We are Advanced Consulting Institute OÜ, a privately held company operating in the staffing and recruiting industry. We were founded in 2024 and are headquartered in Tallinn, Estonia.

We are not a traditional staffing agency or umbrella company; we position ourselves as an infrastructure partner that bridges the gap between flexibility and formalization. We enable modern workers to invoice clients, receive monthly salaries, and access social protections — all within a secure, scalable legal framework.

We deliver payroll, invoicing, and employer-of-record services that comply with local regulations across the European Union. Through our integrated ecosystem, we serve freelancers and consultants, gig workers and creators, domestic and cross-border clients, and agencies and partner platforms. Our services include monthly payroll with tax and insurance, RUT/ROT-adapted invoicing in Sweden, custom fee structures and optional pension packages, a legal entity and compliance backbone for mobile professionals, and platform integration and white-label solutions for scale.

Our specialties include engineering solutions, alcohol, business consulting, and facility management and cleaning.
