Why verify your partner's financial strength before signing
A strategic B2B agreement — exclusive distribution, co-development, critical outsourcing, operational joint venture or supply with significant advance payments — can bind your SME for years and tie up liquidity, working capital or fixed-asset investments. Unlike a one-off spot purchase, the partner becomes an integral part of the business model: a default or sudden restructuring means lost revenue, unrecoverable costs and balance-sheet liabilities that are hard to manage.
In Switzerland, where many SMEs operate on tight margins with limited or no audit, counterparty assessment is not a luxury reserved for large companies. The Code of Obligations (CO) protects the contract once signed, but does not replace upfront analysis: a partner's bankruptcy (Art. 191 DEBA) or approved composition agreement (Art. 293 et seq. DEBA) often leaves creditors with only partial recoveries and lengthy proceedings.
This guide outlines a structured financial due diligence process for B2B partners, with tools accessible to Swiss SMEs, solvency criteria and contractual levers to limit exposure before committing capital.
When financial due diligence is mandatory, not optional
Not every supplier requires the same level of scrutiny. In-depth verification focuses on relationships that create economic dependency or balance-sheet exposure:
High exposure
- Advance payments on production, deposits on multi-year contracts or security deposits
- Trade receivables with payment terms beyond 60 days net
- Joint investments in tooling, software or fixed assets dedicated to the partner
- Personal or corporate guarantees issued in favour of the counterparty
Strategic dependency
- Sole partner for a critical component or sales channel
- Contracts with exclusivity, minimum purchase or take-or-pay clauses
- White-label or private-label agreements with dedicated stock
- Subcontracting chains where the partner acts as general contractor
A practical rule for SME owners and CFOs: if the partner's insolvency could jeopardise more than 10% of annual revenue or available working capital, financial due diligence must be documented before signing — even when the counterparty is a well-known company in the sector.
Risk–depth verification matrix
Match the intensity of analysis to the risk profile. The table below proposes three levels consistent with Swiss SME practice:
| Level | Relationship profile | Minimum checks | Indicative timeline |
|---|---|---|---|
| Basic | Annual contract < CHF 50'000, partner replaceable within 90 days | Zefix extract, commercial register check, standard credit report | 1–2 business days |
| In-depth | Exposure CHF 50'000–250'000 or exclusivity clauses | Latest annual accounts, ratio analysis, bank references, pledge/bankruptcy check | 3–5 business days |
| Extended | Joint venture, advance payments > CHF 250'000 or critical partner dependency | Full due diligence with auditor or adviser, projected cash flow, contractual audit | 2–4 weeks |
Information sources accessible in Switzerland
Swiss corporate transparency allows preliminary checks at low cost, before requesting confidential documents from the partner:
Commercial register and Zefix
The official extract (Art. 936 et seq. CO) certifies legal form, share capital, signatories and any bankruptcy or deletion entries. Zefix (zefix.ch) enables centralised search by canton and verifies consistency between company name and UID. Also check any branch offices and recent registered office transfers — possible signs of unreported restructurings.
Official bankruptcy publications
The FOJ publishes bankruptcy notices, composition moratoria and composition agreements on shab.ch. A search by UID or company name of the partner and its majority shareholders reveals past proceedings — relevant information even if the current company is formally different (asset purchase post-bankruptcy).
Credit agencies and ratings
CRIF, Intrum, Dun & Bradstreet and other providers offer reports on solvency, protests, enforcement proceedings and late payments. For Swiss SMEs the cost of a basic report (CHF 30–80) is generally manageable relative to the risk. Compare the rating with the sector average: a mid-range score in an already volatile industry (e.g. construction, events) calls for greater caution.
Partner accounting documents
For significant relationships, request the balance sheet and income statement for the latest closed financial year, any interim statement and notes to the accounts. SMEs not subject to audit may refuse: in that case negotiate at least a signed statement of financial position from the managing director (GmbH) or board of directors (AG), with a truthfulness clause and indemnification for false information (pre-contractual liability; Art. 2 CC).
Solvency analysis: ratios and warning signs
You do not need a master's in corporate finance: a few indicators, calculated from balance sheet data, guide the decision. For unlisted GmbHs and AGs, assess at least these parameters:
| Indicator | Formula | Prudent threshold (SME) | Interpretation |
|---|---|---|---|
| Current ratio | Current assets ÷ Short-term liabilities | ≥ 1.2 | Ability to cover debts within 12 months |
| Debt ratio | Total liabilities ÷ Equity | < 2.0 | Financial leverage and safety margin |
| Working capital coverage | Net working capital ÷ Annual revenue | ≥ 5% | Operating buffer relative to turnover |
| EBITDA margin | EBITDA ÷ Net revenue | Sector-dependent; positive trend | Sustainability of the operating model |
| Share capital vs losses | Uncovered losses ÷ Share capital | < 50% | Proximity to capital loss (Art. 725a CO) |
Red flags not to ignore
- Frequent changes of auditor, registered office or company name in the last 24 months
- Share capital at the legal minimum (CHF 20'000 GmbH / CHF 100'000 AG) with negative or near-zero equity
- Receivables from shareholders or related parties exceeding 20% of current assets
- Systematic refusal to share financial data while requesting advance payments or extended terms
- Recent enforcement proceedings or protests against joint signatories
- Discrepancies between declared revenue and the order volume you intend to place
Contractual risks and asset-protection levers
Financial due diligence is completed with clauses that translate the analysis findings into legal rights. In a strategic B2B relationship, consider at least the following measures:
Guarantees and collateral
First-demand bank guarantee (Art. 111 CO) on advance payments or deposits, pledge over inventory or receivables (Art. 884 et seq. and 899 et seq. CO), or insurance bond. For GmbHs with financially strong shareholders, a joint and several guarantee from the majority shareholder can supplement corporate cover.
