Freelancers: what breaks first after the proposal?

I’m building StackKit, a lightweight Notion-ready client pipeline for freelancers. The goal is simple: capture the last conversation, assign one next action and date, keep scope, files, and invoices beside the record, and review stale leads weekly.

For your workflow, where do things usually fall apart after a proposal—follow-up, scope, handoffs, or invoicing? I’d love to learn what you’ve tried and what you wish your system handled better.
