Revenue is recognized the moment a service happens: the cleaning, the adjustment, the forty-five-minute session. Cash arrives much later, sometimes six to eight weeks later, after a claim has been submitted, reviewed, adjusted, and finally paid. A practice can be fully booked and still be waiting on money for services delivered a month or two ago.
