10 Mejores Sistemas POS Para Gestionar el Flujo de Caja en 2026

Square gives small and midsize retailers an easy way to start taking in-person payments, manage stock, and grow into true omnichannel selling without a big upfront software bill.

You can launch with a free plan on a phone or tablet, then layer in retail-specific features—like barcodes, purchase orders, and multi-location stock control—as your store gets busier.

It’s especially useful if you want one system to cover in-store checkout, basic ecommerce, and simple reporting from day one.

Why I Picked Square

I picked Square because you can go from zero to working POS in an afternoon using just a card reader and your existing iOS or Android device—no custom hardware required.

You get a free entry-level plan with flat-rate processing, so you know your costs up front while you test new locations, pop-ups, or product lines. For growing retailers, Square for Retail adds barcode-based checkout, purchase order management, and vendor tracking, so you can keep shelves stocked and reduce manual stock counts.

Your online store, in-person sales, and social selling all feed the same catalog and customer profiles, which helps you avoid double-selling and messy spreadsheets.

On top of that, built-in options for loyalty, email and SMS marketing, and Square Banking mean you can keep payments, customer engagement, and cash flow inside one ecosystem instead of juggling five different tools.

Square Key Features

Beyond the quick setup, Square includes retail-focused tools that help you keep operations tidy as you scale.

• Retail Inventory Management: Track stock across locations, receive purchase orders, and use barcode labels to speed up counts and prevent out-of-stock surprises.
• Omnichannel Order Management: Sync in-store, online, and pickup orders in one dashboard so staff can see what needs packing, shipping, or holding at the counter.
• Retail Reporting And Analytics: View sales by location, category, or item, monitor margins, and use inventory reports to spot slow movers and bestsellers.
• Retail Hardware Options: Combine handhelds, registers, and terminals with scanners, printers, and cash drawers to build a checkout setup that fits your store layout.

Square Integrations

Integrations include QuickBooks Online, Xero, WooCommerce, Wix, Zapier, Linktree, Bookkeep, and Uber Eats.

Stax Pay is best suited for B2B sellers that invoice clients, run larger tickets, and want one place to handle card, ACH, and recurring payments across in-person and online channels.

You get subscription-style pricing, hardware flexibility, and tools built for longer sales cycles rather than quick retail taps.

Why I Picked Stax Pay

I picked Stax Pay because it matches how B2B revenue actually flows—quotes, invoices, recurring contracts, and bigger invoices instead of small walk-up sales.

You can send branded invoices, collect card or ACH payments, and set up recurring schedules from the same dashboard, so your AR team spends less time chasing checks and keying transactions. Level 2/3 data support helps you lower interchange on corporate and purchasing card payments, which matters when you’re running high-ticket invoices every month.

Subscription-based pricing gives you more predictable processing costs as volume grows, instead of rising percentage markups eating your margins.

On top of that, Stax is largely hardware-agnostic and offers omni-channel support, so you can keep existing terminals where it makes sense while still giving sales reps and finance a single view of cash coming in.

Stax Pay Key Features

In addition to pricing and B2B-focused billing tools, there are a few POS features that matter for finance and ops leaders.

• Customer Profiles And Card-On-File: Store payment methods securely, set preferred payment types, and reuse them across invoices and recurring schedules.
• Text2Pay And Payment Links: Send payment requests via SMS or hosted links so buyers can pay remotely without sharing card details over email.
• Inventory And Item-Level Reporting: Track items and categories through the dashboard to see which products, bundles, or SKUs drive the most revenue.
• Multi-Location And Channel Dashboard: View in-person, online, and invoiced payments together so you can reconcile by location, channel, or sales rep.

Stax Pay Integrations

Integrations include QuickBooks Online, Xero, Shopify, WooCommerce, BigCommerce, Magento, Salesforce, Keap, Shift4Shop, and WordPress.

Payment Depot uses a membership-style pricing model to help high-volume retailers rein in processing costs—especially if you’re tired of percentage markups eating into already thin margins.

It’s a strong fit for US-based merchants that want predictable card fees and the flexibility to pair processing with Clover, Vital Select, or existing POS hardware.

Why I Picked Payment Depot

I picked Payment Depot because the membership-based interchange-plus pricing gives you more predictable costs by swapping padded markups for a flat monthly fee plus low per-transaction charges.

You get that savings through wholesale interchange rates passed directly to you, which is especially useful if your average ticket size is high or you run a busy multi-lane store.

For in-store operations, you can use Clover or Vital Select POS systems that add inventory tracking, employee management, and reporting, so your payments and daily operations live in the same place.

