a) I do not sign an annual contract with my clients, so such document does not exist. I believe I provided you with the initial contract I signed with SXP, and its renewal is automatic and implicit.
b) I highly doubt that SXP is willing to sign a form indicating they owe money to Blue Energy because they already paid that invoice. I would like to make an attachment indicating they did so.
c) I would greatly appreciate if you could cc our Office Manager K. Yupawadee on all these requests, she is very good at making sure they are addressed, and I am not.
d) I changed the wording slightly on the document I'm sending you, just providing additional specificity as to who owes what to whom. I hope it's ok.
