Thoughts on Service Costs

[JessPoynter]

Have y'all seen the new service cost tracker option? 
When working with hair, product costs vary for each person at each appointment (am I right?), so NATURALLY I was ecstatic to see this update: I appreciate having all my numbers in one place.

After switching the toggle (love that!), I was a little bummed to only see fixed and percentage as the options for adding in costs. I'm not sure about all of you other 'craft-based' business owners, but I don't have the same cost for each guest due to the fact, again, it changes every time based on need. 

What suggestions / workarounds have my other service providers and 'craft-based' businesses figured out? 

@lenjobakes @Doran @TCSlaguna how would you/do you all incorporate this?

I haven't taken a look yet, but our service providers are contractors who earn a percentage, which we have programed under commission in Appointments.

I just set mine up.  For the most part, my facials have the same cost breakdown so this may be helpful for me to track.
