If the purveyor requires that a backflow tester pay for test submissions you must add a credit card to your profile in AquaResource.

A Credit Card(s) can be used in two ways.

First, your card can be charged each time a passing backflow test report is submitted.

Second, and optional, a balance equal to 1 to 50 passing test report submissions can be added to a credit card in AquaResource in a single transaction. Placing balance in the system is designed to cut down on credit card transaction fees imposed by the card issuer and/or allow more transactions in a single day without shutting down the card by fraud detection.

Adding a Credit Card

  • Go to https://backflow.tecnxs.com
  • Stay on the Login tab then use the email address and password you registered with to login to AquaResource
  • In the upper right-hand corner of the screen click on the circle with your initials, then click on profile
  • Click on Payment
  • Click on the + button in the top right corner of the Credit Cards table.
  • Enter your the credit card information
    • Receipt email address is where receipts are sent when using this credit card
    • Assign to company, optional, select a company to assign the credit card to or leave empty if you want it assigned to your account. If a company is selected this card is assigned to that company. You MUST first setup a company under the Companies tab to be able to assign it to a credit card.
      • Credit card(s) will be debited when a test report is successfully submitted or if using the balance system the balance can not cover the cost to pay for the test


Your credit card is charged each time a passing backflow test report is submitted you will receive a receipt for each backflow test. Stripe charges a credit card for each test/transaction and sends a receipt.

Add a Balance to a Credit Card

  • To add funds to your account, under the Payment tab, click on the Add Money button. Select the amount to add to your account and then choose the credit card. Then click on Add Money. Your card will be charged for that amount.
  • To add funds to a company, under the Companies tab, within the Companies table, click on Add Money on the row with the company you want to add money to. Select the amount to add to the company and then choose the credit card. Then click on Add Money. Your card will be charged for that amount.

When using the balance system in AquaResource each tester will need to have a balance added to the credit card under their profile. Even if there is only one credit card being used by multiple testers this holds true. Credit card receipts that come from TecNXS/AquaResource are generated and emailed by Stripe which is a third-party vendor used to handle all credit card transactions. The receipts that you receive have been stylized by our company with a logo and other items.


If you choose to use the balance system in AquaResource you will only receive one credit card receipt from Stripe for the amount added to the balance system. If you add a balance to more than one tester you will a receive a receipt for each.

You will not receive a credit card receipt for each passing backflow test/transaction if you use the balance system. This is because the transaction cleared through Stripe, previously, as a single transaction, when the balance was added. The balance will be drawn on by AquaResource each time a passing test report is submitted. AquaResource itself does not generate a credit card receipt.

TecNXS doesn’t

TecNXS doesn’t retain or have access to your credit card information. We use Stripe as a, PCI compliant, payment platform.
