What technology does a retail or D2C brand need?
A growing retail or D2C brand needs a storefront and app that convert, an inventory and order system that stays in sync across every channel, and customer data it can act on through WhatsApp and campaigns. Stack18 delivers these on one connected foundation, either from ready-made Commerce OS and Customer OS or as custom software.

Retail & D2C questions.
Can you connect our website, app and ERP?
Yes. We build or integrate them on one data foundation so stock, orders, customers and accounts stay in sync, as we did for a ₹100+ crore D2C brand in three months.
Do you integrate marketplaces, payment gateways and couriers?
Yes. Channel, payment and logistics integrations are part of the scope, and we confirm the exact list in the fixed-price first step.
Should we start with a ready-made system or custom software?
Most brands start with Commerce OS, from ₹2.8L with launch in 3–4 weeks, then add custom features where their process is different.
Will it work with UPI and WhatsApp?
Yes. UPI payments and WhatsApp order and support journeys are built in.
How do you prepare for sale-day traffic?
We plan capacity for festive and sale-day peaks and test the stack before launch.
Do you build software for Retail & D2C businesses in Jaipur and across India?
Yes. Stack18 is headquartered in Jaipur, Rajasthan, and works with Retail & D2C businesses across India. You get a free 30-minute call, a fixed-price first step and working software every week, so the engagement works the same whether you are in Jaipur or elsewhere.
