I have a customer that I have been servicing since 2000, and just recently for the first time increased their rate 5%. This would be for the first of January, I just received payment late with a note saying they can't afford the increase right now and payed what I have been previously charging them. With all that being said they are good customers that pay almost always on time, and are in a row of about 20 yards I maintain. I would like to keep them but its about time they start paying more for my services. How would you handle this situation? Let them slide for a few months and raise price during summer? Or argue about the fact everything else is going up and you have to charge more. I know my price and its about time for a rate increase.
