Payment Flow & Proforma

Due Diligence·Updated 27 Jun 2026·10 min·Confidence: High

Understanding the Polish company-seller flow: proforma, transfer, zaliczkowa invoice and notarial deed.

Payment Proforma VAT PL: faktura zaliczkowa

Observed flow

Piotr described: proforma invoice → PLN transfer to company account → 100% advance invoice (PL: faktura zaliczkowa) → notary → final invoice.

Key takeaway. This section is designed as an operational reference, not a motivational note. Every claim should eventually map to a document, observation or calculation.

Why it felt sensitive

Paying before ownership transfer feels unusual from a Swiss perspective. The correct response was not blind trust, but independent notary confirmation.

Notary signal

The notary office confirmed that the proforma-to-payment flow can be normal in this case, while an escrow/Notaranderkonto can also exist as a different structure.

Control points

The bank account must match official VAT/white-list evidence, the company name must match the land register and the notary must know the case before payment.
