Why Most Sari-Sari Stores Lose ₱3,000/Month Without Knowing It

Ask a sari-sari store owner how much they made last month, and most can give you a rough number. Ask them how much they lost, and you'll usually get a blank stare. But losses are happening — and unlike revenue, they're invisible.

Shrinkage: The Three Silent Drains

"Shrinkage" is the retail industry term for inventory that disappears without a corresponding sale. In a sari-sari store, it comes from three main sources:

The Slow-Moving SKU Trap

The average sari-sari store carries 200–400 distinct SKUs. A significant portion of those — often 20–30% — move fewer than 5 units per month. Every slow-moving SKU represents capital tied up on your shelf: you paid the supplier, the cash is gone, and it's sitting in a product that might expire before it sells.

The problem isn't stocking that item once. The problem is reordering it automatically on every supplier visit because it "looks low" — without ever checking how long it's been sitting there. Without inventory data, you can't distinguish between an item that sells fast and one that you just keep restocking out of habit.

Why Inventory Variance Reports Change Everything

A variance report compares what your system says you should have (based on opening stock minus recorded sales) against what you actually count on the shelf. The gap — positive or negative — is your variance. It tells you:

• →Which SKUs are disappearing faster than they're being sold (shrinkage signal)
• →Which items aren't moving at all (dead stock signal)
• →Whether your supplier delivered exactly what you paid for (short-delivery detection)

Nexus7's NexusStock module generates automatic variance reports with each physical count. Most store owners who run their first variance report find ₱2,000–₱5,000 in unexplained losses within the first month. The ₱3,000/month figure in the headline is conservative.
