Business Expense Categorizer

Paste a messy list of business expenses and get a tidy, copyable table of suggested plain-language categories — with the uncertain ones flagged instead of guessed.

One expense per line. Amounts are optional. This is an organizational aid, not tax advice: it will not tell you whether something is deductible, and anything that depends on how you actually use the item is flagged for your review.

Your expenses

Paste straight from a bank statement export or type them out.

Context helps: a camera is a very different line item for a photographer.

Add at least one expense line.

Suggested categories

Paste your expenses and a categorized table will appear here.

Your input is sent to an AI model to generate the result and isn't saved to your profile. Leave out client names, contracts, and anything confidential.

Why expense categorizing eats a whole afternoon

The bookkeeping itself is not hard. What takes the time is the decision on every single line: is this software or advertising? Is a laptop stand office supplies or equipment? Was that card charge a client lunch or lunch? Doing that a few hundred times is why receipts pile up until the end of the quarter.

Sorting expenses into consistent buckets is an organizational job, not a legal one. The goal is a record where you can see where money actually went, and where a professional can pick it up without having to re-derive every line.

What this tool does — and does not — do

  • It suggests a plain-language category for each item you paste
  • It gives one short sentence of reasoning so you can disagree with it
  • It flags items whose category depends on facts only you know
  • It does not say anything about deductibility, tax treatment or what you can claim
  • It does not present its categories as official or authoritative — bookkeeping conventions differ between accountants, software and jurisdictions

Categories that cover most solo businesses

Software and subscriptions; advertising and marketing; contractors and freelancers; office supplies; equipment and hardware; travel; meals; vehicle and mileage; rent and workspace; utilities and internet; phone; professional services; insurance; bank and payment fees; education and training; shipping and postage; inventory and materials. A short list you apply consistently beats a long one you apply differently every month.

The items that need a human

Anything with a personal side — a phone, home internet, a car, a laptop used in the evenings — and anything where the description alone does not tell you what was bought. Those come back flagged rather than filed, because a confidently wrong category is worse than an open question. Where the answer depends on your jurisdiction or on how much you use something for the business, that is a conversation for your accountant.

Keeping the books lighter

Categorize weekly rather than quarterly, use one card for business spending, and write a two-word note on anything unusual at the time. On the income side, the invoice reminder email generator handles the awkward part of getting paid, and the client onboarding email generator sets expectations before a project starts. The rest of the free tools cover the other admin jobs.

Questions

What are common small business expense categories?
Most one-person businesses get by with a short list: software and subscriptions, advertising and marketing, contractors, office supplies, equipment, travel, meals, vehicle costs, workspace, utilities and internet, phone, professional services, insurance, bank and payment fees, training, shipping, and materials or inventory.
Is this tax advice?
No. This tool helps you organize records into plain-language buckets. It does not say whether anything is deductible, claimable or reportable, and it is not a substitute for an accountant or a tax professional in your own country.
Why are some rows flagged for review?
Because the right category depends on facts only you know — whether an item is used personally as well as for the business, what a vague line item on a statement actually was, or how your bookkeeping and local rules treat it. Guessing those would make your records less reliable, not more.
How should I handle expenses that are part personal?
Keep them in their own bucket while you work out the split, and record how you arrived at the proportion. Mixed-use items are the ones most worth raising with an accountant, because the treatment varies by jurisdiction and by how you actually use the item.
Can I paste rows straight from my bank statement?
Yes. One expense per line, up to 60 lines per run. Amounts are optional and are ignored when suggesting a category. If a line is just a payment processor descriptor with no clue what was bought, expect it to come back flagged for review.