If you’re already running compatible terminals, Payment Depot can often reprogram that hardware, letting you cut fees without ripping out your current setup. Month-to-month terms and no long contracts give you room to switch if the numbers ever stop working in your favor.

Payment Depot Key Features

Beyond pricing and POS flexibility, Payment Depot includes a few practical tools retailers will lean on day-to-day.

• ACH And eCheck Acceptance: Add lower-cost bank payment options for B2B customers and large invoices.
• Reporting And Deposits Dashboard: Monitor batches, deposits, and chargebacks from a single portal to simplify reconciliation.
• Recurring Billing And Invoicing: Support automatic recurring charges and invoice-based payments through connected gateways for memberships and service plans.
• Equipment Catalog And Reprogramming: Access a wide range of compatible terminals and card readers, or have many existing devices reprogrammed to work with Payment Depot.

Payment Depot Integrations

Integrations include Clover POS, SwipeSimple, Vital Select, Authorize.Net, Shopify, WooCommerce, BigCommerce, PrestaShop, OpenCart, and Revel Systems.

KORONA POS is built for retailers and venues that live and die by inventory accuracy—multi-location shops, liquor stores, museums, amusement parks, and other high-volume operators.

You get real-time stock control, ticketing, and a configurable checkout that can keep up with long lines, franchise rules, and staff who don’t have time to fight their POS.

Why I Picked KORONA POS

I picked KORONA POS because it gives you real-time inventory across multiple locations, backed by tools like automated reordering, stock thresholds, and detailed product reporting so you can actually trust your on-hand counts.

You can sell tickets, passes, and admissions directly through the same POS, using built-in ticketing and access controls to handle timed entries and events without a separate system.

Your team can work faster at the register with barcode scanning, customizable layouts, and offline mode that keeps transactions flowing even if the internet drops. I also like that you can set granular user permissions and role-based access, so managers get full reporting while cashiers see only what they need to do their jobs.

Pricing starts at a flat rate per terminal with an unlimited free trial, which makes it approachable for growing retailers who want enterprise-style inventory tools without a bespoke IT build.

KORONA POS Key Features

Beyond the core inventory tools, there are a few features that make KORONA POS especially useful for complex retail and ticketing environments.

• Franchise Management: Control pricing, products, and settings centrally while still allowing location-level overrides where it makes sense.
• Vendor Management: Create purchase orders, receive stock, and track vendor costs so your replenishment process isn’t stuck in spreadsheets.
• Hardware Flexibility: Run the system on standard POS terminals, tablets, scanners, receipt printers, and cash drawers instead of being locked into proprietary gear.
• Loss Prevention Tools: Use cashier permissions, void/refund controls, and audit logs to keep an eye on risky behavior and tighten shrink.

KORONA POS Integrations

Integrations include WooCommerce, QuickBooks Online, bLoyal, CMS Max, City Hive, TimeForge, mapAds, NearSt, and Octopus Bridge.

Shopify POS is built for ecommerce brands that want their in-store checkout, inventory, and customer data to live in the same system as their online shop.

You can sell at permanent locations, pop-ups, and events while keeping one product catalog, one order history, and one view of each customer.

It’s best for Shopify merchants who see physical retail as an extension of their online brand, not a separate channel.

Why I Picked Shopify POS

I picked Shopify POS because it gives you a single back end for both online and in-person sales, so your team doesn’t have to reconcile inventory or customer records across multiple systems.

You can offer omnichannel perks—like buy online, pick up in store or ship-from-store—through built-in workflows that tie directly into your Shopify orders and locations.

Store staff get role-based permissions and PIN logins, so you can protect refunds, discounts, and sensitive settings while still moving quickly at the counter.

I also like that Shopify POS runs on iOS and dedicated hardware, giving you a flexible setup for everything from mall kiosks to multi-location flagships. For ecommerce-first retailers, that combination of unified data plus flexible hardware makes it a natural upgrade path when you move offline.

Shopify POS Key Features

In addition to the unified back end, there are a few POS-specific tools that help ecommerce brands make brick-and-mortar actually work.

• Customer Profiles And Loyalty: Build unified profiles from in-store and online orders, then use purchase history and preferences to power targeted marketing and loyalty perks.
• Local Pickup And Delivery: Offer local pickup, ship-from-store, and local delivery options that pull from real-time store inventory instead of a separate warehouse system.
• Retail Analytics And Reports: Track store, staff, and product performance with location-based dashboards, helping you adjust staffing, merchandising, and promotions with live data.
• App Store Extensions: Tap into the Shopify App Store for retail-focused add-ons—like staff scheduling, loyalty programs, and clienteling—without replacing your core POS.

