Proforma Invoice
Preliminary payment document used to initiate a transfer; not the final VAT/accounting invoice.
Definition
Preliminary payment document used to initiate a transfer; not the final VAT/accounting invoice. The preferred label in this knowledge base is Proforma Invoice. Related wording used in German or Polish is shown as Proforma (PL/DE: proforma invoice).
The article is written for practical investment use rather than academic completeness. It combines standard real-estate terminology with lessons from the P1 Gdańsk process, where location, legal verification, financing and operating model had to be judged together under time pressure.
Legal and administrative context
Polish property transactions often involve documents and identifiers that foreign buyers may not know from Switzerland or Western Europe. The P1 approach is simple: every identifier, company name, register extract, invoice and bank account should match across independent sources before money moves.
| Document / register | Purpose | P1 check |
|---|---|---|
| KRS / NIP / VAT | Company and tax identity | Names and numbers must match seller documents. |
| Księga wieczysta | Legal title and ownership | Property address and owner must match the deal. |
| Proforma / invoice | Payment instruction | Bank account and gross/net/VAT logic must be clear. |
| Notary confirmation | Transaction workflow | Neutral confirmation reduces process risk. |
Relevance to P1
Piotr’s company-sale flow used a proforma invoice before the notarial deed. This felt unusual from a Swiss perspective, but the notary confirmed that the flow can be normal for a company seller when followed by an advance invoice and full documentation.
Practical checklist
- Verify names and numbers independently.
- Ask the notary or local expert about unfamiliar procedures.
- Check whether the document affects payment or ownership.
- Keep a dated copy in the document file.
- Translate only after preserving the original wording.
Common mistakes
Typical investor mistakes
- Trusting screenshots without rechecking official registers.
- Missing a mismatch between company, account and invoice.
- Assuming familiar Swiss procedures apply unchanged.
- Failing to ask the notary the direct process question.
When to be conservative
Be conservative whenever the term affects a payment decision, a legal assumption, the first-year cash-flow forecast or the ability to exit the investment. Optimism is allowed in the upside scenario, but the base case should remain operationally boring.
Decision lens
| Question | Why it matters |
|---|---|
| Does it change the go/no-go decision? | Important terms should affect action. |
| Can it be verified? | Verifiability separates data from opinion. |
| Does it affect cash flow? | Operating reality matters more than theory. |
