Supplier Due Diligence in a Crisis: Is Your Supply Chain Still Standing?

When the economy turns, your supply chain becomes a list of open questions. Is the factory still running? Is the distributor still solvent? Is the new partner who appeared last month really who they say they are?

These questions are easy to postpone when orders are flowing. In a crisis, they decide whether your business keeps delivering or gets caught in someone else's collapse.

This article explains how supplier due diligence helps you protect your business in crisis times. It is written for procurement leads, CFOs and owners who need clarity about the companies they depend on.

A crisis changes your partners before it changes your contracts

Your contracts stay the same during a downturn. The companies behind them do not.

A supplier under pressure may cut corners on quality. It may sell the business quietly. It may move production to a subcontractor you have never heard of. A distributor may keep ordering goods it can no longer pay for.

None of this is necessarily dishonest. Companies in trouble often try to survive by improvising. The risk for you is that you find out too late.

Composite illustration; not a single client case: A Swiss machinery firm relied on one component supplier in Eastern Europe for eight years. During a slow quarter, deliveries began arriving from a different address. The paperwork still showed the familiar name. A quiet check showed that the original company had been sold and the new owner had no track record in precision parts. The firm used that information to arrange a second source before the next batch failed inspection.

There was no scandal in that story. There was simply a change that nobody had noticed.

Red flags that deserve a closer look

You do not need to investigate every supplier. You need to notice when something shifts. These signs justify a second look:

New bank details, especially in a different country from the supplier's base.
A sudden change of directors, owners or registered address.
Pressure for prepayment that did not exist before.
Delivery addresses or subcontractors that change without explanation.
Unusually low prices from a new supplier with a short history.
Contacts who stop answering the phone and only reply by email.

One sign on its own may be harmless. Two or three together form a pattern worth checking.

What supplier due diligence actually verifies

Supplier due diligence is a structured check of the companies you buy from, sell through or partner with. It answers practical questions before you commit more money or goods.

Depending on the agreed scope, we typically look at:

Identity and existence: Is the company registered where it claims to be, and does it operate from a real site?
Ownership and control: Who owns the company today, and has that changed recently?
Management history: What other companies have the directors run, and how did those companies end?
Litigation and enforcement: Are there lawsuits, debt enforcement records or regulatory matters where lawfully accessible?
Reputation: What do public and industry sources say, and are there consistent concerns?
On-site verification: Where appropriate and authorized, does the factory or warehouse actually exist and operate as described?

Each finding is reported with its source and its level of confidence. A claim, a corroborated fact and an unresolved question are clearly separated. You can read more about the service on our due diligence investigation page.

New partners need more scrutiny, not less

Crisis periods bring offers. A buyer for surplus stock. A distributor in a new market. A financier who can bridge the gap.

Some of these are genuine lifelines. Some are opportunists who target companies under pressure, because pressure makes people sign faster.

The contrast is simple:

Signed on trust: you learn who your partner really is when the first problem appears.
Signed after a check: you know who you are dealing with, and you negotiate with that knowledge.

A short check before signing rarely delays a good deal. It often prevents a bad one.

A practical routine for procurement teams

You can build supplier due diligence into normal work without creating a bureaucracy. Here is a simple routine that works well in difficult periods:

Rank your suppliers by how much damage a sudden failure would cause.
For the top group, review public information on ownership and management every six months.
Confirm every change of bank details through a known phone number.
Ask for current documents when a supplier changes address, owner or production site.
Commission a deeper check before any new contract above an agreed value.

This routine costs little. It turns vague worry into a manageable list.

Customers are suppliers of cash

Due diligence is not only about who you buy from. In a downturn, the companies that buy from you matter just as much. A distributor that keeps ordering while paying later and later is, in effect, borrowing from you.

Apply the same logic to your largest customers. Look for changes in ownership, new directors, sudden moves to a different bank and growing payment delays. When several of these appear together, consider shorter payment terms, a deposit or a smaller credit limit until you have a clearer picture.

This is not about distrust. It is about matching your exposure to what you actually know.

Questions to ask before your next order

Take a moment with these questions:

Which of your critical suppliers has changed owner, address or bank in the past year?
How would you know if a key partner were quietly preparing to close?
What would a two-month delivery gap cost your own customers?
Would knowing the answer before the next large order give you more control?

Frequently asked questions

What is supplier due diligence?

It is a structured verification of a supplier's identity, ownership, management, legal history and reputation. It helps you decide whether to start, continue or change a business relationship.

How often should we check our suppliers?

Critical suppliers deserve a light review at least twice a year and a deeper check whenever something important changes. In a downturn, more frequent reviews are sensible.

Can you verify suppliers outside Switzerland?

Yes. We work internationally. The depth of available information differs from country to country, and we explain those limits before work begins.

Is supplier due diligence the same as a credit check?

No. A credit check looks at payment behavior. Due diligence also looks at who controls the company, how its managers have performed before and whether it operates as it claims.

Clarity is the best protection

A crisis tests every relationship your business depends on. Some partners will prove stronger than expected. Others will need a plan B. Knowing which is which, early and quietly, gives you room to act calmly.

If a supplier or partner has started to raise questions, a confidential conversation can help you decide what to check first.
