Best Way to Keep Stock Records for a Small Shop

Quick answer

Every stock record should answer four basic questions: **what came in, what went out, what was adjusted and what should remain**. A notebook can work for a very small operation, but a digital system becomes more useful as products, staff and daily transactions increase.

What information should I keep for each product?

At minimum:

- Product name. - Category. - Quantity available. - Cost price. - Selling price. - Quantity received. - Quantity sold. - Damaged, expired or lost quantity. - Supplier where useful.

For businesses dealing with expiry dates or batches, batch-level records may also be necessary.

Can I use a stock notebook?

Yes, especially when the business is extremely small and has few products.

The problem appears when the number of products and daily transactions grows. Staff may forget to update the book, handwriting may be unclear and calculating remaining stock becomes slow.

A notebook also makes it difficult to answer questions such as “Which product sold most this month?” without manually reviewing many pages.

Is Excel better than a notebook?

Excel can be a major improvement because it allows calculations, sorting and filtering.

However, Excel still depends on disciplined manual entry. In a busy shop, attendants may be making sales while another person edits the file, and mistakes can occur if the sheet is not designed carefully.

Excel is useful for analysis, but a POS is usually more convenient when every sale should reduce stock automatically.

How should stock enter the system?

When new stock arrives, record the quantity received and the purchase cost. If the supplier invoice says 10 cartons but only 9 arrived, record what was actually received and resolve the supplier difference.

If cartons are later sold as individual units, the system should understand the relationship between purchase and selling units where required.

How should stock leave the system?

Normal sales should reduce stock automatically.

Other stock reductions should be categorised rather than hidden:

- Damaged. - Expired. - Personal use. - Promotional/free issue. - Transfer to another branch. - Missing after count.

This makes stock differences easier to understand.

What is a stock adjustment?

A stock adjustment changes the recorded quantity when a verified reason exists.

For example, the system says 50 units but a physical count finds 48. An authorised user may adjust the quantity by -2 and select a reason.

Good systems keep the adjustment history instead of silently changing the figure.

How often should I perform a physical stock count?

There is no one schedule for every business.

High-value or easily stolen items may be counted daily or weekly. Fast-moving products may also need frequent checking. A broader count can be done weekly or monthly depending on the scale of the business.

The important thing is to compare physical quantity with system quantity and investigate differences.

How can Bizinesiyo help?

Frequently asked questions

**What is opening stock?** Opening stock is the inventory quantity or value available at the beginning of a reporting period.

**What is closing stock?** Closing stock is what remains at the end of the period after purchases, sales and adjustments.

**Why does system stock differ from physical stock?** Common causes include unrecorded sales, receiving errors, damage, theft, wrong quantities and incorrect adjustments.

**Can barcode scanning help?** Yes. Barcodes can speed product identification during sales, receiving and counting when products have suitable codes.

**Do I need internet to keep digital stock records?** That depends on the software. Some systems require internet while offline-capable systems can continue selected operations locally and sync later.
