The client is a major international wholesaler operating on a cash-and-carry model, with a strong presence in Central Europe. Its customers are professional buyers – hotels, restaurants, caterers (the HoReCa segment), event venues, and independent merchants – who rely on the wholesaler for a broad range of food and non-food products at competitive, volume-based prices.

In this kind of business, the field sales representative is a key channel. Winning a hotel or a restaurant chain as a customer often depends on presenting a compelling, tailored offer during a face-to-face meeting. That, in turn, depends on the rep being able to assemble an accurate offer on the spot – pulling from the current assortment and, critically, the current prices, which change frequently and carry defined validity windows.

Pretius delivered an application built specifically around how the wholesaler's sales representatives work. The app lets a rep assemble customer-specific offers and orders, integrates with the company's data warehouse and existing product catalog, and synchronizes with the dynamically changing price list – taking each price's validity period into account so quotes stay accurate. Because the app had to perform in a live meeting as well as at a desk, a great deal of attention went into UI/UX and day-to-day usability on both tablet and desktop.

The project ran in an Agile (Scrum) methodology. A small, stable two-person Pretius team delivered the work over roughly a month and a half, with one developer from the client's side joining the team to collaborate directly.

It allows for leveraging existing investments in PL/SQL logic while opening the system to the modern web and cloud world. The client's case is proof that even the most complicated legacy systems can be modernized without operataThe wholesaler didn't need a heavyweight, months-long platform. It needed to put an accurate, easy-to-use offer configurator into its sales representatives' hands, usable on a tablet in front of a customer and always in sync with a fast-moving price list. By working in a tight Agile loop with the client's own developer and building on an Oracle APEX foundation, Pretius delivered exactly that in about six weeks – a mobile-first app that connects to live product data, respects price validity periods, and makes it easy to turn a client meeting into a tailored offer.ional paralysis of the company, as long as you choose your migration partner correctly.
