More than 4 custom fields


I am checking our invoice ninja. We need some additional custom fields for products and for customers.

e.g. for products I might need a “category” of the product and a “unit type” like hours, kg, years…

At a first glance it looks like as if it is only possible to add 4 custom fields? Is it possible to add more than 4 custom fields?

Thanks a lot


Sorry, it isn’t supported

Are there any plans to add support for more custom fields in the future?

We don’t have immediate plans to support more
