I have (had) a client in which we had done one or two things for (signage and display) and were in the process of developing a logo. Though the two projects were invoiced and paid for, the several (7-10) hours we had spent on logo development have not been. I now have not heard from this client in months, and from word of mouth have heard that they had kind of "strung along" several other businesses in the area, caterers, etc. Is it ok to send them an invoice for say five hours since I can safely assume I am not going to hear back from them or do I just suck it up? Any ideas-experiences would be greatly appreciated!!!
