Commit as little as possible to suppliers, frankness and loyalty to your suppliers will pay off. Keep orders small and leases short. It is easier to turn cash into more products than it is to turn excess products into cash.
It is better to bring employees in on contract first, try them out for 6 to 12 months and make sure that the business is sustainable before bringing then in full time. No one will blame you for failing to renew a contract but a layoff is a big, black mark.
