• Matching parts to models and part numbers
• Basic website or online marketplace setup
• Customer service and returns handling

• Product liability insurance, and check any supplier or brand distribution terms

Startup costs are typically estimated at around $1,000 to $6,000, depending on whether you dropship or hold stock, and how you set up your website or marketplace listings. Costs rise if you stock your fastest-selling filters.

Monthly revenue is typically estimated at around $500 to $5,000, depending on your range, how well you match filters to models, and how much you spend on marketing. Treat this as an estimate, not a promise.

Check Australian Consumer Law obligations on refunds and warranties, when GST registration applies (ask the ATO), and product liability insurance. Also check any supplier or brand distribution terms, and state your returns policy clearly to reduce wrong-fit returns.
