An invoice for the goods is sent, and the seller specifies payment terms on the invoice. This lesson includes:

- Reading of invoice dates;
- Calculating timeline for the end of discount and credit periods
- Ordinary, End-on-the-month, and Receipt of Goods Dating
- Partial Payments

The business selling the goods can offer a cash discount to encourage prompt payment

Ordinary dating, whereby payment terms are based on the invoice date.

`Example`

Determine the payment needed to settle an invoice with a net amount of $750, dated January 26, terms of sale is 2/10, 1/20, and n/60, if the invoice is paid:

i.February 3;

ii.February 14;

iii.When is the end of the credit period?

`Solution`

See the video below.

End-of-month dating, or E.O.M. dating. The invoice date is shifted to the last day of the month.

Determine the payment needed to settle an invoice with a net amount of $750, dated January 26, terms 2/10 E.O.M. paid on February 10.

Receipt-of-goods dating, or R.O.G. is used when the transportation of the goods takes a long time.

A distributor received an invoice of $3240 dated July 10, terms 3/10, *n*/30 R.O.G., for a shipment of goods that arrived on November 14. When is the last day for taking the cash discount and how much is to be paid if the discount is taken?

When a business pays *part* of an invoice within the discount period, the purchaser is entitled to the cash discount on the partial payment paid.

`Example`

A company has received an invoice of $3720 dated June 28, terms 2/10. What payment must be made on July 8 to reduce the debt:

I. by $1000?

A *payment of $980* on July 8 will reduce the debt by $1000.

II. to $1000?

A *payment of $2665.60* on July 8 will reduce the debt to $1000.
