Should you offer an early-payment discount? Here's how to tell

A client asks you: "give me a 5% discount and I'll pay you today instead of in 30 days." It sounds tempting when you need cash in the bank. But giving away margin without measuring it can cost you more than you think. Here's a quick way to decide, without guessing.

The problem: fast cash vs. lost margin

When cash flow is tight, any immediate payment looks like a lifesaver. The risk is that the discount becomes a habit: the client always expects it, and you end up giving away a fixed percentage of your sales month after month, without ever consciously deciding it was worth it.

The point isn't "never offer a discount." It's knowing the real cost of the time you're saving, so you can compare apples to apples.

A simple formula to decide

A practical approach (illustrative, not a fixed rule) is to turn the discount into an annualized rate and compare it to what it actually costs you to get that same cash another way (for example, a short-term loan or your working capital line).

Reference formula:

Annualized rate = (Discount % / (100 - Discount %)) × (365 / days you move the payment up)

Illustrative example: you offer a 5% discount for paying today instead of in 30 days.

• Discount: 5%
• Days moved up: 30

(5 / 95) × (365 / 30) ≈ 0.0526 × 12.17 ≈ 64% a year

In other words, that "small" 5% is equivalent to borrowing money at 64% a year. If your real financing cost is much lower than that, you're probably better off looking for a short-term loan or a working capital line, instead of giving away margin every month.

Note: these are illustrative numbers meant to show the method. Your own case may vary by client, industry, and business conditions — always run the numbers with your own figures.

When it does make sense (and when it doesn't)

An early-payment discount can make sense when:

• You have a one-off cash gap (not a structural one) and need to close a specific hole this month.
• The client has a high risk of late payment or default, and getting paid fast reduces that risk by more than the raw number suggests.
• The margin on that product or service is wide, and a small percentage won't put you in the red.

It probably doesn't make sense when:

• You already have access to credit cheaper than the discount's annualized rate.
• The client pays on time anyway, and the discount just eats your margin without changing anything in practice.
• Your margin per product is already thin, and every percentage point counts.

A cheaper alternative is usually improving your collections process: automatic reminders, clear invoicing from day one, and timely follow-up. Often a late payment isn't because the client doesn't want to pay — it's because no one reminded them on time.

The habit that's actually worth building

More than deciding once whether to offer the discount, what really helps is always having visibility into how much money you have tied up in receivables and how much it will cost you (in time or in discounts) to bring it in sooner. That visibility is what lets you negotiate with a clear head, instead of on instinct when cash is tight.
