PAYMENT TERMS

What payment terms mean

Payment terms explain when and how your customer should pay an invoice.

For a service business, clear payment terms usually answer four questions:

  • How much is due
  • When payment is due
  • How the customer should pay
  • What payment reference they should use

Clear payment terms reduce confusion, make reminders easier and help you separate payment reported from payment confirmed.

COMMON TERMS

Common payment terms: due on receipt, 7 days, 14 days and 30 days

Choose terms that match the job, customer relationship, contract and cash-flow needs.

Payment termMeaningWhen it fits
Due on receiptCustomer should pay when they receive the invoiceSmall call-outs, urgent work, final invoices
7 daysPayment due 7 days after invoice dateSmall service jobs, domestic customers
14 daysPayment due 14 days after invoice dateRepeat customers, mid-size jobs
30 daysPayment due 30 days after invoice dateBusiness customers, agreed trade terms
Upfront depositPart-payment before work startsLarger jobs, materials, booked service slots

Make the due date visible on the invoice instead of relying only on wording such as Net 14. GOV.UK says businesses can set their own payment terms, and if no payment date is agreed, payment is generally due within 30 days after the invoice is received or after goods or services are supplied, if that is later.

Do not rely only on bank details. Add a clear invoice number and payment reference so the customer and business can match the bank transfer to the right invoice.

GOV.UK lists core invoice fields such as a unique identification number, business and customer details, service description, supply date, invoice date, amounts, VAT if applicable and total owed.

BANK TRANSFER REFERENCES

Bank-transfer reference examples

Good payment references are short, unique and easy to copy.

ScenarioExample reference
Standard invoiceINV-1042
Customer name + invoiceSMITH-INV1042
Job number + invoiceJOB-238-INV1042
Deposit invoiceDEP-INV1042
Final invoiceFINAL-INV1042

Avoid vague references such as payment, invoice, thanks or only the customer's first name. They make reconciliation harder when multiple payments arrive on the same day.

OVERDUE LOGIC

When an invoice becomes overdue

Payment is overdue only after the due date has passed and the business has not confirmed receipt of payment.

An invoice becomes overdue when the payment due date has passed and the business has not confirmed receipt of payment.

For bank transfers, do not mark the invoice as paid only because the customer says they have paid. First check the bank account, then confirm the payment in your workflow.

For business-to-business late commercial payments, GOV.UK says agreed payment dates are usually within 30 days for public authorities or 60 days for business transactions, and longer periods for business transactions must be fair to both businesses. If no payment date is agreed, late payment is generally counted 30 days after the customer receives the invoice or after the service or goods are delivered, if that is later.

LATE PAYMENT COSTS

Late payment interest and recovery costs

Use extra caution before adding interest, fees or recovery costs.

For business-to-business invoices, UK late payment rules may allow interest and debt recovery costs in some situations.

This is a legal and commercial area, so check current GOV.UK guidance or speak to a qualified adviser before adding interest, fees or recovery costs to an invoice.

GOV.UK explains that statutory interest for late commercial payments is 8% plus the Bank of England base rate for business-to-business transactions, unless a different contractual interest rate applies. It also says to send a new invoice if interest is added.

GOV.UK also lists fixed debt recovery cost amounts for late commercial payments: £40 for debts up to £999.99, £70 for £1,000 to £9,999.99 and £100 for £10,000 or more.

FAQ

Invoice payment terms FAQs

Common questions about invoice payment terms, due dates, bank-transfer references and payment follow-up.

What payment terms should I put on a UK invoice?

Many service businesses use terms such as due on receipt, 7 days, 14 days or 30 days. The right term depends on the job, customer, contract and cash-flow needs. The due date should be shown clearly on the invoice.

Is 30 days required for every invoice?

No. You can agree your own payment terms. If no payment date is agreed, GOV.UK guidance says payment is generally due within 30 days after the customer receives the invoice or after the goods or service are supplied, if that is later.

Should I use the invoice number as the payment reference?

Usually yes. A clear reference such as INV-1042 helps match a bank transfer to the correct invoice.

Can Joqiva tell me that a bank transfer has arrived?

No. Joqiva can record that a customer reported a payment, but the business should check its own bank account before confirming that the invoice is paid.

Can I add late payment interest?

Possibly, especially for business-to-business late commercial payments, but you should check current GOV.UK guidance or speak to a qualified adviser before adding interest or recovery costs.