Shopify POS Integrations

Integrations include Mailchimp, Klaviyo, QuickBooks Online, Xero, ShipStation, Etsy, SKU IQ, ShipHero, and HubSpot.

For restaurant owners who want a POS that actually fits how their kitchen and front-of-house run, Lavu gives you a lot of control over menus, modifiers, and pricing.

It’s built for full-service and quick-service restaurants that care about things like recipe costing, server performance, and card fees—not just ringing in tickets.

Lavu is best for operators who are willing to invest a bit more in exchange for customization and deeper control over their numbers.

Why I Picked Lavu

I picked Lavu because you can mold it around your concept instead of forcing your concept into a rigid POS template. You can customize menus, modifiers, and service types, so your team can handle things like split checks, coursing, and complex item builds without workarounds.

Lavu’s open API and menu of add-ons—like online ordering, loyalty, and back-office tools—let you plug it into the rest of your stack as you grow.

You also get detailed sales and labor reporting tied to items, categories, and staff, which helps you debug margins and staffing instead of guessing.

On the payments side, the cash discount and dual pricing programs give you a concrete way to offset card fees, which can be a big deal for high-volume restaurants with tight margins.

Lavu Key Features

Beyond customization, there are a few core tools that make Lavu practical for day-to-day restaurant work.

• Tableside Ordering And Payments: Let servers fire orders and take payments right at the table using iPads or mobile devices.
• Floor Plan Management: Build digital floor plans that match your actual layout so staff can track open tickets, table turns, and sections in real time.
• Customer Loyalty And Gift Cards: Run in-house loyalty programs and time-bound gift cards without a separate system, keeping rewards data tied to checks.
• Delivery And Takeout Management: Manage in-house delivery, takeout, and online orders from the same POS so you can track off-premise revenue alongside dine-in.

Lavu Integrations

Epos Now is built for busy retailers and hospitality operators who want an all-in-one POS and hardware stack they don’t have to cobble together piece by piece.

You get preconfigured bundles for tills, printers, scanners, and card readers, plus cloud-based software that tracks inventory, sales, and staff activity across locations.

It’s a strong fit if you want plug-and-play hardware with enough flexibility to add apps and delivery channels as you grow.

Why I Picked Epos Now

I picked Epos Now because its hardware bundles give you a ready-made checkout—touchscreen terminals, receipt printers, barcode scanners, and card readers are spec’d to work together from day one, so you’re not guessing about compatibility.

For inventory control, you get real-time stock tracking, purchase ordering, and low-stock alerts across locations, which helps you avoid walkouts due to stockouts.

Your team can access detailed sales and profit reports from any device, so you can spot bestsellers, slow movers, and margin issues without exporting spreadsheets. I also like that you can use Epos Now’s own payment service or plug in supported third-party processors, letting you optimize for rate structure or existing banking relationships.

Finally, its app store and delivery integrations let you connect accounting, ecommerce, loyalty, and food delivery platforms, so your POS actually matches the way you sell.

Epos Now Key Features

On top of the hardware bundles and core POS tools, Epos Now adds a few quality-of-life features your team will actually notice during a shift.

• Training Mode For Staff: Lets new team members practice real transactions in a sandbox environment, so they can learn workflows without messing up live data.
• Multi-Location Dashboards: Consolidates sales, inventory, and staff performance across sites into one view, helping you compare stores and reallocate stock or labor.
• Staff Management And Permissions: Assigns granular roles and login restrictions, so you can protect discounts, refunds, and reports while still moving queues quickly.
• Customer Loyalty And Promotions: Tracks purchase history and points while running targeted promos and discounts directly from the POS, instead of juggling separate loyalty tools.

Epos Now Integrations

Integrations include QuickBooks Online, Xero, Sage 50, Shopify, WooCommerce, BigCommerce, Mailchimp, Loyalzoo, Uber Eats, and Deliveroo.

Helcim is built for retailers and service businesses that care about every basis point of processing cost.

You get free POS software, transparent interchange-plus pricing with automatic volume discounts, and tools that keep in-person, online, and invoice payments under one roof—especially attractive once your monthly card volume starts to climb.

Why I Picked Helcim

I picked Helcim because its interchange-plus pricing with built-in volume discounts lets you keep a bigger share of each sale as your card volume grows.

You avoid monthly software fees because the POS, virtual terminal, invoicing, and online checkout tools are included with your merchant account, so your fixed costs stay low.

Your team can sell in-store with the Smart Terminal, on mobile with the POS app or Tap to Pay, and online through payment pages or checkout links, while everything syncs back into one dashboard.

