The core of an invoicing system powered by Invoice Manager for Excel is an add-in program that runs inside Microsoft Excel. On the front-end, you see and work with an Excel-formatted invoice template with many buttons on the task pane and ribbon, like "Customers", "Products", and "Invoices". The add-in program connects the invoice template with a backend database for storing and organizing data.
With this architecture you benefit from both two mature technologies.
All the powerful Microsoft Excel tools are all available to you for further customizing the invoice template.
You may have very special requirements about the invoices you create. Invoice Manager for Excel allows you to use your familiar Excel tools to adjust fonts, colors, borders, patterns, and even formulas to do calculations and create relationship between cells/fields.
If you prefer to put a field on another location, or don't need it at all, you can do this by simply dragging and dropping it.
If you need new fields to further detail the goods and services you provide, use custom files.
