About Stewin

I help SMEs and entrepreneurs buy better from outside Spain: I find, verify, and compare international suppliers, and calculate the real cost of your product delivered to your warehouse, including freight, duties, and VAT, so there are no surprises at customs.

I am a specialist in purchasing and international trade, with over 4 years of experience in purchasing departments of companies in the industrial/energy and food ingredients sectors. In my daily work, I manage suppliers from Europe, Asia, and America, negotiate prices and terms, oversee more than 300 references, and handle all import documentation: Incoterms, tariff codes (HS/TARIC), Bills of Lading, and customs clearance. I regularly work with SAP, Business Central, and Salesforce.
What can I help you with?

International sourcing: search and pre-selection of manufacturers and suppliers for your product, with verification of company age, certifications, and export experience.
Quotation comparison (RFQ): sending professional requests and comparative analysis so you can choose based on data, not intuition.
Import cost calculation (landed cost): final price per unit delivered in Spain, with itemized duties and taxes.
Supplier negotiation: payment terms, MOQ, delivery times, and trial orders.
Guidance for your first import, from sample to order.

My most common format is the Sourcing Report: in 7-10 days, you receive 3 verified and compared suppliers, with a justified recommendation and calculated import cost. Fixed price, no inflated hours.
Bilingual Spanish-English: I negotiate directly with international suppliers without intermediaries.
If you are considering importing a product or want to reduce the cost of your current purchases, write to me and we'll discuss it without obligation.
