What do you actually buy when you buy B2B leads?
As a rule, you are not buying a finished lead with proven purchase intent, but a list of target companies selected according to defined criteria. A company-data record may contain the company name, postal address, main number, website, industry and region. Personal contact details are included only where agreed, relevant to the purpose and processed lawfully.
A qualified lead arises only when a suitable company shows interest and a meaningful next step is agreed. Terms such as “buy B2B leads”, “buy B2B contacts” and “buy B2B addresses” nevertheless often refer in the market to a company-data selection. B2B lead generation in Switzerland explains how target companies become leads.
What should you consider before ordering?
A usable selection fits your offer, contains the fields you need and is delivered in a format your team can work with. Before ordering, check the target group, scope of delivery, data quality, price, usage rights and correction arrangements.
Describe the target group and exclusions clearly
“All Swiss SMEs” is almost never a usable target group. The University of St. Gallen’s 2026 SME study evaluates provisional 2023 STATENT figures: 626'033 market-oriented companies, of which 99.7 % are SMEs and 89.8 % have fewer than ten employees. These figures show how broad the Swiss business market is. They say nothing about the availability or quality of a list available to buy.
An order should be specific enough to verify, for example: “Fiduciary firms in the Canton of Bern with a public main number and their own website.” Record the business activity, area, language and required company characteristics. Also state exclusions such as existing customers, competitors, unsuitable activities or internal suppression lists.
Specify the required data fields and scope of delivery
Order fields for a specific work step. A long list of columns is not a quality feature. What matters is whether your team actually needs the information for phone calls, direct mail, research or CRM work.
| Planned step | Example of useful fields | Clarify before ordering |
|---|---|---|
| Telephone outreach | Company name, main number, industry, region, website | Which business number should be delivered? |
| Addressed letter | Company name, full address, region, segment | Is the company address complete and usable for post? |
| CRM enrichment | Website, industry, region, existing mapping | How are fields named and duplicates identified? |
| Preparation for personalised outreach | Publicly named person, role, connection to the company | Which personal details are agreed and relevant to the purpose? |
The table shows one possible structure, not a real delivery or a mandatory list. Before ordering, ask which fields are included in the selected offer and how the finished file is structured. The SwissB2B offer page shows an illustrative delivery example with possible data fields.
Assess data quality, currency and sources
Ask how target companies are selected and the agreed fields checked. For a database, it matters when and from which sources it is updated. For order-specific research, what counts is which criteria and fields are checked for the specific delivery.
The Central Business Name Index (Zefix) can confirm register data for a legal entity entered in the Commercial Register. It does not reliably show whether a business is operationally active, nor whether other information such as website, business number or activity profile is current. Registers, company websites and directories serve different purposes. General claims such as “millions of contacts” therefore do not replace a clear description of the selection and checking process.
Compare price, follow-up work and scope of service
The lowest-priced option is not automatically the cheapest solution. Unsuitable industries, missing fields and unconsidered exclusions shift work to your team. Compare the same task: selection criteria, included fields, research or database access, export, scope of use, corrections and support.
A smaller, appropriately researched selection can be more economical than a large file your team has to cleanse first. Conversely, database access can make sense if your team regularly searches and exports itself. SwissB2B packages and price ranges show which services are included in the commissioned research.
Clarify format, usage rights, duplicates and corrections
Before buying, clarify whether you will receive Excel, CSV, platform access or an export. Ask who may use the data internally, how long the agreed usage lasts and whether repeated exports or a subscription are required.
Also define how existing customers, known companies and suppression lists are taken into account as exclusions. Company name, website and address help identify duplicates and different spellings. The offer should state how you can report unsuitable or incorrect records and which correction service is agreed.
When is your own research worthwhile, and when is a purchased selection worthwhile?
Your own research is worthwhile for a small number of strategically important target companies. A prepared selection is worthwhile for many similar companies with a clearly defined target group. Database access suits teams that want to search, filter and export themselves on an ongoing basis.
| Starting point | Sensible approach | Why |
|---|---|---|
| A few strategic target companies | Own research | Your team can understand and prepare each case individually. |
| Regularly changing search requests | Database access | Your team carries out the selection and exports itself. |
| Many similar target companies for a defined assignment | Order-specific company-data selection | The provider researches to the agreed brief. |
| Unclear target group or no planned use | Do not order yet | First define the offer, segment and required data. |
What information belongs in your order?
A good order describes the later use, not only a quantity. This information creates a verifiable basis for the quote and delivery:
- Your offer and why it fits the target group sought
- Business activities to include and exclude
- Cantons, regions, cities, postcodes and required languages
- Company characteristics such as size, legal form or further selection criteria
- Required data fields and preferred delivery format
- Existing customers, suppression lists and other known exclusions
- Planned contact channel and responsible internal contact or team
Example of a usable brief
“We offer cybersecurity consultancy for fiduciary firms. We are looking for fiduciary firms in the Canton of Bern and the City of Zurich with their own website and business main number. We exclude existing customers, management consultancies without an identifiable fiduciary offering, and companies outside the area. We require an editable Excel and CSV file.”
The brief links the offer, target group, exclusions, fields and delivery format. If one of these details is missing, the data provider has to guess part of your sales decision.
What applies to personal data and subsequent outreach?
The Federal Act on Data Protection (FADP) protects the personal data of natural persons. Business details also fall within its scope where they identify or make a person identifiable, such as a name, direct-dial number or personal email address. For a sole proprietorship, the company name and business details may already identify the owner.
Buying or publishing contact details is not blanket authorisation for every form of outreach. Phone, email, direct mail and platforms are subject to different rules. The cold outreach in Switzerland guide sets out the contact channels and relevant Swiss rules.
Which sources and method does this guide use?
The market figures come from the University of St. Gallen’s 2026 SME study, which evaluates provisional 2023 STATENT figures. For register data, the guide refers to Zefix and, for personal data, to the Federal Act on Data Protection (FADP).
These notes are a practical purchasing aid, not a quality ranking or legal advice. Zefix confirms register information for registered legal entities, but neither operational activity nor the quality of a data delivery. The University of St. Gallen figures describe the market and do not permit conclusions about the currency, completeness or campaign success of a specific list.
At SwissB2B, a company-data selection is researched for the order according to the agreed criteria and fields. Details are checked manually and delivered as an editable Excel or CSV file. This working basis guarantees neither purchase intent nor conversations or completed sales. Your team remains responsible for checking the selection, lawful use and outreach.
Conclusion: Buy a suitable working basis
A company-data selection makes sense where the target group, fields, scope of delivery, usage and correction arrangements are clear before ordering. The decisive question is: can your team work meaningfully with the selected companies using the information delivered?
Once the criteria are defined, you can have company addresses researched to your criteria. The offer page explains the selection, scope of delivery and ordering.
