Trying To Make A Automatic Invoice

im trying to achieve is creating an microsoft word (or simalar) invoice from my excel spread sheet.

My current excel spreadsheet is set on a monthly basis. on it it has my customer list. I provide a service for people so at the end of that month i enter what type of service and who for and make a seperate invoice based on the calculations........ C#&P ive got no idea what im talking about

Im gonna make a fake formula and hopefully somone will understand what im trying to do, everything in these brakets { } is what im trying to do

={cell F6 (customers name)}({send the info in this cell (customers name) to word temlate and insert into customers name section})

Good way to explain it is that i want excell to automaticly create a word invoice, and im guessing i need to have a word template for it.

I really hope someone understands what i am trying to do because at the end of the month it takes about 2 hrs to enter all the different info for the customers into my excel spread sheet and another 2 days to make all the invoices for each customer and it is only a matter of time before i make a simple mistake which could cost me thousands...

was told that words mail merge would work but it wont do what is required. Open to any and all sugestions

I also got told to steer clear of word cos excell can make a good invoice and it would be easier
