什么是 InvoiceProof？
InvoiceProof is invoice insurance for freelancers, contractors and small business owners. Every invoice gets a tamper-evident audit trail, IP logging, e-signatures, and a Chain of Custody document you can hand a small claims court, not just a "read receipt." When a client disputes, you have cryptographic proof they saw and agreed.
