Can i ask you lovely members some advice please. I have a client who sent her accounts to be filed back in January. I have spent at least 3 weeks on sorting it out. Within the last month she has sent me an email apologising for the delays etc as she has been unwell and please be understanding she hasn't had the time to answer my queries. Which is obviously fine I can wait, with have a good relationship. My problem is I have already spent close to a month on the accounts back in Jan and not been paid for the work done. My terms are to invoice on completion of the work and then clients have 30 days to pay. This means that for 3 weeks whilst working on this client i wasn't working on anything else. Do you think i would be rude in invoicing her to pay for half the work done to date? Would love some on advice as to the best way to approach her. Shes been with me for 8 years so not unreasonable at all. Thank you in advance.
