9 Best POS Systems for Market Vendors of 2026

Square fits the market stall well because the free plan covers what a booth needs and nothing has to be bolted to a counter. Square Free costs $0 a month per location, and in-person card payments cost 2.6% + 15¢. A vendor can start with Tap to Pay on iPhone or Android and add the $59 Square Reader for contactless and chip when chip cards come up. Offline payments are included with every plan, which matters in a field or parking lot with weak signal, but Square declines any offline payment if the device does not reconnect within 24 hours of the first one, and the seller carries the risk of declined cards. Next day transfers are standard. The trade-off is the card rate: SumUp charges 10¢ per sale instead of 15¢, and PayPal charges 2.29% + $0.09. Lower Square rates sit in Square Plus at $49 and Square Premium at $149 per location a month, which few booth sellers need.

PayPal Point of Sale, the US name for what used to be PayPal Zettle, is the cheapest way on this list to start taking chip cards at a booth. There are no monthly or setup fees, the first Card Reader costs $29, and card-present payments cost 2.29% + $0.09, below the 2.6% rates of Square Free and SumUp. QR code transactions cost the same 2.29% + $0.09, so a printed code on the table gives customers who prefer PayPal another way to pay. The all-in-one Terminal at $199, or $239 with a barcode scanner, suits vendors who want one device instead of a phone and a reader. Money reaches the PayPal balance in minutes. The downsides are a $79 price for each extra reader, 3.49% + $0.09 for keyed cards, and PayPal's note that transactions may be held or delayed for review.

SumUp keeps the cost of a market day close to zero when nothing sells. The standard option asks for a one-time hardware cost and then charges 2.6% + 10¢ for each card-present payment, with no monthly minimums and no hardware rental. That 10¢ fixed fee is 5¢ below Square Free, which adds up for vendors who sell many small items such as jam, flowers or coffee. SumUp promises next-day payouts with every product, and money paid into the free SumUp Business Account is available by 7am the next day, including weekends and public holidays, which suits Saturday and Sunday markets. The limits are on the software side. POS Plus at $49 a month adds the paid feature tier, and keyed card numbers or online payments cost 3.5% + 15¢. For a single seller who mostly takes taps and chips at one booth, the free option covers the job.

Helcim makes sense for vendors who do enough card volume that the difference between a flat rate and wholesale card costs matters. It charges no account monthly fees, minimums, software fees or statement fees, and prices card payments as interchange plus a published margin, with volume discounts. For a booth, the Helcim Card Reader costs $199 and has an all-day battery, while the Smart Terminal costs $349, or $32 a month for a year, and combines a POS, receipt printer and 4G connectivity in one unit. That 4G option, $7 a month on Helcim hardware, solves the no-Wi-Fi problem at rural markets. Tap to Pay on iPhone works too, at an extra 10¢ per transaction. Deposits arrive the next business morning. The weak points for small sellers are the upfront hardware price and fees that change with each card type, which makes a day's cost harder to predict than SumUp's flat rate.

Shopify POS is the right pick when the market booth is a sideline to an online shop. Every paid Shopify plan includes casual in-person selling, so a maker who already lists products on Shopify can sell the same items at a craft fair and see stock and sales in one back office. Shopify lists draft orders, multichannel gift cards, reporting and analytics as included in every plan, and the back office scales to more than 1,000 locations. POS Pro, a per-location add-on, brings unlimited staff accounts, permissions, inventory counts, purchase orders and retail analytics, which a single booth rarely needs. The catch is cost: unlike Square, SumUp or PayPal, there is no free plan, so a vendor without an online store pays a monthly subscription for features they will not use. Shopify showed us local-currency prices from our location, so the USD price is marked as pending.

Clover Go pairs a pocket Bluetooth reader with Clover's software plans, which suits vendors who want the reporting and customer tools of a larger POS on a phone. The reader takes chip, swipe and contactless payments, and Clover estimates about 160 dip, 160 swipe or 130 contactless transactions per charge, enough for a long market day. It works over Wi-Fi or cellular, and in a dead zone it can take payments offline that are authorized once the device reconnects. Tap to Pay on iPhone also works in the Clover Go app. Clover sells two plans, Starter and Essentials, and Essentials adds detailed sales and tax reports, real-time sales tracking, a customer database, promotions, loyalty and gift cards. Rapid Deposit puts funds in place within minutes for 1.75%. Accounts need credit approval, and the plan prices did not load for us, so pricing is pending.

Loyverse is a free POS app rather than a payment processor, which makes it a good fit for vendors who care more about tracking items and repeat customers than about the card rate. The point of sale, 31 days of sales analytics, essential inventory with low-stock alerts, a loyalty program, a customer display and multi-store management are all free, and no credit card is needed to sign up. It runs on a phone or tablet the vendor already owns. Three paid add-ons cover unlimited sales history, employee management and advanced inventory, each with a 14-day free trial. The gap for a market booth is payments: Loyverse connects to processors such as SumUp and Zettle, so the seller still sets up and pays a separate provider. Loyverse showed add-on prices in euros from our location, so the USD price is pending.

Payanywhere suits vendors whose sales are mostly small, because the pay-as-you-go plan charges 2.69% for every swipe, dip or tap with no fixed cents added. On a $4 sale that costs about 11¢, less than Square Free or SumUp, while on a $100 sale PayPal's 2.29% + $0.09 is cheaper. The 3-in-1 Bluetooth reader takes EMV chip, contactless and magstripe cards and pairs with a phone or tablet, and Tap to Pay on iPhone works with no reader at all. Payanywhere includes inventory, employee and customer management, and offers same day or next day funding. Keyed payments and invoices cost 3.49% + $0.19. There is no monthly fee, but a $3.99 inactivity fee applies to merchants who go 12 months without a transaction, which matters for vendors who only sell at an annual fair. The service is available only in the United States.

Venmo for Business is a payment tool, not a full POS, but it earns a place because so many market shoppers already pay this way. A business profile links to a personal Venmo account, costs nothing to set up and charges no monthly fee. Customers who scan the booth's Venmo QR code pay a 1.9% + $0.10 fee for the seller, the lowest rate on this list. Card payments are possible with Tap to Pay straight from the phone, with no extra hardware, at 2.9% + $0.09, which is more than Square, SumUp or PayPal Point of Sale charge for a tap. Payments go to the Venmo balance, and business income stays separate from the personal feed. Venmo does not list item catalogs, stock counts or sales reports by product, so vendors who need those should pair it with a POS app or choose PayPal Point of Sale, which also accepts QR payments.
