Getting Started Is Simple
Initial Consultation
We learn about your business, its structure, and what you need. For new setups, we assess the optimal company form and tax registration strategy. For existing businesses, we review your current position.
Tailored Proposal
We prepare a clear scope and fixed-fee proposal covering exactly which services you need — no surprises, no hidden costs. You choose what to outsource to us and what to keep in-house.
Onboarding & Setup
We handle the paperwork — company registration, tax enrollment, payroll setup, bank coordination. For existing businesses, we manage the transition from your previous advisor seamlessly.
Ongoing Partnership
Monthly accounting, quarterly filings, annual accounts, and a dedicated contact who knows your business. We proactively flag risks and opportunities — not just process paperwork.
