Turning a strong local manufacturer into a global eCommerce brand requires more than a pretty storefront. It takes a repeatable product experience, reliable logistics, conversion-focused design, and the right integrations. In this case study-style overview we explain how we helped two Lviv-based manufacturers — Lviv Socks Factory and Grono Corporate — expand their digital presence and reach international buyers.
Custom software is often framed as an expensive, risky choice compared to off-the-shelf tools. The right way to evaluate it is not by sticker price, but by real ROI: the measurable value your business gains over time. In this article we explain the components of ROI for custom development, walk through a simple calculation, and share practical tips to maximize returns while managing risk.
Reducing development costs is a common goal for startups and SMBs — but cutting corners rarely leads to long-term savings. At 5Hz, we favour smarter trade-offs over shortcuts: pragmatic approaches that lower initial spend while protecting product quality, performance, and future scalability. Below are proven strategies our engineering teams use to deliver cost-efficient, high-quality software.
