You provide the client.
We provide the capacity.

Good Audit Seniors are hard to find.
There is another way to build capacity.
Common capacity pressures include:
- Growing audit portfolios
- Recruitment challenges
- Busy-season pressure
- Partner and manager overload
- Difficulty finding experienced Audit Seniors
- Difficulty finding ACCA-qualified accountants