I also like that you can configure user permissions, so cashiers, supervisors, and managers only see the parts of the system they actually need. For high-volume merchants that want transparent pricing plus serious flexibility in how they take payments, Helcim hits the sweet spot.

Helcim Key Features

Beyond pricing and basic POS, Helcim includes tools that support multi-location retailers and growing service businesses.

• Inventory And Product Management: Track stock levels, variants, and catalog updates across locations from a single back office.
• Customer Profiles And CRM: Store customer details, cards on file, and purchase history to speed up repeat sales and invoicing.
• Employee Permissions: Configure role-based access so staff can take payments while managers control discounts, refunds, and reports.
• Recurring Billing And Payment Plans: Set up subscriptions or scheduled invoices for retainers, memberships, or large-ticket payment plans.

Helcim Integrations

Integrations include QuickBooks Online, Xero, WooCommerce, Magento, Foxy.io, and Great Exposure.

Clover is built for small retailers and restaurants that want one vendor for payments, hardware, and day-to-day operations—not a Franken-stack of disconnected tools.

You get countertop and handheld devices, a built-in payments gateway, and an app marketplace that lets you plug in inventory, payroll, and marketing tools as you grow.

Why I Picked Clover

I picked Clover because it gives you an all-in-one POS, payments, and hardware stack that’s actually designed for busy small businesses, not IT departments.

You can mix and match devices—like Station Solo at the counter plus Flex on the floor—so your team takes payments wherever the customer is. Your deposits hit quickly via next-day funding or Rapid Deposit, which helps when you’re covering payroll or supplier invoices from card sales.

You also get built-in tools for staff roles and permissions, so cashiers, managers, and owners each see only what they need.

Finally, the Clover App Market lets you bolt on things like advanced inventory, payroll, or accounting, so your POS can grow alongside your store without a painful system swap.

Clover Key Features

On top of the core POS and payments stack, Clover adds a few very practical tools for small retailers and food-and-beverage operators.

• Inventory Management Tools: Track stock by item and variant, set low-stock alerts, and keep counts synced across devices and locations.
• Clover Online Store And Ordering: Spin up a basic online store or ordering page that connects directly to your Clover catalog and POS.
• Customer Loyalty And Promotions: Run points, punch-card style rewards, and targeted offers tied to customer profiles and purchase history.
• Reporting And Dashboards: Monitor real-time sales, taxes, and employee performance from the Clover web dashboard or mobile app.

Clover Integrations

Integrations include Time Clock by Homebase, Thrive Inventory, stockIt, Easy Labels, QuickBooks via Commerce Sync, Payroll by Gusto, Paychex Flex, and Kitchen Display by 4LeafLabs.

Merchant One is a good fit if you want direct credit card processing tied closely to your POS hardware, rather than going through an aggregator.

You get countertop terminals, Clover-based POS systems, and mobile readers under one merchant account, so you can keep in-person payments, online sales, and back-office reporting in the same ecosystem.

It’s best for small and midsize US businesses that care about fast funding and hands-on onboarding support.

Why I Picked Merchant One

I picked Merchant One because it gives you a true merchant account with next-day funding options, so card sales hit your bank faster through its direct acquiring relationships.

You can run traditional terminals, all-in-one Clover stations, and mobile readers, which helps your team cover fixed counters, line-busting, and off-site events without juggling different providers. Your account comes with tools like inventory and employee management through compatible POS systems, so you can track stock and staff performance directly from the register instead of wrestling with spreadsheets.

I also like that you can accept a wide range of payment types—EMV chip, tap-to-pay wallets, gift cards, and checks—on the same platform, backed by encryption, tokenization, and PCI-compliant processing.

For merchants with less-than-perfect credit or slightly higher risk profiles, Merchant One is more flexible on approvals than many big-bank processors, which opens the door for businesses that would otherwise be stuck on cash or clunky workarounds.

Merchant One Key Features

In addition to the direct processing relationship, Merchant One includes several day-to-day tools your team will actually use at the POS.

• Virtual Terminal: Run keyed-in, phone, or invoice payments from any browser-based workstation.
• Recurring Billing: Set up subscriptions or installment plans so repeat charges run automatically and predictably.
• Detailed Reporting: Monitor deposits, charge volume, refunds, and card types in a central dashboard for easier reconciliation.
• Chargeback Management Tools: Get alerts and supporting documentation options that help you respond to disputes more effectively.

Merchant One Integrations

Integrations include Authorize.net, Payeezy Gateway, Payflow Pro, Paytrace Gateway, USAePay, Aloha, Micros, and Maitre’D.
