I just started working in this industryI've sent a Proforma Invoice to the client. Do I need to stamp the PI? Will not stamping it affect the order execution or customs clearance?

From the perspective of compliance and risk control，I suggest that your PI (Proforma Invoice) should be stamped with an official seal. Although a PI is not an official commercial invoice，it carries an offer-based nature，and its legal validity will be strengthened after stamping. Especially when clearing customs in some countries in the Middle East，South America，and Africa，customs may require a stamped PI as proof of the value of the goods. The main risks of not stamping the PI include。
1. Clients may question your professionalism。
2. In the event of trade disputes，the evidentiary value of unsigned documents will be weaker。
For new clients，large orders，or letter of credit payments，stamping is an essential risk management measure. Although electronic signatures are gradually gaining acceptance，traditional official seals remain the preferred choice in most emerging markets.

From a logistics operational perspective, a stamped PI can streamline your customs clearance process. Many countries' freight forwarders and customs brokers require stamped PIs as filing documents, especially when applying for a FORM A certificate of origin or authenticating commercial invoices, as the customs system needs to match the information on the stamped PI. My practical advice is as follows:
1) Always provide clients with stamped PI scans, while retaining the Word version for easy modification;
2) If the client is a regular customer with urgent orders, you can initially send unstamped versions for confirmation, but the stamped version must be used for official customs declarations;
3) For air freight or express small packages, stamping requirements are relatively relaxed, but for ocean freight full containers, strict stamping is recommended. Remember, a stamped PI is a standard component of customs clearance documents—it’s better to be prepared than to face potential issues later.

From the perspective of business negotiations, stamping is a small detail that builds trust, but it has a significant impact on securing orders. My strategy is: for new clients, the PI must be stamped, which sends a signal that "we are a legitimate company"; for long-term clients who have cooperated for more than three years, if the client explicitly says "don't stamp it, just send it quickly," you can handle it flexibly. However, there's a trick: you can add a small line at the bottom of the PI, "This quotation is valid for 30 days and will take effect after our stamping," which not only appears professional but also retains your initiative. Nowadays, many European and American clients accept electronic signatures, so you can use Adobe Sign or DocuSign. But remember to write "Please find the digitally signed PI attached" in the email body to actively clarify and avoid client doubts. In short, stamping is a zero-cost, high-return investment in trust.
