Cashier Job Description: Duties, Skills and Till Security Tips

A cashier job description covers processing customer payments accurately and quickly, handling cash, card and contactless transactions, issuing refunds, balancing the till at the start and end of each shift, and delivering friendly customer service at the point of sale. Cashiers also play a key role in loss prevention, because the till is where errors, fraud and theft most often show up.

This guide sets out cashier duties and responsibilities, the skills and training the role needs, practical cash handling and till security good practice, how the role works in airports and duty free, and a copy-ready template for employers.

What does a cashier do?

A cashier, sometimes called a checkout operator or retail cashier, takes payment for goods and services. In supermarkets and convenience stores the role is focused on checkout. In department stores, airports, hotels and leisure venues, cashiers may also handle currency, gift cards, loyalty schemes, deposits or bill payments.

While the core task looks simple, a good cashier combines speed, accuracy and customer care, and follows controls that protect the business from loss. Many retailers now mix staffed tills with self-checkouts, and cashiers often supervise self-service areas too, approving age checks and resolving errors.

Key cashier duties and responsibilities

• Processing transactions: scanning items, applying discounts and promotions correctly, and taking cash, card and mobile payments.
• Giving change accurately: counting change back to the customer and checking notes received.
• Refunds, exchanges and voids: following policy and obtaining authorisation where required.
• Opening and closing the till: checking the float, recording takings and reconciling the till against sales.
• Age verification: asking for valid photo ID before selling alcohol, tobacco and other age-restricted products, in line with the store’s policy.
• Customer service: greeting customers, answering questions, promoting offers and loyalty schemes, and resolving minor complaints.
• Security: watching for counterfeit notes, card fraud and distraction tactics, and reporting concerns.
• Bagging and packing: helping customers pack goods and handling fragile or high-value items with care.
• Keeping the checkout area tidy: restocking bags and impulse lines and keeping the area safe.
• Supporting the team: helping with replenishment, queue management and self-checkout supervision during quieter periods.

Cash handling and till security good practice

Strong till controls protect both the business and the cashier. The following practices are widely used across UK retail:

1. One cashier, one till: where possible, assign each till drawer to a single person per shift so discrepancies can be traced.
2. Count the float at the start: count and sign for the opening float before trading, ideally witnessed.
3. Keep the drawer closed: close the drawer between transactions and never leave a till open or logged in when away.
4. Leave the note on the ledge: place the customer’s note on top of the drawer until change has been given, to avoid “I gave you a twenty” disputes.
5. Count change back aloud: it reduces errors and helps deter quick-change tricks.
6. Check notes: learn the security features of genuine notes and use detector equipment where provided. If a note is suspected to be counterfeit, follow your store procedure; the Bank of England advises contacting the police.
7. Make regular cash lifts: remove excess cash to the safe at set limits so the drawer never holds more than necessary.
8. Control refunds and voids: require manager authorisation and a reason code, and review exceptions reports regularly.
9. Protect PINs and card data: never handle a customer’s card unnecessarily or look at their PIN entry.
10. Reconcile and record: cash up at the end of the shift, record any variance honestly and escalate significant differences straight away.

These controls work best as part of a wider loss prevention approach. Our article on how duty-free retailers can reduce loss prevention risk covers how till procedures fit with CCTV, stock controls and staff training.

Skills and qualities

• Accuracy with numbers and confidence handling money
• Speed without cutting corners, especially at peak times
• Friendly, clear communication and patience with customers
• Honesty and integrity, as cashiers are trusted with cash and card data
• Attention to detail for prices, promotions and ID checks
• Confidence refusing a sale politely when ID is not provided
• Basic IT skills for electronic point of sale systems
• Ability to stand for long periods and stay focused through a shift

Qualifications and training

Cashier roles rarely require formal qualifications. Employers usually value a positive attitude, good basic maths and customer service experience. Retail apprenticeships, such as the Level 2 Retailer standard, can provide a structured start, and some employers ask for GCSEs in English and maths.

Typical training includes:

• Till and EPOS system operation
• Cash handling, float procedures and cashing up
• Age verification and how to refuse a sale
• Counterfeit note awareness and card fraud prevention
• Conflict management and dealing with difficult customers
• Airport ID vetting and airside induction for travel retail roles

Licensed premises must have an age verification policy requiring anyone who appears under 18, or an older age set by the policy, to show photo ID with a date of birth before buying alcohol. Many retailers go further and run a voluntary Challenge 25 policy, asking anyone who looks under 25 for ID, so cashiers need to be confident asking.

Cashiers in airports, duty free and hospitality

WWSG supplies cashiers alongside sales associates, customer service assistants and front-of-house staff for airport, retail and hospitality clients. Cashiering in an airport is noticeably different from a high street store.

Airport and duty-free cashiers

• Boarding pass checks: duty-free stores typically scan boarding passes at the till so sales are recorded against the passenger’s destination.
• Duty-free rules: since 1 January 2021, passengers leaving Great Britain for EU destinations have been able to buy alcohol and tobacco duty free, while airside VAT-free sales of other goods ended.
• International customers: cashiers serve passengers from many countries, so clear communication, patience and sometimes additional languages are valuable. Some stores accept selected foreign currencies or offer card payment in the customer’s home currency; where this applies, cashiers need training on the store’s exchange rates and procedures.
• Time pressure: customers may be close to boarding, so speed and accuracy matter.
• Security environment: airside cashiers must pass airport ID checks and follow strict rules on passes, prohibited items and reporting.

Hospitality and leisure

In hotels, restaurants and venues, cashiers may handle bills, deposits, tips and split payments, and often work late shifts. Accuracy and calm under pressure are equally important when queues build at events.

Pay and career progression

Cashier pay varies with location, employer and shift pattern, with premiums sometimes paid for early or late shifts. From 1 April 2026, the National Living Wage for workers aged 21 and over is £12.71 an hour, with lower minimum rates for younger workers and apprentices.

Progression routes include:

1. Senior cashier or cash office assistant, handling cash collections, safe counts and banking.
2. Checkout or front-end supervisor, managing till teams, breaks and authorisations.
3. Retail supervisor or store manager, taking responsibility for the wider shop.
4. Specialist roles in loss prevention, cash management or retail operations.
