Last October, I completed a letter of engagement on 13.10.13 for a new client. It stated that he had instructed us to do his accounts and CT600, the first period being 31.03.13, but stated that the client was responsible for completing and submitting their own VAT returns. It was signed and dated before anything was billed or submitted.
Now the client has asked me to do the bookkeeping and VAT work.
Not sure how to proceed regards LOE. What is everyone else doing? Should I just prepare a letter stating the terms for VAT alone- referring to the fact that it's "in addition"? Should I open the old version and add a new paragraph? The reason the latter seems weird is that the amended copy would be dated and signed today.... which would look whacky if it mentioned the 2013 accounts?
Doesnt your original letter of engagement mention something about doing extra work at extra cost, so would cover the VAT element and just invoice separatemforthat. If not then add a new paragraph and get it signed from now. I dont think it actually matters how you do it as long as the client is clear what hes paying for and you cover yourself so that you get paid your true worth.
