Frequently Asked Questions

What is a good inventory turnover ratio for a small e-commerce business?

For small e-commerce businesses, a turnover ratio between 6-8 is generally healthy. However, this varies by industry – fashion typically sees lower ratios (4-6) while electronics should aim higher (8-10). The key is consistent improvement rather than hitting a specific number.

How much does poor inventory management cost the average business?

Studies show businesses lose 20-25% of potential revenue due to poor inventory practices – including stockouts, overstock carrying costs, and administrative inefficiencies. For a $1M business, this represents $200,000-$250,000 in lost opportunity annually.

What's the difference between inventory accuracy and inventory turnover?

Inventory accuracy measures how well your records match physical stock (ideally 95%+). Turnover measures how quickly you sell through inventory (higher is generally better). You need good accuracy to accurately measure turnover and make sound purchasing decisions.

How can small businesses improve inventory management without expensive software?

Start with regular cycle counts, ABC analysis (focus on high-value items), and clear procedures. Platforms like Mewayz offer free tiers specifically for SMBs. The key is consistency – even simple systems work well when followed rigorously.

What inventory metrics should I track most closely?

Focus on these 5 key metrics: 1) Inventory turnover ratio, 2) Days of inventory on hand, 3) Stockout rate, 4) Carrying cost percentage, and 5) Order accuracy rate. Tracking these consistently provides the clearest picture of inventory health.
