FAQs

How Much Does It Cost to Build an Ecommerce App or Website?

Cost depends on the type (store, B2B portal or marketplace), the features, the integrations and the platforms. A single-brand store costs less than a multi-vendor marketplace. After a discovery call, we send a proposal with a fixed price or a time and material estimate, so you can compare a lean launch with a fuller build.

How Long Does It Take to Develop an Ecommerce App?

A focused store with checkout and payments launches sooner than a marketplace with vendors, payouts and shipping. The timeline depends on your catalog size, integrations and testing. After discovery we give you a realistic range, and we show progress at the end of every sprint so you can plan your launch and promotions.

Should I Build a Custom Store or Use a Ready-Made Platform?

A ready-made platform suits simple stores. Go custom when you need unusual pricing, B2B rules, marketplace features or deep links to inventory and ERP. We tell you honestly which option fits during discovery, even when that means starting with a simpler setup and moving to custom later.

What Is the Difference Between B2B and B2C Ecommerce?

B2C sells to individuals with fixed prices and quick checkout. B2B sells to businesses with bulk orders, custom pricing, approvals and invoices. We build both, and we can run them on one back end if you sell to consumers and businesses, so product and stock data stay in one place.

What Features Does an Ecommerce App Need?

Start with search and filters, product pages, a cart, secure checkout, order tracking, accounts and notifications. Reviews, wishlists and recommendations come next. We help you pick the first release so you can launch sooner, then use real order data to decide which features to add next.

How Do You Keep Payments and Customer Data Secure?

We use secure payment gateways, encryption and role-based access, and we test for common security flaws. Card details stay with the payment provider whenever possible, which reduces your risk. We also plan secure hosting and backups with you, and we log access to sensitive customer and order data.

Can You Connect the Store to Our POS, Inventory or ERP?

Yes. We connect stores to POS, inventory, CRM, shipping and accounting tools through APIs where they exist. We review your tools first and tell you what connects easily and what needs extra work, so your stock counts and orders stay in step across store, warehouse and website.
