What Durable EBITDA Improvement Looks Like

The board asks for 400 basis points of earnings before interest, taxes, depreciation and amortization (EBITDA) improvement by Q3. The CFO builds a plan: reduce headcount in non-revenue functions by 12%, renegotiate vendor contracts, and consolidate infrastructure. The plan is implemented. Twelve months later, EBITDA is up 180 basis points. The question nobody asked: how much of the available margin was sitting in the commercial model, untouched?

The Revenue at Stake

EBITDA improvement plans that start with cost reduction are leaving the largest lever unexamined. For most B2B software companies operating between $20M and $150M annual recurring revenue (ARR), 60-70% of available EBITDA improvement sits in the commercial model, not in the cost structure.

The math is straightforward. A 3% improvement in price realization on a $50M ARR business adds $1.5M to EBITDA at near-100% margin. A 10% reduction in S&M spend on the same business saves $800K but typically compresses growth and offsets the savings with increased churn. One is a commercial problem. The other is an operational tradeoff that often destroys more value than it saves.

The reason commercial levers get deprioritized is that they require coordination across sales, marketing, finance, and product, and that coordination is harder than signing a vendor renegotiation. So businesses take the 180 basis points they can get through operational discipline and explain away the remaining 220 as "market conditions" or "competitive dynamics."

In PE-backed (private equity) software with a 3-5 year hold, the compounding effect of that missed EBITDA is significant. 220 basis points of missed margin for three years on a $50M ARR business at a 10x EBITDA multiple translates to $3.3M of unrealized exit value. That's not a rounding error.

The Working Model

Commercial EBITDA improvement operates through three distinct mechanisms.

Step 1: Map your price waterfall to find where margin is leaking. Your price waterfall starts at list price and ends at pocket price, with every discount, concession, free service, delayed payment, and off-invoice adjustment along the way. Most businesses know their nominal discount rate. Few have mapped the full waterfall, including free professional services, implementation credits, extended payment terms, and marketing development funds. The gap between list and pocket price is usually 8-15% higher than what the CRM discount field shows.

Step 2: Identify your highest-margin customer segments and protect them. Not all revenue contributes equally to EBITDA. Calculate contribution margin by customer segment, size, vertical, acquisition channel, contract term. In most B2B software businesses, 20-30% of customers generate 70-80% of the EBITDA, while the bottom quartile may actually destroy margin when fully loaded cost-to-serve is included. Protecting and expanding your high-margin segments is a faster path to EBITDA improvement than cost reduction in any functional area.

Step 3: Systematize renewal uplift as a margin mechanism. Annual price increases on existing customers are the most predictable EBITDA lever available to a SaaS business. A $40M ARR business with a 5% annual renewal uplift program across 70% of its base adds $1.4M in incremental ARR per year with no additional customer acquisition cost (CAC). Yet most B2B software companies have renewal uplifts of 0-3%, driven entirely by whatever the customer success (CS) team can negotiate account by account. Systematizing uplift, contractual escalators, value-based pricing reviews, CPI linkage, removes the negotiation entirely and makes the margin improvement automatic.

Where the Plan Breaks

A PE-backed SaaS business at $67M ARR had committed to a 500bps EBITDA improvement over 24 months as a condition of the capital raise. The initial improvement plan was headcount-focused: a 15% reduction in G&A, elimination of two product development workstreams, and renegotiation of four major vendor contracts.

By month 18, the plan had delivered 210bps of improvement. The headcount reductions had also compressed net revenue retention from 104% to 97% as CS capacity was reduced. The vendor renegotiations had yielded 60% of projected savings. The two eliminated product workstreams had resulted in three customer losses totaling $800K ARR.

The commercial model had not been touched. Average discount rate remained at 29%. Renewal uplift was averaging 1.8% across the base. The price waterfall had never been mapped.

Before: $67M ARR, 29% average discount, 1.8% renewal uplift, 14% EBITDA, 500bps improvement target.

After: After a commercial model redesign in month 20, which included pricing floors, a renewal uplift program contractualizing 4% annual escalators for new contracts, and a deal desk implementation, EBITDA reached 19.5% by month 30. The additional 550bps came entirely from commercial improvements with no further cost reduction.

The root cause was a margin improvement plan that started at the wrong end of the P&L.

Steps for This Quarter

Map your price waterfall this week. Start with your list price and calculate, for your last 12 months of closed deals, the sequential deductions: negotiated discount, free services, extended payment terms, any off-invoice credits. Get to pocket price.

If pocket price is more than 12% below list price and your nominal CRM discount shows less than that gap, you've found your EBITDA opportunity. It's not in the cost structure. It's in what you've been giving away.
