Founded in 2002, Pentamid Ltd develops custom Windows software for businesses with specific needs that off-the-shelf solutions can't meet.

Susie Black, who founded the company, has over 30 years' experience in software development — including early work on pen computing and video conferencing long before they became mainstream. That same thoughtful, practical approach guides our work today.

We work closely with our clients to understand what they actually need, then build software that does exactly that.

Our focus is on bespoke Windows business software — though we occasionally work on web applications too. From initial design through to long-term support, we're there when you need us.

Over the years, we've tackled some interesting challenges. We've built software to monitor sewage flow (lovingly codenamed 'Sludgeview'), manage horse racing studs, handle currency exchange for ferry companies, and support temp recruitment agencies. We've even updated legacy regulatory software for the fragrance and flavouring industry — bit of a trial as you can imagine, but someone had to do it.

More recently, we launched PackTotal — our first ready-to-use product. It's designed to help UK businesses manage packaging data for EPR reporting and the Plastic Packaging Tax. Built on years of experience in regulatory software, it runs on your own server, so you can produce all the required figures without sharing sensitive business data. As far as we know, nothing quite like it existed before.

We work with businesses of all sizes, sometimes directly and sometimes collaborating with partners on projects. The common thread is usually that they need something specific that simply isn't available off the shelf. We're good at taking complex problems and finding practical, straightforward solutions.

If you're looking for custom software that actually fits how your business works, we'd be happy to have a chat about what you need. No obligation — just a conversation about whether we might be able to help.
