There are 8 main ways to find new B2B clients: referrals, founder sales, trade fairs, a sales team, paid ads, an outsourced sales partner, automated outreach and affiliate partners. Referrals are usually the strongest, but they cap out. The most scalable way in 2026 is automated outreach with tools and AI, run in-house or by a partner. Here is what each way costs.
What B2B lead generation includes
B2B lead generation is the work of finding companies that fit, reaching the right people inside them and turning interest into booked meetings. It is a chain of 5 jobs, and a gap in any of them stops the deals.
| Job | What it means | Usual owner |
|---|---|---|
| Market research | Define the ideal client and count how many exist | Founder or Head of Sales |
| Lead list building | Find the companies and the decision makers inside them | SDR plus data tools |
| Outreach | Email, LinkedIn, phone, ads, events | Sales team, marketing or a partner |
| Qualification | Check need, budget and timing | SDR or salesperson |
| Appointment setting | Book the call into a salesperson's calendar | SDR or partner |
After the meeting, your own team runs the proposal, negotiation and closing.
8 ways to find new B2B clients, with costs
Every way to find clients trades money for time or control. The table compares them on cost, speed and their main limit.
| Way | What you pay for | Time to first meetings | Main limit |
|---|---|---|---|
| 1. Referrals | Your time to ask, sometimes a thank-you | Unpredictable | Caps out, weak in some niches |
| 2. Founder sales | Founder time, club fees, Sales Navigator from about $120 a month | Weeks | Stops when the founder is busy |
| 3. Trade fairs | Stand space from €319 per m² at a large German fair, plus build, travel and staff | 1 or 2 fairs a year | Leads go cold after the fair |
| 4. A sales team | Average gross wage in Lithuania €2,480 a month per person, plus taxes, tools and management | Months: hiring plus ramp-up | Slow to hire, hard to replace |
| 5. Paid B2B ads | Ad budget plus a marketer, consultant or agency | Weeks to test | Stops when the budget stops |
| 6. Outsourced sales partner | A monthly fee or a project, quoted per scope | Weeks | Choosing the wrong partner |
| 7. Automated outreach | Data, email and LinkedIn tools, plus the skills to run them | Weeks once set up | Spam folders if done badly |
| 8. Affiliate partners | A share of each deal they bring | Months to build | Needs careful selection |
Facts checked by AI research on 23 October 2026.
1. Referrals
Referrals are often the strongest channel in B2B. The leads are the warmest, and the cost per new client is the lowest of any channel. The problem is the ceiling: referrals cap out, you cannot plan a quarter on them, and in some niche businesses they barely work.
2. Founder sales
The founder's network, networking clubs and business associations bring warm leads, because people buy from people they know. LinkedIn Sales Navigator helps the founder grow that network and find warm paths: who in your connections can introduce you. Core starts from about $120 a month per seat on monthly billing, before VAT, and prices vary by region (LinkedIn, 2026). The limit is the founder's calendar.
3. Trade fairs
Fairs still work for manufacturers, but each conversation is expensive. At productronica 2027 in Munich, a row stand costs €319 per m² plus a €1,150 communication fee, before VAT (productronica, 2026). A 20 m² stand is about €7,500 in space and that fee alone, before construction, flights, hotels and 3 to 4 days of your team.
4. A sales team (business development)
The average full-time gross wage in Lithuania was €2,480 a month in Q4 2025, according to Sodra data reported by LRT (LRT, 2026). Experienced B2B sellers often ask for more, and you add employer social insurance, tools and management time. The bigger cost is time: recruiting, then months before the pipeline fills.
5. Paid B2B ads
Google Ads catch buyers who already search for what you sell. LinkedIn Ads reach decision makers by job title, industry and company size. Ads can be run in-house by your marketing team, by a consultant or by an agency. You pay for clicks plus the people who manage them, and leads stop when the budget stops. In small B2B niches, search volume can be too low for Google Ads alone.
6. Outsourced sales partner
An outsourced sales partner brings people, tools and process at once. Pricing models differ: a monthly retainer, pay per meeting or a fixed project. Compare what is included, not only the fee: research depth, channels, who handles replies, and whether you keep the data and domains. Our comparison of B2B sales agencies in Lithuania shows how much scope differs.
7. Automated outreach with tools and AI
This is the newest way, and the most scalable. Data tools find the right companies and people, AI researches each buyer, and personal emails and LinkedIn messages go out on schedule. The founder can run it, the sales team can run it, or an outsourced partner can bring a working setup from day 1. In our work with Lithuanian sales teams, many have not yet used the more advanced tools of 2026, so skills are the real cost. Instantly reports an average cold email reply rate of 3.43% in 2026 (Instantly, 2026). Our cold email infrastructure guide covers the setup. Lean Sales Systems can run it for you, train the founder or train your sales reps.
