Understanding Payment Terms and Cash Discounts

Common Dating Methods

Not all invoices follow the same calendar logic. Depending on the industry and the nature of the goods being shipped, businesses use different "dating" methods to determine when the clock starts ticking for the discount and credit periods.

Ordinary Dating

Ordinary dating is the most common method used in business. Under this system, the payment terms are calculated based directly on the date written on the invoice.

A classic example is the term 2/10, n/30. This is read as "two ten, net thirty." It means:

• If the buyer pays within 10 days (the discount period), they can deduct a 2% discount from the invoice amount.
• Otherwise, the full (net) amount is due within 30 days (the credit period).

End-of-Month (E.O.M.) Dating

In E.O.M. dating, the invoice date is effectively shifted to the last day of the month. This simplifies bookkeeping for companies that receive many invoices throughout a single month. For example, if an invoice is dated July 16 with terms 2/10 E.O.M., the "clock" for the 10-day discount period does not start on July 16; instead, it starts on July 31.

Receipt-of-Goods (R.O.G.) Dating

Some products, especially those imported from overseas, take a long time to travel from the manufacturer to the buyer. In these cases, it would be unfair to require payment based on the date the goods were shipped if they haven't even arrived yet. Receipt-of-goods dating ensures that the discount and credit periods only begin once the buyer actually receives the shipment.

Handling Partial Payments

In real-world business scenarios, a buyer might not pay the entire invoice at once. They might choose to make a partial payment to reduce their total debt.

A critical rule to remember is that if a business makes a partial payment within the allowed discount period, they are entitled to the cash discount on that specific portion of the money paid.

For example, if a company owes $$2,780$ and wants to reduce their debt by $$1,000$ while taking advantage of a $2%$ discount, they don't just send $$1,000$. Instead, they calculate how much cash is needed so that, after the $2%$ discount is applied, the debt is reduced by exactly $$1,000$.

Exam Tip: When calculating the payment required to reduce a debt by a specific amount, remember that the amount of debt reduced is the "net" amount. If the discount rate is $d$, the relationship is: $\text{Payment} = \text{Debt Reduction} \cdot (1 - d)$
