Introducing our H5 App Catalog

We’re excited to announce a new product offering: H5 app catalog.

We’re building a collection of easy-to-install, easy-to-use H5 apps that solve common user problems directly inside M3.

What is an H5 app? An H5 app (sometimes called an SDK app) is a web app that runs inside your M3 instance and integrates seamlessly with the user experience. No extra login, no separate system, just a clean extension of what your users already work with.

We’re starting with four apps:

CRS275 Line Charges

MMS200 Item Management

OIS017 Price Lists

OIS005 Customer Items

With more to come in the future.

For 5000 EUR per year, you get access to all of these apps, every new app we release, all updates, and the ability to request features or even suggest new apps you’d like us to build.

And right now, if you sign up for Loupe (also 5000 EUR/year), we’re including one year of the H5 app catalog for free.
