Margins

Outsource some in house tasks. So you've employed someone and they've only got about 10 hours work a week, either out-source it or get someone else to do that job as well.

Pay cash rather than loan interest. If you don't have enough to pay cash, then you probably don't need it. Or, just focus on paying as little interest as you can.

No discounting. It will kill you. No profit, no business. Sell less at a higher margin.  Profit is always better than turnover.

Measure everything. Know whether what you're doing is worthwhile and only stick with what works.

Only allow your team to buy with an authorised purchase order. If they haven't got an authorisation, then they can't make a purchase.

Lower your money tied up in inventory. Less stock means a far greater return on investment.

Create a brand new product or service. Perhaps a book, e-book, audiotape, or member-only website. This could generate a higher margin product for you to sell.
