A weekly checklist with adjustable time blocks
A backlog of unrecorded transactions makes it harder to connect a payment with an invoice or an expense with its receipt. A scheduled review gives you a place to reconcile those records before details are lost.
The 15-minute schedule below is an illustrative allocation, not a tested completion time. Allow more time for transaction volume, missing documents, payroll, sales tax or other complexity.
Pick a time and protect it. Friday afternoon works well — the week is fresh and you can close it out before the weekend. Make a coffee, open your banking app and your tracking sheet, and run the checklist below.
The 15-minute checklist
Here’s the whole routine. Each step has a rough time budget so you don’t get stuck on any one of them.
| Step | What you do | Roughly |
|---|---|---|
| 1 | Record this week’s income | 3 min |
| 2 | Log expenses + file receipts | 4 min |
| 3 | Move your tax slice to a separate pot | 2 min |
| 4 | Chase anything overdue | 4 min |
| 5 | A two-line note to future-you | 2 min |
You don’t need accounting software for this. A single spreadsheet with tabs for Income, Expenses, and Invoices Sent will carry you a long way. If you outgrow it later, the data exports cleanly into something fancier.
1. Record what came in
Open your bank account and write down every payment you received this week: date, who from, amount, and what it was for. That’s it. If a client paid an invoice, mark that invoice as paid in your tracker so you stop chasing money that’s already in.
The trick is doing this from your actual bank balance, not from memory. Money you expected and money that landed are different things, and only one of them counts.
2. Log expenses while you remember them
Go through the week’s spending and capture anything business-related: software subscriptions, that stock photo licence, a co-working day pass, postage, the train fare to a client meeting. For each one, note the date, amount, vendor, and a one-word category — Software, Travel, Marketing, and so on.
Snap a photo of paper receipts and drop them in a dated folder on your phone or cloud drive. A receipt you photographed in March is worth a lot more than one you’re trying to recreate the following January. Whether a given expense is actually deductible depends entirely on where you live and your situation, so keep everything and let the rules sort it out later.
3. Set aside your tax slice
This is the step people skip, and it’s the one that saves your skin. Every time income lands, a chunk of it isn’t really yours — it belongs to a future tax bill. Move it out of reach now.
Base tax-reserve transfers on an estimate for your jurisdiction, business structure, income and payments already made. This guide does not recommend reserving a quarter or a third of receipts. Keep the estimate and its assumptions with your records and update them when the facts change.
Separating reserved money can make its intended purpose easier to track, but it does not guarantee that the amount will cover the eventual bill.
4. Chase what’s late
Scan your Invoices Sent tab for anything past its due date. For each overdue one, send a short, friendly nudge — a two-line email does the job: “Hi Sam, just checking this invoice is on track for payment. Let me know if you need anything from my end.” No drama, no apology.
A weekly review can flag invoices that became overdue since the last check. Follow the agreed terms and record responses; a reminder may not resolve a dispute or inability to pay. The invoice generator formats an invoice, but does not track bank receipts or send reminders.
5. Leave a note for future-you
Last two minutes: jot one or two lines somewhere — the top of the spreadsheet works. “Waiting on Acme (€800, due 12th). Need to ask landlord for office rent receipt.” Next week you pick up exactly where you left off instead of reconstructing your own brain from scratch.
One illustrative week, start to finish
Illustrative weekly record: the following fictional designer has two customer payments and three expenses to reconcile. Names, prices and the reserve percentage are example inputs.
Income. Acme Studio pays invoice #41 for €1,200 and another client pays €350. Record both receipts and mark the corresponding invoices paid. Total receipts: €1,550.
Expenses. Example software cost €60, font licence €29 and work-related train fare €14. Keep the receipts and record €103 of expenses; tax deductibility depends on applicable rules.
Reserve. An illustrative 30% transfer from the €1,550 receipts is €465. This is a cash-allocation example, not a tax calculation or recommendation. Estimate your actual liability using the relevant tax rules; the remaining cash may still need to cover other business obligations.
Follow-up. Invoice #38 to Beta Co. for €600 is overdue under the example payment terms. Send a factual reminder and record the agreed next step.
Note. Record the invoice reference, amount, follow-up date and any response. Keep the original invoice and payment evidence together.
The result is a reconciled list of receipts, expenses, reserves and outstanding invoices. The time required depends on the number and complexity of your transactions; this is not a timed test.
Make it stick
Keep the same record categories and review all transactions since the previous reconciliation. If you miss a week, include the backlog and allow more time rather than stopping after an arbitrary 15 minutes.
A few months in, the spreadsheet quietly becomes the thing you reach for when a client asks “how much did I pay you last quarter?”, or when you want to know whether this month was actually any good. That clarity is the real payoff. The painless filing season is just a bonus.
