Software Development at N&D Co. is the design and build of custom business software: web applications, CRM systems, mobile apps and internal admin tools. Each project starts with a written agreement covering scope, timeline and price (fixed or hourly), and includes testing, deployment and a post-delivery support window. The service is for small and mid-sized businesses that have outgrown spreadsheets and off-the-shelf tools. N&D Co. is based in Barrackpore, Kolkata, and works remotely with businesses worldwide.

Copying data between spreadsheets and chat threads stops. ### Software that matches your process We build around how your business already runs, so staff do not have to change their habits to fit a generic tool. ### You own the deliverables On full payment, ownership of the final deliverables named in your quote passes to you. When the quote includes the source code, you can host it where you like and hire anyone to extend it. ## What is included ### Requirements document A written record of every screen, user role and business rule the software must follow, agreed before build starts. It is the reference for scope and revisions. ### Web application A browser-based application with login, user roles and the workflows from the requirements document, built with a current framework such as React on the front end. ### CRM system Contact, lead and follow-up tracking with the fields and pipeline stages your sales process uses, plus reminders and basic reporting. ### Mobile app An Android or iOS app for staff or customers, connected to the same database as the web application, with help on Play Store and App Store listing at launch. ### Internal admin dashboard A back-office view for owners and managers: records, permissions, exports and the metrics you asked for in discovery. ### Database and API A structured database and a documented API, so the software can connect to payment gateways, accounting tools or a future app. ### Testing and deployment Functional testing against the requirements document, then deployment to your hosting account or to a provider we set up in your name. ### Handover and documentation Source code in a repository you control, a setup guide and a walkthrough session for your team. ## Software development pricing Every quote is set in writing before work starts, based on the scope we agree in discovery.

We follow up with a written scope, timeline and quote. ### Design Wireframes and a clickable prototype for every screen. You review and we revise; typical projects include two to three revision rounds before development starts. ### Development We build in stages and share a working preview at each stage, so you see progress on real screens rather than in status reports. ### Testing Each feature is checked against the requirements document on desktop and mobile. Bugs found here are fixed before launch. ### Launch Deployment to production, data migration if needed, and a walkthrough for your team. The balance is due before final delivery. ### Support A 7-day post-delivery support window covers minor corrections and technical issues. Ongoing maintenance packages are available separately. ## Who this is for - Business owners running operations on spreadsheets, WhatsApp groups and paper who want one system for the whole team. - Companies whose off-the-shelf CRM or ERP no longer fits, and who want software shaped around their own process. - Founders with a validated idea who need a first working version of a web or mobile product. - Established firms in Kolkata, across India and worldwide that want a remote development team working from a written scope and quote. ## Frequently asked questions **How much does custom software development cost?** Every project is quoted individually after a discovery call, either fixed-price or hourly, and the quote is confirmed in writing before work starts. A 50% upfront payment starts the project and the balance is due before final delivery. The tiers on this page are starting points, not fixed packages. **How long does it take to build custom software?** A Starter tool usually takes 2 to 3 weeks, a Business system 4 to 8 weeks, and a web application with Android and iOS apps 8 to 16 weeks, depending on the number of screens, user roles and integrations. The timeline is agreed in writing before we begin. **What do I need to provide before development starts?** A clear description of the problem, access to the people who will use the software, and any existing data or systems it must connect to. If you have hosting, domain or payment gateway accounts, we ask for access in your name rather than creating new ones. Everything else, from wireframes to documentation, we produce. **Do you build mobile apps as well as web applications?** Yes. We build Android and iOS apps and browser-based web applications, and often both for the same product with a shared database and API. Which one you need depends on where your users are and how they will use the software, and we settle that in discovery. **Who owns the source code after the project?** On full payment, ownership of the final deliverables named in your quote passes to you, with the rights agreed there. When the quote names the source code, we hand over the repository and its documentation with it. We may show the completed work in our portfolio unless you ask us in writing not to. **Do you provide support after the software is launched?** Every project includes a 7-day post-delivery support window for minor corrections and technical issues. After that, ongoing maintenance and new feature work are available as a separate package or billed hourly. If your quote passes the source code to you, you are also free to have another team maintain it. ## Who you will work with N&D Co. is run by its founder, [Nakshatra Ranjan Saha](https://ndcompany.in/team/nakshatra-ranjan-saha) (CEO & Founder), from Barrackpore, Kolkata, West Bengal, India.