8. Affiliate partners
Affiliate partners refer their own contacts to you for a share of the deal. For lower-ticket offers, affiliate marketers can work well. For complex, high-ticket B2B deals, you need a few carefully selected partners who serve your audience, trust you and earn a good percentage of every deal they refer. These partners need nurturing, like clients. Companies often hire an outsourced sales partner to find them, and we help clients find affiliate partners too.
How to choose and start
Choose by market size and how fast you need new clients. Keep the warm channels running, and add at least 1 channel you can scale on purpose.
| Your situation | Best next step |
|---|---|
| Referrals and the founder's network bring most deals, but growth stalls | Add automated outreach, run by you, your team or a partner |
| Fewer than 400 target companies | Founder sales, referrals and affiliate partners |
| 1,000+ contacts in 1 or more markets, clients needed this quarter | An outsourced sales partner or automated outreach |
| Buyers actively search for your product | Google Ads, with LinkedIn Ads for retargeting |
| Your buyers meet at 1 or 2 key fairs | Fairs, with outreach before and after |
| You need someone to negotiate and manage accounts | Hire a salesperson, and give them a system that fills the calendar |
Whichever way you pick, start small:
- Count your market by country, industry and company size.
- Pick 1 offer and 1 market for the first test.
- Set up tracking, and for email, separate sending domains.
- Run for 21 days, then review replies, objections and meetings.
- Move what works to the next market.
Mistakes that make lead generation expensive
Most wasted budget comes from a few repeat mistakes. Each one has a price.
| Mistake | What it costs |
|---|---|
| Relying only on referrals | Growth stops when the network runs dry |
| Hiring a salesperson before there is a process | Months of salary spent building lists by hand |
| Buying tools nobody knows how to use | Licences paid, no meetings booked |
| Sending cold email from the main company domain | Spam folders, and your normal client emails at risk |
| A trade fair with no follow-up plan | €7,500 or more spent on a stack of business cards |
Buyers also avoid sales calls more than before: 67% of B2B buyers prefer a rep-free experience, according to a 2025 Gartner survey of 646 buyers (Gartner, 2026). A useful, specific first message matters more than a louder pitch.
What this looked like for our clients
Automated outreach turns a market list into a steady flow of opportunities. These are published results from our case studies.
| Client | Industry | Result |
|---|---|---|
| Fore Logistics | Sea freight | 166 opportunities in 5 months |
| WhyAI | Professional training | 700+ C-level replies, 194 opportunities in 2 months |
| Ergovent | Manufacturing, Lithuania | Kaunas to 24 European countries in 15 weeks, 53 interested leads |
In each case, the system researched decision makers, wrote personal messages on email and LinkedIn, and passed interested buyers to the client's team. Our average client researches 10,000 decision makers and gets 500 to 1,000 replies, 100 to 200 opportunities and 8 to 36 closed deals in the first quarter. Results depend on the market, the offer and the deal size.

FAQ
What is the cheapest way to find B2B clients?
Referrals, because the trust is already there and you pay little or nothing per lead. They cap out, though. Among the channels you can scale on purpose, automated outreach usually costs the least per meeting once it is set up well. Compare cost per opportunity, not the monthly fee.
How much does B2B lead generation cost?
It depends on the way you choose. A salesperson in Lithuania starts from the €2,480 average gross wage, plus taxes and tools. A stand at a large German fair can cost €7,500 or more in space alone. Ads cost a budget plus management, and outsourced partners quote per scope.
Can a founder run automated outreach alone?
Yes, if they have time to learn the tools and handle replies. Many founders start that way, then hand it to a salesperson or a partner once it works. At Lean Sales Systems we can run it for you, or train the founder or your sales reps to run it in-house.
Do affiliate partners work for B2B?
Yes, but they take work. For complex deals, pick a few partners who serve your buyers and trust you, agree a fair share of each deal, and nurture the relationship. A few strong partners beat a long list of passive ones.
Is cold B2B outreach legal in the EU?
It can be. GDPR Recital 47 says direct marketing may count as a legitimate interest, and the EDPB lists 3 tests: a real interest, necessity and a balancing test (EDPB, 2024). National e-privacy rules also apply to email and can require consent in some countries. Always offer an easy opt-out. This is not legal advice.
Should we hire a salesperson or outsource?
Hire when you need someone to negotiate and manage accounts. Outsource when the gap is a steady flow of new conversations. Many companies do both: the system fills the calendar and their people close. Read more on when sales outsourcing makes sense.
Bottom line
Referrals and the founder's network bring the best clients, but they cap out. Fairs, ads, a sales team, partners and affiliates each add reach at a different cost. Automated outreach, run in-house or with a partner, is the most scalable way to fill the calendar in 2026.
