Measuring outbound ROI for consulting firms

Stop tracking opens. Start tracking SQOs.

A Sales Qualified Opportunity (SQO) is a meeting with an in-ICP account where a buying authority is present, a trigger event has been confirmed and a next step is agreed. Booked meetings inflate. SQOs do not. The single most important number for a consulting outbound program is SQOs per dedicated SDR seat per month. Anything below 4 is underperforming. Anything above 10 is usually a qualification problem upstream.

Cost per SQO, not cost per meeting

Divide the fully loaded program cost (agency fees plus tooling plus internal time) by SQOs delivered. For most consulting firms targeting mid-market accounts, a healthy cost per SQO is between $400 and $900. Above $1,500 and the program is not yet earning its keep. Below $300 and you are almost certainly under-qualifying and creating delivery problems downstream.

• SQOs per seat per month: leading indicator of program health.
• Cost per SQO: efficiency benchmark; trend matters more than absolute number.
• SQO-to-proposal rate: 40 to 60 percent is healthy; below 30 percent suggests qualification gaps.
• Proposal-to-close rate: a sales motion metric; outbound cannot fix a low number here.
• Average contract value of outbound-sourced deals vs inbound: should be within 20 percent if targeting is right.

Watch the lag, not just the level

Outbound creates pipeline 60 to 120 days before that pipeline becomes revenue. Judging a program at week 6 is judging the engine before the car has left the driveway. Set explicit checkpoints: at 30 days, infrastructure and messaging quality. At 60 days, first SQOs and reply quality. At 90 days, SQO consistency and proposal flow. At 180 days, closed revenue. Cut programs at the wrong checkpoint and you destroy compounding value.

Attribution: be generous in, strict out

Be generous about what counts as outbound-influenced (any account first touched by an outbound channel, even if closed via a referral 6 months later). Be strict about what counts as outbound-sourced (first meaningful conversation came directly from an outbound touch). Most consultancies under-credit outbound by conflating the two. The accurate picture is usually that outbound directly sources 30 to 50 percent of new logos and influences another 20 to 30 percent.

The metric that beats them all: payback period

How many months of outbound spend does it take to recover the gross margin from outbound-sourced deals closed in that period? For a healthy program targeting consulting engagements above $50k, payback should land between 4 and 9 months. Once payback drops below 6 months consistently, the only correct action is to scale spend. Once it rises above 12, pause and diagnose before adding more budget. The two most common diagnoses are a weak ICP filter and broken email deliverability.
