Professional User is a software service provider based in Costa Rica. Its Beriozka software is designed for sales and business management in physical retail locations. According to the website, the company has been developing point-of-sale solutions since 2005 and has served more than 200 customers across use cases such as supermarkets, restaurants, hardware stores, butcher shops, pharmacies, and liquor stores.
Based on the available page content, Beriozka’s core capabilities are centered on POS and store back-office operations: sales management, inventory management, electronic invoices or simplified invoices, and receiving/purchasing management. The website also lists entry points for an online invoicing system, accounting portal, XML queries, license registration, update downloads, and a technical support app, suggesting it is more of a localized store management solution than a general-purpose enterprise SaaS platform. Information about team collaboration, granular permissions, APIs, open platforms, and similar capabilities is not disclosed.
The official website does not publish plans, pricing, billing cycles, or feature tiers. It only states that users can contact the company for pricing and schedule a free, no-obligation product demo. In terms of service, the site mentions a professional technical support team that can handle questions or issues, and provides a support app download, but it does not disclose support hours, SLA details, or specific support channels.
Its strengths are its highly focused use case coverage, including checkout, inventory, electronic invoicing, receiving, and other high-frequency workflows for small and midsize physical stores. It also has a long operating history and an established local customer base. The drawbacks are limited transparency: security and compliance are only described in general terms as “security,” with no details on backups, permissions, audit logs, certifications, or similar safeguards. The deployment model is also unclear. Although there is an online invoicing system and a login panel, it is not possible to determine whether this is a fully cloud-based SaaS product.
This product is better suited to physical retail, restaurant, and small-merchant businesses in Costa Rica and Spanish-speaking markets, especially merchants that need local electronic invoicing workflows. Access from China is unknown, and there are major differences in language, tax rules, payment methods, and local invoicing systems, so its direct value for Chinese users is limited. If operating in China, it may be better to compare local alternatives such as 客如云, 哗啦啦, 有赞, and 微盟 first. For international POS needs, options such as Loyverse, Lightspeed, and Odoo POS may be worth considering.
