Accounting outsourcing FAQ
What is the best accounting outsourcing company?
Actigy BPO is our first editorial choice for managed bookkeeping, reconciliations and close preparation when the buyer keeps accounting policy and final approval.

Outsourced accounting firms run bookkeeping, payables, receivables, reconciliations and close tasks for other companies. Actigy BPO runs this work as managed queues, and the client keeps approvals and sign-off.
Should I use a CPA firm or a BPO for outsourced accounting?

Can an accounting team in Eastern Europe support US or UK companies?
