Invoice Payment Terms Explained
What payment terms are
Payment terms tell the customer when payment is due and what happens if it is late. They belong on every invoice and in your contract or quote. Clear terms prevent arguments, make your cash flow predictable and give you a firm basis for following up. Unclear terms are one of the most common reasons invoices are paid late.
Due on receipt
Due on receipt means payment is expected as soon as the invoice is received. It suits small jobs, individuals, new clients and online sales. In practice many customers still take a few days, so some businesses prefer to state a short period such as Net 7 to set a realistic expectation while keeping payment fast.
Net 7, Net 14, Net 15, Net 30, Net 45 and Net 60
Net followed by a number means the full amount is due that many days after the invoice date. Net 7 and Net 14 are common for freelancers and small projects. Net 30 is the standard between businesses. Net 45 and Net 60 are often imposed by large organisations with slow approval processes. The longer the term, the longer you finance your customer, so price it in or negotiate shorter terms.
Choosing terms for different customers
Individuals and new customers should get the shortest terms, or a deposit. Established small businesses usually accept Net 14 or Net 30. Large companies typically work on Net 30 to Net 60 and need a purchase order number. International customers may need extra days for bank transfers, so state the due date as the date money must arrive in your account.
Early payment discounts
A term such as 2/10 Net 30 offers a 2% discount if the invoice is paid within 10 days, with the full amount due in 30 days. It rewards quick payment, but the discount is expensive: 2% for paying 20 days sooner is worth roughly 36% a year. Offer it only if you genuinely need the cash. Use the discount calculator to work out the saving.
Deposits and milestone billing
For larger projects, ask for a deposit up front, often 25 to 50 percent, and split the balance into milestones or a payment plan. This protects you if a client disappears, funds materials and keeps the project moving. Describe each milestone and its amount on the quote so there are no surprises when the invoice arrives. The deposit calculator helps you set the amounts.
Late fees and interest
A late fee must be stated before the work starts, in your contract, quote or invoice terms. A common structure is a percentage per month on the overdue balance, such as 1.5 percent. Many countries cap late fees or provide a statutory rate, so check your local rules. The late fee calculator shows the charge for any amount and number of days.
Writing terms clearly
Good wording is short and specific: “Payment due within 30 days of the invoice date. A late fee of 1.5% per month applies to overdue balances. A 30% deposit is required to start work.” Put the terms on the quote, the contract and every invoice, and repeat the due date explicitly. Avoid vague phrases such as “prompt payment” or “as soon as possible”.
International payments and currency
When you invoice in another currency, state the currency on the invoice and agree who pays bank and conversion fees. Exchange rates move, so consider invoicing in your own currency or fixing the rate on the invoice date. Use the currency converter to check amounts, and remember that the due date should be the day funds must be received.
How the payment method affects timing
Bank transfers are cheap but can take one to three business days, and international transfers longer. Card and online payments are quick but carry processing fees, which you can build into your price. Direct debit gives predictable cash flow once the customer has set it up. Cheques are slow and easily delayed in the post. Whatever you accept, list the methods on the invoice, include every detail the customer needs and say which one you prefer, because a client who has to ask how to pay is a client who pays later.
What to do when the due date passes
Send a friendly reminder the day after the due date, then follow up again after a week with the invoice attached. If there is still no response, phone the accounts contact, apply any agreed late fee and pause further work. Keep records of every message. For unpaid amounts that remain after reasonable effort, consider formal demand letters or professional advice.
