Physically handing over your goods to a third party means risking damage or loss of the items. This may happen in transit or during an accident on site at the fulfilment centre. The way to mitigate this risk is to do your due diligence on trustworthy 3PL companies and take note of customer reviews which mention such occurrences. Of course, many 3PL suppliers will offer inventory insurance policies, or you can take out one independently. If you send your goods to the supplier outside of individual packaging, you lose oversight of the final packaging process. Some 3PL companies are better than others at accommodating individual packaging requests, such as tissue paper, bespoke void filling, stickers and so on. You should quiz your sales rep or account manager on the specifics of the packaging policies of their 3PL.
