Some independent contractors and hirers use a ‘period contract’, which is a contract template that sets out the terms for a business relationship where the contractor is engaged to perform work from time to time. In the building and construction industry, these contracts are called ‘period trade contracts’.
The contract template will apply each time the hirer offers work to the contractor and the contractor accepts it. This can occur when the contractor provides a quote and receives a work order from the hirer, or the parties might sign an addendum (an addition to the contract) that sets out the specific work to be done or result to be achieved. Once the work starts, the contract template and the work order or addendum will form the total contract for the specific work.
Period contracts can work well for both parties. They allow for the flexibility of performing intermittent work over an agreed period. However, you should check the terms of the agreement to do each new job. Are they the same as those set out in the original contract template? Any term or condition that is different for a particular job may change the terms of the original contract template.
