The hardest decision for retailers is selecting the proper POS system for retail. It may seem like it will be easy to find the best one, but that's not always the case. Every vendor will show you a great demo of their point-of-sale system.

Every pricing page includes a "starting at" price that is never quite what you'll pay on your invoice. And the price of getting it wrong isn't simply a loss of funds — it's months of retraining personnel, transferring stock data, and reassuring customers that the points they just earned are now gone.

This checklist has been designed to cut through that. Run through it before you sit through another sales call, and you'll enter every vendor conversation already knowing what truly matters for your store.

The Checklist - POS System for Retail

Save this, screenshot it, or print it out — whatever keeps it front of mind when you're calling vendors.

• Depth of inventory — Does it support your actual SKUs, variants (sizes, colors, flavors), and inventory across multiple locations in real time?
• Hardware compatibility — Will it integrate with your existing receipt printers, scanners, and card readers, or will you need a full hardware purchase?
• Payment processing terms — Is the processor locked to the vendor, and what is the real per-transaction fee — not just the advertised rate?
• Compliance features — Does it verify ID and automatically flag restricted SKUs if you sell age-restricted or regulated products?
• Offline mode — Will the register still process sales without internet connectivity, and does it sync cleanly once you're reconnected?
• Reporting — Can you get the reports you need (sales by hour, shrinkage, best/worst sellers) without exporting to a spreadsheet first?
• Staff permissions — Can you restrict what cashiers vs. managers are able to void, discount, or refund?
• Contract length and exit terms — Month-to-month, or locked in for a year or more? What does cancellation actually cost?
• Support hours — Live support during the hours you're actually open, including weekends and holidays?
• Onboarding and data migration — Will your existing inventory and customer data be brought into the system, or are you starting from zero?

If a vendor can't give you a clear answer on more than two or three of these, that's information too.

Must-Have Features, Expanded

The checklist above is the short version. A few of these deserve extra attention, since they're where most retailers get burned.

Inventory that reflects how you actually sell. Inventory management isn't much of a challenge for a store selling 200 straightforward items. It breaks down at the 2,000+ SKU level with variants — a vape shop tracking flavor, strength, and bottle size as separate SKU lines, or a boutique tracking size and color across multiple vendors. Don't just ask "Does it do inventory?" Ask, "How does it perform when the inventory is highly variable?"

Compliance is a must if you're in a regulated category. If you sell tobacco, vape, alcohol, CBD, or anything else with an age or licensing restriction, a generic retail POS may not have been built for you. You want the ability to scan ID at checkout, automatic age-gating tied to SKU, and ideally a compliance log you can pull when audited. This single feature alone rules out a lot of "best POS system" options before pricing even comes into play.

Reporting you'll actually use. Most systems can generate a sales report. Few can tell you which products are quietly costing you money, which employee has an unusual refund rate, or which hour of the day you're overstaffed. Before buying, ask to see the real reporting dashboard — not a features list, the actual screen — and check whether it answers the questions you actually ask as an owner.

Hardware flexibility. Some POS providers require you to buy their proprietary terminals, which is fine if you're starting from scratch but costly if you already have hardware that works. Ask directly: "What hardware am I required to buy, and what can I continue using?"

Questions to Ask a Vendor Before Signing

Bring these to the sales call. A reliable vendor will answer them without hesitation.

1. "What's my all-in monthly cost, including payment processing, at my actual transaction volume?" — Not the sticker price. Have them run the math on your real numbers.
2. "Is your payment processor optional, or required?" — Some systems lock you into their processing at above-market rates. Know this before you sign.
3. "What is the early cancellation fee and notice period — in writing?"
4. "Can I export all my data if I switch systems later?" — This should be a genuine answer, not an invitation to re-enter everything by hand.
5. "What's your average support response time, and does it vary by plan tier?" — Cheaper plans sometimes come with slower support queues.
6. "How long does onboarding take for a store my size?" — Compare their answer against your own timeline. If you need to be live in two weeks and they quote six, that's a real constraint.

Retail POS Pricing and Contracts: Red Flags

A few patterns show up often enough that they're worth calling out explicitly.

• "Free" hardware tied to a long contract — The hardware usually isn't free; its cost is built into a higher processing rate over the contract term, and you often can't tell that from the pricing page.
• Processing rates quoted without the per-transaction fee — A 1.9% rate looks very different once a $0.10–$0.30 per-transaction fee is factored in against your actual transaction volume.
• Auto-renewing annual contracts with a narrow cancellation window — Some contracts only let you cancel during a specific window once a year. Read the renewal terms before you sign, not when you're trying to leave.
• Vague answers about data ownership — If a vendor can't clearly explain how you get your inventory and customer data out if you leave, treat that as a real risk, not a minor detail.
• Compliance features sold as a paid add-on — If age verification or compliance logging is gated behind a higher tier, factor that into your real monthly cost from the start.

Running the Checklist Against Quickvee

If you sell in a specialty or age-restricted category — smoke, vape, tobacco, CBD, or similar — it's worth running this exact checklist against QuickVee specifically, since it's built around those constraints rather than treating them as an afterthought:

• Inventory depth — Built for high-SKU, high-variant catalogs (flavor, strength, size) rather than a simple product list.
• Compliance — ID scanning and age-gating are core to the system, not a bolted-on module, with a compliance log you can pull on demand.
• Hardware — Works with standard retail hardware rather than forcing a proprietary terminal purchase.
• Multi-location — Inventory and reporting sync across locations in real time, which matters once you're running more than one store.
• Support — Live support during real retail hours, not a ticket queue.

The point isn't to take that on faith — it's to ask Quickvee (or any vendor you're evaluating) the same questions above and see how the answers actually hold up.

Before You Buy

The checklist at the top of this post is the fast version. If you only do one thing before signing a contract, do this: get the vendor's answers to the six questions above in writing, and compare them against what their pricing page and sales rep told you. 

The gap between those two things — if there is one — is usually where the real cost of a "cheap" POS system shows up six months in.
