The Simplex Story
Simplex Business Support was founded by Luis Filipe to bring something different to small business accounting: fixed fees, genuine accessibility, and a personal service that actually feels personal.
After more than 12 years in the accounting industry, Luis saw the same problems over and over — hidden fees, faceless firms, accountants who treated small businesses as an afterthought. So he built Simplex to be the opposite.
Based in South East London and serving clients nationwide, Simplex operates on a WhatsApp-first model. Your accountant is just a message away — no tickets, no call centres, no waiting days for a response.
Every client gets one dedicated accountant who knows their business inside out. Fixed monthly fees mean no surprises. And because we genuinely care about the businesses we work with, we proactively advise — not just react.
That's accounting the way it should be.
