How to Get Paid Faster: Invoice Payment Terms, Late Fees & VAT Rules for 2026
Late payments cost European businesses an estimated €1 trillion each year in lost cash flow, financing charges, and administrative time. This guide shows you exactly how to set payment terms that get you paid on time, charge interest when clients pay late, validate bank details before you invoice, and stay compliant with EU VAT invoicing rules — including the upcoming ViDA e-invoicing changes.
- Write a real due date, not just "Net 30". If you state no payment term at all, the Late Payment Directive default applies — 30 days from receipt of the goods or services, or from the invoice date, whichever is later. Silence does not buy you extra time.
- 60 days is the EU ceiling for B2B payment terms, with limited exceptions. A 90-day informal term is a negotiation signal, not a legal norm.
- Statutory interest needs no contract clause. It applies automatically at the ECB main refinancing rate plus 8 percentage points (UK: Bank of England base rate plus 8%), plus fixed compensation of at least €40 or £40.
- Validate the payer’s IBAN before you send the invoice. A misdirected payment is a 30–60 day problem, not a five-day one.
- Check the field list every time. Which fields are mandatory depends on the transaction and on national rules, and the consequence of an omission varies by jurisdiction. An invoice missing a required detail may lose its VAT deductibility, so treat the list as a checklist rather than assuming a missing field is merely cosmetic.

Setting Invoice Payment Terms That Actually Work
What Are Payment Terms?
Payment terms tell your customer exactly when the invoice is due. They appear on every invoice you send and form a legally binding agreement once the client accepts the invoice. Common terms include Net 7, Net 14, Net 30, 2/10 Net 30, and Due on Receipt.
If you do not specify payment terms on your invoice, the EU Late Payment Directive applies a default: payment is due 30 days after receipt of goods or services (or 30 days after the invoice date, whichever is later). This means "no due date" is not an excuse for the debtor — and it is also not good for your cash flow.
The Most Common Payment Terms Explained
| Term | Meaning | Best For |
|---|---|---|
| Due on Receipt | Payment due immediately when invoice arrives | Freelancers, one-off projects |
| Net 7 | Due within 7 days of invoice date | Repeat clients, subscriptions |
| Net 14 | Due within 14 days | SMBs, service providers |
| Net 30 | Due within 30 days (EU statutory default) | Most B2B transactions |
| Net 60 | Due within 60 days | Large corporations, government |
| 2/10 Net 30 | 2% discount if paid in 10 days, otherwise due in 30 | Encouraging early payment |

Which Payment Term Should You Choose?
The right payment term depends on three factors:
- Your cash flow needs: If you have monthly expenses like rent or salaries, shorter terms (Net 7 or 14) keep money coming in before bills are due.
- Your industry norms: Construction and manufacturing often use Net 60. Consulting and creative services typically use Net 14 or Net 30. Check what competitors offer.
- Your client size: Large enterprises often impose Net 60 or even Net 90 on smaller suppliers. Push back if possible — the EU Late Payment Directive caps payment terms at 60 days for B2B transactions (with limited exceptions).
The Early Payment Discount Strategy
The 2/10 Net 30 term is one of the most effective tools for improving cash flow. Here is how it works:
- Invoice amount: €5,000
- Standard due date: 30 days
- Early payment discount: 2% if paid within 10 days
- Discount amount: €5,000 × 2% = €100
- Early payment total: €4,900
From your perspective, getting €4,900 ten days early is often better than waiting 30 days for €5,000 — especially if you can invest that money into growth. From the customer perspective, saving €100 for paying 20 days early is attractive. The implied annual interest rate of a 2/10 Net 30 discount is approximately 36.7%, which is why it works so well.
How to Write Payment Terms on Your Invoice
Always include a clear, specific due date. Instead of writing "Net 30," write:
Payment due: 14 October 2026 (Net 30 from invoice date 14 September 2026)
Also include:
- Accepted payment methods: Bank transfer, SEPA Direct Debit, card
- Bank details: IBAN, BIC/SWIFT, account holder name — validated with an IBAN checker before sending
- Late payment notice: "Statutory interest will be charged on overdue amounts" — this reinforces your legal right (though the right exists regardless)
- Purchase order reference: Many enterprise clients require a PO number to process payment
Validate Bank Details Before You Send the Invoice
One of the most common reasons for payment delays is incorrect bank details. An invalid or transposed IBAN causes the bank to reject the transfer, the payment bounces back, and your client has to start the process again — adding days or weeks to the payment cycle.
Why IBAN Validation Matters
Every EU bank transfer requires an IBAN (International Bank Account Number). Before you put bank details on an invoice, validate them:
- Format check: The IBAN must match the country's expected length (Germany: 22 characters, France: 27, Netherlands: 18, etc.)
