Invoice Manager Worksheet

The invoice manager worksheet lets you create new invoices with a click of a button. It lists all the invoices you create and is where you update the amounts paid and the status for each of the invoices. Reports are generated based on the information in the Invoice History table.


Pay Once, No Subscription

Why pay a subscription fee when you don't need or want an online invoicing system?

Free Updates

We aren't going to charge you for future updates. If we create a new version and you want a copy, just return to the download page to get the new files, or email us a copy of your receipt and we'll send you the new workbook.

If Excel changes significantly causing old files to no longer work, you may need to download a new updated version of the file.

Powerful Features

Customize Templates

Easily make copies of the existing templates to pre-populate invoices with as much information as you want. For example, if you typically include the same line items on all your invoices, include those line items in a template. Below are screenshots of the 4 initial templates included in the Invoice Assistant workbook:

Add your logo, change fonts, change colors ... although there are a few things you shouldn't change in the templates, the Vertex42 Invoice Assistant is designed with flexibility in mind and there is almost no limit to the type of customization you could do with the templates. It just depends on how well you know Excel.

Track Invoices Created Using Any Tool

We've designed the invoice manager to allow you to track any invoice, regardless of what tool or template was used to create or send your invoice.

For example, if you are transitioning from a different invoicing solution, you could include your older unpaid invoices in the invoice manager worksheet and then begin creating new Excel invoices using the next invoice #.

Add Other Templates

See a template you really like in the Microsoft Office gallery? If it's a simple template with a worksheet you can move into the Vertex42 Invoice Assistant workbook, you just need to define 3 named ranges (date, due date, total amount) to create invoices using that new template. Adding a few other formulas will allow you to automatically include the customer information as well.

Open VBA Code

We know that there are many customers who are power users with Excel, fully capable of diving into VBA code and adding their own macros. While the code is of course copyrighted, we see no reason to prevent you from viewing all of the VBA code so that you can turn the Vertex42 Invoice Assistant into the tool that is perfect for your company.
