New staff hit the same snags: unfamiliar screens, wrong product lookups, payment prompts that stall, returns, and a line growing while you work it out. This guide walks through a real retail workflow, from opening the register to closing out your shift. Button names vary by provider, but the sequence stays the same.
Key Takeaways
- Check your login, scanner, card terminal, and receipt paper before the first customer.
- Ring every sale in order: find items, verify prices, apply discounts, take payment, issue the receipt.
- Returns, voids, discounts, and offline sales follow store policy and may need a manager.
- Accurate closeout and prompt issue reporting protect inventory and cash.
When Should You Use a POS System, and What Do You Need First?
When a POS fits the workflow
Use the POS for the transactions your store has enabled, including sales, card and cash payments, receipts, returns, exchanges, gift cards, and customer lookup.
Avoid workarounds that corrupt records:
- Writing up a sale by hand with no plan to enter it later
- Using a coworker's login
- Ringing a generic item when the correct SKU exists
Your environment matters too. Fixed counters, floor-based mobile selling, seasonal rushes, pop-up sales, and large catalogs each call for slightly different habits.
What you need before you start
- A personal login: permissions for sales, discounts, returns, and cash handling. PCI DSS v4.0.1 requires unique user IDs and job-based access for in-scope systems.
- Working hardware: a powered terminal, scanner, receipt printer, cash drawer, card reader, and a network connection if your setup needs one.
- A clean catalog: prices, tax settings, barcodes, and variants set up by a manager.
- Written procedures: refunds, exchanges, price overrides, offline sales, and who to call when something breaks.
Specialty retailers often run a retail-focused platform such as NCR Voyix Counterpoint, supported by AMS Retail Solutions. Whatever the platform, follow the configuration and permissions your store has set.
How to Use a POS System (Step-by-Step)
Do the steps in order. Skipping ahead is how pricing, payment, and inventory errors start.
Setup and Preparation
- Sign in with your own credentials.
- Confirm you're on the correct register or store location.
- Check that the scanner and card terminal are connected and the printer has paper.
- Count the opening drawer amount per store policy. In Square's workflow, for example, you enter starting cash to begin a drawer session.
- Read any on-screen alerts. If equipment or cash looks wrong, tell a supervisor before serving anyone.
Initiating a Sale
Greet the customer, then scan each item or search for it by hand. Check the description and price on screen, and enter the right quantity or unit of measure.
If something is unusual, stop and verify. That includes variants, tax-exempt purchases, and customer-specific pricing. Don't guess, and don't pick a similar SKU to keep the line moving.
Tax exemptions deserve care. In Texas, for instance, qualifying agricultural purchases require an exemption certificate and Ag/Timber Number, and the retailer collects tax without it. Rules vary by state, so ask your manager what documentation your store needs.
Operating the POS Correctly
- Review the cart with the customer.
- Apply only authorized discounts.
- Confirm the total and sales tax.
- Select the payment method and follow the terminal prompts.
- Offer a printed or digital receipt.
- Confirm the transaction shows as completed before handing over merchandise.
Returns, exchanges, voids, and refunds are separate workflows. Follow your store's approval process for each.
Monitoring During Use
Watch for these issues as you work:
- Duplicate line items
- Wrong quantities
- Declined or interrupted payments
- Scanner failures
- Surprise price differences
- Receipts that won't print
When a payment screen stalls, don't tap "charge" again. Check the transaction status first and follow your store's recovery process.
Square notes that a status report can take up to 10 minutes to show an incomplete transaction, and a canceled payment may still appear as a pending charge. A pending bank entry alone doesn't prove a sale went through.
Shutting Down or Completing Use
After each sale, return the customer's card, secure the cash, and leave the register ready for the next person.
At shift end, don't walk away until you've finished the closeout:
- Review sales and payment summaries
- Count cash with the required witness or manager
- Record any discrepancy as it is, never adjust figures informally
- Log out or hand off per store procedure
Where POS Systems Are Commonly Used in Retail
The same basic workflow runs through garden centers, nurseries, farm markets, feed and seed stores, outdoor sporting goods shops, and other specialty retailers. What changes is the catalog and how products are handled.
Specialty situations that need extra care:
- Weighed or fractional items: Feed, seed, and bulk goods may sell by weight. NIST notes that commercial scales must meet state requirements, so use only the scale your store has approved.
- Seasonal inventory: Plants and seasonal goods swing fast, and counts need regular attention.
- Variants: Size, color, and model-year SKUs are easy to mix up.
- Serialized or regulated items: These often need extra steps and manager approval.
- Special orders and deposits: Know how your system records a deposit and applies it to the final sale.
- Customer accounts: Grower or contractor accounts have their own pricing and billing.
Which of these your POS supports depends on its setup, so ask your manager.
Fixed counters and mobile selling differ, too. At a counter, you control the screen and the receipt.
On the lot or sales floor with a handheld, show the customer the total, confirm payment before you leave, and deliver the receipt. Landscape supply yards and farm markets often sell this way during planting and harvest rushes.
Best Practices for Using a POS System Effectively
Verify before you complete
- Compare the item in your hand to the screen
- Check quantity and price
- Read the total back when it helps
Protect access and customer data
- Use only your own login, and never share passwords or approval codes
- Lock the screen when you step away
- Never write down or keep card numbers
- Handle customer contact details per store policy
Federal FTC guidance says electronically printed receipts may show no more than the last five digits of a card number.
Use approvals and corrections properly
Call a supervisor for:
- Refunds and voids
- Price overrides and big discounts
- Drawer adjustments
- Any transaction that looks duplicated or incomplete
Prepare for interruptions
Know your store's plan for scanner, printer, payment, power, or internet failures. If offline selling is supported, use only the approved procedure.
Offline card payments carry risk. Square warns that declines aren't reported while offline, and sellers bear responsibility for expired or declined payments. Learn how and when your store syncs those sales.
Keep the system accurate
- Complete required stock checks
- Report recurring SKU or price errors
- Keep scanners and screens clean and unobstructed
- Note unresolved issues for the next shift and support team
Consistent habits make checkout faster, inventory data more reliable, shrink easier to spot, and cash easier to review. AMS Retail provides 24/7 support for unexpected POS problems if your store uses their service.
Conclusion
Learning a POS comes down to a steady routine: prepare the register, enter accurate product information, verify the transaction, complete payment, and document exceptions.
Pair hands-on practice with written procedures and a manager who answers questions. That combination lets you work with confidence while protecting customers, inventory counts, and cash accountability.

How do you process a sale on a POS system?
Log in, scan or select items, verify quantities and prices, apply authorized discounts, take payment, issue the receipt, and confirm the sale is complete and inventory is updated.
What should retail staff do if the POS loses internet access?
Follow the store's offline policy and don't repeatedly retry a payment. Record the issue, and contact a manager or support if payment status is unclear.
