# GorillaWorks > GorillaWorks builds back office software for staffing agencies. Its flagship platform, FlexBackOffice, automates contractor onboarding, timesheet collection, payroll processing, client invoicing, commission tracking, and margin reporting for staffing and temp agencies across the US and Canada. The platform processes over $3 billion in client invoicing annually and is ISO 27001 certified. GorillaWorks sits between an agency's ATS (Bullhorn, JobDiva, Loxo, Crelate, Vincere, Avionte, PCRecruiter) and its financial system (NetSuite, QuickBooks Online, Xero, Sage, Microsoft Dynamics), automating everything in between. It supports both contingent workforce placements and fully integrated Statement of Work (SOW) engagements, and pays W-2, 1099, T4, and incorporated workers. ## Solutions - [Staffing Agency Software](https://gorillaworks.io/staffing-agency-software): The all-in-one back office platform covering onboarding, timesheets, payroll, billing, and commissions in one system. - [Staffing Agency Billing Software](https://gorillaworks.io/staffing-agency-billing-software): Automated client invoicing.
