There’s a massive difference between profit and cash flow. Profit increases when you create an invoice for work you’ve done or goods you’ve sold; cash increases when you bank the money.
Your lockup equals the cash that isn’t in your bank account because it’s either in work in progress (you’ve done some work but you haven’t yet billed for it) or you have billed your customer but are waiting to be paid.
There are two key processes that need to be improved to reduce the cash that’s stuck in your lockup. Within each of these two processes, there are countless strategies that can be put in place to put more cash in your bank account.

The earlier you invoice a customer, the faster you’ll get paid. How quickly after delivery of a product or service do you bill? Do you carry significant work in progress because your service spans several weeks or even months? If so, should you consider progress billing on a regular basis?
