Why Stock Surpluses Can Be Just As Concerning As Shortages

When reviewing stock results, most operators focus immediately on shortages.

That makes sense—missing stock usually points to overpouring, wastage, theft, or poor controls.

But surpluses can be just as concerning.

A stock surplus may look positive at first glance. After all, having “more stock than expected” sounds better than having less. In reality, however, surpluses often indicate that something in the process is wrong.

Here’s why.

Surpluses Can Indicate Till or Sales Recording Errors

One of the most common causes of a surplus is sales not being recorded accurately.

Examples include:

• Staff selecting the wrong product on the till

• Drinks being rung under a similar but cheaper item

• Incorrect size/measure buttons being used

• Cash takings not reconciling to till sales

• Sales being recorded against the wrong category

In these cases, the stock appears “better than expected” not because performance improved—but because sales data is inaccurate.

Surpluses Can Reflect Missing Purchases or Delivery Errors

If stock has physically arrived but has not been recorded correctly in the figures, the result can show an artificial surplus.

Common causes include:

• Supplier invoices not entered

• Deliveries booked to the wrong period

• Credits/purchases processed incorrectly

• Stock transferred in without documentation

The stock may be physically correct, but the paperwork behind it is not.

Surpluses Can Highlight Specification or Setup Issues

Sometimes the figures point to issues with how products are configured or served.

Examples include:

• Cocktail specs not matching actual pour/build

• Recipe deviations in kitchen or bar preparation

• Product yields or measures set up incorrectly

• Pack sizes configured wrongly

Even small discrepancies in specifications can create misleading stock results over time.

Overall Surpluses Can Mask Product-Level Problems

A healthy overall surplus does not necessarily mean every area is performing well.

For example, a strong draught beer surplus may offset shortages elsewhere in the same period, creating the appearance of a favourable overall result.

That is why line-by-line analysis matters.

Looking only at the headline figure can hide:

• Individual product shortages

• Till variances on key lines

• Category-specific issues

• Emerging operational problems beneath the surface

Good Operators Investigate Both Directions

Well-managed venues do not treat surpluses as automatic good news.

They ask:

• Why is this product outperforming expectation?

• Are specs and measures being followed?

• Have all purchases been captured?

• Is the till setup correct?

• What is happening at product level beneath the headline result?

Because good stock control is about understanding the numbers—not simply liking the ones that look favourable.

Final Thought

A shortage tells you stock is disappearing faster than expected.

A surplus tells you something may be distorting the picture.

Both deserve attention.

The most valuable stock reports are not the ones with the best-looking numbers—they are the ones that reveal what is really happening operationally.
