For a services firm, choose the point where commercial control must become reliable. Kantata is worth shortlisting for connected forecasting, resourcing and financial oversight; Scoro for a configurable combination of operational apps; Productive for budgets and resource planning with explicit higher-tier financial controls; Accelo for a tailored client-to-profit operating workflow; and BigTime when the required billing and cost controls define the edition. A task list or timesheet is only part of that purchase. The useful PSA is the smallest configuration that keeps sold scope, planned capacity, incurred cost and the invoice consistent.
What the buying decision includes
Apply the same questions to each platform: who approves the estimate, when tentative demand becomes committed capacity, how employee cost rates enter margin, who can change recorded time and which record reaches accounting. Fixed-fee projects, time-and-materials work and recurring retainers need different controls. Compare those controls for the same mix of work rather than treating a vendor’s lowest per-user number as a complete PSA configuration.
| Platform | Useful starting point | Package boundary | Buying question |
|---|---|---|---|
| Kantata | Connected resource, delivery and financial oversight | Custom pricing by firm and operating requirements | Which deployment, finance workflows and connectors are contracted |
| Scoro | Build the required quote-to-cash app combination | Eight core apps; five-user minimum; separate extras | Which roles need Estimate, Resource, Spend and Invoice |
| Productive | Resource planning connected to project budgets | Professional adds approvals; Ultimate deeper financial oversight | Whether forecasting, subsidiaries and overhead require Ultimate |
| Accelo | Client operations connected to delivery and margins | Tailored quote includes platform and onboarding guidance | Which workflow, integrations and implementation tasks are covered |
| BigTime | Billing-led control of services delivery | Premier adds cost/rate management and multi-currency invoicing | Whether core PSA or Enterprise and added modules are needed |
Kantata
Kantata connects project and pipeline information with resource planning and financial oversight. Its current platform description places forecasting, delivery, resourcing and financials together. This is relevant when staffing decisions need to reflect commercial commitments, not just the next task assignment. Ask which source owns tentative demand and what happens to the forecast when a deal moves or a project’s scope changes. Kantata official source.
Pricing is tailored to company size, goals and the way the team works; the page does not establish a universal per-seat tariff. Obtain the chosen product/deployment, required integrations, reporting scope and implementation effort in the proposal. A published connector count cannot establish that a specific accounting workflow is supported or included. Shortlist Kantata when connected planning and oversight justify a scoped implementation, while keeping any advertised margin or utilization improvement out of the business case until it is relevant to your own operations. Kantata official source.
Scoro
Scoro’s current offer is modular: Do, Deliver, Track, Resource, Sell, Estimate, Spend and Invoice can be combined by role. That changes the evaluation. A time-billing combination is not equivalent to an end-to-end setup with sales, estimating, delivery and financial operations. Map the estimate-to-invoice handoff to the actual apps and identify who needs access to each. Scoro official source.
The page lists a five-user minimum, monthly and annual terms, eight core apps, platform choices and additional extras/integrations. Standard and Enterprise also differ in controls such as SSO and provisioning. Request a role-by-app configuration and onboarding quote, including the required financial and accounting extras. Choose Scoro when you want to assemble a connected operational system; a small subset can make sense, but its starting price should not stand in for the cost of your full workflow. Scoro official source.
Productive
Productive’s Essential plan lists budgeting, resource planning, project management, time, expenses and reporting. Professional adds recurring budgets, rate cards, billable-time and expense approvals, and HRIS/invoicing integrations. Those distinctions matter if a manager must approve work before it affects client billing. Compare the required approval path with the plan, rather than counting the presence of a budgeting screen. Productive official source.
Ultimate adds items including revenue forecasting, multiple subsidiaries, overhead calculation and stronger access enforcement. The captured pricing page exposes conflicting figures and totals across its dynamic monthly/yearly display, so this comparison does not quote a per-user amount. Confirm the billing term, seat requirement and configured total in the live offer. Productive is a useful shortlist for connected delivery and commercial visibility, provided the forecast and financial-control tier matches your requirements. Productive official source.
Accelo
Accelo’s current buying page connects client and pipeline data, delivery visibility, capacity and project financials. It is relevant when client work should move through one operating record instead of being reconstructed from CRM notes, project tools and billing exports. Its offer includes access to the full platform with implementation guidance and onboarding support, according to the pricing FAQ. Accelo official source.
The proposal is based on team size and growth goals, not a published universal tier price. Specify the project and retainer mix, source of rates, accounting handoff, migration history and the staff responsible for maintaining the system. Full-platform access does not settle how much configuration or integration work is included. Choose Accelo when the proposed operating workflow fits the firm; do not revive older modular prices or treat the vendor’s revenue-leakage claims as your expected result. Accelo official source.
BigTime
BigTime Essentials covers time and expenses, portfolio management, billing and invoicing, reconciliation and a QuickBooks integration. Advanced adds capabilities including multi-currency expenses and custom reporting. Premier adds multi-currency invoicing, cost/rate management, project budgeting and multi-level approvals. The financially relevant edition can therefore be higher than the plan that merely records hours and sends an invoice. BigTime official source.
BigTime also separates its core PSA from an Enterprise route for greater organizational complexity, and presents additional modules for the broader client journey. Ask whether scoping, resource planning and the required finance model belong to the base subscription, an added module or Enterprise. The entry-price headline does not state every commercial term needed for an equivalent proposal, so obtain currency, commitment, user minimum and implementation scope together. Features marked coming soon are not included in this recommendation as available capabilities. BigTime official source.
Which purchase fits your operation?
Normalize the commercial control before the seat price. Shortlist Kantata for connected planning and financial oversight, Scoro for role-based app configuration, Productive for project budgets with tiered financial controls, Accelo for a tailored client operating workflow, and BigTime for an edition chosen around billing, rates and approvals. The lowest tier that tracks time may still be the wrong tier for protecting project margin.
A firm with reliable accounting and a simple scheduling gap may only need resource planning. A firm that repeatedly sells work without knowing delivery cost needs a clearer commercial model as well as software. Agree on the authoritative estimate, cost rate, approved timesheet and invoice record before migration. Retain a distinct accounting responsibility: a PSA profitability view should not be assumed to replace every ledger or revenue-recognition requirement.
For related decisions, compare resource planning for future team capacity and time tracking for the record of billable work.
