Why Are Your EPOS Reports Diverging from Actual Stock Usage in Hospitality?

Many hospitality operators rely on EPOS systems to track sales, monitor product performance, and analyse gross profit. These systems offer valuable insights into what has been sold, but it is common to find that the figures in their reports do not match the actual stock usage measured through physical stock audits. This mismatch can cause confusion and concern, especially when managing costs and ordering supplies.

Understanding why these differences occur is essential for hospitality businesses aiming to control stock effectively and maintain accurate financial records. This post explains how EPOS systems and stock audits work, why their results often differ, and what operators can do to bridge the gap.

How EPOS Systems Track Sales

EPOS systems record transactions as products are sold at the till. When a drink is rung up, the system deducts stock based on predefined product setups. For example:

• A single gin deducts 25ml of spirit

• A pint of lager deducts one unit from the keg

• A glass of wine deducts 175ml from the bottle

  
  

These assumptions help generate sales reports and estimate stock usage automatically. However, the accuracy of these deductions depends entirely on how precisely drinks are poured and recorded at the point of sale.

If staff pour larger measures than the system assumes or if products are not entered correctly, the EPOS data will not reflect actual consumption. The system assumes perfect consistency, which rarely happens in a busy hospitality environment.

How Stock Audits Measure Actual Consumption

Stock audits take a hands-on approach by physically measuring stock levels and movements. This process includes:

• Counting bottles, kegs, and other stock items

• Measuring remaining quantities in partially used containers

• Reviewing purchase invoices and deliveries

• Comparing expected usage based on sales with actual stock depletion

  
  

Stock audits reveal the real amount of product used during a trading period, including wastage, spillage, and unrecorded consumption. This method provides a more accurate picture of stock flow but requires time and effort.

Why Till Reports and Stock Audits Often Don’t Match

Several factors cause discrepancies between EPOS reports and actual stock usage:

Inconsistent Pouring Measures

Staff may pour drinks larger or smaller than the standard measures set in the EPOS system. For example, if a bartender pours 30ml of gin instead of 25ml, the system underestimates stock usage. Over time, these small differences add up, causing stock levels to drop faster than sales figures suggest.

Wastage and Spillage

Breakages, spills, and ullage (the space left in bottles after pouring) are common in hospitality settings. These losses are not recorded in EPOS data because they do not generate sales transactions. As a result, stock audits show higher consumption than sales reports.

Staff Drinks and Complimentary Items

Drinks given to staff or customers as comps often go unrecorded in the EPOS system. These untracked items reduce stock but do not appear in sales data, leading to discrepancies.

Incorrect Product Setup

If the product setup in the back office do not match actual serving sizes or packaging, the system’s deductions will be inaccurate. For example, if a wine glass is set to deduct 175ml but the venue serves 200ml, stock usage will exceed reported sales.

Human Error at the Till

Mistakes such as forgetting to ring up a sale, entering the wrong product, or voiding transactions incorrectly can distort sales data. These errors affect the accuracy of EPOS reports and create gaps when compared to stock audits.

Practical Steps to Align Till Reports with Actual Stock Usage

To reduce discrepancies and improve stock control, hospitality operators can take several practical steps:

• Train staff on consistent pouring: Use jiggers or measured pourers to ensure drinks match EPOS assumptions. Regular training helps maintain accuracy.

• Record wastage and comps: Implement procedures to log spills, breakages, and complimentary drinks so these are accounted for in stock management.

• Review and update product setups: Regularly check that product measures in the back office to reflect actual serving sizes and packaging. Adjust as needed.

• Conduct frequent stock audits: Regular physical counts help identify discrepancies early and allow for timely corrections.

• Use EPOS data as a guide, not absolute truth: Understand that sales reports provide estimates based on ideal conditions. Combine them with stock audits for a full picture.

• Investigate unusual variances: When stock usage and sales diverge significantly, review staff practices, stock handling, and EPOS entries to find causes.
