"It also failed to provide over 100 customers with a copy of their layby sales agreement terms and conditions when they entered the contract, as required under the FTA."
Sentencing judge Ema Aitken said the company targeted the most vulnerable members of society, who she described as "the precariat" -- those living in precariously balanced circumstances, for whom a single event could tip an individual or family into poverty or at the very least create significant difficulty.
The company submitted that it was not aware of legal requirements and that it had simply used the same contracts as other providers.
But Judge Aitken said this was not a mitigating factor and described the offending as verging on gross negligence.
"I reject strenuously the notion that Bestdeals is less culpable because it failed to take legal advice," she said.
Commissioner Anna Rawlings said over 1000 debtors were affected by Bestdeals' offending.
"Some of the Bestdeals credit contracts failed to include basic information such as the total number of payments required and the amount of those payments," she said.
Rawlings added that businesses choosing to operate in the consumer credit market must be familiar with and follow consumer credit laws.
"Businesses should also make sure that they are complying with the FTA including laws applying to particular sales methods that they choose to use, such as layby sales."