Size the guarantee at 100–110% of maximum expected exposure, with a term covering the recovery period in case of early termination.
Conditions precedent and covenants
Make contract effectiveness subject to delivery of guarantees, updated commercial register verification or maintenance of minimum ratios (debt covenants). Provide for annual audit rights over financial data for multi-year contracts.
Include termination clauses for breach (Art. 107 et seq. CO) in case of insolvency proceedings (DEBA), capital loss or over-indebtedness (Art. 725a and 725b CO) or default on payments to third parties.
Payment terms and retention
Limit advance payments to the minimum necessary and stage them against verifiable milestones. For ongoing supply, negotiate payment terms consistent with the risk profile: low-rated partner → payment in advance or on delivery, not 90 days end of month.
Retention (withholding 5–10% until acceptance or end of warranty) reduces exposure on complex contracts without affecting VAT if correctly structured on the invoice.
Liability and governing law
Define liability caps proportionate to contract value, excluding wilful misconduct and breach of financial due diligence obligations. For foreign partners with a Swiss presence, verify which court has jurisdiction (Art. 31 CPC) and any agreed forum selection (Art. 17 CPC), and whether enforceable assets are located in Switzerland.
Document due diligence in a dated internal memo: in case of dispute, it demonstrates that the company acted with the diligence of a prudent businessperson (Art. 321e CO for GmbH, Art. 717 CO for AG).
Accounting impact and exposure management
Pre-contractual decisions feed directly into the balance sheet and liquidity management. Here is how to translate them into accounting practice compliant with Swiss standards (CO / Swiss GAAP FER):
Advance payments and deposits: recorded as receivables or fixed assets in the balance sheet, depending on nature. Assess the need for a write-down if the partner shows signs of deterioration before delivery — prudence and going concern principle (Swiss GAAP FER 2 / Art. 960b CO).
Trade receivables from the partner: monitor ageing separately from end customers. Receivables over 90 days from a strategic partner require recoverability analysis and, where appropriate, provision for bad debts.
Guarantees issued: a guarantee in favour of the partner must be recorded as a contingent liability with disclosure in the notes, unless fees are certain. It affects bank covenants and your lender's risk perception.
Joint investments: fixed assets purchased for a specific partner (moulds, ERP configurations, dedicated warehouse) have a useful life tied to the contract. Plan consistent depreciation and buy-back or valuation clauses in case of early termination.
Accountex tip: create a strategic partner register with maximum exposure, date of last review, guarantee expiry dates and internal rating. Link each entry to the chart of accounts (advance payments, receivables, guarantees account) to see the impact on liquidity and net working capital in your dashboard.
Five-stage operational workflow
Standardise the process to prevent commercial pressure from bypassing controls:
- 1
Relationship qualification
The sales lead completes a form with three-year contract value, advance payments requested, strategic dependency and market alternatives. Management classifies the due diligence level (basic, in-depth, extended).
- 2
Public data collection and credit reports
Administration or accounting extracts Zefix data, checks SHAB and orders CRIF/Intrum reports. Results are archived in the partner file with timestamps.
- 3
Financial analysis and risk memo
The CFO or trustee calculates ratios, highlights red flags and formulates a recommendation: proceed, proceed with guarantees, renegotiate terms or decline. For extended level, involve an auditor or legal adviser.
- 4
Contract negotiation
Incorporate into the contract clauses consistent with the memo. No signature until bank guarantees or pledges are active, if provided as a condition precedent.
- 5
Ongoing monitoring
For high-exposure partners, repeat checks at least annually or upon covenant breach. Set up alerts for new SHAB entries and rating changes. Reassess exposure at contract renewal.
Informed decision-making: protected capital, sustainable partnership
Committing capital to a B2B partner without verifying solvency means accepting risk not priced into the contract. Swiss SMEs have accessible tools — commercial register, credit reports, accounts analysis — to make documented decisions in days, not weeks.
Financial due diligence is not a tool of distrust, but of alignment: solid partners accept proportionate guarantees and mutual transparency. When the numbers or warning signs do not add up, declining or renegotiating an agreement always costs less than recovering receivables in insolvency proceedings.
Integrate this process into corporate governance and record it in Accountex: exposure per partner, review deadlines and impact on liquidity become visible at the right time, before tied-up capital becomes a balance-sheet problem.
