To address your question about calculating the VAT and the Price Including VAT.
You can do this calculation in a Query - as follows:
Create a Query off your Products Table and pull the following fields into the query:
Stockcode
Product type
Products Details
Price
VAT%
You will calculate VAT & Price inc VAT IN your query:
[
You might have to modify the calculation depending on how your VAT% field is defined in your Table - but this is the general idea.]
In a new field in your query, type [or paste] something like this:
VAT_Amount: ([VAT_Percent]/100)*[Price]
In another new field in your query, type [or paste] something like this:
Price_Inc_VAT: (([VAT_Percent]/100)*[Price])+[Price]
Let me know if this gives you the values you need.
The next step would be to use a similar query to build your Invoice.
The invoice query will do something like pull all orders for a particular Customer [how do you identify all the 'current' orders that need to go on the invoice for a customer?].
Then you use this query as the data source for your Invoice report.
Once you've got the first part of your problem resolved [the VAT calculation], we can work on the invoice part if you need help with that.
