Does a Consulting Firm Need NetSuite or Sage Intacct?

Not always, and not as early as software vendors will tell you. A consulting firm with a handful of consultants and straightforward monthly retainers can often run well on QuickBooks with a time-tracking tool bolted on. The real trigger isn't headcount, it's whether you can answer three questions quickly: what's our utilization by consultant this month, what's our realized margin by engagement, and what's our pipeline of committed future revenue. If those take days to assemble instead of minutes, that's the actual signal, not an arbitrary revenue threshold.

Watch for these signs that a consulting firm has outgrown QuickBooks:

• Producing utilization by consultant or realized margin by engagement takes real staff time every month instead of a few clicks.
• Work in progress lives in a spreadsheet that gets less reliable as the firm grows.
• Multiple practice groups need margin sliced by practice, consultant, and client at the same time.
• Partner compensation, with different origination and delivery credit, is calculated in a shadow spreadsheet each quarter.

A firm running one practice area can usually get away with simple project tags. Once you're running multiple practice groups, strategy, operations, M&A support, each with its own partners, margin profile, and utilization targets, you need dimensional reporting that can slice by practice, by consultant, and by client all at once without a custom report built from scratch every time someone asks. That's the point where Sage Intacct's dimensional structure starts to earn its cost, letting you tag every transaction with practice group, consultant, and client simultaneously.

Work in progress, hours delivered but not yet billed, is the number that quietly erodes cash flow in a consulting firm if nobody's watching it. A spreadsheet-based WIP tracker works fine at a small scale and becomes unreliable exactly when you need it most, when you're running many concurrent engagements and a partner needs to know which ones are running over budget before the client does. Both NetSuite and Sage Intacct can track WIP by engagement automatically, tying it directly to your billing and revenue recognition rather than living in a separate file someone updates by hand.

Realization, the percentage of a consultant's billable time that actually gets invoiced at the intended rate, is a related but different number worth tracking alongside WIP. A firm can look fully utilized on paper while realization quietly slips because of scope creep or informal rate discounts nobody documented, and a system that reports the two side by side makes that gap visible before it shows up as a cash problem.

For most consulting firms below roughly a hundred consultants and running out of a single country, Sage Intacct's project accounting and dimensional reporting cover the ground without the heavier implementation NetSuite requires. NetSuite becomes the better fit once you're operating across multiple countries or legal entities and need consolidated financials in real time rather than a manual roll-up at month-end. Payables days are also worth checking directly against your own numbers rather than assuming a single average applies across all consulting subtypes¹.

If you're a single practice area, a handful of consultants, and your billing is simple retainers or straightforward hourly work, QuickBooks paired with a dedicated project-costing tool can carry a firm further than most partners expect. The honest test is whether finance is spending real hours each month reconstructing utilization and margin by hand. Once that becomes a recurring drag on the team rather than an occasional annoyance, it's worth pricing out Sage Intacct properly instead of adding another workaround spreadsheet on top of QuickBooks.

Once a firm has multiple partners with different origination credit, delivery credit, and profit-sharing arrangements, the accounting system needs to support that compensation structure without a separate shadow spreadsheet running the actual math every quarter. This is less about the ERP itself and more about whether your chart of accounts and dimensional tags capture origination and delivery separately at the point an engagement is billed, so the partner compensation calculation can pull straight from the ledger instead of being reconstructed from memory and old invoices. Neither platform solves this automatically; it has to be designed into how you tag revenue from day one.

Get this structure right before you migrate, because untangling a year of blended origination and delivery credit after the fact is far more painful than setting the tags up correctly the first time.

If you're staffing up your own internal finance or accounting function as the firm grows, benchmark what those hires actually cost before building a budget around a guess. The national median wage for accountants and auditors is $83,680 a year, which tends to run above what many founders initially budget for a first controller-level hire². Build that into your hiring plan rather than discovering the gap mid-search.
