A start date that slips by a week rarely shows up as a line item, so it usually gets treated as a minor scheduling issue. It is not. Every day between an accepted offer and a first shift carries real cost in lost output, redistributed workload, and recruiter time spent managing the wait. Most of those days trace back to one place: how long it takes to clear a candidate for work.
The Costs You Can Actually Count
Start with the role itself. An unfilled position still has work attached to it, and that work goes to overtime, agency cover, or the rest of the team. Add the recruiter hours spent chasing paperwork, the hiring manager check-ins, and the cost of running the process a second time if the candidate walks away. Then add the on-ramp period, because a hire who begins two weeks late is also productive two weeks later.
For high-turnover roles, those numbers repeat across every hire. In home care, industry estimates put the cost of losing a caregiver at $2,600 to $5,000 per departure in recruiting and retraining alone (ShiftCare). Every day a clearance sits in a queue is a day closer to losing that candidate to an agency that moved faster. That is why turnaround time in employee screening carries more financial weight than it usually gets credit for.
Where the Delay Usually Starts
Delays are rarely caused by a single test. They build up when requirements are scheduled separately, results come back on different timelines, and no one owns the full picture. A candidate books a drug test one week and a physical the next, then waits on a result that sits with a third vendor. Nothing has technically gone wrong, but ten days have passed and the start date has already moved. The pattern is easy to miss because each step looks reasonable on its own.
Turnaround Time Is the Lever
Consolidating requirements with one provider compresses that timeline, because scheduling, results, and documentation move together instead of arriving piecemeal. Mobile Health returns comprehensive pre-employment screening results in an average of 1.9 business days,* which is the difference between a recruiter guessing the start date versus committing to one. Grouping drug and alcohol testing, physical exams, and any required vaccines or titers into a single visit removes most of the dead time between steps, and it gives HR one place to check status rather than three.
Match the Setting to the Hiring Volume
For steady, individual hiring, clinic-based testing is usually the fastest route because candidates can be seen close to home and booked as soon as the next day. Mobile Health has 6,500+ clinic locations nationwide, with 77% of employees living within 10 miles of one. For hiring cohorts, seasonal ramps, or multi-site rollouts, on-site employee screening clears large groups in a single visit instead of spreading them across weeks of individual appointments. Both settings work well. The avoidable cost comes from using the wrong one, such as booking forty seasonal hires into individual clinic visits during a two-week hiring window.
Standardize Requirements by Role
A number of delays come from uncertainty about what a given role actually needs. When requirements are decided case by case, someone has to confirm the panel before anything can be booked, and that confirmation often takes longer than the test itself. Mapping each role to a fixed set of requirements ahead of time means the order can be placed the same day an offer is accepted, and it keeps the process consistent across locations and managers.
Make Delays Visible Before They Cost You
Most start date slips are predictable a few days out, if anyone is watching. Centralized status tracking lets HR see which candidates are cleared, which are pending, and which have not booked at all. The Client Portal keeps clearances and results in one place across locations and roles, so a stalled file gets chased on day two rather than surfacing on day ten, when the start date is already gone.
