I'm closing on a $4M service company in Phoenix (asset purchase).

I'm mirroring the sellers legal structure which consists of 3 different LLCs all with their own set of books. The company uses Quickbooks Enterprise because it allows for job cost accounting. All employees are employed by one of the LLCs and employee sharing is accounted for with inter-company transaction entries. Other than that accounting is pretty straightforward.

I'd like to hire a CPA firm to handle the QB transition and payroll setup (the company does its own payroll with QB Enterprise) just so I don't over stress the accounting team with this as it's likely outside their skillset.

Any recommendations on who to use or how to go about sourcing the right firm that is familiar with this specific post-acquisition process? I feel like a lot of firms will tell me they can do it...but I really want to make sure I hire someone that is familiar with asset sale transitions specifically.

Thanks
