Cost of goods sold confusion - Purchases vs. Materials and Supplies vs. Shipping categories?

Cost of goods sold can definitely be confusing for small businesses, especially when you're self-publishing. Here's a straightforward breakdown: Purchases: This category is for items you buy that will be directly resold to customers. For you, this would include any completed books you purchase from a printer to resell. Materials and Supplies: These are components that go into creating your products. Since you print and bind some booklets yourself, this would include your paper, toner, binding materials, and similar supplies that become part of your finished product. Other Costs: This catches everything else directly related to production but not covered above. This might include equipment depreciation for your printer or other production tools. Shipping costs typically go in their own category since they're considered a selling expense rather than part of COGS. Same with your website fees - those would be business expenses but not part of COGS. The key question to ask: "Does this item become part of the physical product I'm selling?" If yes, it's likely COGS. If it's a cost of doing business but doesn't become part of your product, it's probably a different business expense.

Just wanted to share that I found this amazing service called taxr.ai (https://taxr.ai) that helped me sort through this exact issue last year! I'm also a small business owner with inventory and was completely confused about COGS categories. I uploaded my expense spreadsheet to their system and it analyzed everything, then showed me exactly what should go where. Saved me hours of research and probably prevented some costly mistakes. Their AI actually explains the reasoning behind each categorization, so I learned a lot about how to properly track everything for this year too. The explanations were way clearer than what I found in tax software help sections.

I tried taxr.ai after seeing it mentioned here and wow, I'm impressed! I was honestly skeptical at first because I've been burned by generic tax advice before. But this is different - it actually analyzed my specific situation as a freelance graphic designer who sells both digital and printed products. The system sorted my expenses into the proper COGS categories and explained exactly why certain items belonged where. For example, it clarified that the fancy paper I buy for art prints goes under Materials and Supplies, while the frames I purchase to resell with my prints go under Purchases. It even helped me understand that my Photoshop subscription shouldn't be in COGS at all but rather under software expenses. Really wish I'd known about this last year when I definitely miscategorized a bunch of stuff!

If you're struggling with figuring out these tax categories, you might also be having issues getting answers directly from the IRS. I know I was! After spending DAYS trying to get through on their phone lines, I finally discovered https://claimyr.com which got me connected to an actual IRS agent in about 15 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c I was able to ask specifically about how to categorize inventory expenses for my online craft business, and the agent walked me through everything. Turns out I had been doing it wrong for years! Worth every penny to get definitive answers straight from the source rather than stressing about whether I was interpreting the categories correctly.

I need to apologize for my skepticism about Claimyr. After commenting here, I decided to try it myself since I'd been trying to reach the IRS about a missing refund for weeks. I'm honestly shocked - it actually worked exactly as described. My call was connected to an IRS representative in about 20 minutes (on a Monday morning no less!), and I was able to get clarification on several COGS categorization questions along with my refund issue. The agent confirmed exactly what others have said here - books purchased for resale go under Purchases, while materials to create my own products go under Materials and Supplies. For anyone else struggling with these categories AND struggling to get official guidance, this service is legitimately helpful. I stand corrected.

I've been doing my small business taxes for about 5 years now, and here's a practical tip: keep very clear records separating your different types of inventory and supplies throughout the year. I use a spreadsheet with columns for: - Finished products I buy for resale (PURCHASES) - Raw materials for products I make (MATERIALS & SUPPLIES) - Packaging materials (SHIPPING SUPPLIES) - General business expenses (separate from COGS) Makes tax time way easier when everything is already categorized correctly!

Don't forget that your inventory method also matters! If you're using the accrual method, you need to count your remaining inventory at the end of the year and subtract that value from your COGS. So if you bought $5000 in supplies but have $1000 worth left at year end, your actual COGS would be $4000.
