Bizprac streamlines the management and claiming process for both creditor and debtor retentions, ensuring contract fulfillment and compliance.

Introduction to Retentions

Bizprac facilitates the claiming of creditor retentions through a structured process, allowing for full or partial authorisation of retentions. Once authorised, retentions can be claimed, generating invoices marked with 'RI' for easy identification and payment processing, ensuring accurate financial transactions and compliance​​. Retentions is a percentage of a payment that is held either by a client or the main contractor as security to ensure that the works will be completed and any defects that arise will be rectified. Retentions are calculated as a percentage of the contract value. In some cases a Bank Guarantee may be provided instead of Retentions. Alternately a combination of retentions and bank guarantee can be used.

Debtor Retentions

A debtor retention is an amount that is retained or deducted from an invoice submitted to a debtor. The Debtor can only do this if we have a signed contract for a job/project agreeing to the retention terms. This money is held to ensure the completion of the contract and will be released in accord with the terms of the contract.

Claiming a Debtor Retention

All outstanding retentions will be listed in the Debtor Retentions. Sorts can be applied by Debtor or by job. Reminders and due dates can be set.

Creditor Retentions

A creditor retention is an amount that is retained or deducted from an invoice submitted by a creditor. The retention is deducted from submitted invoices as security for the completion of works and or defects to a satisfactory standard. In QLD, Retention Trust accounts must be used for the management of retention funds. Please refer to the Trust Account guide for details. In Bizprac, Creditor Retentions are setup through the Creditor Contracts window. A contract can be entered manually or created from a purchase order.
