Multi-supplier marketplace for Serbia
A Serbian marketplace uniting 15 local suppliers in one shop. Customers order, pay, and get support in one place while suppliers fulfill directly.
About
appy.rs was launched in October 2026 by Pascual Solutions, a small development company from Pirot, Serbia. The idea was to offer Serbian shoppers a broad assortment at fair prices without the shop holding stock itself: every supplier keeps its own warehouse and the shop sells its goods under one brand, one checkout and one customer service.
The Serbian market sets clear requirements. Most customers pay cash on delivery, every sale must be fiscalised with the tax authority, parcels go by local courier services, and prices, texts and communication are in Serbian dinars and Serbian. Many suppliers have no proper data feed. Some send XML, some an Excel stock list by e-mail, some have only an online shop, and a few have nothing at all.
Before choosing Aimeos we built a prototype on a Node.js stack, but taxes, stock handling and order processing would all have had to be written from scratch, and the memory each process needed even without traffic was a problem for a company that wants to host many small shops. Aimeos already covered most of what we needed and left the rest open for extension.
The web application
The platform is split into two parts. The backend is Aimeos on Laravel: admin panel, JSON:API, background jobs and e-mails. The storefront is a separate Next.js application that uses the Aimeos JSON:API plus a few endpoints of our own. All shop logic lives in our own Laravel packages, so the Aimeos core stays untouched and can be updated.
The heart of the platform is the supplier synchronisation. Each of the fifteen suppliers has its own reader: XML and CSV feeds, Excel lists fetched from a mailbox, WooCommerce and GraphQL APIs, and a browser-based reader for a B2B shop without a feed. A feed is read in full before anything is written, deletions above 30 % are held back for review, and no product is created until its category, brand and options are mapped in the admin panel. Selling prices are calculated from the effective purchase price with a margin that falls as the price rises, and never above the supplier's own retail price. Suppliers without any IT get a simple mobile panel where they set the stock of their products themselves.
Around the catalogue we integrated the local services a Serbian shop depends on: fiscal receipts issued automatically through an approved online cash register, the X Express courier with supplier confirmation, shipping labels and status webhooks, cash on delivery, and bank transfer with the National Bank's IPS QR code. We extended the admin panel with our own tools: rule-based dynamic categories, automatic product ranking, order editing, CMS blocks for the storefront, and product feeds for price-comparison portals and advertising platforms.
The whole platform is covered by more than 680 automated tests.
Results
appy.rs went live on 1 October 2026 with more than 16,000 products in 459 categories and 290 brands, all kept in sync with the suppliers without manual work. Real orders started on the first days after launch, and every order flows automatically from checkout through supplier confirmation and courier dispatch to the fiscal receipt.
In load tests with a generated catalogue of 50,000 products, filtered category pages and full-text search stayed below half a second at the 95th percentile on a single server, which gives the shop plenty of room to grow. Because the platform is built as one installation per shop, the same code can serve other merchants. We are already preparing it for our next e-commerce projects.
