Best PSA Software for Small Business: 8 Picks

Website: https://www.scoro.com/

Best for: Full PSA for agencies and consultancies

Starting price: €15 per user/month

Free plan: Free trial (14 days)

Pros: One shared data model for sales, delivery, time, and billing; Pricing starts at 15 euros per user per month

Cons: Five user minimum on every combination; Full quote-to-cash combinations cost more than the entry figure

Scoro is a professional services automation platform that runs quoting, projects, time, billing, and reporting in one place. It is built from eight core apps that you mix and match, so you start with only the apps your workflow needs and add more as the firm grows. Time logged in one app flows into invoicing in another, and deals won in sales become projects in delivery without re-entry. That shared data model is the main reason small agencies pick Scoro over a set of separate point tools.

The vendor pricing page states that combinations start from 15 euros per user per month, with a five user minimum on every combination and an annual billing discount of 13 to 17 percent. A team of five therefore pays at least 75 euros per month at the entry combination, before add-ons. The ready-made combinations cover time billing, projects and resources, quote to cash, and end to end, and the full stack costs more than the headline figure. A free 14-day trial is available.

Best for: Agency budgets and resource planning

Starting price: $9 per user/month (billed annually)

Free plan: Free trial (14 days)

Pros: Budgeting, resource planning, and time tracking in the entry plan; Three seat minimum keeps the entry cost low for small teams

Cons: Invoicing relies on integrations rather than a native flow; Ultimate tier needs a sales conversation and has no public price

Productive is an agency management platform that holds projects, schedules, time, budgets, and invoices in one system. Its entry plan, Essential, includes budgeting, resource planning, project and task management, docs, time tracking, expense management, reporting, and time off, so a small firm gets the financial core without moving to a higher tier. That breadth at the entry price is unusual in this list, and it is why Productive suits agencies that want profit tracking from the start.

The vendor pricing page totals $90 a month for 10 users on Essential, which is $9 per user per month, with a three seat minimum on all plans. Professional totals $240 a month for 10 users, which is $24 per user per month, and adds rate cards, billable time approvals, recurring budgets, and advanced reports. Ultimate is quote only and adds revenue forecasting, multiple subsidiaries, and HubSpot integration. A free 14-day trial is available with no credit card required, and there is no permanent free plan.

Best for: Quote-to-cash for service firms

Starting price: quote only

Free plan: No

Pros: Sales, projects, retainers, tickets, time, and billing in one flow; AI features flag at-risk budgets and forecast capacity

Cons: No public prices, so budgeting needs a sales call; Onboarding is a separate line that is not published

Accelo is a professional services automation platform that connects the full client work cycle, from sales and quoting through projects, retainers, support tickets, time tracking, billing, and reporting. It is built for agencies, consultancies, accounting firms, engineering firms, and IT services firms that want one system for the whole engagement rather than a set of connected apps. The platform now includes AI features that forecast project risk and margin, a focus that grew after Accelo acquired Forecast in July 2025.

The Accelo pricing page shows no per-user figures and asks visitors to request a custom quote based on team size and growth goals. Older per-user figures still circulate on review sites, but Accelo does not confirm them on its own site, so a buyer should treat them as history rather than current prices. There is no free plan and no free trial listed, and onboarding is handled as a separate package with a fee that is not published. That makes Accelo hard to shortlist on cost alone, and it fits firms that are ready for a sales-led buying process.

Best for: Enterprise-grade PSA for larger service firms

Starting price: quote only

Free plan: No

Pros: Deep resource management with over 1,200 prebuilt connectors; Built for firms of 50 to 5,000 plus people

Cons: Built for larger firms, so a small team may find it heavy; Implementation often runs into months rather than weeks

Kantata is a professional services automation platform formed when Mavenlink and Kimble merged, and it combines project management, resource planning, time and expense tracking, and financial management for services firms. It is built on Salesforce in its cloud form and connects to accounting tools such as QuickBooks, NetSuite, Sage Intacct, and Xero, with more than 1,200 prebuilt connectors listed on its site. The vendor describes it as a fit for professional services organizations of 50 to 5,000 plus employees, which places it above the small business range for most buyers reading this list.

The Kantata pricing page carries no list prices and asks visitors to fill out a form so a PSA advisor can build a tailored plan based on company size, goals, and working style. No public figure exists, so a buyer should get the quote in writing. There is no free plan. A small firm can still ask for a quote, but the depth, the implementation time, and the enterprise focus mean Kantata is usually a better fit once a firm passes 50 people.

