I have delt with this situation for a long time...As far as people walking in while in session...I have had to interupt sessions many time to sell GC's. especially durring the holiday season. ย I am fortunate in that my clients encourage me to take care of the sale, as they want to see me prosper, However, I felt it basically ruined the flow of my treatment and that it gave the impression that my future business was more imprtant than my current (ie: client on the table).I have a receptionist now, but I found a FABULOUS solution that I am happy to share with you all...Of course this all depends on your location, so it may not work for you.I really wanted to grab as many GC sales as I could, and being a procrastinator myself, I knew that there had to be others that waited until the last minute to buy gifts. ย So I set up my "After Hours Gift Certificate Sales", and it works wonders!First I bought a white metal mailbox that has a flip lid top and mounts to the wall. ย I put a sign on the out side that says "Gift Certificates" in HUGE letters. ย I screwed it into the exterior of my office wall, to the left of my door. I take 2 GC's, one for male, one for female. ย I put special # series on them, and keep a log for after hour GC's separate from normal sale GC's. ย I put one GC, with it's envelope - BLANK for them to fill out- and another plain env. for them to leave payment. ย In the envelope I put a form for them to fill out...who the GC is for, who bought it, how much, the date it was bought, and a number where they can be reached. ย I put it in a zip-lock baggie, and mark it with BOLD MARKER Female GC (or male, whatever) and put them back in the mailbox. ย On the underside of the lid of the mailbox, I put very explicit directions on what they do to fill out the GC, ย the form that goes with it (to be enclosed with payment) ย Who to make the check out to, the number for them to call the next business day if they would rather pay with credit card, and in BIG, BOLD LETTERS I state that GC'S WILL NOT be honored until they are paid for-no exceptions. ย I also state that I cannot guarantee GC's will be there at all times.I am currently looking for a lock box type of thing for my cash paying clients to feel secure with leaving payment as well.I have been doing this for a little over a year now, and my clients LOVE it! ย It is great for people that are stuck for last minute gifts, or if they can't get to the office before I close, or if I am in session and my door is locked.I am sure I didn't explain this very well, but if you would like me to send you the forms I have made (simple!) or the directions I have for the clients, I will be happy to.Sorry for my ramble! ย But I hope it helps somebody!
