I am creating a receipt format on MS Office; which is best applications MS Excel or Ms Word?

My suggestion will be MS Excel. Use MS excel because -

• Changes to the numbers in the receipt will automatically incorporate in final figure if you use formula.
• In excel you will find it easy to design tables or receipt design.
• Excel is meant to play with numbers and receipt contains many of these

I suggest excel very usefull

I suggest it is best to use microsoft excel. its very easy to use it. and you can also preformat the formula in it. hope you find it better :)

My option is MS Excel. because for receipts it is best 

i am totally agree with MS-EXCEL 

Excel without hesitation since it will spare time on you with regards to the data entry, formatting, calculating and other related data formulas. You can maintain the same file as a template for future reference and reuse it for other type of calculations.

Excel would be the way to go.

You have the power of formulas, special formatting options for figures, totals and text.

Labels (Text), numbers and formulas are easily incorporated into the table.

The receipt can be saved as template if required.

Printing options, also allow you to control what and how you want to print.

All the best.
