Professional services software is sold on the promise of showing you which clients are profitable. What the pricing pages rarely show is the seat minimums, and the implementation fees that on some platforms cost more than the first year of licences.
Monthly cost on annual billing at three team sizes. Where a vendor does not publish rates, we say so rather than guessing.

Modern PSA built for agencies and studios that bill by the hour. Cleanest entry price in the category, and the only one here that does not charge an implementation fee.
$135/month for a 15-person team.
Watch out: The $9 Essential tier does not include resource scheduling or profitability reporting, which is why most agencies buy PSA software in the first place. The realistic entry point is Professional at $28.
Visit site →Time and billing first, project management second. Popular with accounting, engineering and consulting firms that care most about getting hours onto an invoice.
$285/month for a 15-person team.
Watch out: BigTime is built around time and billing. Firms expecting full project management with dependencies and Gantt views often find it thinner than a general PM tool at the same price.
Visit site →All-in-one system for consultancies, agencies and architecture firms. Combines sales, projects and finance in one place, with a five-seat minimum that catches small firms out.
$298/month for a 15-person team.
Watch out: Every paid plan requires a minimum of 5 seats. A three-person consultancy pays for five, so the real Core floor is roughly $100 a month rather than $60.
Visit site →In this category the licence fee is often the smaller number. Implementation runs from nothing on the modern tools to more than $25,000 on the enterprise platforms, and it is almost never shown on a pricing page. Ask what onboarding costs, how long it takes, and whether it is optional, before comparing per-seat rates.
Each tool has a detailed pricing page, and our PSA pricing guide covers the whole category.
