Common Startup Problems

Becoming self-employed should be filled with excitement, and not a mad scramble for contract and invoice templates, or worrying about tax or how to look professional.

Scope of advice is unclear

Consultants give advice — but what exactly is covered? Without a clear contract, clients assume your engagement includes ongoing support, implementation, and unlimited revisions. Disputes over what was 'in scope' are constant.

30-day payment terms mean cash flow gaps

You invoiced £5,000 last month but it hasn't landed yet. Consultants typically work on 30-day payment terms, which means a permanent gap between delivering work and getting paid. It catches new consultants off guard.

Higher income = bigger tax surprise

Consulting rates are higher than many freelance disciplines — which means the tax bill is too. Without a running estimate, consultants are often shocked when their first Self Assessment lands. The higher rate threshold creeps up fast.
