A receipt stays in your wallet. An invoice remains buried in your inbox. A software renewal hits your card. You buy something for the business using your personal account and tell yourself you will record it later. none of these things feels urgent on its own. But leave them for a few weeks - or a few months - and a small bookkeeping task turns into an unpleasant backlog of bank transactions, missing receipts and expenses you can barely remember. When you run a business on your own, there is no one else waiting to clean it up. The solution is not necessarily more software or a more complicated bookkeeping system. It can be much simpler: **Spend 15 minutes once a week keeping your expenses up to date.** At SIMEFF, we recommend making it part of your Friday shut down routine. --- ## What is the 15-Minute Weekly Expense Routine? The 15-Minute Weekly Expense Routine is a short weekly process for checking your business transactions, recording missing expenses, categorising spending, organising receipts and flagging anything that needs attention. The routine follows five simple steps: 1. **Review** 2. **Record** 3. **Categorise** 4. **Match** 5. **Check** You are not doing a full financial review. You are simply preventing small pieces of financial admin from accumulating into a much bigger daunting job. --- ## The 15-Minute Routine at a Glance | Time | What to do | | ------------- | ------------------------------ | | Minutes 1–3 | Review the week's transactions | | Minutes 4–6 | Record missing expenses | | Minutes 7–9 | Categorise spending | | Minutes 10–12 | Match and store receipts | | Minutes 13–14 | Check anything unusual | | Minute 15 | Close the week | That's the whole routine. Once the system is established, your job is simply to repeat it. --- ## Why Do It Every Week? The biggest advantage of the weekly expense tracking exercise is that the transactions are still recent. If you see a $47 payment from three days ago, you will probably remember what it was. If you see the same transaction four months later, you may not. Weekly maintenance also prevents: - receipts from accumulating - forgotten expenses - uncategorised transactions - unidentified payments - months of catch-up work - unnecessary tax-time stress Five or ten recent transactions are usually much easier to deal with than hundreds of old ones. The point is not to spend more time bookkeeping. It is to spend a **small amount of time before the work becomes dauntingly difficult.** --- ## Why Friday? There is nothing magical about Friday from an accounting perspective. You could choose any day that works for you. Friday is useful because it creates a natural end-of-week checkpoint. The week's purchases are still fresh in your mind, and you can finish knowing: **This week's expenses are dealt with.** That small sense of closure can be surprisingly useful. It can also fit neatly into your Friday shutdown routine alongside tasks such as clearing your inbox, reviewing outstanding work or planning the following week. If Friday is one of your busiest days, choose another. **The best weekly expense routine is the one you will actually follow.** --- ## Set Up the System Once Before Your First Friday ## Before Your First Friday: Set Up the System Once The 15-minute routine works best when your expense system is already simple. You only need to make a few decisions. ### 1) Decide Where You Will Track Expenses Choose one primary place. It might be: - a spreadsheet - bookkeeping software - accounting software - an expense-tracking application For a straightforward one-person business with relatively few transactions, a spreadsheet may be enough. As transaction volume an financial complexity increase, accounting software can become more useful. The important thing is to avoid maintaining several competing records. **Give your expenses one home.** --- ### 2) Decide Where Receipts Will Go Receipts become difficult to manage when they can be anywhere. - Your email. - Your downloads folder. - Your phone photos. - Your drawer. - Your wallet. - Your car. Choose one main storage system. Create a folder for **`Business Receipts`**. Inside that folder, create a folder for the year **`2026`**, and then create 12 monthly sub-folders using numbers for automatic sorting. For example: **`Business Receipts`** - **`2026`** - `01_Jan` - `02_Feb` - `03_Mar` - `04_Apr` - `05_May` - `06_Jun` - `07_Jul` - `08_Aug` - `09_Sep` - `10_Sep` - `11_Nov` - `12_Dec` ![](https://storage.ghost.io/c/07/b0/07b05c56-0c23-436f-8f33-5c7d1cc1ecde/content/images/2026/09/Business-Receipts-Folder-Structure.jpg) Business Receipts Folder Structure You might use Google Drive, Dropbox, OneDrive or something similar. The specific tool matters less than have one predictable location. When you later ask: **Where is that receipt?** There should be an obvious answer. --- ### 3) Keep Your Expense Categories Broad You do not need dozens of categories. A simple one-person business might use: - Advertising & marketing - Software & Subscriptions - Office Expenses - Equipment - Website & Hospital - Travel - Professional Services - Contractors - Insurance - Phone & Internet - Education & Training - Banking & Payment Fees - Other Business Expenses Your categories should reflect your business and any accounting or tax requirements that apply to you. For day-to-day tracking, however, avoid unnecessary complexity. If you regularly spend several minutes deciding which category something belongs in, your categories may already be too detailed. --- ### 4) Put the Routine in Your Calendar Create a recurring appointment: **Friday - Weekly Expense Review - 15 Minutes** Choose a realistic time. For example: **4:45 PM - 5:00 PM.** Add this checklist to the calendar entry: - Review - Record - Categories - Match receipts - Check unusual items Now you do not have to remember what to do. You simply follow the routine. --- ## The 15-Minute Friday Expense Routine Now let's go through the process. Now let's go through the process. --- ### Minutes 1-3: Review This Week's Transactions Open your business bank account, business card or relevant payment accounts. Look through the transactions from the past seven days. Ask: - Do I recognise every transaction? - Which ones are business expenses? - Is anything unexpected? - Did I pay for anything using a personal card? - Did I pay for anything in cash? You are not trying to analyse the business yet. You are simply establishing what happened. You might see (for example): - software subscription - $29 - online advertising - $120 - printer supplies - $18 - web hosting - $15 - contractor payment - $250 If everything is immediately recognisable, move on. If something is not, flag it while it is still recent. --- ### Minutes 4-6: Record Anything Missing Compare those transactions with your expense tracker. If your accounting software imports transactions automatically, check that the relevant items have appeared correctly. If you use a spreadsheet, enter anything that is missing. At minimum, record: - date | Date | Supplier | Description | Category | Amount | | ------- | ---------------- | ------------------------------------------ | ----------------- | ------ | | 5-March | Google Ads | Paid Google Ads for April | Digital Marketing | $120 | | 5-March | Meta Ads | Paid Meta Ads for April | Digital Marketing | $120 | | 7-March | Square Space | abc.com Annual Domain registration renewal | Domain Renewal | $18 | | 8-March | Google Workspace | Annual Email Subscription Renwal | Email | $120 | | 8-March | Webflow | Monthly Hosting | Website | $99 | | 9-March | Canva | Monthly Subscription | Software | $29 |
