Purchase HSUs

Last updated on

Buy Harness Subscription Units (HSUs) with a credit card to add capacity to your account. Checkout takes a few steps and your new balance is available within seconds of a successful payment.

Before you begin​

  • A valid credit card: Harness processes the payment through a payment provider. No specific role or permission is required to complete checkout.
  • A capacity estimate: The minimum purchase is 5,000 HSUs per year. Go to HSU Calculator to estimate your annual consumption.

The purchase option is available on any account, whether on the Free plan or on Essentials. You do not have to reach a usage threshold to buy.

Purchasing ends your Free plan immediately

Completing this purchase moves your account to Essentials, forfeits your remaining Free HSUs rather than adding them to your purchase, and pins your rate card for the contract term. Go to Plan changes and rate cards to review the full list of effects before you continue.

Start checkout​

  1. Navigate to Account Settings.
  2. Select Subscriptions.
  3. Click Purchase HSUs.

Select the number of HSUs​

  1. Enter the number of HSUs you want to buy. The minimum is 5,000 HSUs per year.
  2. Review the total cost that Harness calculates for the quantity.

HSUs are charged at your plan's per-unit rate. Go to Harness Flex Pricing to review tier rates.

Enter payment details​

  1. Enter your card number, expiry date, and security code.
  2. Enter the billing details requested for the card.

Harness passes these details to the payment provider. Harness does not store your card number.

Review and confirm the purchase​

  1. Confirm the HSU quantity and the total cost.
  2. Click Purchase.

Harness submits the payment and shows the transaction status while the payment provider verifies it. Keep the page open until the status resolves. Go to Transaction status to interpret each state.

caution

If the transaction fails, Harness blocks further payment attempts on the account for 30 minutes. Confirm your card details and quantity before you click Purchase so you do not have to wait out the block.

Confirm your new balance​

When the transaction succeeds, Harness shows a checkout complete page. Review it before you leave, because it confirms the number of HSUs purchased, the amount charged, your new plan and HSU balance, and your contract renewal date.

To verify the purchase against your account:

  1. Navigate to Account Settings.
  2. Select Subscriptions.
  3. Confirm that your HSU balance includes the purchased units and that the plan shows Essentials.

The payment provider sends a payment confirmation that records the charge. Harness also records the purchase on your transaction history page. Go to Invoices and refunds for the steps.

If the payment confirmation does not arrive, check the Subscriptions page for your updated balance, then contact Harness Support if the balance is unchanged.

Buy more HSUs later​

A Free account can complete one self-serve purchase. To add capacity within an existing term, contact the Harness sales team.

Additional HSUs bought within a term are charged at the same rate card as your first purchase and are coterminous with your original contract, so they end on your existing contract end date. Go to Plan changes and rate cards to understand how pricing and dates are applied.

Troubleshooting​

My card was declined during Harness HSU checkout

Confirm the card number, expiry date, security code, and billing details, then check with your card issuer that online and international charges are permitted. If the transaction failed, wait 30 minutes before you attempt payment again.

Harness will not let me attempt payment again after a failed HSU purchase

A failed transaction blocks further payment attempts on the account for 30 minutes. Wait for the block to clear, then start checkout again with corrected card details.

I purchased HSUs in Harness but the Subscriptions page still shows my old balance

Refresh the Subscriptions page, because the balance updates within seconds of a successful payment. If you received a payment confirmation but the balance is unchanged after a few minutes, contact Harness Support with the payment confirmation.

Harness rejected my HSU quantity as too low during checkout

The minimum self-serve purchase is 5,000 HSUs per year. Increase the quantity to at least the minimum, then continue with checkout.

Next steps​

Your capacity is available immediately.
