Accounting firms are a relatively stable business file

Accounting practices can merge, relocate, change ownership, or close, but they generally turn over more slowly than high-churn categories such as restaurants. Our US business data is refreshed quarterly, Canada data is refreshed annually, and we estimate roughly 90% accuracy on business records. For large purchases, ask when the specific file was last refreshed.
