What is Local Shop API & Payment Gateway Integration?

Sabka Saathi builds an integration for local shops in India. Connecting your system to the payment gateways, logistics partners, government portals and third-party tools it needs to talk to. For local shops specifically, that means counter billing fast enough not to slow the queue, customer credit and udhaar ledgers that reconcile, and item-wise sales so you stock what actually moves. Typical delivery is 2–6 weeks at ₹15,000 – ₹1,20,000+, built on Node.js, TypeScript, PostgreSQL, and delivered remotely to shop owners and counter staff anywhere in India.

Built for Local Shops

Why local shop projects are different

API & Payment Gateway Integration for local shops is not the same project as it is for any other sector. In local shops, billing happens with a queue waiting, and the day's accounts get worked out from the cash drawer after closing. 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 integration around it instead.

Most local shops 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. Shop owners and counter staff tell us how the work happens today — including the parts that only exist in someone's head — and the integration is shaped to that. Data stops being re-typed between systems, and money stops being reconciled by hand.

The problems this solves

What local shop teams actually struggle with

Problem 01

Handwritten bills mean no record of what actually sold

Razorpay, PayU, Cashfree, Stripe and UPI integration — built into the integration rather than bolted on afterwards.

Problem 02

Credit given to regulars is tracked in a notebook, or in memory

Webhook handling that survives retries and duplicate events — built into the integration rather than bolted on afterwards.

Problem 03

You cannot tell which items earn and which just occupy shelf space

Settlement and refund reconciliation against your own records — built into the integration rather than bolted on afterwards.

How we deliver

From first call to handover

We start with a discovery call to map how your local shops 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 2–6 weeks for a typical local shop project, and we hand over source code, documentation and training.

Questions

Local Shop API & Payment Gateway Integration FAQs

How much does Local Shop API & Payment Gateway Integration cost in India?

Local Shop API & Payment Gateway Integration from Sabka Saathi typically costs ₹15,000 – ₹1,20,000+, depending on scope. A focused build covering razorpay, PayU, Cashfree, Stripe and UPI integration sits at the lower end; a full system including logistics, SMS, WhatsApp and GST portal integrations 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 integration for local shops?

A typical local shop integration project takes 2–6 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 local shops need an integration specifically?

Because billing happens with a queue waiting, and the day's accounts get worked out from the cash drawer after closing. The direct consequence is one most local shops will recognise: handwritten bills mean no record of what actually sold. A generic product does not solve that — it needs counter billing fast enough not to slow the queue. Data stops being re-typed between systems, and money stops being reconciled by hand.

What technology is used to build it?

We build on Node.js, TypeScript, PostgreSQL, Redis, Razorpay, Stripe. 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 local shops outside major cities?

Yes. Delivery is remote — discovery calls, design reviews and weekly builds all happen online — so we work with local shops 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.
