Innila - Traditional Foods E-Commerce
Project Overview
Sister storefront to Airlia on the same ARI platform, serving traditional vermicelli, flours, and grains. Subdomain-isolated brand experience, OTP/Google auth, Razorpay checkout, and automated GST-compliant invoicing.
The Challenge
Adithyaa Ram Industries needed a second, subdomain-isolated brand store for their traditional food line without duplicating infrastructure. The store required OTP/Google authentication, Razorpay checkout, and automated GST-compliant PDF invoicing for B2B buyers.
Our Solution
We extended the Airlia platform architecture into a multi-brand monorepo. Innila runs as a fully isolated subdomain experience sharing the same Prisma/Neon Postgres backend with tenant-scoped RLS. We integrated OTP login via Resend, Razorpay for payments, and a server-side PDF invoice generator that auto-emails GST breakdowns to buyers post-purchase.
export async function generateGSTInvoice(order: Order): Promise<Buffer> {
const doc = new PDFDocument();
doc.text(`GSTIN: ${order.seller.gstin}`);
doc.text(`Invoice No: ${order.invoiceNo}`);
order.items.forEach(item => {
const gst = item.price * 0.18;
doc.text(`${item.name}: INR ${item.price} + GST ${gst.toFixed(2)}`);
});
return bufferFromStream(doc);
