# Cross-border: split goods invoice from callout travel/B&B Namibia/Imberbe customs will stop the truck when invoice lines mix goods with technician flight / B&B accommodation (example invoice 10206527 / MM4255-KIMJUL-19). Fix: goods-only revised invoice + clarification letter (and/or separate service invoice). Require COO, Exporters Code, Namibian clearing instruction before cross-border ship.
