I built this because expert witnesses bill $300-600/hr but track time in Excel and invoice in Word. When opposing counsel challenges a $15K fee, there's no audit trail.

ExpertPractice logs time with activity-specific rates and generates timestamped PDF invoices. The math runs through PostgreSQL, not JS floating point. Attorneys can view invoices via a shareable link without creating an account.

Solo project, Next.js + Supabase + Stripe. Happy to answer questions.
