Grouping the Invoices

Hi,
We work on a service industries, where for each project we have lots of invoices. also form the same customer (and supplier) we will l have multiple projects. when we create invoice and track them it is bit difficult to search especially of there any error (eg, forgot to activate VAT button) etc. is there a way we can group the invoice based on customer. and driven down to project then to invoice? it will be something like below.

?Tracking codes
See
Tracking Codes: Use tracking codes | Correct missing tracking codes

You can also search the Sales Invoices tab for the customer’s name. See Search for records | Manager. And you could add a custom field for the project name, set to show as a column, then search for the project name.
