  • hundreds of professional invoice templates,
  • intuitive and easy-to-use layout,
  • automatic invoice numbering,
  • customizable form layout,
  • custom fields,
  • define cell relationships by using Excel formulas,
  • easily generate and send PDF invoices

Invoice Manager for Excel is released in two editions or release channels: the desktop edition (sold by ourselves via PayPal) and the Microsoft Store edition.

No matter which edition you use, you can always download and use our customized invoice templates for free.

If you have very special requirements, we can also offer the service of creating a customized template. For simple customization, we can do it for free. For complex requirements, we may need to ask for a service fee. Please send us your requirements as detailed as possible. We’ll let you know whether we can create the custom form for you and, if it is possible, what the price is.

The two editions share exactly the same invoice template and database file format. That is, you can move templates and databases from one system to another without making any additional modifications.

Invoice Manager (Lite) is a free Excel web add-in app that helps you create invoices easily with more than 400 free Excel invoice templates. Although not as powerful as Invoice Manager for Excel, it does save you time on invoicing.

  • Click the "Clear & New" button to clear the template so that it is ready for your next new invoice.
  • Fill in the invoice date automatically (optional).
  • Automatic invoice numbering (optional).

Invoice Manager (Lite) saves all the setting values to the Excel template itself. This means:

  • Each template could have its own settings that differ from the settings of other templates, including the automated invoice numbering.
  • If a template is opened with Excel for Windows desktop, you have to save the template in order to persist the settings; If a template is opened with Excel for Office 365, by default, the workbook file is saved automatically unless you turn "Auto Save" off.

All the templates here on UniformSoftware.com work with Invoice Manager (Lite). With the help of Invoice Manager Lite, you can easily build an online invoice creator that runs inside a web browser. To find out the detailed steps involved, see Make Your Own Free Online Invoice Creator.
