Approach

  1. 01Challenge

    The brand sold through a standard online store and wanted to open new European markets without building a separate site for each country. It needed a system that could open a country in days, respect the strict rules for communicating about CBD products and show honestly where every order came from.

  2. 02Approach

    We built one core with a profile per market: language, currency, prices, couriers, payments, legal texts, SEO and tracking. Every risky feature sits behind its own switch, and every release goes through automated tests.

  3. 03Result

    Less than four weeks after the first line of code, all nine stores were live. Today the platform brings together the catalogue and local pricing, delivery through local carriers, card or cash-on-delivery payment, content in nine languages and a private centre for order and ad intelligence.

Highlights

  • 019 countries · 9 languages · 5 currencies, one core
  • 02Google Ads and Meta campaigns for every country
  • 0315 local carriers through one fulfilment partner
  • 04More than 3,000 automated tests

How it’s built

CH. 01—06

Chapters

Cannapopolis Core is a platform we built for the brand: it runs the brand’s CBD-oil stores in Bulgaria, Romania, Greece, Hungary, Italy, Slovenia, Czechia, Poland and the Netherlands. Each store has its own language, currency, couriers, payments, legal pages and SEO, and behind the storefront sit customer-journey tracking, a dossier for every order and a watch on the checkout.

CH. 01 / 06 — Multi-market platform

One core, nine countries

One codebase runs nine national stores. Each market has its own language, currency, prices, couriers, payments, legal pages and SEO: nine stores that work as one multilingual, multi-country shop.

CH. 02 / 06 — Tracking & attribution

Following the whole customer journey

From first touch to delivery, every step leaves a trace: only with consent, and with no names, emails or phone numbers in the reports. Without consent the source stays “unknown”; the system never guesses.

A click from search or an ad

Campaigns are reported per market and never mix countries or currencies.

CH. 03 / 06 — Ads & measurement

Campaigns for every country

We built separate Google Ads and Meta campaigns for every store and every country. The ads centre sets their reports next to the store’s real orders, and copy is checked against banned-claim lists because CBD is a restricted category.

Google Ads campaign

Separate Google Ads campaigns for every store and its country, each reported per market.

CH. 04 / 06 — Reliability

A checkout that never sleeps

A flight recorder follows every checkout step, from the cart to the confirmation, in all nine markets. Recording is pseudonymous and never stops a sale if the recording itself fails.

    error codes, each with a clear cause

  • 9

    markets under watch

Bulgarian checkout on a phone: Econt, Speedy, Pigeon, BOX NOW and cash on delivery, with the Profile / Cart / Quick order / AI bar
