What is Retail & E-commerce E-commerce & Marketplace Development?
Sabka Saathi builds an online store or marketplace for retail and e-commerce businesses in India. Your own storefront — or a multi-vendor marketplace — where you keep the customer relationship and the margin. For retail and e-commerce businesses specifically, that means one stock figure shared by store, website and marketplace, your own storefront where the margin stays with you, and order and returns handling through to delivery. Typical delivery is 6–14 weeks at ₹40,000 – ₹4,00,000+, built on Next.js, Node.js, PostgreSQL, and delivered remotely to store owners and online sellers anywhere in India.

Why retail & e-commerce projects are different
E-commerce & Marketplace Development for retail and e-commerce businesses is not the same project as it is for any other sector. In e-commerce & retail, you sell across a shop counter, a marketplace listing and a WhatsApp catalogue at the same time, and stock has to be right in all three. That single fact changes what the software has to get right — and it is the thing generic, off-the-shelf products are least willing to accommodate. We build an online store or marketplace around it instead.
Most retail and e-commerce businesses do not fail to adopt software because they dislike technology. They fail because the product on offer was designed for a different business and asks them to change their process to suit it. We start from your process. Store owners and online sellers tell us how the work happens today — including the parts that only exist in someone's head — and the online store or marketplace is shaped to that. You stop paying 20–30% of every order to a platform that owns your buyer's data.
What retail & e-commerce teams actually struggle with
Marketplace commissions eat the margin you priced for
Catalogue, variants, pricing rules and inventory sync — built into the online store or marketplace rather than bolted on afterwards.
Online and offline stock disagree, so orders get cancelled
UPI, card, netbanking and cash-on-delivery checkout — built into the online store or marketplace rather than bolted on afterwards.
Customer data lives with the marketplace, not with you
Order, shipping and returns workflow through to delivery — built into the online store or marketplace rather than bolted on afterwards.

Technology we build it on
From first call to handover
We start with a discovery call to map how your e-commerce & retail operation runs today. You then see a clickable prototype before development is committed, so the shape of the thing is agreed while changing it is still cheap. Development runs in weekly builds you can open and use — not a black box that reappears at the end. Delivery takes 6–14 weeks for a typical retail & e-commerce project, and we hand over source code, documentation and training.

Retail & E-commerce E-commerce & Marketplace Development FAQs
How much does Retail & E-commerce E-commerce & Marketplace Development cost in India?
Retail & E-commerce E-commerce & Marketplace Development from Sabka Saathi typically costs ₹40,000 – ₹4,00,000+, depending on scope. A focused build covering catalogue, variants, pricing rules and inventory sync sits at the lower end; a full system including multi-vendor onboarding, commission and settlement, where needed sits at the upper end. We quote a fixed price against an agreed scope after a free discovery call, so there is no hourly billing surprise.
How long does it take to build an online store or marketplace for retail and e-commerce businesses?
A typical retail & e-commerce online store or marketplace project takes 6–14 weeks from discovery to launch. You see a working prototype in the first two weeks and weekly builds after that, so progress is visible throughout rather than only at the end.
Why do retail and e-commerce businesses need an online store or marketplace specifically?
Because you sell across a shop counter, a marketplace listing and a WhatsApp catalogue at the same time, and stock has to be right in all three. The direct consequence is one most retail and e-commerce businesses will recognise: marketplace commissions eat the margin you priced for. A generic product does not solve that — it needs one stock figure shared by store, website and marketplace. You stop paying 20–30% of every order to a platform that owns your buyer's data.
What technology is used to build it?
We build on Next.js, Node.js, PostgreSQL, Razorpay, Shiprocket API, Redis. These are mainstream, well-documented technologies chosen deliberately so that any competent developer can maintain the system later — you are not locked into us. Source code and documentation are handed over at project close.
Do you work with retail and e-commerce businesses outside major cities?
Yes. Delivery is remote — discovery calls, design reviews and weekly builds all happen online — so we work with retail and e-commerce businesses across 258+ cities in 36 states, including district towns and smaller centres, on the same terms as metro clients.
Can it integrate with the software we already use?
Usually yes. We integrate with GST billing tools, Tally exports, payment gateways, WhatsApp Business API, logistics partners and most systems that expose an API or a file export. Where a system does not, we plan a migration path rather than forcing you to run both in parallel indefinitely.
