Online store development
Online stores on Shopify, WooCommerce, OpenCart, Horoshop or Magento, or a custom store when the catalogue or the checkout does not fit a platform: a catalogue, a cart and a checkout connected to payments, delivery, receipts and your order system, for selling in Ukraine, in the EU or worldwide.
What we build into an online store
Catalogue and search
Categories, filters, variants and product pages imported from your spreadsheet or accounting system, with a search that finds products by name, by article number and by the words customers actually type.
Payments in Ukraine and abroad
Card payments through LiqPay, WayForPay or monobank, Apple Pay and Google Pay, and Stripe, PayPal or Shopify Payments when you sell outside Ukraine.
Delivery by Nova Poshta, Ukrposhta and Meest
Branch and parcel locker choice at checkout, the delivery cost, waybills created from the order and tracking sent to the customer, all through the carriers’ APIs.
Receipts and orders without retyping
Electronic receipts from a software cash register such as Checkbox, and orders passed to KeyCRM, SalesDrive, your accounting system or your ERP, so nobody copies an order by hand.
Marketplaces and product feeds
Product feeds for Prom.ua, Rozetka and Google Merchant Center, generated from the store’s own prices and stock.
Speed, search and analytics
Fast category and product pages, structured data for products and reviews, and Google Analytics 4 e-commerce events, so you see which products, campaigns and checkout steps bring sales.

Test orders through every payment and delivery option before launch
How we build an online store
We start from how you sell today: where the products and prices live, who processes an order and how it reaches the customer. The store is built around that process, so an order flows from the checkout to the payment, the receipt, the waybill and your accounting without being retyped.
Before launch we place test orders with every payment and delivery option and check the receipts and waybills they produce. The store, the payment accounts and the domain are registered to your business, and your team manages products, prices and orders in the admin panel without us.
Other kinds of website we build
Landing page development
Landing pages for launches, ad campaigns and events: one offer and one action, designed in Figma, built on Webflow, Framer or WordPress, with forms, analytics and ad tracking set up.
Business website development
Websites for small and medium-sized businesses, from a one-page business card site to a catalogue with booking: found in Google, editable by your own team, in Ukrainian and English.
Corporate website development
Corporate websites with many sections and languages, publishing by several teams, careers and news, CRM integrations, security and accessibility, on WordPress, Drupal or a headless CMS.
Website redesign
Website redesign: a review of the current site, a new design in Figma, the content moved and every old address redirected, on the same platform or a new one, with speed and search traffic measured before and after.
Website support and maintenance
Technical support for live websites: CMS and plugin updates, tested backups, uptime and security monitoring, fixes and content changes, and domain and certificate renewals, on a monthly plan with the hours on every report.
Websites for communities and public institutions
Official websites for communities and their councils, administrative service centres, schools, libraries and hospitals, with online services, a community app and chatbot and open data, accessible to DSTU EN 301 549 and WCAG 2.2, procured through Prozorro or a grant.
Websites for NGOs and charities
Websites for NGOs, charitable foundations and homeowners’ associations: card donations from Ukraine and from abroad, public reports, forms for volunteers and for people asking for help, and an English version for international donors.
Questions about online store development
How much does an online store cost?
It depends on the platform, the size of the catalogue, the design and the integrations with payments, delivery and your accounting. After a short brief you get a written estimate with the scope, the dates and the price, and the work starts only when you have agreed to it.
Which platform should our store be on?
Shopify when you want a hosted platform with little upkeep, especially for selling abroad; WooCommerce or OpenCart when you want the store on your own hosting with full control; Horoshop when you want a hosted Ukrainian platform; Magento or a custom store for large catalogues and complex pricing. If you already have a store, we work on its platform.
Can you connect our store to Nova Poshta, Checkbox and our CRM?
Yes. These services publish APIs, and the store calls them directly: branches and delivery costs from the carrier, receipts from the cash register, orders to your CRM. Where a ready module exists for your platform, we install and configure it; where none does, we write the integration.
How quickly can e-commerce developers start?
When the right e-commerce developer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.
How do we hire e-commerce developers through BigTree108?
Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.
Who owns the work they produce?
You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.
Starting or moving an online store?
Tell us what you sell, where you deliver and how you take payments. You get an answer within one business day: the platform, the integrations and an estimate.
