STX Desktop: Merchant Account Setup

New Account

STX can process credit cards and debit cards directly through the software with the help of a high-speed Internet connection. You must have a First Data EMPS merchant account and must also be licensed for the STX credit card processing module before you will be allowed to process credit cards electronically through STX. Whether you wish to process your payments using a single merchant account for the entire company, individual employee merchant accounts, or an online merchant account for use with Online Services, STX can be set up to accommodate your needs.

In order to utilize STX credit card processing, you must first obtain the following: 

  1. A Magnetic USB Swipe Reader for each computer that will be processing credit cards and at least one receipt printer. Please refer to the Product Specifications Chart at the end of this document. 

  2. The latest version of STX software to support electronic credit card processing (STX 3.0 v269 or higher), which is also PCI compliant. 

  3. A stable, high-speed Internet connection via Ethernet to each computer doing the electronic credit card processing. 

For information on credit card processing through STX and STX Online Services, please contact our Sales team at 800.766.4778, or by emailing sales@stxsoftware.com.

Once you have acquired your new merchant credentials, your First Data EMPS  consultant should send you an email letting you know the account has been approved. This email contains all of your account information, as well as the Merchant ID and Merchant Key used within the STX software. 

Setting Up STX (Receipt Options)

Go to Setup: General: Merchant. NOTE: You will probably need to log in as OWNER to see this area, unless you have given an employee security permission to see this screen.

Check Discount Details and/or Discount Summary to have the information printed on each receipt, not just the electronic payments receipts. 

Setting Up STX (Company Merchant Account)

Enter the appropriate information into the Instore Merchant Account area.

To have a Tip Line included on the electronic payments receipts, check the Receipts Include checkbox.

Set the Processor popup menu to Tempus.  

Leave this screen open and refer to the initial email from your First Data EMPS  consultant containing the Online Merchant ID and Merchant Key.

NOTE: The following TEST information is used to show how the formatting of the information will be similar to your own merchant information, and in no way reflects your company merchant information. 

Highlight the Merchant ID contained in the email. 

Go to the Edit menu to select the Copy option.

In STX, click inside the Merchant ID field and go to the Edit menu to select Paste.

This will place the Merchant ID information into the Merchant ID field in STX.

Go back to the initial email from your First Data EMPS consultant containing the Merchant ID and Merchant Key. 

Highlight the information in the Merchant Key field. Go to the Edit menu to select the Copy option.

In STX, click inside the Merchant Key field and go to the Edit menu to select the Paste option. 

This will place the Merchant Key information into the Merchant Key field, but it will be a string of bullet points instead of the string of numbers and letters shown in the email. This is for security purposes.

Once you have entered the company’s merchant information, click Save and close the window.

Setting Up STX (Employee Merchant Account)

Go to Setup: Employees and highlight an employee with an individual merchant account, and go to the Payroll tab.

Enter the appropriate information for the employee’s merchant account.

To have a Tip Line for the employee included on their individual electronic payments receipts, check the Receipts Include checkbox.

Set the Processor popup menu to Tempus.  

Leave this screen open and refer to the employee’s email from your First Data EMPS  containing the Merchant ID and Merchant Key.

NOTE: The following TEST information is used to show how the formatting of the information will be similar to the employee merchant information, and in no way reflects any of the individual employee merchant information.

Highlight the Merchant ID from within the employee’s email and go to the Edit menu to select the Copy option. 

In STX, click inside the Merchant ID field and go to the Edit menu to select Paste.

This will place the Merchant ID information into the employee’s Merchant ID field in STX. 

Highlight the information in the Merchant Key from within the employee’s email and go to the Edit menu to select the Copy option. 

In STX, click inside the Merchant Key field and go to the Edit menu to select the Paste option. This will place the Merchant Key information into the Merchant Key field in STX, but it will be a string of bullet points instead of the string of numbers and letters shown in the email. This is for security purposes.

If you have other employees with individual merchant accounts, follow the same steps for each employee. Once you have finished each employee, click Save and close the window. 

IMPORTANT: Each individual employee merchant account will have a unique ID and Key. There are no 2 merchant accounts with the same ID and Key information.

Receipt Printer and Printing Receipts

In order to use a receipt printer with credit card processing, you must first have a receipt printer installed and set up on the computer. Once the receipt printer is set up on the computer, go to STX: Preferences: Receipts. A preferences screen will appear.

Select the receipt printer from the Receipt Printer popup menu. Check the box Default Client Visit to Print Receipt if you would like a 3rd and final receipt to print each time a ticket transaction is closed. This final receipt details all purchases/refunds from the ticket transaction.  

You may uncheck Default Client Visit to Print Receipts to disable automatic printing of the final receipt, unless you specifically check the "Print Receipt" box before closing a ticket transaction. Close the STX Preferences window when the desired options are set.

The credit card industry has created new rules that require all merchants processing credit cards to be certified annually. Part of that process involved STX becoming certified as a condition of your business being certified. One of the new conditions for certification is the requirement that duplicate receipts be printed. You have probably seen these duplicate receipts in the past if you have used a credit card at a restaurant. The first 2 receipts printed during the ticket transaction will only print when a credit card is selected as the payment type. PCI compliance rules require that both receipts be printed and this cannot be disabled.

If you wish to print a Tip Receipt prior to actually processing the credit card payment, click the Print Tip Receipt icon in the toolbar of the ticket transaction. 

Turning on Electronic Payments

Go to Setup: Finance: Payment Types. 

Highlight each Credit Card payment type and check the box labeled Process Payments Electronically

This will automatically check the Uses Reference Field box. Leave them both checked.
