- Your purchased bucket hours remain valid for 6 months, during this time frame, you can utilize our services until your hours are exhausted or until the 6-month period expires.
- For example, if you invest in 40 bucket hours and use 10 hours within the first month, you will have a remaining 30 hours to utilize over the next 5 months.
- In this case, the developer will work for other projects simultaneously as you have opted for bucket hours and not dedicated hiring.
It's a convenient and efficient way to manage your developer needs on your schedule.

In dedicated hiring, the number of hours are not fixed like the bucket hours but instead, you are reserving the developer exclusively for your project.
- The developer will work only on your project for a set amount of time.
- You can choose to hire the developer for a week or a month, depending on what your project needs.
- This means our developer will focus exclusively on meeting the needs of your project, without any distractions from other commitments.