Website: https://www.bigtime.net/

Best for: Time, billing, and profitability for firms

Starting price: $20 per user/month

Free plan: Free trial

Pros: Essentials includes time, invoicing, expenses, and QuickBooks integration; Resource management and quotes are available as add-on modules

Cons: Resource management, quotes, and Data Hub are priced on request; Advanced reporting sits on higher tiers

BigTime is a professional services automation platform built around time tracking, project budgeting, invoicing, and profitability reporting for consultancies, accounting firms, and engineering firms. Its strength is the link between time entries and billing, so every hour connects to budgets, utilization, and the general ledger instead of sitting in a separate tracker. The platform also offers AI features, a mobile app for time and expenses, and integrations with QuickBooks, HubSpot, Salesforce, Jira, and Sage Intacct on higher tiers.

The vendor pricing page states that BigTime Essentials starts at $20 per user per month, with time tracking, invoicing, expense management, and payments included, plus the QuickBooks integration. Advanced is $35 per user per month and adds multi-currency expenses, custom reporting, and a client portal. Premier is $45 per user per month and adds resource allocation, multi-currency invoicing, and project budgeting. Projector is $60 per user per month for multi-entity teams. Resource Management, Quotes, and Data Hub are modules priced on request, and a free trial and demo are available.

Best for: Job management for small service firms

Starting price: $7.50 per user/month (billed annually)

Free plan: Free trial (14 days)

Pros: Every feature is on every plan, with cost set by team size; Native Xero sync for invoices, bills, and payments

Cons: Essentials needs 3 to 25 users, so a two person firm cannot start on it; Timesheet approvals and capacity planning need the Advanced plan

WorkflowMax is job management software for service firms, rebuilt in 2024 after Xero retired the original WorkflowMax, with quoting, jobs, timesheets, invoicing, and a native Xero sync. It covers leads, quotes with online acceptance, job phases, Kanban views, scheduling, capacity planning, purchase orders, and reporting, and every feature is available on every plan, so the plan choice is about team size rather than feature gates. That structure suits small firms that want the full tool without paying for a higher tier to open a single feature.

The vendor pricing page lists three per-user plans with monthly, quarterly, and annual billing, where quarterly billing saves 5 percent and annual billing saves 10 percent. In US dollars, Essentials is $8.33 per user per month billed monthly, or $7.50 billed annually, for 3 to 25 users. Pro is $15.00 billed monthly, or $13.50 annually, from 5 users, and Advanced is $25.00 billed monthly, or $22.50 annually, from 10 users. A 14-day free trial is available, and there is no permanent free plan.

Best for: Simple PSA for small to midsize teams

Starting price: $14 per user/month (billed annually)

Free plan: Free trial (30 days)

Pros: Covers clients, projects, budgets, time, expenses, and invoices in one place; Team costs $14 per user per month billed annually

Cons: No permanent free plan, so every user needs a subscription after the trial; Advanced features sit on the Pro plan at $30 per user per month

Ruddr describes itself as the simplest and most cost-effective professional services automation product, built for professional services organizations from 10 to 10,000 personnel, with support for over 150 currencies. It captures clients, projects, budgets, tasks, resource allocations, time, expenses, utilization, invoices, and revenue in one system, so a small team can run delivery and billing without adding a separate finance tool. The interface is deliberately light, and the vendor positions it for small to midsize teams rather than enterprise firms.

The vendor pricing page lists the Team plan at $14 per user per month billed annually, or $17 billed monthly, and the Pro plan at $24 billed annually, or $30 billed monthly. A 30-day free trial is available, and there is no permanent free plan. Confirm the figures on the vendor pricing page before signing.

Best for: AI resource planning inside Accelo

Starting price: quote only

Free plan: No

Pros: AI scheduling, auto-scheduling, and project portfolio views; Now part of Accelo, with shared data across sales and delivery

Cons: Standalone pricing is gone, so you must go through Accelo sales; Small teams that only need scheduling may find the full platform too large

Forecast is an AI-native project and resource management platform that organizes team schedules into visual plans, maps upcoming projects, and uses auto-scheduling to place work against capacity. It covers project portfolio management, resource allocation, financial tracking, and time. Accelo acquired Forecast in July 2025, and the combined product pushes predictive scheduling, cost and margin insight, and automated workflows from sales through billing.

The Forecast pricing page now redirects to the Accelo pricing page, which shows no per-user figures and asks visitors to request a custom quote based on team size and growth goals. That means Forecast can no longer be bought or priced as a standalone tool, and a small firm that wants it must go through the Accelo sales process. There is no free plan and no free trial listed on the pricing page. Forecast still makes sense as a shortlist item for firms that already plan to buy Accelo, but not as a standalone scheduling purchase.
