Where do professional services belong on a SaaS P&L—COGS or OPEX? In episode #323, Ben clarifies how to code implementation, onboarding, custom integrations, and the tricky custom development work that sometimes blurs the line with R&D.

- Why It Matters (Finance & Investor Lens)

Gross Profit Integrity: Correct COGS ensures reliable margins by revenue stream (subscription, services, usage) that investors expect.
Credible SaaS metrics: Clean separation supports accurate CAC payback (GM-adjusted), Cost of ARR, and LTV:CAC.
Valuation: Transparent accounting and financial systems reduce diligence friction and improve confidence in revenue quality.
Operator Clarity: Treat Professional Services as a self-sustaining business unit with clear targets for utilization and margin.

- Quick Checklist

Distinct GLs for subscription, usage, services revenue
Fully burdened Services COGS (wages, taxes, benefits, travel, tools)
Separate custom dev tracking (R&D vs. billable services)
Clear DevOps/hosting in COGS for delivery costs
CS in COGS only if non-selling (no quota/commission)

- Quote from Ben

“Code services where the work and dollars actually live. If you blur R&D and Services, you’ll either hurt gross profit—or your OpEx profile. Either way, investors will notice.”
