Try one shipment. No signup.
Change five numbers, then make a matching Invoice and Packing List. Use fictional numbers only.
Your fictional shipment
Sample Export Co. → Sample Import Co.
100% sample data · Cotton T-shirt · USD · PCS
Only the numbers are sent to generate these fictional PDFs. They are not saved as documents, and no workspace allowance is used. Anonymous activity counts are recorded, without document contents.
Your two sample PDFs are ready.
Compare the buyer, item and quantity across both PDFs. Check the invoice value, cartons and weights against your entries.
Practice documents only, not for an actual shipment. No customs filing or compliance certification. In the saved workspace, cartons and weights are entered manually and Invoice edits do not update an existing Packing List.
Would this fit the documents you prepare?
Workspace: five saved documents per month, Invoice and Packing List counted separately. Paid checkout is off. Practice values are not transferred to signup.
