There are a few reasons a job may not get accepted right away.
The job is slightly out of our service area. If this is the case, there are fewer Pros that will travel to you and it may take a bit longer for your job to get accepted.
More details are needed or the job may be out of scope for most Pros.
We simply do not have any Pros available within your requested time frame.
In each situation, customer support will reach out if we are unable to accommodate your request completely, need more info, or need a couple of backup dates/times to get the job accepted.
