payment fails?
If the Charge Now attempt is unsuccessful, the invoice will remain unpaid, and you will see a failed payment notification. Common reasons for failure include:
Insufficient funds on the customer's card or bank account
Expired or invalid card details
The customer's bank declined the transaction
If payment fails, you can:
Ask the customer to update their payment details, then click Charge Now again
Adjust the invoice due date to give the customer time to resolve the issue
Contact our support team if the failure reason is unclear
Note: A failed payment may cause any associated credit notes to become locked. If a credit note is not applying as expected after a previous failed payment, contact support to have it unlocked.
Changing the Due Date of a Payment
To change the due date or automatic transaction date of a payment:
Click Edit Order.
Modify the Due Date field. This update will adjust the day the charge is automatically attempted.
Bank Statement Descriptors
When your customers pay through Ordermentum, the description that appears on their bank statement is called a merchant descriptor. It is set by Ordermentum's payment partner and is based on your registered supplier name in Ordermentum.
Payment Method | Bank Statement Format |
Mastercard / Visa | ZAI*OM SUPPLIERSHORTNAME-OMI### |
American Express | ORDERMENTUM (while pending), then ZAI*OM SUPPLIERSHORTNAME-OMI### (once completed) |
Direct Debit | SUPPLIERSHORTNAME-OMI### |
If multiple invoices are charged in a single payment, an asterisk (*) is added at the end of the descriptor.
The SUPPLIERSHORTNAME portion is based on your registered supplier name in Ordermentum and should be a maximum of 9 characters.
To request a bank statement descriptor update, contact our support team. This is an internal process and cannot be changed directly within your Ordermentum settings.
