Best PSA Software for Mid-Size Firms Compared

Website: https://www.accelo.com

Best for: Client work, retainers, and billing in one place

Starting price: quote only

Free plan: No

Pros: Client work, projects, and billing in one system; strong retainer and recurring revenue tracking

Cons: Quote-only pricing slows budgeting; the interface takes time to learn for new staff

Accelo brings sales, projects, time, and billing into one record for each client, which suits firms that run retainers alongside fixed-fee work. Managers can see time against budgets, track recurring revenue, and follow a client from quote to invoice without moving between systems. The platform also links with QuickBooks and Xero, so finance keeps one ledger while delivery teams work in Accelo.

For a mid-size firm, the value sits in the retainer tools and the utilization views that show billable time by person and team. Setup takes planning, because the system covers a wide range of workflows and each one needs rules for rates, approvals, and billing. Firms that run mostly project work may find parts of the sales side unnecessary, so a demo with real client scenarios is the right way to judge fit.

Website: https://www.kantata.com

Best for: Large project portfolios with resource forecasting

Starting price: quote only

Free plan: No

Pros: Portfolio views across many projects; resource forecasting tied to project plans

Cons: Quote-only pricing hides the entry cost; setup can take months for a large team

Kantata, formerly Mavenlink, is built for firms that manage a portfolio of projects rather than a handful of jobs. It combines project planning, resource management, time tracking, and financial reporting, with forecasting that shows demand against capacity weeks ahead. Integrations with Salesforce, Slack, and Jira help it sit beside tools a firm already runs.

A firm of 50 to 200 people can use Kantata to plan staffing across teams and to spot bottlenecks before they hit delivery dates. The trade-off is depth against speed: the platform rewards firms that invest in setup and training, and smaller teams may find the range of features more than they need. Ask for a written quote that covers the modules your teams will actually use.

Website: https://www.scoro.com

Best for: Quoting through invoicing on one record

Starting price: €15 per user/month

Free plan: Free trial (14 days)

Pros: Quotes, projects, time, and invoices share one record; modular combinations let you buy only the apps you need

Cons: Five-user minimum on every combination; the full suite costs far more than the entry combination

Scoro is a modular platform made of eight core apps that cover quoting, projects, time, resourcing, and invoicing. Firms pick combinations of apps, and the lowest combination, Time-billing, starts at €15 per user per month, with a five-user minimum. The Projects and Resources combination adds the scheduling and delivery views a mid-size firm usually needs, at a higher rate that depends on the apps selected.

The single-record design means a quote, the project plan, the time logged, and the invoice all draw on the same data, which cuts rework between sales and finance. Dashboards show utilization, project profit, and pipeline value in one place. Watch the modular pricing: the entry figure buys a narrow set of apps, so price the combination that covers your full workflow, not the headline rate.

Best for: Time tracking tied to billing and QuickBooks

Starting price: $20 per user/month (billed annually)

Free plan: Free trial (14 days)

Pros: Time, expenses, and invoicing connect directly; deep QuickBooks integration with two-way sync

Cons: Resource management sits in higher tiers; higher tiers need a sales quote

BigTime starts at $20 per user per month on the Essentials plan, which covers time tracking, basic invoicing, expense management, and the QuickBooks link. Higher tiers add client portals, custom reporting, resource allocation, and multi-currency invoicing, with Advanced at $35, Premier at $45, and Projector at $60 per user per month. Utilization and margin reports show which staff are billable, which projects run over budget, and where profit leaks.

For firms that bill by the hour, the link between time entries and invoices is the core strength, and the QuickBooks sync keeps the books current without double entry. The catch is the tier ladder: real resource planning only arrives at Premier, so a mid-size firm should budget for that tier rather than the entry price. A trial helps confirm whether the reports match how your firm measures utilization.

Best for: Accounting-led firms that bill by the hour

Starting price: quote only

Free plan: No

Pros: Accounting, time, and billing share one ledger; strong project accounting for hourly firms

Cons: Quote-only pricing with no public list price; setup can be heavy for teams without accounting staff

BQE CORE is built for architecture, engineering, accounting, and consulting firms that treat project accounting as the center of the business. Time, expenses, billing, and the general ledger sit in one system, so invoices draw straight from logged hours and project costs. The platform tracks budgets, work in progress, and realization rates, which are the numbers partners in a mid-size firm watch most closely.

The accounting depth is also the main risk: firms without accounting staff may find setup slow, and the interface favors finance workflows over simple task tracking. BQE does not publish a list price, so every buyer needs a quote, and the final figure depends on modules and user count. Firms that already run QuickBooks should check how the two systems share data before committing.

