Custom software developer in Delhi
Delhi's wholesale and manufacturing trade runs on phone calls, WhatsApp messages and a ledger that one accountant understands. Custom software here means an order desk that captures a dealer's message, checks stock, raises a GST-ready invoice and reminds the dealer about dues. I build it in stages, with tests and documentation, working remotely from India on the same clock. I have no office in Delhi, so we plan the work on video calls.
Based in India and working remotely: no office in Delhi, and video calls at times that suit you. Delhi is on UTC+5:30 like the rest of India, and I am too, so there is no time-zone difference at all. Corporate offices in Delhi mostly keep a Monday to Friday week, while markets, clinics and coaching centres run Monday to Saturday; I plan calls around whichever your business follows.
Custom software development for Delhi businesses
Start with the order desk. A trader in the old city markets or a maker in Okhla and Mayapuri may receive forty orders a day as free text, photos of handwritten lists and voice notes. An intake screen lets a staff member convert each message into an order in under a minute, with item names matched against the catalogue, stock shown beside each line and a confirmation message sent back automatically. Wrong quantities and duplicate orders are the usual errors, so the system flags an order that looks like one already entered that day. The dealer sees the status through a simple link, not an app they must install.
Dues are the second half of the same system. Outstanding invoices are listed by age, a reminder goes out by WhatsApp or e-mail on a schedule you set, and a payment recorded against an invoice closes it without retyping. I connect this to your accounting software through its export or API instead of replacing it, so your accountant keeps the tool they trust. Invoices carry the GSTIN and the tax breakup the rules require, and I write that logic as tests against sample invoices your accountant has already checked, not against my own assumptions.
Coaching institutes, law firms and chartered accountants in Connaught Place, Karol Bagh and Saket need a different shape. An institute wants enquiries assigned to counsellors and followed up until a seat is confirmed or the lead is closed, with fees, batches and instalment dates in one place. A professional firm wants matters, deadlines and documents tracked so that a statutory due date is never found by accident. Both hold personal data covered by the Digital Personal Data Protection Act, 2023, so access is by role and every change is recorded. Each project begins with a short written scope you sign off before any code is written.
Working with a remote specialist from Delhi
- Time zone
- Delhi is on UTC+5:30 like the rest of India, and I am too, so there is no time-zone difference at all. Corporate offices in Delhi mostly keep a Monday to Friday week, while markets, clinics and coaching centres run Monday to Saturday; I plan calls around whichever your business follows.
- How projects there are usually paid
- Delhi businesses typically pay professionals by bank transfer (NEFT or RTGS) and use UPI for smaller sums. Traders and companies expect a GST invoice with the supplier's GSTIN, and some deduct TDS before paying a technical or professional fee, so those details are best settled in the quote. Local currency: INR.
- Languages
- English, Hindi, Punjabi, Urdu
- Rules that apply
- The Digital Personal Data Protection Act, 2023 covers personal data gathered on enquiry and booking forms, so state why you collect it and take clear consent.

Custom software developer in Delhi: questions
Yes. I would build an intake screen that turns messages into orders, checks stock, sends a confirmation and raises the invoice, working alongside the WhatsApp number your dealers already use.
Usually. I connect through the software's export or official API and test the invoice and GST logic against sample invoices your accountant has verified, so nothing changes in how the books are kept.
No. I work remotely from India with no office in Delhi. Calls and screen-shares happen on the same time zone, and an in-person meeting happens only if you arrange one.
Yes. Enquiries are assigned to counsellors with follow-up reminders, and the same record holds batch, fees and instalment dates, with access limited by role and every change logged.
Look for a process that costs staff hours every week, a spreadsheet nobody dares to touch, or tools that cannot be connected. If a subscription tool already covers most of it, I will recommend that and only build what is missing.
It depends entirely on scope, so I do not quote a number from a title. After the scope document I give a fixed price per stage, or an hourly estimate with a cap, so you can decide stage by stage without a surprise.
No. The work is remote, so I serve Delhi and the wider NCR the same way, and the site can target buyers in other cities and states if your customers are spread out.
