I use Adobe Sign as a way to send photography contracts to all of my clients. Most of these are wedding contracts, but I do also use it for session contracts and for contract amendments. Each time a client is ready to book with me, I can quickly prepare a form and send it out to them. It has streamlined my processes immensely. It also solves filing issues since I can always find a contract even when I'm not in my office. So, if I'm out during the day (since I work from home) I can pull up the app and look at a contract and keep a great level of professionalism and quick turnaround with clients. It has eliminated printing and scanning and stressing over ensuring I have duplicate copies, etc. when going through the signing process. It allows my clients to see that I have a good handle on my company and they feel better about having a professional in both a creative and business sense for their wedding photography.
