We built a lot of the custom ERP related systems outside of our ERP. Leaving the financials to the big boys and just talk to the ERP. It's working really well.

We recently replaced Oracle financials for two of our customers-mid size manufacturers doing around $10B/yr in revs. We’re pretty small so grateful they trust us with that level of work.

agree. it's very impressive how SAP maintains multiple ledgers for different regulations in different countries. i'm not going to replace that any time soon. i think even tesla uses SAP for accounting, but something like this for the rest.

Is there a reason for such an arrangement? Why would Tesla not use SAP as their backbone ERP too?

Customising SAP is like setting money on fire but the core of it is rock solid.

Yeah, but we're talking Tesla here, not some run-of-the-mill carmaker. In fact, given SAP's rep in German manufacturing, they might have even been a net positive for Tesla.

Does the ERP allow you API access, or do you need to do CSV upload/download?

we give people access to the same supabase API as us, but it's scoped to their company with RLS. the docs are autogenerated: https://x.com/barbinbrad/status/1873043714454811100

you can use the API from inside the codebase, or outside of it: https://github.com/crbnos/carbon?tab=readme-ov-file#api

API and direct database access.
