Context
Why generic accounting software breaks down for professional services
A consultancy running 500 projects across 5 entities needs fundamentally different accounting infrastructure than a single-entity business. Generic tools treat companies as sales + expenses. Professional services requires project profitability, WIP, utilisation, and resource allocation to be visible in real time — not reconstructed from spreadsheets.
Project margins are invisible in QuickBooks/Xero. These platforms group revenue by client or invoice date, not by project. A £500k project that should cost £200k but actually cost £350k appears profitable until someone manually extracts time sheets, billable hours, expenses, and costs. By then, it is too late to course-correct. Best accounting software for professional services firms must surface project economics in real time.
WIP and revenue recognition become manual. When billing is T&M or milestone-based, WIP tracking requires running cost and revenue balances at the project level every month. QuickBooks cannot do this. Finance teams run SQL queries or Excel formulas to calculate WIP, reconcile against the GL, and post revenue manually. That workflow is error-prone and defeats the point of accounting software.
Multi-entity consolidation is a nightmare. Firms with multiple subsidiaries using separate QuickBooks instances face month-end closes that take 10–15 days because consolidation is entirely manual. Sage Intacct and NetSuite automate this; the difference in close speed and error rate is dramatic.

FAQ
Frequently asked questions
Is Sage Intacct or NetSuite better for professional services?
For most mid-market professional services firms, Sage Intacct is the better fit — excellent project accounting, multi-entity consolidation, and flexibility to integrate existing PSA tools without the broader ERP footprint. NetSuite + SuiteProjects suits larger, global firms that want a unified ERP + PSA stack.
Can Sage Intacct handle project profitability reporting?
Yes. Sage Intacct’s project accounting engine ties time, expenses, costs, and revenue at the project level directly to GL. Project margins, actual vs budgeted costs, and WIP are calculated in real time — no manual spreadsheets required.
What’s the typical implementation timeline?
Sage Intacct: 3–6 months for most professional services firms. NetSuite + SuiteProjects: 6–12 months depending on subsidiary count and PSA scope. Timeline varies with size and existing system complexity.
Do we still need a dedicated PSA tool if we use Sage Intacct?
Many firms pair Sage Intacct with a dedicated PSA for deeper resource planning and project management, then integrate time/expenses back into Intacct for accounting. Others use Intacct’s project module standalone if PSA needs are light. Design flexibility allows both approaches.
