NetSuite vs Sage Intacct for M&A Advisory Success Fees

Start an engagement, log hours against it, and the deal moves through stages: initial mandate, marketing, diligence, negotiation, close. A retainer might bill monthly throughout. The success fee itself typically can't be recognized as revenue until the deal actually closes and payment is reasonably assured, since it's contingent on an outcome outside the firm's control.

That means the same engagement carries two different accounting treatments simultaneously: ratable retainer revenue recognized as earned, and a large contingent fee sitting entirely outside recognized revenue until close. A system that can hold both views for the same deal without manual workarounds is doing real work here.

Say a firm spent four months and several hundred hours on a mandate that fell apart in diligence: those hours were real cost, staff time, travel, data room access, but they generated zero recognized revenue. Job costing needs to capture that cost against the deal regardless of outcome, both to understand true engagement economics across the whole book and because partners evaluating deal-team performance need the full picture, not just the fees that landed.

NetSuite's project costing tracks this cleanly at the deal level, tying every hour and expense to a specific engagement whether or not it ultimately bills. Sage Intacct can do the same through dimensional tagging, though the discipline to tag time against dead deals consistently, rather than letting it disappear into overhead, has to come from the team, not the software.

Partners generally want to see every active mandate, its stage, its estimated fee, and a rough probability of close, updated in something close to real time. That's closer to a CRM function than a general ledger function, and neither NetSuite nor Sage Intacct is primarily a deal pipeline tool.

The practical answer is usually a connected CRM or deal-tracking tool feeding stage and probability data into the ERP, so partners get their pipeline view from the tool built for it while finance gets clean revenue recognition data flowing from the same underlying deal records without duplicate entry.

For any deal with a meaningful contingent fee, document the specific event that triggers recognition, deal closing and funds transferring, and keep that documentation consistent across every engagement rather than deciding case by case. This matters most at year-end, when an auditor will want to see why deals recognized in one period rather than another.

Both platforms can store engagement-level notes and attachments that support this, but the underlying policy, exactly when a success fee counts as reasonably assured, needs to be written down and applied consistently by your finance team before either system can enforce it.

Pull your last five closed deals and one dead deal, and ask each vendor to model the full lifecycle: retainer billing through the engagement, cost tracking regardless of outcome, and success fee recognition triggered at close. Frank, MeetMyCFO's AI CFO, can help you assemble that six-deal test set before the vendor call so you're testing against real engagement economics, not a hypothetical.

Gross margin on contingent-fee work looks very different from a pure hourly consulting model once you account for dead-deal cost, so benchmark your true margin, fees earned against total hours across both live and dead deals, rather than only the hours on deals that closed¹.

Give each vendor this test set to model:

1. Pull the last five closed deals and one dead deal from your records.
2. Have the vendor bill the retainer through each engagement's life.
3. Track cost against every deal, whether or not it closed, including the dead one.
4. Trigger recognition of the success fee at close, not on an estimated calendar date.
5. Ask to see the pipeline view partners want, and note whether it comes from the system or from a separate CRM.

Diligence work often runs up real out-of-pocket costs, data room subscriptions, travel, third-party advisors brought in for specialized diligence, and those need to track against the specific deal for reimbursement or cost analysis. Payables days on these deal-related vendors matter more than they might seem, since a firm juggling several live mandates at once can see vendor bills pile up quickly if approval routing isn't tight².

Confirm how each platform tags a reimbursable expense back to the deal it belongs to, since a diligence-heavy quarter with multiple live mandates makes manual expense allocation error-prone fast.
