An instalment sale agreement between you and a credit provider allows you to buy a vehicle or asset using the principal debt, which you repay by means of regular instalments over an agreed period, with fees and interest.
The CRA charges instalment interest on all late or insufficient instalment payments. Instalment interest is compounded daily at the prescribed interest rate, which can change every three months.
To write a simple contract, title it clearly, identify all parties and specify terms (services or payments). Include an offer, acceptance, consideration, and intent. Add a signature and date for enforceability. Written contracts reduce disputes and offer better legal security than verbal ones.
A retail installment contract and security agreement is a specific type of contract used in retail sales, where the buyer agrees to make payments over time and provides security for the seller in case of default.
