Meet Warehouse Collectible: a Part-Time Reseller on Amazon FBA and eBay

For years, Nicholas has enjoyed thrifting and reselling his finds, so he set up Warehouse Collectible on Amazon and eBay to share those finds with like-minded individuals.

From reselling toys and software kits to YouTube video recording and editing gear and much more, Warehouse Collectible has become a one-stop platform for toys and software.

However, as Nicholas started selling more, his taxes as a self-employed individual grew proportionately. It was time to explore ways of reducing his tax and National Insurance Contribution (NIC) liabilities.
