Automate Reminders: Set a calendar reminder for three days before the due date to send a polite follow-up if payment has not yet been received.

FAQ

Should I send the invoice as the body of the email or an attachment?

It is best practice to include a brief summary in the body of the email and attach a formal, professional PDF document that contains all legal and tax-related information.

What information is legally required on an invoice?

While requirements vary by region, most invoices must include a unique invoice number, the date of issue, your contact information, the client's information, a description of services, and the total amount due.

How can I make it easier for clients to pay?

Include a direct link to your payment portal or clear instructions for electronic bank transfers to reduce friction and encourage faster payment.
