Why contracts grow a company faster than jobs
A domestic job pays once. A commercial contract pays every month — and a business built on contracted revenue compounds in ways one-off work never can.
-
Win recurring work
Commercial buyers place recurring contracts — maintenance, servicing, supply, cleaning. One win keeps paying: our steel fabrication client's largest single ads-won contract is worth £80,000 a month, ongoing.
recurring > one-off
-
Bank the revenue
Contracted income is predictable — which makes it bankable. One client is using contracted fleet work to raise credit against, funding expansion that one-off jobs could never support.
contracts are collateral
-
Step up the ladder
The multi-million contracts go through formal tenders — Google Ads won't win those, and we say so. What it wins is the medium, recurring work that builds the track record and capacity to reach that table.
honest ceiling, stated plainly
The economics that make it work: a commercial electrical click costs £6.38; an "electrician near me" click costs £6.46. Same click price — one buys a call-out, the other can buy a contract. UK Google Ads data (DataForSEO), July 2026.
Two ways we generate leads
B2B contract sourcing is the specialism. Consumer lead generation is where several of our published results come from — both are here, on purpose.
B2B contract sourcing
For service businesses that could sell to business: fabricators, commercial trades, cleaning and grounds firms, fleet workshops. We put you in front of the buyer with the contract.
- Buyers: procurement, project, facilities & fleet managers
- Leads arrive as emails, drawings and phone calls
- Clients typically close 30–50% into qualified work
B2C lead generation
Appointments, quotes and jobs from consumers — for dentists, estate agents, clinics, trades and practices. Still no ecommerce, anywhere on this site: check the sitemap.
- Consumer verticals with their own dedicated pages
- Free calculators to model a budget before you spend
- Published results, sourced — £19.97 cost per lead at £10k/mo
How we put you in front of the buyer
Commercial buyers are busy, not loyal. They search for a specific solution and go with whoever makes their job easiest — so we engineer the path of least resistance, straight to your door.
-
The search
A procurement, project or facilities manager has a problem to place — and searches for the specific solution. Smaller volumes than consumer search, far more valuable clicks.
input: real buyer demand, measured
-
The page
They land on a page built for that exact problem — not a generic brochure. Drawing, plan and spec upload means they never have to write a brief: they hand over what they already have.
zero-friction enquiry, by design
-
The contract
Enquiries arrive as emails, drawings and calls — answered in hours, because the first credible response usually wins. From there our clients typically close 30–50% into qualified work.
speed is the closing tool
The full working method — audit, rebuild, measure, scale — is documented on the PPC management page, and the deep version of the B2B approach on the B2B lead generation page.

B2B lead generation FAQs
What is B2B contract sourcing?
Using paid search to put a service business in front of commercial buyers — procurement, project, facilities and fleet managers — at the moment they search for a specific solution, with a dedicated landing page that makes enquiring effortless. The output is not a list of leads: it is enquiries from buyers with recurring commercial work to place. GrowthLine does this for UK service businesses, from steel fabrication to commercial cleaning, and clients typically close 30–50% of these enquiries into qualified work.
Can Google Ads really win commercial contracts?
Yes — with an honest caveat. Commercial buyers do search: UK Google Ads data shows thousands of monthly searches for terms like electrical contractor, office cleaning services and fleet servicing. A well-built campaign captures that smaller, higher-value flow. What Google Ads does not win is the multi-million tender — those go through frameworks and formal procurement. The ads-won contracts are the medium, recurring ones that build the cashflow and track record to reach that table. The full approach is on the B2B lead generation page.
Do you guarantee contracts?
No — and we would be wary of anyone who does. What we can show is what has happened: a steel fabrication client went from one customer to roughly £120,000 a month of recurring contracted work within 30 days, and our clients typically close 30–50% of B2B enquiries into qualified work. Volumes, click costs and sales cycles vary significantly by industry — anywhere from a week to a few months — so tell us your sector and we will give you the honest picture before you spend anything.
Do you still run B2C lead generation?
Yes. B2B contract sourcing is the specialism, but we run consumer lead generation for dentists, estate agents, clinics, trades and professional practices — it is where several of our published results come from, including a £19.97 cost per lead on a £10k-a-month account. The B2C service has its own page, with free calculators that model what a budget could produce in your sector before you spend it.
How do I choose a B2B lead generation agency?
Check claims a website cannot fake: does the agency's sitemap match the specialism it claims, will you own your own Google Ads account, does it report on cost per enquiry rather than clicks, and are its case studies named and sourced. Ask every shortlisted agency — including us — the same questions and compare the answers in writing. Our results are published with sources on the results page, and our comparison pages state plainly where a freelancer or in-house hire beats an agency.
