Serving Mumbai, India remotely

E-commerce website developer in Mumbai

Mumbai shoppers expect an order to arrive quickly, pay by UPI in seconds and return it without an argument. I build online stores for Mumbai brands on Shopify or a custom Next.js storefront, then run the Google Shopping, Performance Max and Meta catalogue ads that feed them. I work remotely from India on the same clock, with no office in Mumbai.

Based in India and working remotely: no office in Mumbai, and video calls at times that suit you. Mumbai and I are both on UTC+5:30, so there is no time-zone difference and the whole working day overlaps. Most offices in Mumbai work Monday to Saturday, or Monday to Friday in larger corporates, and I can schedule calls around either pattern, including early or late slots that avoid the long commute hours.

E-commerce website development and e-commerce advertising for Mumbai businesses

The first problem on most Mumbai stores is that the catalogue was built for a showroom and not for a phone. Fashion and accessories labels based around Andheri and Lower Parel often carry hundreds of variants in size and colour, and a single parent product hides the one variant that sells. I rebuild the structure so each colourway has its own images and its own feed entry, sizes show real stock, and a shopper can filter on a narrow suburban connection without waiting. Product photography is compressed and served in modern formats, and the first screen is tested on a mid-range Android handset, because that is the phone most of your buyers actually hold.

Checkout is where Mumbai orders are won. I set up UPI, cards, net banking and wallets through an Indian gateway such as Razorpay or Cashfree, add cash on delivery only where margins can absorb returns, and write delivery estimates that take pin codes into account, because a monsoon week and a Bhiwandi dispatch delay are facts of life here. For jewellery and gifting sellers near Zaveri Bazaar, I add clear making and metal information, certification details and insured shipping notes, since a high-value basket needs reassurance more than a discount. Every order carries a GST invoice in the format your accountant expects.

Advertising on this store has to respect how expensive Mumbai auctions are. Shopping and Performance Max run from a cleaned Merchant Center feed with titles in the order shoppers type them, and budget is split by product group so profitable lines are not starved by weak ones. Meta catalogue campaigns retarget visitors who viewed a kurta or an anklet and left, and creative is tested against cost per purchase and not clicks. I average 9 to 12 times return on ad spend on e-commerce accounts, a figure from specific accounts and not a forecast, and I plan your budget from your own margin and your return rate.

Time zone
Mumbai and I are both on UTC+5:30, so there is no time-zone difference and the whole working day overlaps. Most offices in Mumbai work Monday to Saturday, or Monday to Friday in larger corporates, and I can schedule calls around either pattern, including early or late slots that avoid the long commute hours.
How projects there are usually paid
Mumbai companies commonly settle professional fees by NEFT or RTGS to a bank account, with UPI used for smaller amounts. Registered businesses expect a GST invoice, and many corporate and financial-services clients deduct TDS before paying, so it helps to agree the invoicing details in the quote. Local currency: INR.
Languages
English, Hindi, Marathi, Gujarati
Rules that apply
Property advertisements in Maharashtra are expected to show the MahaRERA registration number of the project, which affects landing pages and ad copy.

E-commerce website developer in Mumbai: questions

Yes. I connect UPI and cards through an Indian payment gateway and add cash on delivery with limits by pin code or basket value, so return-to-origin losses do not eat the margin on risky orders.

I give each colourway its own images, URL and feed entry, show live stock per size, and group variants in Merchant Center so one slow seller does not hide the good ones, then report revenue by product.

No. I work remotely from India with no office in Mumbai, and we use video calls, a shared task board and a staging link at each stage. An in-person meeting happens only if you arrange it.

Shopify suits most stores with standard products, payments and shipping, and it saves build time. A custom storefront makes sense for unusual pricing, complex catalogues or a design that a theme cannot deliver. I recommend by your needs and say what each option costs in effort and flexibility.

Yes. Building and advertising are one workflow for me. I run Google Shopping, Performance Max and Meta catalogue campaigns, and I can do the ads alone if you already have a store or an agency builds the site.

No. I work remotely from India and do not run a Mumbai office. Calls, screen-shares and WhatsApp cover almost everything, and an in-person meeting is possible only if you arrange it.
