Today
A one-off check
- An activity certificate is asked for at onboarding, never refreshed
- A name change is noticed in an invoice mismatch
- A concordat notice comes to light only when deliveries stall
- The signatory’s authority is never checked
Solution · Corporate procurement
Is your supplier still the same company?
At onboarding verify the supplier’s name, registry, address, officer and status with sources; during the contract learn the same day about concordat, bankruptcy, liquidation, name and address changes.
- Sourced verification at onboarding
- Monitoring for the contract term
- API for ERP and portal
Today and with Ulawk
A supplier file freezes on onboarding day.
A supplier is verified once and then used with the same record for years. Meanwhile name, address, management and status change.
With Ulawk
Continuous and sourced
- Name, registry, address, officer and status with sources at onboarding
- Name and address changes the same day
- Concordat, bankruptcy, liquidation with a red alert
- Signing authority and internal directive limits in the profile
Supplier record
Don’t make them fill in forms, verify.
Compare what the supplier declares with what the register says; each row tied to its notice.

Compare with the declaration
Are the name and address on the supplier’s form the same as in the register? At a glance.
Status
“Active” is an inference because no adverse notice was seen; the screen says so.
Supplier checklist
Seven checks, one profile.
Checks made at onboarding repeat on their own for the length of the contract.
| Check | In Ulawk | Refreshed |
|---|---|---|
| Does the company exist, is it active? | Three-layer status | With every new notice |
| Do name and address match? | Identity, name and address history | With every new notice |
| Is the signatory authorised? | Management and representation, internal directive | With every new notice |
| Any sign of financial distress? | Concordat, bankruptcy, liquidation, capital loss | With every new notice |
| On a sanctions list? | Company, officers and shareholders; exact names | Lists daily |
| Whose company is it? | Shareholders and beneficial owner candidates | With every new notice |
| Links to other suppliers? | Relationship network: shared officer, same address | With every new notice |

At every stop the same profile is consulted; at every stop it is current.

Contract
The signatory’s title and form of representation; internal directive limits.
During the contract
Status, name, address and management changes the same day.

ERP and supplier portal
A new supplier, monitored automatically.
When onboarding completes in your supplier portal, add the company to monitoring via the API; write changes back to ERP with webhooks.

How many suppliers can I follow?
Plans differ by the number of companies followed; every feature is in every plan. For long lists, an enterprise plan and a quote.
Can I add suppliers in bulk?
Yes. From Excel with registry office, registry number and name columns, or via the API. A company whose registry number you do not know can be added by name and picked from candidates.
What happens if a supplier files for concordat?
The day the notice is published it arrives at the top of your e-mail with a red alert; with a webhook it also reaches your ERP.
Are suppliers abroad supported?
Yes. Add them by the country’s company number or by LEI. Which data comes back in which country is in the coverage table.
Do you show tax debt or a credit score?
No. Ulawk shows official registry records; it contains no tax, social security or payment performance data.
