Custom E-Commerce Development: A Commission-Free, Integrated Sales Platform You Own

I build an e-commerce site that is entirely yours, with a product structure tailored to your industry plus payment, shipping and marketplace integrations.

Quick answerCustom e-commerce software is an online sales platform with product, cart, payment and shipping processes coded to the business's needs, with no rent or commission. Hakan Sevimoğlu has built e-commerce platforms tailored to the paint and furniture industries, as well as order panels integrated with Aras Kargo.

Industry-specific product structure

Industry needs such as color charts and packaging options in paint, or bed base–headboard–mattress combinations in furniture, are hard to handle on off-the-shelf platforms. With custom e-commerce software, these structures are designed correctly from the start.

Product pages are built with structured data and speed optimization to rank at the top of Google.
