* On day 46 you pay your supplier for the stock - cash out.
* On day 101 you sell the stock.
* On day 217 you get paid for by your customer - cash in.
Between day 46 and 217 your money can be sitting with your supplier and your customer.
During that time your business will need to fund that difference and still provide funds for you to live on, or finance capital debt.
Although this looks like it applies to stock-holding businesses, the effect can be the same in a business that sells services.
So if the bank account is at zero, where can money come from to plug the gap?
Here are some of my picks:
Shortening credit terms to your customers and ensuring efficient collection methods.
Systemise and make clear credit terms and policies. Why not get paid up front for a discount?
Extending credit with suppliers might also be worth a shot. If you provide them a lot of business and are growing, they might be interested.
Bank overdraft - banks will want security and projections, depending on the security you could be paying up to 15 per cent on this facility.
Debt factoring is a way to get up to 90 per cent of your invoices paid up front. The factoring company will keep a commission so do your numbers to work out how this might affect profit.
If your businesses has a services or labour component, finishing and billing jobs is as important as an efficient stock monitoring process in a shop.
