Learn more →System migration · How we work
Leaving desktop or legacy accounting doesn't have to mean starting from scratch or trusting a rough import. We move your chart of accounts, opening balances and full transaction history from systems like Sage into Zoho Books or Xero. Then we check the new ledger against the old one, year by year, before we call it done. You get a clean, budget-ready system, plus reporting you can rely on from day one.
Bookkeeping & accounting
Good decisions start with numbers you can trust. We keep your books up to date in Zoho Books or Xero, check every bank line rather than relying on automatic rules, and reconcile each account to the bank balance. Whether you run one company or several across different currencies and countries, you get accurate records and clear monthly reports, so you always know where your cash and profit stand.
Tax planning
No nasty surprises: we plan them out before they happen.
The biggest tax savings are decided before a sale, distribution or year-end, not after. We model the options in plain numbers. That covers when to sell, how gains and income flow through a trust, and who should carry them. We bring in your existing tax adviser to confirm, so decisions are based on clear workings, not guesswork.
Strategic finance / fractional CFO
We work alongside owners and boards as a fractional finance partner. We connect your long-term goals to the numbers that drive them: where cash really comes from, what the business can afford, and the steps that get you to where you want to be. We build clear forecasts and debt and funding plans, test the big decisions before you make them, and then track progress every month so the plan stays on course as things change.
Why us
We combine accounting, systems and strategy in one place, set up for multiple entities and currencies, and every number is checked back to its source.
Finertecture, by Thornbird. Not every business needs, or can afford, a full-time CFO. So we built Finertecture: the springbok’s leap, in your pocket. It brings Thornbird’s financial architecture to small businesses at a price they can afford, because every business that survives and grows creates jobs for South Africa’s youth.
