Show HN: Self-hosted business software you can extend with Python modules

Celerp is inventory and accounting software that you can install and run with:

`pip install celerp && celerp init`

It launches a web app with bundled PostgreSQL. Other computers on your LAN can use it through their browsers. There are also desktop installers for Windows, macOS, and Linux.

New modules can be built and imported without forking the repo, so industry-specific workflows and integrations don't need to become part of the core. I've spent about 20 years building ERP systems for factories, wholesalers, and other industries. Celerp is an attempt to turn what I've learned into something simpler to deploy, self-host, and extend.

On install, users can choose from 16 industry presets that load the relevant modules and configuration. Many fields can also be edited directly in place, closer to a spreadsheet than a traditional ERP screen.

My thesis is that over the next few years companies will increasingly want more control over their infrastructure and business data. I'm hoping Celerp can make that practical without bringing back the complexity traditionally associated with self-hosted deployments.

I’d especially like feedback on where local/self-hosted business software breaks down in practice, how to get it into SMEs without relying on implementers, and what it would need to support your own business.
