Net 30 and 2/10 net 30: reading invoice payment terms
Invoice terms describe a payment window and, sometimes, a discount for paying early. Confirm the meaning with the supplier before entering a due date or taking a discount in the books.
This guide describes common bookkeeping practice, not a legal or regulatory requirement.

Read the notation against the agreed invoice terms
As common commercial shorthand, a net term names the full-payment window. A slash-separated discount term places the discount percentage before the slash and the early-payment window after it, followed by the full-payment window. Confirm the starting event, eligible invoice amount and receipt requirements with the supplier. This notation is a negotiated business term, not a California default payment rule.
Keep a prompt-payment discount separate from a dispute
CDTFA’s grocery purchase-ratio method defines a cash discount as a reduction from invoice price for prompt payment. In that specific method it treats cash discounts, volume rebates, quantity discounts and promotional allowances as cost reductions. Identify the reason for each adjustment rather than recording a disputed charge as though the supplier offered a discount.

Decide whether earlier payment fits the cash plan
A practical payment review compares available cash, upcoming obligations and the discount actually offered. Confirm whether the supplier must receive payment by the cutoff, and obtain clarification about delivery or processing time. Record the approved choice so the person releasing funds knows why the payment is scheduled.
Separate the due date from revenue recognition
SBA illustrates a January sale paid in February: under accrual accounting the sale is recorded in January, while under the cash method the receipt is recorded in February. The invoice’s payment window does not replace the accounting-method decision. Give your bookkeeper both the sale evidence and the payment terms.

Retain the invoice, discount and settlement evidence
IRS supporting documents for receipts and expenses include invoices, charge slips, canceled checks and account statements. Match the original invoice to any accepted discount and the resulting payment. If a customer does not pay, preserve the history for follow-up rather than rewriting the original agreement to hide the overdue balance.
