I have a client who has turned into a bit of a bad payer. Apparently a cheque was 'in the post' in September for the last bill. Have chased when cheque didn't arrive but no response.
Had DS2 5 weeks ago so what with one thing and another I let it go temporarily, but now I want to write to him formally. What do you all say/do in similar circumstances? Do you issue a 'reminder' invoice or anything?
