Terminología y conceptos clave en facturación comercial

Understanding how to read an invoice and communicate payment details in English is a fundamental skill for any business professional. This lesson breaks down the essential vocabulary found on a standard invoice, from seller and buyer details to payment terms and modern payment methods, giving you the confidence to handle transactions fluently.

What information appears on a standard invoice?

Every invoice contains key sections that both the seller and the buyer need to review carefully. The seller information and buyer information [0:30] typically include the person's name, the company, address, and phone number. These details establish who is involved in the transaction.

Beyond the contact details, every invoice includes:

• Invoice number: a unique identifier for tracking purposes.
• Invoice date: when the invoice was issued.
• Terms of payment: the conditions that tell the buyer when and how much to pay [1:02].
• Due date: the last day the buyer can make the payment.

The terms of payment section deserves special attention because it dictates the financial relationship between buyer and seller.

What does net 30 mean in payment terms?

The term net 30 [1:22] simply means the customer has 30 days to pay the invoice in full. It is one of the most common payment terms in business-to-business transactions.

A variation like 2/15 net 30 [1:35] adds a special incentive. The "2/15" portion means the buyer can receive a 2% discount if they pay the remaining balance within 15 days. If they choose not to take advantage of the discount, the standard net 30 terms still apply.

Another important term is installment [1:58], which refers to a partial payment made on a regular basis, such as monthly. It functions as a financing option that allows customers to spread the cost over time.

What do COD, CIA, and S&H stand for?

Business English is full of acronyms that appear on invoices and shipping documents. Knowing them saves time and prevents confusion.

• COD (cash on delivery) [2:16]: the buyer must present cash and pay at the moment the order is delivered.
• CIA (cash in advance) [2:30]: the customer pays for the order before it leaves the warehouse.
• S&H (shipping and handling) [2:42]: covers all costs associated with getting a customer's order from point A to point B.

A related term is freight [2:52], which also involves moving products between locations but is typically reserved for large, heavy items transported by trucks, planes, boats, or trains.

How are modern payment options discussed in English?

When a sales rep is ready to accept payment, they often ask a simple question: "Cash or card?" [3:14]. This is the standard way to ask which form of payment the customer prefers.

A bank card or debit card and a credit card are sometimes informally called plastic [3:30]. A customer might ask, "Do you accept plastic?" or "Do you take plastic?" — they are simply asking whether they can use a card.

Finally, contactless payment [3:45] refers to passing a card or phone over the payment terminal or lightly touching it, rather than inserting the card or handing it to the sales rep. This method has become increasingly popular in everyday transactions.
