Accounting for Siren’s Professional Services Enterprises

Certified India-based team with CPA oversight. WIP reporting, utilization metrics, and project profitability made simple.

Service firms in Siren depend on accurate time-tracking, clean billing cycles, and reliable monthly reporting. Our professional services accounting model helps Siren agencies, consultancies, legal firms, engineering teams, and advisors organize their financials so every hour and engagement is reflected correctly in revenue.
We refresh your Siren accounting workflow by structuring billable vs. non-billable categories, integrating time-tracking or CRM tools, aligning project/retainer billing, and organizing reimbursable expenses. This improves margin accuracy, clarifies utilization rates, and creates a smoother monthly close for your Siren leadership team.
