Catalogue SaaS for Instagram and WhatsApp sellers — upload products once, get a branded storefront link, and take enquiries on WhatsApp instead of re-sending the same photos in DMs.
A boutique with 150 dresses and six thousand Instagram followers answers the same DM all day: price, colours, size M, send designs. The seller re-sends the same photos by hand, dozens of times. A full ecommerce build is far too heavy for them, and a WhatsApp catalogue is far too thin — so Product Share sits in the gap: one link that holds the whole range.
Instagram-first sellers
One link to drop in a bio or a reply, instead of re-sending the same photos and prices every day.
Their customers
Browse the real range — sizes, colours, prices, availability — and ask about one item without making an account.
Sellers who are growing
To know which products people actually open, and where the traffic came from — which Instagram never tells them.
The whole product is built around a single shareable address per seller. Every design decision follows from that: the storefront has to load fast on a phone, read well from an Instagram bio, and show the entire range without the customer signing up for anything.
Each store, category and product is a real rendered route rather than a client-side shell. That makes catalogues findable outside Instagram, which turns every seller's storefront into its own small source of traffic.
Sellers upload straight from their phones, so originals arrive at five to ten megabytes. Each upload is resized into thumbnail, card and product widths with the original kept aside, and served from object storage behind a CDN. On mobile data this is the difference between a catalogue that opens and one that gets closed.
Enquiries are wa.me deep links carrying a pre-composed message with the product name, SKU and price. No API onboarding, no per-message cost, and it works from the first day a seller publishes. The business API is a later problem, not a launch blocker.
Razorpay subscriptions with webhook-driven entitlement: activation, renewal, cancellation and failed payment each move the store's plan state. Product limits and branding removal are enforced from that state on the server rather than hidden in the dashboard UI.
Free stores are capped and carry a Powered by Product Share line. Every free catalogue shared into a WhatsApp group is a link back, which makes the cheapest plan the acquisition channel.
Checkout, delivery and order management were left out on purpose. Adding them turns the product into a small, worse Shopify. Catalogue, sharing, WhatsApp and analytics is a complete thing to sell on its own — and it is what the customer actually asked for.
