Good question! First, the average salary of a full-time senior Laravel developer is $115,000, plus benefits (not to mention the costs of finding and recruiting one). Aside from that, you may not always have enough work to keep them busy at all times, so you're stuck paying for time you aren't able to utilize. With the subscription you can pause and resume it as often as you need to ensure you're only paying your developer when you have work available for them.