- MOD-97 check: The mathematical algorithm confirms the check digits are correct — catching typos and transposed digits
- Country code: The first two letters must match a valid ISO country code
Use the free IBAN Validator to check any IBAN in seconds. It supports 30+ countries and performs MOD-97 validation entirely in your browser — your bank details never leave your device.
Other Details to Validate
- VAT number: If you are charging VAT to a business client, verify their VAT number through VIES (VAT Information Exchange System) before issuing the invoice. An invalid VAT number can invalidate your reverse charge claim.
- Company name and address: These must exactly match the client's legal registration. Mismatches cause invoice rejections under some corporate AP systems.
- PO number: Without a valid purchase order reference, many large clients will not process the invoice at all.
The VAT Number Validator checks VAT numbers against the official VIES database in real-time. Run it before every cross-border invoice to avoid costly corrections.
What Every VAT Invoice Must Include in 2026
An invoice that does not meet VAT requirements can be challenged by a tax authority, causing you to lose the right to charge or recover VAT. Here is the complete checklist of required information under EU VAT Directive Article 226:
Mandatory VAT Invoice Fields
| # | Field | Notes |
|---|---|---|
| 1 | Sequential invoice number | Must be unique and gap-free |
| 2 | Date of issue | When the invoice was created |
| 3 | Supplier name and address | Legal registered address |
| 4 | Supplier VAT number | Your VAT ID |
| 5 | Customer name and address | Buyer registered address |
| 6 | Customer VAT number | Required for B2B cross-border |
| 7 | Description of goods/services | Clear, specific description |
| 8 | Date of supply | If different from issue date |
| 9 | Net amount (excl. VAT) | Per VAT rate |
| 10 | VAT rate applied | e.g., 20%, 19%, 7% |
| 11 | VAT amount | Calculated per rate |
| 12 | Total amount payable | Including VAT |
| 13 | Payment terms | Due date and late interest notice |
VAT Calculation Quick Reference
To calculate VAT on an invoice, use these formulas:
VAT Amount = Net Amount × VAT Rate
Gross Amount = Net Amount + VAT Amount
Net Amount = Gross Amount ÷ (1 + VAT Rate)
Example: A €1,000 net service in Germany (19% VAT):
Use the free VAT Calculator to compute VAT for 30+ countries with correct standard, reduced, and super-reduced rates built in.
To build an invoice carrying those fields, use the free Invoice Generator — it includes VAT calculation, sequential numbering, IBAN fields, and PDF export. Treat it as a template, not a compliance check: Article 226 sets out 15 numbered particulars, and only some apply to any given transaction. The exact set depends on the supply type and on national rules, so confirm the required fields for your situation rather than assuming the output satisfies them.
Reverse Charge: When the Customer Pays the VAT
In cross-border B2B transactions within the EU, VAT is usually not charged by the supplier. Instead, the reverse charge mechanism shifts responsibility to the customer. On your invoice, write:
Reverse charge: VAT to be accounted for by the recipient (Article 196, VAT Directive)
For the reverse charge to apply, the customer generally needs to be taxable and established or registered in the destination Member State, and the invoice must carry the customer's VAT number - Article 226(4) requires it. A VIES check confirms a number is reported as valid at that moment; it does not by itself establish that the supply qualifies. Use the VAT Validator for the lookup, and confirm the rest against your national rules.
What to Do When the Client Pays Late
Despite your best payment terms, some clients will pay late. Here is exactly what to do, step by step.
Step-by-Step Late Payment Recovery Process
- Day 1-3 after due date — Friendly reminder: Send a polite email: "Just checking that our invoice #[number] due on [date] has been processed." Most late payments are administrative errors, not refusals.
- Day 7-10 — Second reminder with interest notice: Escalate politely. Mention that statutory interest begins accruing. This often triggers payment.
- Day 14-21 — Formal demand: Send a formal letter stating the outstanding amount, accrued interest, compensation fee, and a 7-day deadline. Cite the EU Late Payment Directive (2011/7/EU) or UK Late Payment of Commercial Debts Act 1998.
- Day 30+ — Escalation: Options include a debt collection agency, small claims court (for amounts under €5,000 in most EU states), or suspending further work/services.
How to Calculate Late Payment Interest
Statutory interest applies automatically — you do not need a contractual clause.
EU formula: ECB Main Refinancing Rate + 8 percentage points
UK formula: Bank of England Base Rate + 8 percentage points
Interest is calculated daily from the day after the due date:
Interest = Invoice Amount × Statutory Rate × Days Overdue ÷ 365
Worked Example: €8,000 Invoice, 30 Days Overdue
Use the free Late Payment Interest Calculator to compute the exact amount owed on any overdue invoice — both EU and UK rules are supported.
For a detailed breakdown of UK-specific rules including the Bank of England base rate and tiered recovery fees (£40/£70/£100), read our UK Late Payment Interest guide.
