How to Increase Average Deal Size in Consulting

Average deal size in consulting is total fees won divided by engagements won, over the last 12 months. In our worked example of 20 engagements averaging $26,900, scoping a paid second phase into the first proposal lifted it 26%, selling to a more senior sponsor 13% and three-option proposals 8%. A minimum-fee floor lifted it 30% but cut total fees by 9%.

• The metric: average deal size = fees of engagements signed in the last 12 months ÷ number of engagements signed. Track the median beside it, and first-year client value as well.
• The rule: the Average-and-Revenue Test. A deal-size lever only counts if average deal size and total fees both rise.
• The levers, ranked by effect in our example: phase two scoped into the first proposal, a more senior sponsor, three-option proposals, then a minimum-fee floor (which fails the test unless the lost work is replaced).
• The hidden cost: bigger deals need more first meetings with bigger buyers. Replacing six small deals with two mid-sized ones takes about eight extra qualified first meetings at a 25% close rate.
• Not on this page: what to charge per tier. That is covered in our consulting pricing framework.

How is average deal size measured in a consulting firm?

Average deal size in a consulting firm is the total contracted fees of engagements signed in a period, divided by the number of engagements signed, and most firms get it wrong in one of four ways. Use a trailing 12 months, because a single quarter of five deals moves too much to read.

• Retainers: count the contracted term (12 months at $8,000 is $96,000), not one month. Rolling retainers with no term: count 12 months and say so.
• Expenses: exclude pass-through costs such as travel and licences. They inflate the number without changing the work.
• Mean and median: report both. One $250,000 transformation programme can lift the mean for a year while the typical deal stays where it was.
• Phases: decide whether a phase two is a new deal or part of the first one. The choice changes the result, as the worked example below shows.

Our example firm signed 20 engagements in 12 months: six at $8,000, ten at $25,000 and four at $60,000. Total fees are $538,000, so the mean is $26,900 and the median $25,000. Average deal size is only useful if you know which deals moved it.

Which levers increase consulting deal size the most?

Ranked by effect on our example firm, the lever that adds most is scoping a paid second phase into the first proposal. A minimum-fee floor lifts the average most but loses money on its own. Every input below is an assumption chosen to illustrate, not a measured rate; no credible public benchmark exists for how often consulting buyers take an upper option or a second phase.

The phase-two row carries a definition trap. If your firm books phase two as a separate deal, the same $140,000 of new fees shows up as 24 deals averaging $28,250, only 5% up. The revenue is identical; the metric is not. For consulting firms that sell in phases, first-year client value is a truer measure of deal size than average contract value.

The Average-and-Revenue Test: why a minimum fee alone is a trap

The Average-and-Revenue Test says a deal-size lever only counts if average deal size and total fees both rise. A minimum-fee floor is the quickest way to raise the average, because it removes small deals from the denominator, and the only lever in the table that can cut revenue. In our example it raises the average 30% while total fees fall $48,000.

The floor passes the test only when the time it frees is sold again at the higher level. Replacing the $48,000 takes two more $25,000 engagements. At an assumed close rate of 25% from qualified first meeting to signed engagement, that is 8 extra first meetings. At 20% it is 10; at 33% it is about 6. The floor is right for most firms; it just has to come with the pipeline to absorb it, which is where most floors quietly fail.

How do I move from $20k to $100k consulting engagements?

Moving from $20,000 to $100,000 consulting engagements changes who signs, not just the number on the proposal. Each step up the ladder needs a different buyer, a bigger problem, harder proof and a contracting process that can carry it.

The table describes typical patterns, not thresholds any buyer publishes; approval limits vary by company. How the approval path shapes whether a retainer or a project sells is set out in our retainer versus project guide, and the procurement paperwork that blocks six-figure deals in our guide to how boutique consultancies win enterprise work. A consulting firm cannot sell a $100k engagement to a buyer who can only approve $20k.

Does value-based pricing increase consulting deal size?

Value-based pricing is associated with larger consulting deals in survey data, but the data cannot show it causes them. The Consulting Success fees study, a survey of nearly 1,000 consultants, reports that 51% of consultants using value-based fees have an average project value of $10K+, against 39% of those billing hourly. It also reports that 52% of specialists charge $10K+ per project, against 18% of non-specialists, and that 81% of consultants charging $20K–$50K per project are specialists.

Two cautions. The study is self-reported and published by a firm that sells consulting-business coaching, so treat it as directional. And specialists are twice as likely to price on value in the same study, so specialisation and pricing method are tangled together. The practical reading: value-based pricing works when you can name the business number the engagement moves, and that is much easier for a specialist.

Which deal-size lever should I fix first?

Fix the lever your own deal list points to. These checks are our working rules of thumb, not published thresholds; run them on your last 12 months of signed engagements.

What does raising deal size cost in pipeline?

Raising consulting deal size costs pipeline before it pays in fees. Larger engagements take longer to sign, need meetings with more senior buyers, and a floor needs replacement work, about 8 extra qualified first meetings in our example. Doing it yourself means partner time on targeting and outreach to people who do not yet know you, on top of delivery. Our guide to lead generation for boutique consulting firms shows how to build that target list from work you have already delivered.

Firms that hand the meeting-booking part over use a service such as LeadsNow’s appointment setting for consultants, the approach behind 50,769+ AI-booked sales appointments since 2017. The partner still runs the conversation that sells the larger scope; no one else can.

Frequently asked questions

What is a good average deal size for a consulting firm?

There is no reliable published benchmark across firm types; it depends on your sector, buyer and model. One reference point: in the Consulting Success fees study of nearly 1,000 consultants, 51% of those using value-based fees reported an average project value of $10K+, against 39% of hourly billers. Compare yourself with your own trailing 12 months first.

Should I set a minimum engagement size?

Usually yes, but only with a plan to replace the work you turn away. In our worked example, a $15,000 floor raises the average deal size 30% but cuts total fees 9% until two extra $25,000 engagements are won, which takes about 8 more qualified first meetings at a 25% close rate.

How do I move from $20k to $100k consulting engagements?

Sell to a more senior buyer against a bigger problem. A $20k engagement is typically signed by a founder or department head for a defined deliverable; a $100k one usually needs an executive sponsor, a phased programme, sector proof and procurement readiness.

Should I count retainers in average deal size?

Yes, at their contracted term: a 12-month retainer at $8,000 a month counts as $96,000. For rolling retainers with no term, count 12 months and label it, so the number stays comparable from year to year.

Do three-option proposals increase consulting deal size?

They can, when the options differ in scope and outcome rather than only in price. In our illustration, if 3 of 10 mid-sized clients choose a $40k option over $25k, average deal size rises 8%. The take-up rate is an assumption; measure your own over your next ten proposals.
