Imaging you can get a signature from a client who pays your invoices: you ask for a full name and to write a signature before clicking Pay
button. This Add-on makes your imagination come true.
Payers sign invoices directly in a browser by drawing a signature with their mouses or finger (if on mobile or tablet). After payment signature appears on invoice receipt page and on edit invoice page as well in a specific metabox.
P.S Not for manual payments option.
