How to build a Swiss B2B target-account list

A useful Swiss B2B prospect list gives your sales team a reason to research each company. Start with the offer you sell and define which businesses could use it. Estimate the size of that market, collect candidates, then check the evidence before handing accounts to sales.

For a concrete example, take a seller of quality-management and production-planning software for manufacturers. Prospex used that sales brief to build a Swiss precision-manufacturing list. The example and review decisions below come from the snapshot of 12 August 2026. They describe the evidence available then; company details need a fresh check before outreach.

1. Turn the sales brief into an ideal customer profile

The brief called for Swiss manufacturers of machinery, precision components, and medical or measurement instruments that produce in Switzerland and sell to other businesses. It covered the whole country, with size filters of 11–50 and 51–500 employees and customer audiences classified as B2B or mixed.

The seller’s software makes production processes relevant to the search. A distributor can sell the same instruments while having a different operating need. Write down the activity you need to verify, and keep your own offer separate from the description of the companies you want to reach.

A worksheet for this brief

Criterion	Include or exclude	Evidence to record
Operating activity	Include manufacturers of the specified products. Exclude businesses whose relevant activity is distribution or laboratory services.	Company pages describing products and manufacturing work.
Production location	Require production in Switzerland; the brief allows every canton.	A named Swiss production site. Record the registered office separately.
Customers	Include B2B and mixed audiences with a relevant business-customer activity.	Customer sectors, applications or named business references.
Size	Target the selected 11–50 and 51–500 employee bands.	Source, date and whether the band is estimated. Keep missing evidence unresolved.
Account identity	Review the operating entity that could buy the software. Exclude your own competitors.	Legal name and UID, with the website and group relationship checked.

Copy these criteria into your working sheet and adapt them to your offer. Add a language-coverage field: a national brief requires research across language regions and a plan for serving the accounts you select. The example had no cantonal restriction; a regional sales team should state its territory explicitly.

The Swiss ideal customer profile template extends these five criteria to a full worksheet with fields for language regions and exclusions, and shows two completed profiles, for a recruitment agency and an IT services firm.

Use separate columns for a sourced fact, an estimate and a missing detail. For example, a production-site page can support location, while an estimated employee band remains an estimate. If a size limit is essential to your offer, hold the account for research until the evidence is sufficient.

2. Estimate the market before setting a list target

Build a candidate pool with the criteria your sources can support. Record the population covered and the date of the search. Review a random sample against the full brief, keeping confirmed fits and unresolved cases separate. This gives you a basis for an estimate and shows which criteria require further research.

The Swiss target-market sizing guide works through a register-based estimate and the limits of each filter. Apply that method to the manufacturing brief before deciding how many accounts the team can realistically work.

In the reviewed product snapshot, 499 companies remained in Core after one exclusion, and 500 were in Explore. These counts describe candidates within that particular build; they do not measure the total number of Swiss manufacturers that meet the brief. Estimating the whole market requires a separately defined population and a reviewed sample.

3. Discover companies from the same brief

Use the written profile to search company websites and relevant industry directories. Search for the specific products and production activities in the languages of your target regions. Keep the source beside each candidate so that a colleague can retrace the match.

For this brief, a page about manufacturing measurement instruments is useful evidence. A page selling imported instruments needs a further check for local production. Record candidates under the same criteria even when they arrive from different sources, and use the UID to identify repeated legal entities.

The published Prospex example was built from its description and filters, with no example customers added. When you already have customers who bought for a shared reason, you can also use them to sharpen discovery. The guide to finding similar Swiss companies explains how to choose a coherent seed group and test the results.

Keep companies with several activities under review when one activity fits. For a group website, check which legal entity operates the relevant production site. Shared branding alone leaves the buying account unresolved.

4. Review the list before outreach

Before a company reaches sales, give it one of three decisions: accepted, rejected or unclear. Record the criterion it fails or still lacks, with the source and the date you checked. Here "accepted" means the activity fits the brief; the buying team and purchase intent are qualified later. When a mandatory criterion has no evidence yet, such as the production site or the size band, the company stays unclear until you find it.

Decisions from the manufacturing review

The review of 12 August 2026 recorded the cases below. They describe the evidence on that date. An unclear decision becomes a research task, even for a company the original build kept in Core.

The same review drew a reproducible random sample of ten Core companies, after excluding the orthopaedics distributor, and found three wrong matches and one borderline case. The first twenty Core rows had looked better, with three evidence or classification problems, so a check of the top of the ranking alone would have hidden the matching problem. Ten companies are too few to give an accuracy rate for the product.

Sample the list and fix the errors that repeat

Review ten companies at the top of the results, ten around your planned cutoff and ten below it, then draw a separate random ten from the whole list. Keep each sample's results apart and note how it was drawn. When several rejections share a cause, change that part of the brief or one filter, run the search again, and review the changed rows along with a fresh sample. In the manufacturing review, four causes came up:

• Right sector, wrong activity: a dealer matches "machinery". Ask for evidence of manufacturing, and review separately each dealer that also produces.
• Right words, wrong product: "medical" brings in pharmaceutical manufacturers. Name the product and its use in the brief.
• Right group, unclear entity: a parent company's factory says little about what its Swiss subsidiary buys. Check the local operation.
• Thin evidence: a broad registered purpose gives you a lead to research. Keep the company unclear until its activity is documented.

Look for good companies the search missed

Keep a few companies you know fit out of your examples, then look for them in the results and below the cutoff. In Prospex, an unknown size, sector or customer audience never removes a company: it stays in the list, and its row shows what is not known yet. Canton and commune are strict filters, and companies in liquidation stay out unless you include them. For a known company that is missing, compare its canton, its commune and any known size or sector with your filters. Then compare its own description with the words of your brief, in German and French, and in Italian if you sell in Ticino.

An association directory for your sector, or another independent list, gives you more companies to check. Review them against the same brief before you record one as missing. Known companies show you where the search falls short, but they cannot prove that the list is complete.

A review sheet

Keep one row per company in a spreadsheet, with these columns: company and UID, position in the results, decision, reason or failed criterion, evidence URL and date, missing evidence, next action, owner. Keep the rejected rows with their reasons, so you can check the next search for the same mistakes.

5. Hand over a list that another person can use

Give each unclear account a research task and an owner. For each account you hand to sales, retain enough evidence for the next person to understand the decision:

• Legal name, UID, website and relevant operating location.
• Fit reason tied to the brief, with source URLs and the date checked.
• Estimated fields and outstanding questions, including size or group ownership.
• Account owner and next action, with existing CRM relationships checked.

A verified manufacturing activity supports account selection. It does not prove that a company wants new software. Research the responsible team and its current situation before preparing a relevant approach. Keep the account-selection decision separate from a sales opportunity. The account research template takes each accepted company from there.

For recruitment, the operating need and the buyer change. Use the Swiss recruitment-agency client-acquisition guide to apply the process to employer accounts.

Use the brief in Market Builder

See the reviewed manufacturing example in Market Builder, including its filters and dated company sample. Use your own offer to write a brief, then review the reasons behind the returned candidates with the worksheet above.
