Where online selling breaks down
Six e-commerce problems a better store solves.
Getting a store online is easy. Running one profitably, with accurate stock, smooth checkout and invoices that match your books, is where most platforms fall short.
Stock that doesn't match reality
The website, the warehouse and the marketplaces all show different quantities, so you oversell or undersell.
Manual invoices and GST headaches
Orders are re-keyed into accounting software and GST invoices are prepared by hand every evening.
Platform fees eating your margin
Monthly subscriptions, transaction fees and paid apps add up on hosted store builders.
A template that can't fit your model
Subscriptions, B2B price lists, sell-by-weight or multi-vendor rules don't fit an off-the-shelf theme.
Slow catalogue pages on mobile
Large product images and heavy apps make category pages crawl on phones, where most shoppers browse.

Catalogue & storefront
A catalogue that helps shoppers find the right product fast.
Category pages load quickly on mobile, filters match how your customers actually choose, and search understands product names, codes and common misspellings. This storefront Sysfo built for ScrapApp sells materials by grade and weight, the kind of custom catalogue logic a generic template struggles with.
- Category, brand, price and attribute filters
- Fast search with suggestions and typo tolerance
- Variants, bundles, sell-by-weight and B2B price lists
- SEO-friendly category and product URLs with schema markup
Product pages & checkout
Product pages that answer questions, and a checkout that converts.
Clear photos, pricing, stock status and delivery information sit above the fold, so buyers don't need to ask. Checkout is reduced to as few steps as possible, with guest checkout, address autofill, saved payment options and every popular Indian payment method, plus a clear GST and freight summary before payment.
- Razorpay, PayU, Cashfree, PhonePe or CCAvenue gateways
- UPI, cards, net banking, wallets, EMI and COD
- Guest checkout, OTP login and saved addresses
- Coupons, offers and cart-recovery emails or WhatsApp messages
Subscriptions & wallets
Built for repeat purchases, not just one-off orders.
Groceries, dairy, water, pet food and many other categories sell best on a schedule. Our milk delivery platform shows how: customers top up a prepaid wallet, set daily or alternate-day subscriptions, and pause or skip deliveries themselves, while refunds and charges post automatically to the wallet ledger.
- Daily, weekly, alternate-day and custom schedules
- Prepaid wallets with top-ups, cashback and refunds
- Self-service pause, skip and holiday mode
- Automatic reminders before the balance runs low
Order & inventory management
One admin panel for orders, stock and deliveries.
Behind every storefront is the back office your team uses all day. We build admin panels where orders flow through clear statuses, stock updates in real time across warehouses and channels, and returns, cancellations and delivery assignments are handled in a few clicks, with role-based access for each team.
- Order pipeline with statuses, notes and bulk actions
- Multi-warehouse stock, low-stock alerts and purchase entries
- Returns, refunds and cancellations with an audit trail
- Delivery-partner assignment, routes and proof of delivery
GST invoicing & reports
GST invoices, payments and reports that match your books.
Every order generates a GST-compliant invoice with the right HSN codes, place of supply and tax split, and credit notes are raised automatically for returns. Payment reconciliation, sales, tax and product reports are ready for your accountant, with exports to Tally or your ERP so nothing is typed twice.
- GST invoices with CGST, SGST and IGST split
- Credit notes, e-invoicing readiness and HSN summaries
- Gateway and COD payment reconciliation
- Sales, tax, product and customer reports with exports

FAQ
E-Commerce Website Development — frequently asked questions
What does e-commerce website development include?
E-commerce website development at Sysfo covers catalogue and UX planning, storefront and checkout design, development of the store and its admin panel, payment gateway, shipping and SMS or WhatsApp integrations, GST invoicing, inventory and order management, SEO set-up, testing with real orders, launch and staff training. Hosting and ongoing support are available on a monthly plan.
How much does an e-commerce website cost in India?
It depends on your catalogue size, business model, such as single brand, B2B or multi-vendor, the integrations you need and whether we build fully custom or customise Sysfo's ready e-commerce platform. After a free scoping session we give you a fixed, itemised quote, so the full cost is clear before any development begins.
How long does it take to build an online store?
A customised store on Sysfo's ready e-commerce platform can launch in a few weeks. A fully custom online store typically takes six to twelve weeks: two to three for catalogue and design, four to six for development and integrations, and one to two for product loading, testing and launch. Marketplaces and complex B2B portals take longer.
Custom store, WooCommerce or Shopify: which should I choose?
Hosted builders like Shopify are quick to start but add monthly and app fees and limit custom logic. WooCommerce suits smaller catalogues alongside a WordPress content site. Custom e-commerce website development makes sense when you need subscriptions, B2B pricing, marketplace rules, deep ERP integration or zero platform fees. We'll recommend the option that fits after scoping.
Which payment gateways can you integrate?
We regularly integrate Razorpay, PayU, Cashfree, PhonePe, CCAvenue and Stripe, supporting UPI, debit and credit cards, net banking, wallets, EMI and cash on delivery. Card data is handled by the PCI-DSS-compliant gateway rather than stored on your server, and we set up automatic payment reconciliation in the admin.
Can you build a multi-vendor marketplace?
Yes. We build marketplaces with seller registration and KYC, vendor dashboards, product approval, commission rules, split payments and payouts, plus order routing to each vendor. You can start from Sysfo's multi-vendor e-commerce software and customise it, or we can build a marketplace from scratch for unusual business models.
Will the store generate GST invoices and work with Tally?
Yes. Every order can produce a GST-compliant invoice with HSN codes and the correct CGST, SGST or IGST split, with credit notes for returns. We can export sales and tax data to Tally or integrate directly with your ERP, so orders don't need to be keyed in again by your accounts team.
Do you also build mobile shopping apps?
Yes. We build Android and iPhone apps or installable progressive web apps that share the same catalogue, cart, customer accounts and admin as your website. Many clients launch the website first, then add an app once repeat customers ask for one. Our mobile app and mobile web app teams handle these.
Do you provide e-commerce website development outside Lucknow?
Yes. We are based in Lucknow and provide e-commerce website development for brands, manufacturers and retailers across India and abroad. Scoping, design reviews and weekly demos happen over video calls, and you can place test orders on the staging store at any time.
