Fontis

Fontis is an eCommerce engineering consultancy built for complexity.

We specialise in designing, integrating, and optimising commerce systems where reliability, performance, and operational efficiency matter more than surface-level polish. When retailers outgrow simple platforms or find their stack held together by workarounds, Fontis steps in to make everything work cleanly, securely, and at scale.

Our team of senior eCommerce engineers works across the entire commerce stack: storefronts, middleware, ERPs, WMS, POS, PIMs, CDPs, and custom integrations. We’re known for backend-first thinking, composable architecture, and solving the kinds of integration and performance problems other agencies avoid.

Fontis is vendor-agnostic by design. We don’t take commissions, push preferred platforms, or sell unnecessary rebuilds. Every recommendation is based on what best supports your business today and where it needs to go next. That means clearer decisions, fewer re-platform regrets, and systems that scale without accruing crippling technical debt.

Clients engage Fontis when they need senior expertise without hiring a full in-house team. We bring experienced engineers and architects into critical moments: complex migrations, performance issues, integration failures, or strategic re-architecture, and leave behind systems your internal teams can confidently run and extend.

We work best with mid-market and enterprise retailers operating multi-site, multi-region, or omnichannel businesses, often with legacy systems or rapidly evolving tech stacks. Our role is to simplify complexity, eliminate inefficiencies, and build dependable commerce foundations that drive real commercial outcomes.

We focus on clarity, stability, and results. Quietly confident, deeply technical, and trusted by teams who need things to work properly now and long-term.