Website: https://www.usehalo.com

Best for: Service desks that want deep customization

Starting price: £66 per agent/month (billed annually)

Free plan: Free trial (30 days)

Pros: One per-agent price covers every module; deep workflow customization with no feature tiers

Cons: An onboarding package is required at extra cost; there is no built-in RMM, so a separate tool is needed

HaloPSA publishes one price per agent, with every module included and no tiers to compare. On the UK pricing page the rate is £66 per agent per month billed annually. The platform covers ticketing, projects, billing, and asset management, with more than 250 integrations listed by the vendor.

For a mid-size service team, the appeal is the flat structure: every agent gets the same features, so there is no mid-contract upgrade needed for reporting or automation. The cost to watch is onboarding, which Halo requires with every purchase and prices by scope, plus the need for a separate RMM tool, since HaloPSA does not include one. The 30-day trial covers the full platform and needs no credit card.

Best for: MSPs that pair PSA with a separate RMM

Starting price: quote only

Free plan: No

Pros: Deep ticketing, agreements, and billing for MSPs; wide integration range across the ConnectWise suite

Cons: Quote-only pricing with no public list; setup is complex and takes weeks for a mid-size team

ConnectWise PSA, formerly ConnectWise Manage, is the long-established PSA for managed service providers. It covers service tickets, agreements, projects, time, procurement, and billing, with workflows built around service level agreements and recurring contracts. It pairs with ConnectWise RMM and other tools in the same suite, and it links with QuickBooks for accounting.

A mid-size MSP gets a platform that handles the full service lifecycle, from ticket intake to invoice, with reporting on agreement profitability and technician utilization. The cost is complexity: configuration takes time, training matters, and pricing is quote only, so two firms of the same size can receive very different figures. Get the quote in writing with the modules named, and plan a phased rollout rather than a single cutover.

Website: https://www.autotask.com

Best for: MSPs that want tickets, projects, and billing together

Starting price: quote only

Free plan: No

Pros: Tickets, projects, contracts, and billing in one system; close fit with Datto RMM

Cons: Quote-only pricing with no public list; the interface has a learning curve for new staff

Autotask PSA, part of Kaseya, covers service desk tickets, projects, contracts, time, and billing for IT service firms. It is built to work beside Datto RMM, so tickets from monitored devices can flow straight into the service queue. Dashboards track technician utilization, contract profitability, and project progress, which are the core numbers for a mid-size MSP.

The platform suits firms that want one system for service delivery and billing, rather than stitching several tools together. The drawbacks are familiar for this category: pricing is quote only, the interface takes time to learn, and buyers should confirm what the Kaseya bundle includes before signing. A demo with your own ticket and contract data gives the clearest view of fit.

Website: https://www.teamwork.com

Best for: Client-facing teams that need a low entry price

Starting price: $9.99 per user/month (billed annually)

Free plan: Yes

Pros: Lowest entry price in this list; free plan covers up to 5 users and 5 projects

Cons: Basics lacks timesheets and capacity planning; the top tiers are quote only

Teamwork publishes clear prices for its first two tiers: Basics at $9.99 per user per month billed annually, with a three-user minimum, and Accelerate at $24.99, with a five-user minimum. Basics covers project delivery, client organization, and billable time tracking, but it stops before timesheets, workload capacity, and invoicing. There is also a free plan for up to 5 users and 5 projects, and the subscription tiers carry a 14-day trial.

For a mid-size firm, Teamwork works best when the priority is client project delivery with clear budgets and time tracking, rather than deep resource forecasting. The features a 100-person firm usually needs, such as workload planning and capacity views, sit in Accelerate and above, and the top tiers are quote only. Price the tier that holds the features you need, and check the 300-project cap on Basics before you commit.

Website: https://www.monograph.com

Best for: Architecture and design firms tracking project profit

Starting price: quote only

Free plan: No

Pros: Built for architecture and design workflows; project profit and phase budgets are easy to follow

Cons: Quote-only pricing with no per-user list price; narrow focus suits design firms more than general consultancies

Monograph is a PSA platform built for architecture and design practices, and its pricing page works as a calculator rather than a list price, so buyers get a quote based on team size and needs. The platform tracks project phases, budgets, time, and fees in views that match how design firms run work, with reports on project profit by phase and by person.

For a mid-size design firm, that focus is the main attraction: the workflow, the language, and the reports all match practice life, and the QuickBooks link keeps billing in step. For a general consultancy, the same focus can be a limit, since features for other service types are thinner. Ask for a written quote early, and check that the phase and fee structures match how your firm prices work.
