ProofKit

Proof approvals lived in email threads.

[Describe the printing client's situation: how proofs were sent and approved before, what went wrong — missed changes, delays, reprints — and what it cost them.]

A drop-in widget, built like payments infrastructure.

Instead of another portal customers have to log into, ProofKit embeds into the print company's existing order page — the same way a payment form does.

• Multi-tenant by design — PostgreSQL row-level security keeps each print company's data isolated.
• Signed order tokens — JWTs tie every proof link to one order, so customers approve without an account.
• India-first billing — Razorpay Subscriptions for plans, Resend for proof and approval emails.
• Three focused codebases — backend, embeddable widget and marketing/web app, each deployed on its own.
