Accounting Hacks and Mishaps Costing You Money
TLDR: Accounting may seem boring, until it slows your growth, kills your investment and costs you £££. Join our session and learn the hacks and pitfalls that can save, or lose, your startup money.
What to expect
Accounting might not be the first thing you think about when building a startup - but the truth is, hidden finance mistakes can cost you funding rounds, create painful legal cleanups, or even put your business at risk.
Join us for a practical deep dive session with Ruben Portz (COO, Novabook) and Tom Kelly (Chartered Accountant & Chief of Staff, Novabook). Ruben and Tom will walk you through the most common financial pitfalls founders make — and the simple systems, hacks, and best practices to avoid them.
With experience supporting 500+ startups (from incorporation through to scale and exit), they’ll share real-world insights and tactics that founders can implement immediately, including:
The filings and compliance steps founders miss (and why investors care).
Bookkeeping hacks that save hours and prevent costly mistakes.
VAT and payroll choices that can save thousands if you get them right.
Smart structures for handling cash, expenses, and R&D credits.
Underrated tax-efficient hacks founders overlook.
📌 Whether you’re pre-seed, scaling fast, or gearing up to fundraise — this session is packed with practical insights founders can apply straight away.
