A B2B company turns on Google Ads, runs it for a month and pulls the report. Twenty quote requests, two of them promising, no orders yet. The owner looks at the spend, looks at the empty revenue column and wonders whether to shut it off.
That report is accurate and almost useless. In most B2B sales, the order that pays for the ads hasn't happened yet when the month closes, and the customer who places it may keep ordering for years. This chapter works out what a B2B lead is worth, what a customer really costs to win through Google Ads, and how to judge the budget on the timeline the sale actually runs on. It builds on the tracking from Chapter 1 and the search priorities from Chapter 2.
Nearly Half of Industrial Purchases Take Six Months or More. A 30-Day Report Sees the Click and Misses the Order.
The sales cycle is the first number to get honest about. In Gardner's 2019 survey of buyers at durable-goods manufacturers, nearly half (48%) of purchase processes took at least six months. For larger purchases the timeline stretches further: 6sense's 2025 study of purchases of $25,000 and up put the average at 10.1 months. Its data also shows physical goods closing about 4.8 months faster than services, so a parts order or a stocked item moves quicker than a managed IT contract or a 3PL agreement.
Those figures cover the whole buying process, and a good part of it happens before the buyer clicks an ad or calls anyone. 6sense found buyers first reach out to a seller about 61% of the way through. Even so, the order usually lands months after the click, and a month-end report can't see it. It sees the click, the lead and maybe the qualified lead, and the order gets credited to whatever month it finally closes in.
So we judge a B2B account on two clocks:
- Every month, on qualified leads and their cost. Chapter 1 made the qualified lead the conversion the account counts, and it shows up within days of the click.
- Over a full sales cycle, on orders and revenue, grouped by the month of the click that started them. A lead from March that closes in September belongs to March's spend.
That second clock is why the won order goes back to Google with its value even though bidding never waits for it. If the budget question comes up in month two, the honest answer is the qualified-lead number, plus a date when the first orders from those leads should be known. Our post on buyers writing next year's budget this month covers the calendar side of the same problem.
Google Ads Leads in B2B Average $75 to $94 Each. A Paying Customer Can Cost Over $11,000.
We size a B2B budget link by link. A click has a price. Some share of clicks turn into leads, sales qualifies some share of those, and some share of qualified leads sign. At the far end sits what a signed customer is worth. Change any link and the answer moves.
Start with the first two links. WordStream's 2026 benchmark report, which averages more than 13,000 search campaigns on Google and Microsoft by category, puts the average click at $5.87 for both its industrial and commercial category and its business services category. Industrial advertisers turned 8.20% of clicks into leads and business services advertisers 4.85%. The same report gives an average cost per lead of $75.19 for industrial and commercial and $93.69 for business services. Those are separate averages across different accounts, so they won't multiply out exactly, but they put the starting point in the right range. Your own click prices can sit far from these averages; the bid estimates in Chapter 2 run from under $5 to more than $70 depending on the search.
Now the rest of the chain, again with published averages so you can see the shape before you fill in your own numbers. One agency, First Page Sage, publishes funnel rates from its own and its clients' data for 2019 through 2025: for manufacturing, 4.9% of leads become sales opportunities and 13% of sales-qualified leads close; for IT and managed services, the figures are 3.0% and 20%.
The two rates measure slightly different stages (First Page Sage counts an opportunity only after a lead is qualified and gets a proposal), so multiplying them gives a cautious, high-side estimate. Put together, 100 leads become about 0.6 customers in either industry. For the manufacturer that is about $7,500 in leads for roughly six-tenths of a customer, or about $11,800 per customer. For the IT firm it is about $15,600.
Those figures will make some owners close the browser. Read them as a shape, not a forecast. The cost per lead is an average across every advertiser in a broad category, and the funnel rates come from one agency's clients. Your own account will differ at every step, which is exactly why Chapter 1's tracking matters: after a few months you replace each average with your own number.
The chain also shows where the money goes. A lead that never becomes an opportunity costs as much as one that does. That is why the qualified lead is the conversion the account counts and, once volume allows, the one Google bids toward, why Chapter 2 puts supplier and quote searches first, and why a later chapter is devoted to keeping job seekers and students out.
Top Job Shops Keep 98% of Their Customers. The First Order Is the Smallest Part of the Account.
The chain only looks expensive until you put the right number at the end of it. B2B customers don't buy once.
An AMT summary of Gardner's benchmarking of top machine shops reports a customer retention rate of 98%. Distributors show the same pattern in their own way: Fastenal, a large public industrial distributor, reported that contract customers made up 74.7% of its sales in the fourth quarter of 2025. In managed IT, Kaseya's 2024 survey of 984 providers found about half of providers charge between $1,001 and $5,000 a month per client.
Take a managed IT firm with a contract at $2,000 a month, a figure inside the most common band, $1,001 to $2,500, and a client who stays three years. That account is worth $72,000 in revenue, against the roughly $15,600 the worked chain above put on winning it. A machine shop customer who sends work for years, or a distributor account that reorders every month, follows the same logic with different numbers.
Two numbers come out of this, and you need both:
- Lifetime value sets the ceiling. It is the most a customer could be worth to win. Use gross profit, not revenue, and be conservative about how long accounts stay.
- The first order sets the floor. If the first order alone covers what it cost to win the customer, everything after it is profit, and you can bid harder with less risk.
Most B2B accounts sit between the two, and the budget conversation gets easier once both are written down. Referrals add to the account value too: a buyer who is happy with a supplier tends to mention it to the next plant manager who asks.
Shops That Quote Within a Day Win 51% of Jobs. Shops That Take Longer Win 41%.
One link in the chain is entirely in your hands: how fast and how well you respond.
In Modern Machine Shop's 2026 Top Shops benchmarking, shops that turn quotes around within a day reported a 51% win rate on new business, against 41% for shops that took longer. The sample is shops that chose to take part, so treat the gap as a direction, not a law. It also matches what buyers wrote in the supplier threads we read, where slow or missing replies were a recurring complaint.
A faster response raises the value of every lead Google sends without changing a single bid. Before adding budget, it is worth asking how long a quote request sits before someone opens it, and whether calls that come in at lunch get answered.
If Your Team Can't Quote Every Lead, a Bigger Google Ads Budget Just Buys Leads Nobody Answers.
The last input is capacity. A B2B company can only quote so many jobs, onboard so many accounts and produce so much. A budget that sends more qualified leads than the team can work through doesn't grow the business; it raises the cost of every customer and burns goodwill with the buyers who wait.
So set the budget from the other end:
- Decide how many new customers you can take on in a month.
- Work back through your close rate and qualified rate to the number of leads that requires.
- Multiply by what a lead costs in your account. Until you have real data, divide the Chapter 2 bid estimates by the conversion rate you expect.
- Divide by 30.4 for a daily budget.
A worked example, with made-up numbers for a small fabricator. The owner says the shop can absorb two new customers a month without hiring. Its own tracking says one qualified lead in four becomes a customer, and one lead in three is qualified. Two customers need 8 qualified leads, which need 24 leads. Twenty-four leads at $90 each comes to $2,160 for the month, which works out to roughly $71 per day. But if the estimator can only turn around six quotes a month, eight qualified leads is already two too many, and the next dollar is better spent on quoting faster than on more clicks.
Google can spend up to twice the average daily budget on a busy day and balances it out over the month, so a daily figure works as a monthly cap in practice. Once your own numbers replace the averages, revisit the budget every quarter, while you keep judging qualified leads every month.

Chapter 4 turns to Ad Rank and Quality Score, and to the landing page: a page about one product or process gives Google a much clearer match than a home page covering everything you make.
