Operating vs Polaris (Deltek): Which PSA Fits Your Firm?
TL;DR
Choose Operating if you run a 15–250 person firm that needs fast adoption, better resource planning, and AI-native workflows. Choose Polaris if you are an enterprise-scale organization (250+ people) requiring deep financial governance, complex revenue recognition, and audit-grade project accounting. Operating ships in days, while Polaris requires long implementation project.
The data on PSA procurement and adoption
Software procurement for professional services usually fails on adoption, not a lack of features. Data suggests that while Polaris provides enterprise-grade control, it carries a high overbuy risk for smaller firms and a significant implementation burden. Operating is optimized for time-to-value, with a setup claim of less than 24 hours and transparent pricing starting at $12 per person/month.
The impact of visibility is concrete: firms using Operating for staffing and utilization, such as Inventive.io, have reported reducing unbilled work from $250,000 to $25,000. For firms prioritizing extensibility, Operating provides a production-ready Model Context Protocol (MCP) server, while Polaris’s AI features are currently focused on "ZeroTime" capture and embedded staffing suggestions.
Choosing by your operating model
The decision rests on whether your binding constraint is financial rigor or operational speed.
When to choose Polaris (The System of Record)
Polaris is the safer choice for CFO-led organizations that need a heavyweight PSA. It wins on revenue recognition policies, advanced billing structures, and WIP (work in progress) visibility. If your firm has 250+ people and financial control is a board-level concern, the configuration debt of a larger system like Polaris is often a necessary tradeoff for the auditability it provides.
When to move to Operating (The Operations Layer)
Operating is designed for firms that want one "command center" to manage the staffing-to-invoice loop without enterprise bloat. It excels at "pipeline-to-capacity" planning by pulling HubSpot or Pipedrive deals in as tentative projects natively. For European firms, Operating offers a localized advantage with EU AWS hosting in Frankfurt and native country-specific holiday calendars.

Frequently asked questions
Does Operating support multi-region teams and EU data residency?
Yes. Operating offers EU (Frankfurt) AWS hosting and native multi-region support, including distributed staffing and country-specific holiday calendars — useful for firms with European delivery teams, even as Operating's go-to-market leans US.
Which tool is better for a HubSpot-centric firm?
Operating. It is in the HubSpot marketplace and maps pipeline data directly to delivery capacity. Polaris connects to CRMs through integrations rather than a native handoff.
Can AI manage my weekly staffing meetings?
Operating's MCP server (early access) lets you use Claude or ChatGPT to ask who is free in March and write those allocations back to the plan. Polaris offers ZeroTime, SmartMatch, and its Dela assistant, but we found no public evidence of agentic write-back via an MCP server.
What is the minimum size for these tools?
Below ~15 people still running on founder memory, both are usually overkill; a lighter planning layer tends to serve better at that scale.
