SaaS and product development

SaaS and product development, from first release to scale

SaaS product development is the work of building software that many customers use at once, with their data kept apart, billed by subscription and updated continuously. Restrologic builds and operates such products. Our restaurant platform runs about 300 live outlets and handled about 6 million orders in 85 days.

What is SaaS product development?

SaaS product development means building software that many customers use over the internet, on one shared platform, paid for by subscription. Each customer sees only their own data. The vendor ships updates continuously and runs the system day to day.

It is harder than building one custom application. The platform needs tenant separation, billing, roles, reliable background jobs, monitoring and a plan for upgrades that do not break customers.

What we build

We build the whole product, not a prototype that someone else must finish. A typical scope covers these parts.

What proof do you have?

We run a SaaS product at real volume. The Restrologic POS suite is a point of sale platform for restaurants, built and operated by us.

Measure Figure
Live outlets About 300 (299 production stores, August 2026)
Orders handled About 6 million in about 85 days, March to June 2026
Largest client Natural Ice Cream, about 251 outlets
Hunger Inc Hospitality 6 outlets
Security audit Independent VAPT by a CERT-In-empanelled firm, February 2026, no critical or high findings

The product covers a POS terminal for billing, KOTs, split bills and day open and close, a captain app for waiters, a self-order kiosk, an online-order desk for Swiggy and Zomato, an admin for menus, taxes, staff and offers, about 28 reports with a custom report builder, e-bill, a QR menu and receipt printing. It handles multiple brands and multiple store types in one account: physical outlets, dark stores and cloud kitchens, with GST rules including CGST, SGST and aggregator liability.

Read how this played out for a large chain in our Natural Ice Cream case study.

Outside restaurants, we built the backend, a new operations web app and a new rider app for Zippee, a delivery company. The Zippee case study covers live rider tracking, delivery OTPs and photo proof of delivery.

How does a SaaS build run?

We work in short cycles with a working system at the end of each one. The shape is usually this.

  1. Discovery. We map who uses the product, what they do daily and what would make them pay. We cut the first release to the smallest set that earns its place.
  2. Design of the data model. This step decides whether the product can serve many customers safely, so we do it before screens.
  3. Build in cycles. Each cycle ends with something you can click, running on a real environment.
  4. Pilot. A small group of real users runs the product and we fix what they find.
  5. Launch and operate. We move to production, set up monitoring and backups, and keep shipping.

What makes a SaaS product hold up in production?

The hard parts show up after launch. These are the decisions we make early.

How do we decide what goes into the first release?

A first release should do one job well for a small group of real users. We list every feature the idea needs, then ask of each one: can a customer pay for the product without it? If the answer is yes, it waits. This keeps the first version small enough to launch, and it gives you real usage data before you spend on the second.

We also write down what the product will not do yet. That list matters as much as the build list, because it stops scope from growing unnoticed. Billing, roles and tenant separation usually stay in, since they are costly to add later.

Who is this for?

It is a poor fit if you need a one-off brochure site or a very small internal script. For those, custom software and integrations is usually the better route.

What you get and how we work with you

You get working software in your own repository or ours, as agreed in writing. You get a named point of contact for non-technical matters, Deepak, who runs our day-to-day operations. Meetings are online, on Google Meet or Zoom, and we send written notes after each one.

Next step

Tell us what the product should do for its first ten customers. Contact Deepak with a short description, and we will reply with questions and a proposed first release.

Frequently asked questions

Do you only build for restaurants?

No. Our biggest product is for restaurants because that is where we have run it longest. The same team built a delivery and rider platform for Zippee and a consumer AI app, Vedikshana. The engineering carries across industries.

Can you take over a product that is already live?

Yes. We start with a review of the code, the database and the deployment, then agree what to keep, what to repair and what to rebuild. We do not promise a full rewrite until we have read the code.

Who owns the code?

Ownership follows your written agreement for the engagement. Each project has its own terms, so we settle this before work starts.

Do you run the product after launch?

We can. We run production databases with a replica in a second datacentre, encrypted off-site backups, and round-the-clock monitoring with paging.

How do you handle security?

Tenant separation is designed in from the first table. Our restaurant platform passed an independent security audit by a CERT-In-empanelled firm in February 2026 with no critical or high findings.
