Six Costly Start-Up Mistakes to Avoid in 2026

Starting a business in Australia has never been more exciting, or more challenging. With tighter economic conditions and rising costs, the margin for error in 2026 is slimmer than ever. At Honcho, we have helped more than 900,000 Australians start and manage their businesses, and we continue to see the same early mistakes derail otherwise promising ideas.

Recent research shows that around one in three new small businesses fail within their first year, and nearly half do not make it past four years. This insight, drawn from national studies and our own platform data, highlights why getting the fundamentals right from day one matters.

Below, we share the six most common start-up mistakes we see, and what you can do to avoid them.

Delaying registration

One of the biggest pitfalls is waiting too long to register your business. Spending months refining an idea often leads to lost momentum and missed opportunities.

"Get your business registered and operational quickly," says Miralda Ishkhanian, Chief Operating Officer of Honcho."Complete it in days, not months. It's not the key to business success, and you don't need to be an expert. Get it done and focus on growth."

Aiming for perfection

Many founders hold off launching because everything is not perfect. In reality, progress beats perfection.

“Starting a business is messy and iterative,” Ishkhanian explains. “A simple, functional website is better than no website. Refinement can happen as you grow.”

Overspending too early

Overspending in the first year can drain cash flow fast. Long-term leases and unnecessary overheads often put pressure on new businesses before revenue is stable.

“Many start-ups waste thousands locking into long-term leases when flexible options like virtual offices exist,” says Ishkhanian. “Focus on generating revenue.”

For example, a virtual office can cost around $100 per month compared with thousands for a physical workspace.

Neglecting a professional image

First impressions matter more than ever. A clear business name, professional email, logo and domain help build trust quickly.

“A polished business name, domain, logo and professional email build instant credibility,” Ishkhanian says. “In 2026, trust is currency.”

Budgeting too optimistically

Underestimating costs and overestimating sales is a common trap.

“Plan for your first year by halving your sales expectations and doubling your costs,” says Ishkhanian. “It keeps you prepared for cash flow shocks and unexpected expenses.”

Forgetting the human connection

Technology and AI can streamline operations, but relationships still matter.

“The practical rule for 2026 is simple,” Ishkhanian says. “Automate the routine, but don’t outsource the relationship. Keep trust-building moments human, especially when decisions are complex or high-stakes.”

Why this matters in 2026

With thinner margins and higher costs, these mistakes are more damaging than ever. Avoiding them can mean the difference between surviving your first year and closing your doors.
