Serving Kolkata, India remotely

CRM developer in Kolkata

Kolkata's year is shaped by seasons: school admissions, Durga Puja, wedding months. A CRM that cannot cope with a sudden surge of enquiries in those weeks fails when it matters most. I build custom CRMs that queue, assign and remind at volume, in English and Bengali. I work remotely from India and have no office in Kolkata.

Based in India and working remotely: no office in Kolkata, and video calls at times that suit you. Kolkata and I are both on UTC+5:30, so there is no time-zone difference and the working day overlaps in full. Many Kolkata offices, schools and clinics work Monday to Saturday, and some corporates Monday to Friday; calls are set around your pattern, including the long Durga Puja holiday period when many businesses slow down.

Custom CRM development for Kolkata businesses

Caterers, banquet halls and wedding services in Ballygunge, Salt Lake and Rajarhat live by the calendar. The CRM treats a date as the centre of every enquiry: a hall is either free or booked on it, a quote expires on a day, and the advance reminder is due a fixed number of days before. Staff see a month view of enquiries, tentative holds and confirmed events, and a hold lapses on its own unless someone confirms it. Photos, menus and quotations are sent by WhatsApp from the record, so what the family received is always visible to the team.

Schools and colleges across Salt Lake and Park Street face an admission window with hundreds of similar questions. The CRM stores each child's class and board, sends fee and date information in Bengali or English and gives each counsellor a daily list of people to call. It avoids promising a seat or a result, as the ASCI code expects such claims to be supportable. The DPDP Act 2023 covers student data, so the form states why details are collected. After the window closes, the same system keeps the waiting list warm for the next intake.

Traders in Burrabazar and manufacturers around Howrah, who sell to buyers across eastern and north-eastern India, use the CRM differently: a catalogue sent by WhatsApp, a price list by e-mail and a reminder to ring after the buyer's market day. Nursing homes in Ballygunge and Kolkata's suburbs use appointment reminders and a missed-call lead list. Bengali words typed in Roman letters are common, so search inside the CRM handles both spellings. I show work at each stage on a staging link, and we talk in your working hours. If a ready-made tool would do the job for less effort, I will say so before any building starts, because a CRM nobody opens helps no one.

Working with a remote specialist from Kolkata

Time zone
Kolkata and I are both on UTC+5:30, so there is no time-zone difference and the working day overlaps in full. Many Kolkata offices, schools and clinics work Monday to Saturday, and some corporates Monday to Friday; calls are set around your pattern, including the long Durga Puja holiday period when many businesses slow down.
How projects there are usually paid
Kolkata businesses mostly pay by NEFT, RTGS or cheque to a bank account, with UPI for smaller sums. Traders and companies expect a GST invoice with the supplier's GSTIN, and some deduct TDS, so I suggest settling invoicing details in the quote. Local currency: INR.
Languages
English, Bengali, Hindi
Rules that apply
The Digital Personal Data Protection Act, 2023 applies to student and patient data collected on enquiry forms, so purpose and consent should be stated clearly.

CRM developer in Kolkata: questions

Yes. The calendar treats a confirmed booking as taking that hall and date, shows tentative holds in another colour and lets a hold expire automatically if nobody confirms it.

Yes. Enquiries are queued, assigned across counsellors and shown with a timer, and automatic acknowledgements go out immediately so families are not left waiting while staff catch up.

Yes. Search is set to match common spelling variants, and templates can be kept in Bengali script, Roman Bengali and English, so staff can find a person however the name was typed.

Yes. A catalogue or price list can be attached to a message from the lead's record, sent by WhatsApp or e-mail, and the follow-up reminder is set at the same moment.

Buy when a standard tool covers your process and team size. Build when your sales steps are unusual, leads come from several channels, you need strict separation between clients or licence costs are climbing. I review your process first and give an honest recommendation.

A focused first version, with lead capture, a pipeline, tasks and a couple of reports, usually takes several weeks. Multi-tenant systems, many integrations or heavy automation take longer. I give a schedule with the written scope before work begins.

Yes. Bengali is my native language, along with fluent Hindi and professional English, so I can discuss the project and write or edit Bengali page and ad copy myself.
