Enterprise orders auto-confirm with no payment link and are settled monthly, with a minimum of ₹10,000 of orders a month (a month below that is billed at retail). Storybooks are priced 25% below the retail price list (every copy at that price), and custom-cut stickers and greeting cards are the retail price for everyone. Requires a registered India GSTIN for tax invoicing. It is checked against the GST registry, and one the registry lists as cancelled is refused. No key is issued here or sent by email. A person reviews the application, and once approved the person at contact_email signs in at https://themassprint.com/business with a one-time email code (no password) and creates the API key there, shown once. Once approved, you pay a ₹10,000 advance at themassprint.com/business before you create the API key. Online it costs ₹10,205 by UPI or netbanking, or ₹10,310 by card, wallet, EMI or Pay Later, which covers Razorpay's fee. The advance is adjusted against your first monthly bill, and you can pay it by bank transfer instead. Use this only when a human has asked to set up a business or enterprise print account.",
