Take a well-loved shop online without adding work
Royal Tea & Coffee sells close to 200 teas, coffees, sweets and pieces of teaware from its shop in Iași, with prices and stock kept in the company's Sedona ERP.
Selling online meant pricing every product by weight and pack, accepting Romanian card payments, issuing invoices that satisfy ANAF, and keeping the website in step with the ERP without retyping anything.
One platform for both sides of the counter
We built a bilingual storefront that works as well on a phone as on a desktop, and a back-office where staff edit every page, run promotions and newsletters, answer support tickets and export invoices.
DDNET owned the whole engagement: product design, engineering, integrations, hosting and day-to-day operations. The project ran within the company's EU-funded digital transformation programme under Regio Nord-Est 2021–2027.
Engineered for every step of the purchase

Filters that answer instantly
Category, collection, rating, review and price filters narrow almost 200 products at once. The interface responds in under 50 ms while the server confirms, and a smart sort puts the products the team wants to feature first.
Every variant priced and in stock
Each tea or coffee comes in several weights, grinds and packs, each with its own price. Shoppers see the VAT-inclusive price for the exact option they pick, whether it is in stock, and can ask to be told when it is back.
A cart that protects the margin
The cart shows the VAT breakdown, counts down to free shipping, takes vouchers and gift cards and offers gift wrapping. The server re-prices every line, so a tampered price is blocked and logged before it reaches checkout.
Checkout built for Romania
Guest or account checkout, for private customers or for companies with their fiscal code and trade register number. Payment by card online through ING WebPay or in cash on delivery, with every payment event written to a log nobody can edit.
A private assistant that only quotes real data
Signed-in customers ask for recommendations or the status of an order. The model runs on DDNET's own GPU and answers only through six read-only tools over the catalogue, the customer's orders, FAQ, blog and promotions. Product names become links generated by the server, and conversations are deleted after 30 days.

A back-office the team runs themselves
Everything lives in one admin, with roles that decide who can change what.
ERP import
Imports the Sedona ERP's exports by category. New products arrive unpublished for review, and copy the team wrote is never overwritten.
Price watch
Flags prices that stand out within their product group before they go live, so a typo can't sell a kilo of tea for the price of 50 g.
e-Invoicing
Produces invoices as UBL 2.1 XML in the CIUS-RO format of ANAF's e-Factura, numbered from a gapless yearly series.
Promotions
Percentage, fixed and free-shipping vouchers, timed campaigns, usage limits and gift cards.
Newsletter
Double opt-in subscriptions and scheduled campaigns, sent from a background queue so the shop never slows down.
AI product imagery
Generates images, retouches photos or places a pack into a new scene, with approval before anything is used.
Support and reviews
Support tickets, review moderation and a complete order history with an audit trail.
Pages and content
Pages assembled from 51 content blocks, with every interface label editable in both languages.
The client restyles the shop without a developer
An admin opens a panel on the live site and picks a seed colour. The platform generates a full light and dark palette in OKLCH and checks six text pairings against WCAG AA. Two font slots, menus and body text, choose from six families. Changes preview instantly and publish to every visitor in one click, with no rebuild.

The storefront in the screenshots above runs a custom indigo theme the client published this way. Try the options on the right: the colours are the generator's real output.
