Alexander Sullwald — DirectorSuldax exists for businesses that need more than a bookkeeper but aren't ready for a big-four retainer. Led by director Alexander Sullwald, we bring seasoned expertise to startups and SMEs — without the overhead.
Registered tax practitioner. SARS and SARB compliance built into every engagement — not bolted on afterwards.
Turnkey, tech-driven solutions — from systems integrations to IoT applications — that scale as you do.
One relationship covering strategy, finance, tax and systems — so nothing falls between the cracks.
A free consultation to unpack where your business is, where it's going, and what's actually in the way.
Registrations, compliance, accounting, systems and controls — foundations put right, so you're built to scale.
Ongoing advisory, reporting and cash flow management that keep you compliant, informed and moving forward.
Most SMEs can't afford a full-time CFO. Soon they won't need one. RocketCFO watches your cash, your deadlines and your numbers around the clock — and tells you what matters before it becomes a problem.
Built by Suldax, on the same controls-and-compliance discipline we bring to every client engagement.
A free, no-obligation conversation about your business — what's working, what's at risk, and what Suldax can take off your plate.
We'll be in touch when RocketCFO is ready for lift-off.
