eCommerce and marketplace development behind the storefront

For retailers, brands and platform founders whose online sales depend on more than a nice storefront. We build the parts behind it: seller management, stock, payments, recurring billing, support desks and the logistics that get orders delivered.

What happens after the buy button

A customer sees a product page and a checkout. Behind them sits a chain of systems: payment confirmation, stock reservation, an invoice, a pick list, a courier booking, a tracking link, and a support queue for when something goes wrong. If any link is manual, orders slow down as volume grows. This group of services covers each of those links, whether you sell your own products, host other sellers, or bill customers on a subscription.

You rarely need all of it at once. A new brand can often start on Shopify or WooCommerce with standard apps and add custom pieces only where the business is unusual. Larger operations may need a marketplace engine, warehouse apps or an ERP link built properly from the start. We help you decide which parts to buy, which to configure and which to build, and our ready-made products such as InventoX can cover some of the ground.

How businesses use it

Brand outgrowing its plugins

A direct-to-consumer brand on Shopify adds an ERP sync app, Razorpay and PayPal checkout, and a WhatsApp support inbox linked to order data.

Regional grocery marketplace

Local stores join as sellers, stock updates come from their billing counters, orders are split by store and riders are assigned through a delivery app.

Subscription business with physical deliveries

Renewals create charges and packing orders together, the warehouse picks by subscriber, and the support desk sees billing and shipment history in one view.

How we approach eCommerce & Marketplace Solutions

  1. Map the order journey — We follow an order from checkout to delivery and refund, marking which steps are manual, slow or error-prone today.
  2. Buy, configure or build — For each gap we compare existing apps, our own products and custom code, with honest notes on running costs.
  3. Build in connected stages — Each piece is delivered with demos and linked to the others through APIs, so data is entered once.
  4. Launch, then maintain — After testing and launch, an optional maintenance plan can cover platform updates, gateway changes and small improvements as you grow.

Questions about eCommerce & Marketplace Solutions

Do I need a custom platform, or will Shopify or WooCommerce do?

For many businesses selling their own products, Shopify or WooCommerce is the sensible base, and custom work should be limited to what they can't do. A fully custom platform is justified for marketplaces with complex seller rules, heavy trade ordering, or unusual business models where you would otherwise fight the platform every day. We will tell you which side of that line you are on.

Which of these services should we start with?

Start where money or time leaks most. If orders are lost between payment and fulfilment, fix the payment integration and webhooks. If stock counts are unreliable, start with inventory. If customers keep calling for updates, a support desk with tracking links helps. A short call about your current setup is usually enough to agree the first piece of work.

Can these systems connect to our accounting software?

They can. Orders, payments, refunds and payouts can flow into Tally, Zoho Books, QuickBooks or Xero, or into an ERP. The important work is agreeing the mapping with your accountant: which ledger each fee, tax and discount goes to, and how gateway settlements are matched to bank credits. Getting that right early saves painful clean-ups at year end.

Do you work with businesses outside India?

We do. The head office is in Raipur, Chhattisgarh, with a branch in Bhopal, and Jain Software Inc is based in Newark, New Jersey. Clients outside those cities are served remotely through calls, video meetings and WhatsApp. Gateways, taxes and couriers are set up for the market you sell in, such as Stripe and VAT for a UK store rather than the Indian defaults.

How is a project across several of these systems priced?

Each part is scoped separately, because a payment integration and a marketplace engine are very different jobs. We usually propose a first stage that delivers something useful on its own, then price later stages once you have seen it working. Everything starts with a call, followed by a written proposal and quote; nothing is fixed until you have read and agreed it.
