"Some of our younger clients were already making instalments to us on garments so this is just a natural extension."
Customers are required to pay a 20 per cent deposit and then make monthly instalments over a six or twelve month period, but can take their purchases home that day.
Crane said the programme wasn't a result of customers not being able to afford the clothing, but rather a way to better manage the cost, especially for events such as weddings.
"It is a significant purchase for a lot of people," Crane said. "The option of being able to finance a suit is quite beneficial and an exciting proposition because it could mean not having to compromise that part of the wedding - which is something that normally gets squeezed if the budget is a bit tight."
Crane founded Crane Brothers in 1999 and said he had worked hard to carve out a niche in the market since.
He said the arrival of larger international retailers hadn't had much of an impact on the business, but there was always competition for people's time and money.
"Most guys that come to us, by the time they've walked in the door, they've already made a conscious decision that they want to buy," Crane said.
"They know roughly what they want and how much they're going to spend, so if we can put a finance package and pre-approval around that before they come in then it takes all the hassle out of it for them," he said.
"The service is just another tool in our toolbox to allow people to make that commitment.
