One useful thing a fortnight

A short email for small-business owners: one practical way to save time or win more work, with the numbers behind it. No fluff, unsubscribe anytime.

Why we built these

Most small-business advice online is either vague or trying to sell you something before it answers your question. These tools do the opposite: they answer one specific question each, immediately, and they're free to use as often as you like.

Every calculation is shown on the page, so you can check the maths yourself rather than trusting a black box. Nothing you type is stored — the numbers stay in your browser unless you ask us to email your results.

More tools coming

Break-even calculator, quote follow-up planner, job profitability tracker and invoice payment-terms calculator are next. Subscribe above and we'll tell you when they land.
