How to Return Retention and Generate a Release Certificate

Complete guide to releasing held retention funds and generating release certificates in Mastt

Returning retention releases previously held funds to contractors once contract conditions are met. This guide shows you how to create a retention return payment and generate a release certificate in Mastt.

Before You Start

Return Retention

Create a Retention Return Payment

  1. Go to the Cost module.

  3. Click + Add Payment.
  4. Enter a descriptive name in the Title field (e.g., "Retention Release — Final Payment").
  5. Select the Payment Date.
  6. Set the Payment Status to Paid.
  7. Select the Cash Flow Month.
  8. Click + Add Contract and select the contract that the retention return applies to.

The retention breakdown will only appear on payment letters.

Troubleshooting & FAQs

Q: Can I release only part of the retention?

Yes. Enter a negative amount for the portion you want to release (e.g., -$25,000 when returning part of $50,000 held). You can create additional retention return payments for future releases.

Q: Do I need a separate payment for each contract?

Yes. Each retention return payment must be linked to a specific contract. Create a separate payment for each contract that requires a retention release.

Q: What is the difference between the Retained This Payment field and the Percentage field?

For retention release, always use the Retained This Payment field to enter your negative dollar amount. The Percentage field is not used for retention release.

Q: Why does my retention release show 0%?

If your payment only contains a retention release with no other claimed amounts or line items, the Percentage field will display as 0%. This is expected. The percentage is calculated against the payment total, and with no other amounts in the payment, there is no base to calculate from. The retention dollar amount is still correct and the release will process normally.
