How to track business expenses
Tracking expenses is how you find out what the business actually keeps. For solo sellers and small shops it's easy to let costs scatter across cards, apps, and platforms until no one knows the real number. Here's a simple system that keeps your costs clear and makes tax time painless.
1. Categorize every cost
Sort spending into clear buckets: cost of goods, platform and payment fees, ad spend, shipping, software, and supplies. Consistent categories turn a pile of charges into numbers you can actually read and compare month to month.
2. Keep every receipt
Save a copy of each receipt and invoice the moment you get it. A quick photo or a forwarded email is enough. The goal is a record you can find later, not a shoebox you dread opening when taxes are due.
3. Separate business from personal
Use a dedicated card or account for the business. Mixing personal and business spending is the fastest way to lose track of real costs and the slowest thing to untangle later. One clean line makes everything after it easier.
4. Log COGS, fees, ad spend, and shipping
These four are the costs that quietly eat profit. Record what each sale cost to fulfill, what the platform took, what you spent to win the order, and what shipping ran. Together they tell you what you really kept.
5. Review monthly and prep for tax time
Set aside a short review each month to reconcile charges and catch anything miscategorized. Doing it in small, regular passes means tax season is a quick export, not a frantic weekend of guesswork.
Why a system beats a shoebox
The point of tracking isn't paperwork, it's knowing your numbers. When costs are categorized and logged as they happen, you can see which products and channels actually make money, spot a fee creeping up, and hand your accountant a clean export instead of a guess. The same habit that keeps you organized is the one that shows you where profit is leaking.

Why should I separate business and personal spending?
Mixing the two makes it hard to see what the business actually costs to run, and it turns bookkeeping and tax prep into a sorting job. A dedicated card or account keeps every business charge in one place, so your expense totals are accurate without extra untangling.
Which business expenses are easiest to miss?
Usually the recurring and per-order ones: platform and payment fees, ad spend spread across channels, shipping, and software subscriptions. They are small individually but add up fast, and because they do not look like a single big purchase they often go uncounted.
How often should I track expenses?
Record costs as they happen and reconcile once a month. Logging in the moment keeps receipts from piling up, and a short monthly review catches miscategorized charges while they are still fresh. Small regular passes beat one big cleanup at year end.
Do I really need to keep receipts?
Yes. Receipts and invoices back up what you report and make tax time far smoother if a cost is ever questioned. A photo or a forwarded email is enough, as long as you can find it later. Save them as you go rather than reconstructing from memory.
