If you’re trying to grow a solo or small firm practice, you generally shouldn’t work for free unless you have a deliberate business development objective in mind. Conversely, if you have a client willing to pay, you generally should prefer to scale up your headcount instead of turning down work due to lack of bandwidth.
Does this mean you should never turn down a client who is willing and able to pay your fees?
No. There are lots of reasons it might make sense to turn down a paying client….
