How can manufacturers fix stock visibility and fulfillment delays on Amazon seller accounts?

Stock visibility and fulfillment delays on Amazon are a widespread issue affecting multiple sellers. Members report stock taking weeks or months to appear on seller pages, and experiencing significant losses to logistics partners (one member cited £2.5k in unaccounted stock via UPS).

**Key recommendation:** - **Change your delivery/logistics supplier** — One member reported major improvements after switching away from their existing delivery partner. This suggests the delay may be at the carrier/fulfillment stage rather than Amazon's system itself. Members recommend reaching out directly to others who have solved this (contact via DM for specific supplier recommendations).

**Caveat:** Members acknowledge this is a widespread frustration affecting "everyone" on the platform, suggesting systemic challenges with Amazon's fulfillment network that may not have a universal fix. Stock loss to carriers during transit is a real risk factor.
