“Bookkeeping” is a word that makes many shop owners back away, because it sounds complicated and time consuming. In reality, basic shop bookkeeping needs no accounting skills at all. Just record “money in” and “money out” fully, and you’ll know your shop’s real profit. This article covers easy ways to do it on your phone.
Why even a small shop should keep books
Not for tidy numbers, but to:
- Know your real profit: not just guessing “there’s probably some left”
- Catch leaks: see at once which month costs spiked oddly
- Plan ahead: know which months sell well and how much to stock
- Prepare for tax: have the numbers ready when you need to file
Shops that don’t record anything usually only realise they’re losing money once the cash runs out.
What basic shop bookkeeping needs to record
You don’t need complex company style accounting. These 3 things are enough for a small shop:
- Income (money in): each sale, or the daily closing total
- Expenses / cost (money out): stock purchases, ingredients, consumables
- Recurring expenses: rent, water, electricity (once a month)
Just take these 3 and compute profit = income − all expenses, and you already see a clear picture of your shop (read the detailed method: How to calculate shop profit).
3 ways to keep shop books, pros and cons
1. Notebook / paper Simple, zero cost, but easy to lose and slow to total up. No overview.
2. Excel / Google Sheets Calculates automatically, but you have to open a computer and type it in. Busy shops often don’t update it consistently.
3. A mobile / LINE bookkeeping app The most convenient for a small shop. Record right when you sell or buy stock, no computer needed, and it summarises profit automatically.
Tip: record “fully” without eating up time
The big problem with bookkeeping is “too lazy to record”, so the data ends up incomplete. Fixes:
- Record immediately, don’t wait: log at the moment of selling or buying, not all at once later
- Snap the receipt instead of typing: faster, and you won’t forget
- Record things without a receipt too: morning ice, market vegetables, type a quick amount
- Set recurring expenses once: let the system deduct rent / electricity every month automatically

FAQ
Q: I don’t know bookkeeping at all. How do I start? A: Start with just two columns, “money in” and “money out”, every day. That’s enough for a small shop, no complex standard accounting needed.
Q: Do I have to record every single bill? A: A daily sales total is fine if the shop is very busy, but “cost / expenses” should be recorded every time, since those are what throw off profit if missed.
Q: Is shop bookkeeping related to filing tax? A: Yes. Having complete income and expense records makes tax preparation much easier. Read next: Do small shops need a POS? + run your shop with LINE
In short: shop bookkeeping doesn’t have to be hard. Just record money in and money out fully every day on your phone, let the system summarise profit, and you’ll know your shop’s health without guessing.
