# How to Keep Track of Business Expenses Without a Shoebox of Receipts > A simple way to track business expenses: capture each receipt when you pay, keep business spending separate, reconcile weekly and file expense reports on time. Source: https://www.getmindie.app/blog/track-business-expenses (published 2026-10-29) It's the end of the quarter. There's a coffee-stained receipt in your coat pocket, three in the car and a parking charge you only remember because it's on your card statement. You know there were more. You just can't prove them. Tracking expenses gets easy once capture happens at the moment you pay, not weeks later from memory. ## Why expenses go missing The expenses that go missing are usually the small ones: a taxi, a train ticket, a client lunch, a software add-on. Each feels too small to bother with at the time, and together they add up to a lot over a year. They go missing for a few reasons: - **The receipt is paper,** and paper gets lost, faded or thrown away. - **Personal and business spending are mixed** on one card, so you have to work out which was which later. - **Nobody sits down to sort them** until a deadline forces it. - **There's no record of why,** so even when you find the receipt, you can't remember who the lunch was with. ## Step 1: Separate business from personal If you do one thing, do this. Use a separate bank account and card for business spending, even if you're a sole trader or a freelancer. Then your business statement is already most of your expense record, and you're not hunting through supermarket shops for the one client lunch. If a separate account isn't possible yet, pick one card that's only used for business and keep it that way. ## Step 2: Capture at the moment you pay The best time to record an expense is within a minute of paying for it. A simple routine: 1. **Photograph the receipt** before you put it away. Make sure the total, date and vendor are readable. 2. **Add a line of context:** what it was for and, for meals or travel, who it was with or which client it relates to. 3. **Put the photo somewhere you'll find it,** like an expenses folder in your phone's gallery or your accounting app. Context is the part people skip, and it's the part that matters most when an accountant or a finance team asks questions. "Lunch, $48, with Tom from Harper & Co about the spring project" answers every question in advance. ### Mileage and travel If you drive for work, log each trip as you finish it: date, from, to, miles and the reason. Trying to rebuild a mileage log from your calendar at year-end is slow and unreliable. ## Step 3: Use simple categories You don't need dozens. Most small businesses and freelancers get by with a short list, for example: - Travel and transport - Meals and entertainment - Software and subscriptions - Equipment - Office and supplies - Professional fees - Marketing Ask your accountant which categories matter for your taxes, and which expenses are allowable where you are. That's their call, not your reminder app's. ## Step 4: A weekly ten-minute reconcile Capture catches most expenses. A weekly check catches the rest. Once a week, open your business account and go through the last seven days: 1. Does every payment have a receipt and a line of context? 2. Anything missing? Find the receipt in your email or request a copy now, while it's still easy. 3. Any personal spending on the business card? Note it so it can be moved or paid back. 4. Any subscription you don't recognise or no longer use? Cancel it. Ten minutes on a Friday afternoon beats a lost weekend in April. If you already do a weekly review, add this as one step. The [weekly review guide](/blog/weekly-review) shows how. ## Step 5: File expense reports on time If you're employed and claim expenses back, the deadline is usually set by your company, often monthly. Late reports can mean waiting another month to get your money back, or losing the claim altogether. Set a reminder a few days before the cutoff, not on it, and keep a running list of what you need to claim during the month. On the day, you're only putting together what's already there. ## How to run this with Mindie Mindie lives in WhatsApp, which is already open on your phone when you're standing at the counter. It doesn't replace accounting software or store your receipts for tax purposes. What it does is make sure you capture the context and do the weekly and monthly steps. Right after paying, send a note: - "Add to March expenses: taxi to airport, $36, client trip for Harper & Co" - "Add to March expenses: lunch with Mia from Brightline, $52" Ask "what's on my March expenses list?" when you sit down to do the report. Set the routines once: - "Every Friday at 4pm remind me to reconcile the business account" - "Every month on the 25th at 10am remind me to submit my expense report" When the report's in, reply "done". If Friday gets busy, "snooze 1 hour" moves it on without losing it.

Use a separate account or card for business spending, photograph each receipt when you pay with a line about what it was for, and check your business account once a week for anything missing. ### How long should I keep business receipts? It depends on where you live and your business type, and tax authorities often expect several years. Ask your accountant or check your tax authority's guidance, and keep digital copies so faded paper receipts aren't a problem. ### Do I need to keep receipts for small expenses? Generally yes, if you want to claim them. Small expenses add up over a year, and a receipt with a short note of the purpose is the simplest proof. Your accountant can tell you what records your tax authority accepts.
