Why Sign Your Invoices?

A signed invoice carries more legal weight than an unsigned one. If a client disputes payment, a signed invoice proves the authorized signatory reviewed and issued the billing. For freelancers, agencies, and small businesses, signed invoices also signal professionalism — clients treat them more seriously and pay faster.

Under the ESIGN Act and UETA, an electronically signed invoice is legally valid. Your digital signature on the invoice PDF constitutes a legally binding authorization of the billing amount and terms.
