One platform for running online assessments, hiring on skill, selling subscriptions, and selling digital products.
What we build
Most people who run online tests also sell something - study material, a course, a membership. Most people selling digital work eventually want to assess someone. Those two jobs are usually served by two unrelated products with two bills, two logins, and no shared record of who bought what or who sat which paper.
TheBlueMustard puts both on one account. A coaching institute can run a mock test series and sell access to it. A hiring team can screen candidates on skill. A creator can sell files, or sell recurring access to them. The same identity, billing, invoicing and entitlement layer sits underneath all of it.
It is built for India first: pricing and settlement in Rupees through Razorpay, UPI and UPI Autopay as first-class payment methods, and GST invoicing that produces documents a buyer’s accountant can actually file.
A mock test series is the same paper delivered to a batch, marked consistently, and turned into something a student can act on. That is the workflow this is built around.
Screening on skill means every candidate answers the same questions under the same conditions, and you compare the results rather than the impressions.
If you already make templates, notes, presets, fonts, code or courses, the missing part is usually everything after "here is the file": payment, delivery, receipts, and getting paid out.
Selling the same work twice is harder than selling continued access to it. A subscription plan makes access the product and lets the platform enforce it.
How it is built
The parts that are load-bearing when money and exam results are involved.
Powered by Razorpay - credit cards, debit cards, UPI, net banking and popular wallets, in Indian Rupees. Card details never reach our servers.
Sequential invoice numbering, CGST / SGST / IGST tax lines, credit notes and refunds - ready for B2B customers to file.
Every purchase mints a licence key; every subscription grants an entitlement that is checked on every download and test attempt.
Immutable audit trails for sensitive actions, short-lived signed download URLs, per-IP rate limits, and platform-owner kill switches.
Clerk handles sign-in, with optional two-factor authentication. All connections are encrypted in transit over HTTPS and WSS.
Product files are stored on AWS S3 with server-side encryption, checksummed on upload, and never served from a public URL.
