Corporate creditworthiness: what banks and suppliers assess and how to improve your ZEK profile

Practical guide for entrepreneurs and finance managers who want to strengthen their company's financial reputation and access more favorable credit terms.

Why creditworthiness matters for a Swiss SME

A company's creditworthiness is not limited to applying for a bank loan. In Switzerland, banks, leasing companies, suppliers offering deferred payment terms, and even business partners regularly review information on a company's financial profile before granting credit, increasing invoicing limits, or accepting new contracts.

The reference system for individuals and, in part, for businesses is ZEK (Zentralstelle für Kreditinformation), the central credit information office based in Zurich. For SMEs, however, credit assessment is based on a broader set of sources: approved annual accounts, Commercial Register data, payment history, insolvency reports, and information collected by commercial rating agencies.

A solid credit profile translates into lower interest rates, higher credit limits, more favorable payment terms with suppliers, and greater flexibility in commercial negotiations. Conversely, late payments, weak balance sheets, or negative reports can block access to credit precisely when the company needs it most.

What is ZEK and what the corporate profile contains

ZEK collects and manages data relating to credit relationships. For individuals, the profile includes credit contracts, leasing agreements, credit cards, and delinquency reports. For businesses, the picture is more complex and does not boil down to a single "ZEK score" as it does for private individuals.

ZEK data relevant for SMEs

  • Credit and leasing contracts held by the company or personal guarantors
  • Rejected or pending credit applications
  • Default reports and debt recovery proceedings
  • Information on personal guarantees from shareholders and directors

Other assessment sources

  • Approved annual accounts and balance sheet data (Art. 958 CO)
  • Commercial reports (Creditreform, Intrum, Dun & Bradstreet)
  • Bill protests and debt enforcement proceedings (Betreibung)
  • Payment history with suppliers and financial institutions

In practice, when a bank assesses an SME, it cross-references ZEK data relating to shareholders and guarantors with analysis of the company balance sheet and any negative reports held by commercial agencies. An entrepreneur with a clean personal credit record but a struggling company will still receive unfavorable terms — and vice versa.

What banks assess

Swiss financial institutions apply proprietary scoring models, but with substantially convergent criteria. For SMEs, the analysis focuses on four dimensions:

Dimension Key indicators Guide threshold
Equity strength Equity-to-total assets ratio, reserves, undercapitalization Positive equity and ≥ 20–30% of total assets
Liquidity and cash flow Current ratio, quick ratio, operating cash flow Current ratio ≥ 1.2; positive operating cash flow
Profitability EBITDA, net margin, multi-year earnings trend Positive EBITDA for at least 2 consecutive fiscal years
Credit behavior ZEK profile, negative reports, payment history No defaults in the last 24–36 months
Sector and structure Sector risk, company age, customer concentration At least 2–3 years of continuous operations

Banks pay particular attention to consistency between official accounting data and the actual situation. Balance sheets showing rising profits but declining liquidity, or net assets eroded by excessive distributions to shareholders, raise questions and can lead to a downgrade of the internal rating.

What suppliers assess

Suppliers offering payment terms of 30, 60, or 90 days do not have direct access to the ZEK profile, but rely on commercial information agencies and their own internal history. The assessment is faster but no less decisive:

First order and new customer

The supplier consults a commercial report (typical cost CHF 30–80) summarizing the balance sheet position, any protests, enforcement proceedings, and a composite rating. With no track record, the initial credit limit is generally conservative: often equivalent to a single invoice or a symbolic amount until trust is established.

Ongoing relationship

After 6–12 months, the supplier primarily assesses payment punctuality. Paying within contractual terms — not necessarily in advance — is the most relevant factor for obtaining higher limits and better conditions. Delays of even a few days, if repeated, are recorded and shared among commercial credit agencies.

Negative report

A supplier can report a defaulter to commercial agencies after failed recovery attempts. This report is visible to other creditors and can block trade credit for months, regardless of the company's overall financial strength.

Red flags that damage the profile

Certain situations have a disproportionate impact on perceived creditworthiness, even when business operations are healthy:

!

Bill protests

They remain accessible for a long time and are detected by banks and suppliers. Even a single protest for a small amount damages the profile.

!

Debt enforcement proceedings (Betreibung)

If no objection (Rechtsvorschlag) is filed within 10 days of service of the payment order, the creditor may proceed with enforcement after 20 days. Entries in the enforcement register remain visible to third parties for up to 5 years (Art. 8a SchKG).

!

