01
Catalog lags on thousands of products
Builders and ready platforms stall once items pass 5,000+: pages load slowly, filters hang, the customer leaves.

Custom online store with a large catalog and supplier sync
We build online stores on custom code for complex catalogs: tens of thousands of products, automatic supplier import and instant search. What site builders and SaaS platforms can't handle — with no turnover-based subscription and no structure limits.

§ 02 — Problem
Where off-the-shelf breaks
02
Stock and prices fall behind
Suppliers change availability and prices daily. Entering thousands of items by hand is impossible — you sell what is already out of stock.
Severity03
Subscription grows with turnover
SaaS platforms take a monthly fee or a percentage of sales. The more you earn, the more the store itself costs.
Severity04
Weak search — products go unfound
Without smart search and precise filters the buyer can't find the right model by size, color or season — and closes the tab.
Severity05
Thousands of cards without SEO text
There is no one to write unique descriptions for every product, so cards don't rank in search and bring no traffic.

§ 07 — FAQ
Common questions
Start — from $2500 for a store with a catalog, cart, checkout and basic integrations. The final price depends on the number of products, the number of suppliers to sync, and filter complexity.
Yes. We build the catalog on custom code with indexing and caching, so tens of thousands of items open and filter without lag — unlike ready-made site builders.
We set up automatic import of prices, stock and new items from supplier feeds on a schedule. In the Airstep case three sources are connected at once with automatic updates.
A store takes about 4–8 weeks. A complex catalog with several integrations and custom search takes longer. We fix the exact timeline after the technical brief.
Builders and SaaS limit the catalog structure, charge a subscription or a percentage of turnover and slow down at scale. Custom gives full control over search, filters, integrations and your own code.
