Cash is the lifeblood of any business. Even profitable businesses can and do fail because of poor cash flow.
What’s important is that you understand your key cash flow drivers. Improving cash flow is often all about changing your processes. Processes such as how you order stock and pay for it, how you bill for your services, and how you make sure you get paid by your customers.

By lockup, we mean the cash that isn’t in your bank account because it’s a work in progress (work you have done but not yet billed for) or you’ve billed your customer but are waiting for payment.
For example, if your loans are being repaid over too short a term, this will place a big strain on cash reserves.