Personal guarantees in default

If a shareholder has personal ZEK defaults, banks require additional guarantees or refuse corporate credit.

!

Chronic undercapitalization

Negative net assets or equity below the minimum share capital signals over-indebtedness risk to every assessor.

!

Late annual accounts

Late approval of the annual accounts or inability to provide up-to-date financial statements upon request constitutes a negative signal for banks and rating agencies.

!

Excessive revenue concentration

Depending on a single client for more than 40–50% of revenue increases perceived risk and lowers the commercial rating.

How to concretely improve your credit profile

Strengthening creditworthiness is a process that requires consistency over time. Here are the highest-impact actions, listed in order of priority:

1. Ensure absolute payment punctuality

The single most influential factor is paying invoices, bank installments, leasing payments, and taxes on time. An automatic reminder system and regular bank reconciliation drastically reduce the risk of oversights that generate negative reports.

With accounting software such as Accountex, you can set up automatic payment schedules for suppliers, AHV, and taxes, monitor the status of every payment, and immediately identify overdue items before they become a credit problem.

2. Maintain a solid balance sheet and approve it on time

Ensure that net assets remain positive and that at least 25% of total assets is covered by equity. Avoid distributing dividends that erode reserves when liquidity is already under pressure. Approve the annual accounts within 6 months of the end of the fiscal year (Art. 958 para. 3 CO) and make them available upon request from banks and creditors with a protected interest.

3. Review your ZEK profile and correct errors

Shareholders and directors can request a written copy of their ZEK data (Art. 25 FADP). In principle the request is free of charge; a fee may apply if an identical extract was already provided in the last 12 months without changes (Art. 19 OPDa). Verify that the data is correct: settled contracts still reported as active, incorrect amounts, or outdated reports should be disputed in writing, normally with the reporting institution.

4. Communicate proactively with creditors

If you anticipate temporary difficulties, contact your bank and suppliers before the due date. An agreed repayment plan avoids protests and negative reports, which remain on the profile for a long time even after the issue is resolved.

5. Diversify funding sources

A company that depends on a single credit instrument (for example, an overdraft facility alone) appears more fragile. Combining equity, medium-term bank credit, and leasing for investments signals mature financial management to assessors.

The role of orderly accounting in the credit profile

Up-to-date accounting compliant with Swiss accounting standards (Swiss GAAP FER) is not just a legal obligation: it is the documentary basis on which banks and rating agencies build their assessments. Consistent balance sheets, timely reconciliations, and reliable financial reports accelerate credit approvals and strengthen credibility with suppliers.

Operational checklist with Accountex

  • Close the fiscal year on time and approve the annual accounts within 6 months (Art. 958 CO)
  • Monitor the current ratio and liquidity position weekly
  • Automate reminders for tax deadlines, AHV, and supplier payments
  • Reconcile bank transactions within 48 hours to immediately identify anomalies
  • Generate accounts receivable and payable aging reports to anticipate liquidity pressures
  • Document payment agreements with creditors directly in the accounting system

Rights of the company and its owners

The Federal Act on Data Protection (FADP; RS 235.1), the ZEK regulations, and, for consumer credit, the Consumer Credit Act (CCA) protect the rights of those subject to reporting. It is useful to know them in order to defend your profile:

Right Detail
Free access In principle free of charge; a fee may apply if already provided in the last 12 months without changes (Art. 25 FADP and Art. 19 OPDa)
Correction of incorrect data Right to rectification (Art. 32 FADP); normally through the reporting institution; response to access requests within 30 days
Deletion Under ZEK regulations: normally 3 years after contract closure; up to 5 years for serious defaults or losses; 2 years for rejected applications
Access to data Ability to request a written ZEK/IKO extract in writing and find out which data is recorded (Art. 25 FADP)
Commercial reports Agencies must ensure accuracy and allow correction of material errors (Art. 32 FADP)

Building financial reputation over time

The creditworthiness of a Swiss SME is built month by month through timely payments, transparent balance sheets, and disciplined financial management. The ZEK profile and commercial reports are not bureaucratic barriers, but reflections of the company's economic health — and they improve quickly when management is consistent.

Starting by reviewing your ZEK extract, verifying that accounting is up to date, and putting automatic controls in place for payment deadlines are the three most effective and zero-cost steps to strengthen your credit profile. For SMEs that want to integrate these controls into their daily administrative routine, structured accounting software such as Accountex provides the visibility needed to make informed financial decisions and maintain the trust of banks and suppliers.
