Booth staff apparel
Apparel needs the supplier invoice, evidence of VAT status, and the delivery record showing quantity by size, because the size breakdown is the only thing that will later prove the delivered quantity matches the purchased quantity. Where blanks are imported rather than produced domestically, add the import evidence: the customs declaration reference, the importer of record, and the country of origin of the garment itself as distinct from the decoration. If items are provided to employees rather than worn only at events, confirm the intended tax treatment with your accountant before ordering, because the treatment can differ from an event-only distribution.
