Invoicing Best Practices

Send Invoices Promptly

Invoice as soon as work is complete. Delays in invoicing often lead to delays in payment — out of sight, out of mind.

Be Crystal Clear

Vague descriptions cause questions and delays. Instead of "Consulting services," write "Website redesign consultation — 4 hours @ $150/hr."

Set Clear Due Dates

"Due upon receipt" is vague. "Due by February 15, 2026" is specific. Net-15 or Net-30 terms give clients reasonable time while setting expectations.

Follow Up Systematically

Send a friendly reminder a few days before the due date, then follow up promptly if payment is late. Most late payments are due to oversight, not malice.

Keep Records

Maintain copies of all invoices. You'll need them for tax purposes and resolving any disputes. InvoiceForge lets you save drafts locally for this purpose.

International Invoicing Considerations

Working with international clients adds complexity:

Currency

Invoice in your client's currency for their convenience, or your currency if that's your policy. InvoiceForge supports 150+ currencies with proper symbols and formatting.

Tax Implications

VAT rules vary by country. B2B services to other EU countries may be reverse-charged. Consult a tax professional for your specific situation.

Payment Methods

Offer multiple options. Bank transfers (SWIFT) work but have fees. Wise (TransferWise), PayPal, and Payoneer are popular for international payments.

Language

While English invoices are generally acceptable internationally, some countries legally require invoices in the local language. Research your client's requirements.
