Sound familiar?

The catalog takes 5-8 seconds to load — half the shoppers leave before it opens

Stock on the site doesn't match the warehouse: customers order items that are gone

Checkout takes 6 screens — carts get abandoned halfway, especially on mobile

Sales depend on marketplaces and their fees, while your own store brings nothing

A store is a sales channel, not a storefront with a cart

The difference between a store that sells and a storefront that merely exists lives in the buyer’s path. Catalog speed. Honest stock. Checkout without a six-screen questionnaire. Payments that don’t fail. Every crack in that path is an abandoned cart. We design the store from the buyer’s journey, from the search query to the order-delivered email. And from ERP sync, without which any storefront starts lying.

The catalog: fast, filterable, demand-driven

The catalog passes two exams at once. The buyer’s exam: instant loading, attribute filters, live search with suggestions, no stock surprises. And the search engine’s exam. Categories and useful filter combinations become landing pages for queries like “affordable corner sofas”. Junk combinations get blocked from indexing. That’s the faceted-navigation work where stores either lose or build their organic traffic. Product pages carry full specs and markup. Price and rating show right in the search snippet.

A two-screen checkout and payments people trust

We compress checkout to two screens: cart with delivery, then payment. Address suggestions, saved details, guest checkout without registration. We connect the payment methods your buyers expect: cards, instant transfers, installments. Automated fiscal receipts where required. Every removed step cuts abandoned carts. Especially on phones, where more than half of orders now happen.

ERP sync: the storefront never lies

Stock, prices and orders sync with your ERP both ways. Sold offline — the item leaves the storefront. Repriced — it updates automatically. Orders land in the ERP without manual transfer, statuses and tracking numbers return to the buyer on their own. Cancellations over “turns out it’s out of stock” are the number-one killer of repeat purchases. Here they disappear by architecture.

Launch and growth

We launch in 6-10 weeks: catalog, checkout, payments, ERP integration, shipping. The store then grows on two levers. The first is SEO. In our profile case the store’s organic traffic grew 2.8x in 8 months and became the primary channel. The second is feature growth: loyalty, customer accounts, marketplace integrations. The foundation for all of it is laid at the start, so growth never hits a rebuild wall.

Client reviews

Client reviews

The catalog finally opens instantly, and stock matches the ERP. The is-it-in-stock calls have nearly disappeared. They used to be half of what our managers did.
Sergey L.Online furniture store owner
We migrated off the old platform fearing a rankings drop. The redirects and structure were done properly. No dip, and a quarter later organic traffic grew.
Olga T.Head of e-commerce
Checkout went from six screens to two. Abandoned carts fell noticeably, especially on phones. The return on investment was quick to count.

FAQ

FAQ about web development

01What do you build online stores on?

Whatever fits the task. From ready platforms to custom builds on Next.js and Node.js for stores with non-standard logic and high speed requirements. At the briefing we'll say honestly what's optimal for your catalog and budget. Sometimes custom isn't needed.

02Will you migrate products from the old site or from Excel?

Yes, migration is part of the project. We move the catalog, descriptions, photos and order history. We set up 301 redirects from the old URLs so rankings don't get lost.

03How much does an online store cost?

A base store with payments and ERP integration starts at $5,000. The price grows with catalog size, the number of integrations and custom logic: configurators, B2B price lists, multi-warehouse. The quote is free after a briefing.

04What happens to the store after launch?

We don't walk away. A 6-month warranty on the build, support and growth on an hour package. Most clients grow the store in iterations. Features get added from analytics data, not from hunches.

05Can you migrate off the old platform without losing rankings?

Yes, SEO migration is a practiced process. A redirect map from the old URLs, preserved metas and structure, indexing control after the move. In our SEO case the store survived the migration without a dip, and a quarter later organic traffic grew.