The €40 Compensation Fee
Beyond interest, the EU Late Payment Directive (Article 6) gives you an automatic right to a minimum €40 compensation for recovery costs. This covers:
- Administrative time spent chasing the payment
- Accounting and bookkeeping overhead
- Communication costs (reminders, letters)
If your actual recovery costs exceed €40, you can claim the full reasonable amount under Article 6(2). This is in addition to the interest.
ViDA E-Invoicing — What Changes in 2026
The EU VAT in the Digital Age (ViDA) directive is the biggest change to European invoicing in decades. It introduces mandatory digital reporting and structured e-invoicing for cross-border B2B transactions.
Key ViDA Changes
- Mandatory e-invoicing: All cross-border B2B invoices must be issued in a structured format (such as UBL, Factur-X, or Peppol BIS) — PDF and paper invoices will no longer be accepted for these transactions.
- Digital reporting requirements (DRR): Cross-border B2B transaction reporting is being introduced in stages at EU level; timelines and deadlines differ by phase and country — check the current Commission timeline rather than assuming a single deadline.
- Platform economy rules: Digital platforms facilitating short-term accommodation and passenger transport must collect and report VAT data.
- VAT registration threshold harmonisation: EU-level registration is being simplified in stages (including the Single VAT Registration project), but national thresholds and procedures continue to apply — there is no single EU-wide registration threshold replacing them.
Implementation Timeline
| Year | Milestone |
|---|---|
| 2026 | Member states begin transposing ViDA into national law |
| 2028–2035 | Phased EU rollout: national e-invoicing mandates continue; EU-level Single VAT Registration and cross-border digital reporting arrive in stages — check the current Commission timeline before planning |
| 2030 | Full DRR implementation across all member states |
While the mandatory dates are still years away, early preparation is smart. The UBL E-Invoice Kit lets you generate structured UBL XML invoices today — the same format required under ViDA. Generating compliant e-invoices now means you will be ready when the deadline arrives, without a last-minute scramble.

: Get Paid Faster This Week
- Review your payment terms: If you are using Net 60 or longer, switch to Net 30. It is the EU statutory default and improves your cash flow.
- Add an early payment discount: Offer 2/10 Net 30 to your regular clients. The 2% cost is usually less than the financing cost of waiting 20 extra days.
- Validate all bank details: Run every new client's IBAN through the IBAN Validator before putting it on an invoice.
- Verify VAT numbers: For every cross-border B2B invoice, check the customer VAT number with the VAT Validator.
- Include payment terms on every invoice: Write the exact due date, not just "Net 30." Add a late interest notice.
- Use compliant invoice templates: The Invoice Generator covers the fields Article 226 lists for a standard supply, with sequential numbering and PDF export. Treat it as a template: Article 226 sets out 15 numbered particulars, and which ones apply depends on the transaction and on national rules.
- Set up a late payment process: Diarise invoice due dates. Send automatic reminders at day 1, 7, and 14.
- Calculate what you are owed: Use the Late Payment Calculator to determine the exact interest and compensation on any overdue invoice.
- Prepare for ViDA: Start generating structured e-invoices with the UBL E-Invoice Kit to be ready for mandatory adoption.
- Check VAT rates: Ensure you are charging the correct rate — use the VAT Rates 2026 reference for all 27 EU member states.
What is the best payment term for B2B invoices?
Net 14 or Net 30 are the most common B2B payment terms in the EU. Net 30 is the statutory default under the EU Late Payment Directive when no due date is agreed. Shorter terms like Net 7 or 14 improve cash flow but may discourage some clients.
How do I charge interest on a late payment invoice?
Under EU law, statutory interest applies automatically at the ECB main refinancing rate plus 8 percentage points. In the UK, it is the Bank of England base rate plus 8%. Add a fixed compensation fee of at least €40 or £40. You do not need a contract clause to claim this.
Do I need to validate IBAN before sending an invoice?
Yes. Always validate the customer's IBAN before issuing an invoice with bank details. An invalid IBAN causes payment delays, failed transfers, and additional bank fees. Free IBAN checker tools can verify format and check digits in seconds.
What must appear on a VAT invoice in the EU?
A compliant EU VAT invoice must include: sequential invoice number, date of issue, supplier name and address, VAT identification number, customer VAT number (for B2B cross-border), description of goods or services, net amount, VAT rate, VAT amount, and total payable. The complete checklist has 13 fields — see Part 3 above.
How does ViDA affect invoicing in 2026?
The EU ViDA (VAT in the Digital Age) directive introduces mandatory digital reporting and e-invoicing for cross-border B2B transactions. Member states are transposing the rules between 2026 and 2030. Early adoption means smoother compliance and faster VAT recovery.
What happens if my customer ignores a late payment?
Send a formal payment reminder, then a letter of demand citing statutory interest rights. If still unpaid, use a debt collection agency or small claims procedure. Under EU Late Payment Directive 2011/7/EU, you can recover all reasonable recovery costs in addition to interest and the €40 compensation fee.
