While parts and accessories sales are one of the most profitable revenue streams for your dealership (along with fixed ops), it’s a highly competitive market, especially online. Online part sales are a multi-billion dollar business ($12 billion in 2019, ~$16 billion in 2020), largely dominated by retail giants like Amazon and eBay, along with major aftermarket parts retailers (Auto Zone, O’Reilly, Advanced Auto Parts, etc.)
According to Hedges & Company, in 2019, Amazon sold $8 billion in parts ($5.3 billion 1st party sales), accounting for 2/3 of all online parts sales in the US. And as of the latest study, they were on track to pass $10 billion in 2020. These numbers may be intimidating, but there is still room for your dealership to have a successful online parts business.
