Nearly every answer to how to get B2B leads is about volume. More outreach, more lists, more forms, a bigger top of the pipeline. Volume is the easy part and it is measured on the wrong axis. The number that decides whether any of it works is how many months pass between the day you spend a dollar to win a client and the day that dollar has come back to you. Across 342 business software companies, the median is 16 months 1.
If you sell to other businesses, whether that is software, accounting, consulting, staffing, or managed IT, that lag is the thing that sets your ceiling on what a lead is allowed to cost. Get it wrong and you can run a lead generation effort that produces plenty of leads and still walks the company into a cash squeeze.
Sixteen months, six months, and two years are three different companies
The same study found the top quarter of companies recovering their acquisition spend in six months or less and the bottom quarter waiting two years or more 1. In plain money terms, the fast quarter can win a client in January and be whole by June. The slow quarter is still underwater on that same client the following December, financing the gap out of whatever cash the business has lying around.
That gap changes what you should do about lead generation more than any tactic does. A six-month payback lets you spend aggressively into anything that produces qualified conversations, because the money keeps coming back fast enough to fund the next month. A two-year payback means every additional client you win makes your bank balance worse before it makes it better, and growth becomes something you have to be able to afford rather than something you can simply decide to do.
We used the same benchmark from a different angle in how to set a SaaS marketing budget, where the question was how much of revenue to spend. Here the question is narrower. How much can one lead cost.
Your price list already decided most of this
Companies charging under $5,000 a year per customer get their money back in about 11 months. Companies in the $50,000 to $100,000 range wait 22 1. Double the price and the payback gets worse, which is the opposite of what most owners assume when they move upmarket.
The reason is that big deals are closed by people over months of conversation, and those months are paid for whether the deal lands or not. The proposal, the second call, the security questionnaire, the pilot, the procurement review. All of it happens before a single invoice goes out, and all of it costs salary.
So a firm selling $4,000 engagements and a firm selling $80,000 engagements should not buy leads the same way, and yet they get sold the same package by the same vendors at roughly the same price per meeting.
What one lead is allowed to cost you
Our published band for consulting and professional services puts an inquiry between $60 and $190, with $110 at the median and a typical close rate of 20%, which you can see alongside your own numbers on the consulting lead cost page. At the median that is five inquiries and $550 in advertising to sign one client. At the top of the band it is $950.
Now the version that does not flatter anyone. Assume a consulting practice that buys leads from a vendor rather than generating its own, pays $190 apiece because the vendor calls them qualified, and closes 8% of them instead of the 20% typical of leads that came looking for you. That is 12.5 leads and $2,375 to sign one client. Assume the engagement is a one-off $3,000 project at a 40% margin after the consultant’s time, so it contributes $1,200. The firm is $1,175 in the hole on the client it just celebrated, and the hole is invisible for months because the invoice went out and the bank balance went up.
Change one input and it flips. Same $2,375 in acquisition cost, but the client signs a $2,500 monthly retainer at a 45% margin, contributing $1,125 a month. Now the client is paid for inside three months and the firm should buy every lead the vendor has. The advertising did not change. The engagement structure did, and that is the lever most professional services firms have never touched.
Most B2B lead generation vendors sell calendar entries
A booked meeting is inventory you have already paid for and have not yet sold, and the entire appointment-setting industry prices it as though it were revenue. The same goes for contact lists sold by the record, intent data sold by the account, and any package quoted as fifteen qualified meetings a month. Every one of those is priced on delivery, and delivery is the part that carries no risk for the seller.
Here is the one thing to make a vendor prove before you sign. Ask them for three current clients in your price range, and for each one, three numbers: leads delivered, clients signed from those leads, and the number of months between the two. Not case studies and not logos. Three numbers, three clients. A vendor genuinely producing pipeline has those figures in a spreadsheet already, because their own renewals depend on them. A vendor selling meetings will tell you their clients do not share that data, which is itself the answer.
We publish our own fees on the services page partly for this reason. A retainer you can see is easier to hold against a signed-client count than a per-meeting price that hides how many meetings it takes.
Where the next ten clients come from at these payback lengths
Two sources survive a long payback, and they are the ones that look slowest on a whiteboard.
The first is search capture on the exact phrases a buyer types when the need is already named. Somebody typing “outsourced CFO for construction company” or “SOC 2 readiness consultant” has a budget holder behind them and a project in motion. The volume is small and the cost per click is not, but the close rate on that traffic is the 20% end of our published band rather than the 8% end, and close rate is what your payback is made of. This is the spine of how we build accounts for professional services firms in Atlanta.
The second is the list you already own and stopped calling. Proposals that went quiet, and buyers who moved to a new company and now have a new budget. Those people already know what you do and what you charge, which removes the two most expensive months of the cycle. Referrals belong in the same category and cost nothing, which is why they distort every comparison a lead vendor puts in front of you.
Three arguments we get back
Isn’t this self-serving? You sell paid media.
Partly, yes. What we sell is a retainer to build demand inside accounts you own, and it is a bad purchase for a firm whose payback is past 18 months and whose cash position is thin. Below roughly $1,500 a month in ad spend, any competent management fee eats more than half the budget, which is published on our own marketing cost calculator and is a number that costs us work.
Can we just buy a list and email it?
You can, and the cost per contact will look wonderful next to a $110 inquiry. Compare the two on signed clients per dollar over a full sales cycle, which for a $50,000 deal is most of two years, and the list rarely survives the comparison.
How many leads a month should we be targeting?
Work backwards instead. Take the number of new clients you need this year, divide by your close rate on inquiries that came to you, and you have the lead count. If that count is bigger than your search demand can supply, the constraint is your market rather than your marketing, and more spend will not fix it.
Sixteen months is the median and six is the top quarter. Until you can say which of those your own firm is nearer, the $2,375 in that worked example is as defensible as the $550, and nobody selling you leads has any reason to tell you which one you are buying.
