Stretching out appointments.
Whether employed, self employed or freelance this is particularly self sabotaging.
Prices should calculated based on business costs, stock used and worked out into time.
If the appointment should take 45 mins and stretched to 1 hour it could mean the difference of making a loss or even working below min wage.
If extra time is needed then you should confidently charge more!
Think about a visiting a bar or restaurant; a cocktail tends to be more expensive than other alcoholic drinks on the menu.
This isn’t necessarily because a cocktail is a bigger drink.
instead, it has more elements to it, which require more time to make and more skill from the bar staff.
You are therefore; charged more.
