Hetackling SAP supply chain pain. Got advice?

Hey folks, We’re a small startup currently based in the UK, relocating to San Francisco next month. Our focus: building smarter supply chain modules that fix the real pain points in SAP environments – especially around public procurement, supplier risk scoring, tender analytics, and automated matching between vendors and government contracts.

We’re now moving toward integrating what we’ve built into SAP ecosystems – starting with Ariba and SRM-style modules. The challenge: SAP is massive, complex, and… let’s be honest, not always friendly to innovation.

Anyone here with experience working with SAP integrations, procurement workflows, supplier risk engines, or tender-based sourcing strategies? We’d love to hear your insights, warnings, success stories, or even just “watch out for that edge case” tips.

Also curious – if you've ever hacked around SAP, seen homegrown fixes, or built tools that sit on top of it, how did you go about it?

Thanks in advance – happy to share what we’ve learned too!
