Sending invoices by email is the simplest and fastest way to get paid. Whether you’re a freelancer, small business owner, or independent contractor, a well-written invoice email makes your billing process smoother and more professional.
Here, we’ll guide you through how to send an invoice through email step by step, what to include, common mistakes to avoid, and best practices to ensure you get paid on time.
Sending invoices by email is faster and more reliable than traditional methods. It cuts out printing, postage, and waiting days for delivery. Everything is digital, which means both you and your client have a clear record of what was sent and when.
Most clients now expect to receive invoices directly in their inbox, and a professional invoice email makes it easy for them to review, process, and pay without delay. The result: smoother transactions, fewer missed payments, and less admin for everyone involved.
Before you draft your invoice email, double-check that the invoice itself is polished and accurate. Every detail matters — from the client’s name and contact information to the payment terms and due date. A complete, well-structured invoice saves back-and-forth questions, builds trust, and makes it easier for your client to process the payment quickly.
Every invoice should include:

Always send invoices as a PDF. It’s the standard format because it looks professional, is easy to open on any device, and keeps your formatting intact. A PDF also prevents accidental edits, which protects the accuracy of your records.
Word documents and spreadsheets may look fine on your screen, but they can appear differently on the client’s side — or worse, be altered without meaning to. A clean, locked PDF gives both you and your client confidence that the invoice is final and ready for payment.
Tip: Use clear file names like: Invoice_YourBusiness_ClientName_1234.pdf
There are two main ways to create and send invoices by email, and the right choice depends on how often you bill clients and how much time you want to spend managing payments.
Here’s how to send an invoice via email in a way that’s professional, clear, and easy for your client to act on. Each step keeps the process straightforward, reduces the chance of delays, and ensures your invoice stands out in a busy inbox.
A good subject line makes your invoice easy to find and prevents it from getting lost. For example:
Make sure it goes to the right person. If your client has an Accounts Payable department, use their email. Otherwise, send it directly to your contact. Always use a polite greeting like “Dear Alex” or “Hello Jamie.”
Start with a direct line so the client knows exactly why you’re emailing. For example:
“Please find attached Invoice #1234 for consulting services provided in August.”
Repeat the most important details for quick reference:
You can also add one short line about the project or service. For example:
“This invoice covers the social media campaign delivered in August.”
Attach your invoice as a PDF. Double-check the file is attached before sending. Use a consistent naming format so clients can quickly identify it.
Make it simple for the client to pay you. If possible, include:
Close politely and include your contact details in case they have questions:
“Thank you for your business. Please let me know if you need anything further.”
Then sign off with your full name, company, phone, and email.
Before you click send, check:
Good invoicing habits make it easier to manage your cash flow and build strong client relationships. A professional invoice email isn’t just about sending the document — it’s about making the whole process simple for both sides.
