Move furniture before lease start date?

Hello good people, long time listener/reader first time poster. My wife and I have recently purchased our first small Multifamily and have signed a lease with our first tenant. The lease is signed and first and security is in our possession, however the lease doesn’t officially start until Aug 1. The tenant has asked if she can have furniture delivered before Aug 1.
How should we go about this? Any advice is appreciated. Thanks!
