Good question! Initially, consider that the yearly salary of a senior web designer has now surged over $100,000, not including benefits (and it’s quite a challenge to find one who’s available). Furthermore, there might not always be sufficient work to fully occupy them, leaving you in a position where you’re paying for unutilized time.
With the monthly plan, you can pause and resume your subscription as often as you need to ensure you’re only paying your designer when you have work available for them.
