Tarchos Sign is electronic signature software for small offices, built around the paperwork they send over and over. Upload an engagement letter, intake form or agreement once, place the signature and date fields, and save it as a template with named roles like "Client" and "Attorney". From then on, sending it is just the client's name and email. Several templates can be combined into a document packet: the client gets one email and signs everything in one sitting, while each document keeps its own audit trail and completion certificate. On Business and Pro, the client can sign first and the attorney countersign after. Signing emails show the sender or firm's name, and replies go to the office. Pricing is one monthly price for the office rather than per user, with a free plan. Tarchos Sign is made by Tarchos LLC; early customers get direct help from the founder setting up their first templates.
