A highly profitable, five-year-old Amazon business specializing in custom vinyl car decals is generating impressive financial returns with a trailing 12-month revenue of $193,566 and Seller's Discretionary Earnings (SDE) of $111,465, equating to a ~57.5% net margin. This streamlined, home-based operation is characterized by zero inventory risk due to its Just-In-Time (JIT) production model. The business is managed by a single owner-operator, requiring minimal commercial space. Key operational highlights include tens of thousands of active listings facilitated by automated tools, and a condensed production schedule fitted into about 30-40 hours per week. A significant Amazon presence ensures stable organic traffic, with an excellent account health rating. Notable assets included in the sale are a registered trademark, a proprietary design library, and some ready-to-ship inventory. The operational routine is organized around efficient production days (three days per week), comprising tasks from admin management to batch production and dispatch. Weekly operations focus on supply reordering and top-SKU replenishment, while monthly financial archiving ensures streamlined bookkeeping. Financially, the operation maintains low overheads with expenses like Amazon fees, shipping, and material costs comprising a small percentage of revenue. There is significant scope for growth through catalog expansion, channel diversification (Etsy/Shopify), introduction of Amazon PPC, and scaling through FBA. The owner offers transition support and is willing to fine-tune the design catalog for risk management. The business presents an attractive opportunity for buyers seeking a tested, scalable model with a strong foundation in the vinyl decal market.
