Hi Dee. It looks pretty good. I would think adding Nunc pro tunc (now from then) would be a good idea, thereby being able to go back to day one, your first letter, and bill them for everything from that time forward, even at your fee schedule rate it could return a pretty nice sum of money back to you if it came to court and they lost. It might also make them think a bit harder about what tack they are using on you, The bigger the bill, the more they are unlikely to want to challenge it at a later date. Just my thoughts on it. I guess you could also say that due to the rise in the cost of living you have now decided to increase your fee schedule. They do it, so can you. You could also introduce late fees, for interest incurred whilst waiting for payment. Some companies charge extortionate amounts in interest. Remember this is commerce you are acting in business mode.
