What is Deal Size?
The average revenue value of closed sales deals, typically measured as Average Contract Value (ACV) or average deal size, reflecting the typical customer's initial purchase.
Understanding the Details
Deal size is a key lever in the revenue equation: Revenue = Deals × Deal Size × Win Rate. Increasing average deal size directly impacts revenue without requiring more pipeline. Deal size varies by segment (enterprise deals are larger than SMB), by product (multi-product deals are larger), and by sales process (well-run discovery expands scope). Strategies for growing deal size include multi-year commitments (often with discounts), multi-product bundles, implementation services, and premium tier positioning. However, pushing deal sizes too aggressively can lengthen sales cycles and reduce win rates. The goal is finding the optimal deal size that maximises total revenue, not just individual deal value.
How It Works in Practice
Deal size growth
Introducing a professional services package increases average deal size from £15K to £22K ACV, with no decrease in win rate.
Segment analysis
Average deal size for mid-market is £25K versus £8K for SMB, informing the decision to invest more in mid-market sales capacity.
Multi-year incentive
Offering a 15% discount for annual commitment increases average deal size by 85% (monthly to annual) while improving retention.
Why It Matters
Deal size directly impacts revenue efficiency. A 30% increase in average deal size has the same revenue impact as a 30% increase in deal volume — often with less effort.
What People Often Get Wrong
Bigger deals are always better. Actually, larger deals often come with longer sales cycles and lower win rates — the net impact depends on the math.
Deal size is fixed by pricing. Actually, deal size is influenced by discovery quality, packaging, negotiation, and the scope of problems addressed.
You should optimise for deal size alone. Actually, it's one variable in the revenue equation that must be balanced with volume, win rate, and cycle time.
