Who should sign an invoice?

An invoice is a critical component for many businesses. Learn about who should sign your invoices and how to quickly and easily collect digital signatures.

Businesses let clients know how much they owe by sending invoices. Although client signatures aren’t always legally required, doing so can make it easier to fast track payments and more.

Invoices before and after payment.

Businesses invoice clients regardless of whether the amount owed has been paid because it serves as a contract and/or receipt. If your client has already paid, your invoice should clearly indicate that nothing is due and it should also include your signature.

If the client hasn't yet paid, your invoice should include your signature and a space for their signature. Once the client signs the invoice, they've legally agreed to pay the amount owed.

Make your invoice legally binding with the right signatures.

Invoices outline the details of what someone owes you, usually goods and services. However, an invoice is generally considered a one-sided agreement until the client has signed it.

Once you’ve collected a legally-binding signature, your invoice can technically be considered a contract. If you set up your invoice correctly, a client signature represents their agreement to submit payment in full. Depending on the e-signature software you use, you can track your invoice’s progress directly from the application’s dashboard.
