An invoice form template is quite similar to a basic invoice template and the only distinguishable factor is that it is created using only tables. An invoice form template can be created using either MS Word or MS Excel. It is always recommended to use the latter versions of Microsoft Office like XP, 2007 etc., as these versions offer more flexibility and tools for creating an invoice template. The advantage of using Excel over Word for creating an invoice form template is that it is easier to create tables and the Auto Sum feature can also be used.
Both Microsoft Office Word and Excel have their own distinct advantages. If you need to create a simple invoice template form with minimum information and characters then creating in MS Word would save you time. If you need several tables and sub-tables and if there is a lot of data that needs to be incorporated then MS Excel would be most appropriate
