What's the most annoying scaffolding you keep rewriting for B2B tools?

Hey Product Hunt 👋

I'm launching InvoiceFlow Starter Kit on October 8th — a React + Expo frontend for B2B invoice tools.

Before I launch, I want to hear from other developers:

When you're building a B2B data tool, what part of the scaffolding do you hate rewriting the most?

For me, it's always the verification/validation UI. Upload a file → parse it → show the result → let the user fix mistakes before saving. It's boring, repetitive, and every project needs it.

That's why I built the kit: it ships with a full invoice flow — upload → AI extract → three-check verification (amount / date / duplicate) → line items grid → ledger + CSV export.

Curious what you all hate building the most. Reply below and I'll share early access before launch day.

See you on October 8th ! 🚀
