What it means
The arrangement is simple in outline: the customer takes the goods now, pays a deposit, and repays the balance in agreed instalments with interest or a fee. Legal title often stays with the seller until the final payment, which gives the seller a way to recover the asset if payments stop.
The commercial attraction is extra sales. A customer who cannot fund $24,000 in one go can usually fund $1,000 a month, so offering terms converts prospects who would otherwise walk away, and the interest itself becomes a second income stream.
The cost is cash and risk. Revenue is recognised at the point of sale, but the cash arrives over two or three years, so the seller finances the customer's purchase from its own working capital and absorbs any losses when customers default.
Because in-house lenders often accept customers a bank would refuse, the rates charged are usually higher. This is where the practice attracts scrutiny, since a headline flat rate can look modest while the true annual rate is roughly double, and buyers rarely notice the difference.
The nuance is that in-house financing is only viable if the business can afford to wait for its money and has the systems to collect it. Many companies start with their own book and later sell the receivables to a finance partner, keeping the sales benefit while releasing the cash.
In practice
Real-world examples.
Example
A used car dealer offers finance directly to buyers with thin credit histories. Approval takes twenty minutes rather than three days, and the dealer fits a payment reminder system to keep arrears under control.
Example
A dental equipment manufacturer sells a $60,000 imaging unit to a new practice on a 36-month plan. It retains title until the final payment, which lets it recover and refurbish the unit in the rare cases where a practice closes.
Example
A furniture retailer runs an interest-free twelve-month plan funded from its own balance sheet. It prices the interest cost into the ticket price, so the plan is a marketing tool rather than a lending business.
Formula
Calculation
With a flat, or add-on, interest structure the arithmetic is straightforward.
Amount financed = Cash price - Deposit
Total interest = Amount financed x Flat rate x Term in years
Monthly instalment = (Amount financed + Total interest) / Number of months
A workshop equipment supplier sells a lathe for a cash price of $24,000. The customer pays a $4,000 deposit, so the amount financed is $24,000 - $4,000 = $20,000.
The plan runs for 24 months at a flat rate of 10% a year. Total interest is $20,000 x 0.10 x 2 = $4,000, so the total repayable is $20,000 + $4,000 = $24,000.
The monthly instalment is $24,000 / 24 = $1,000. The customer therefore pays $4,000 up front plus 24 payments of $1,000, which is $4,000 + $24,000 = $28,000 in total for a $24,000 machine.
Note that the flat rate understates the true cost, because the customer does not owe $20,000 for the whole term; the balance falls every month. On a reducing balance basis the effective annual rate here is close to 18%, not 10%.Case study
Seen in the real world.
This case is fictional and illustrative. Draymont Machinery sold small production equipment and lost roughly one in four quotes because customers could not raise bank finance quickly enough. It launched an in-house plan requiring a 20% deposit over terms of up to 30 months, and sales volume rose 31% in the first year.
The problem appeared in the cash flow forecast rather than the income statement. Profit looked excellent, but $1,900,000 of receivables had built up against a $600,000 overdraft, and the company was effectively borrowing to lend. Arrears reached 7% of the book because nobody had been made responsible for collections.
Draymont fixed it in two moves: it hired a credit controller and tightened approval criteria, then sold two thirds of the performing book to a specialist finance partner at a small discount. Sales kept the benefit of easy terms, the balance sheet got its cash back, and the illustrative lesson was that offering credit is a separate business that needs its own people and its own funding.
Watch out
Common mistakes.
- Treating an in-house plan as pure extra profit, while ignoring that the cash is tied up for years and some of it will never arrive.
- Quoting a flat interest rate as though it were comparable to a bank's annual rate, when the flat rate roughly halves the apparent cost.
- Launching a finance offer with no credit assessment, no collections process and no arrears reporting, which turns a sales tool into a bad debt problem.
Questions
People also ask.
How does in-house financing differ from a bank loan?
The seller lends its own money and carries the credit risk itself, rather than introducing the customer to a third party who takes the risk and the interest.
Why do sellers charge higher rates?
Because they often approve customers a bank would decline, and the higher rate has to cover a higher expected level of defaults as well as the cost of the money.
Can a business offer terms without tying up its own cash?
Yes; many sell the resulting receivables to a finance company or use a partner-funded scheme, keeping the sales benefit while receiving cash up front.
