My answer to What services are small businesses looking for in the finance/accounting field?
Answer by Ken Larson:
Most of my commercial clients perform their own general ledger accounting and hand an electronic file to an accounting firm at year end for tax preparation services.
A unique field in high demand is that of government contract job cost accounting. This is a specialty field under federal contracting regulations that involves compliance with Cost Accounting Standards (CAS).
Accounting firms that become expert in this field have tremendous services opportunities to small firms that enter government contracting.
