Square is usually the first POS name you hear. A free plan, fast setup, and sleek hardware make it an easy place to start.
eTailPet is less familiar, but it was built for exactly the store you run — an independent pet shop where Astro Loyalty, grooming schedules, and a 160,000+ product catalog are part of every day.
Here's what the comparison actually looks like for a pet store owner.

*The $750 setup fee covers data migration and configuration, and is rebated in full after you go live and process payments.
One is a general POS with a pet store use case. The other was built for pet retail and nothing else.
Square is a household name in payments. The free plan and fast setup make it appealing for anyone opening a small business.
But it's a general platform serving coffee shops, clothing stores, restaurants, and pet retail.
Grooming scheduling, Astro Loyalty, a shared product catalog, and pet-specific workflows, such as vendor credits for recalled or expired stock, aren't part of the system.
Owners tend to describe Square as something that "works well enough" — until they notice how much manual work a pet-specific system would handle for them.
eTailPet takes the opposite approach: pet stores only. Astro syncs automatically at the register.
A 160,000+ product catalog comes pre-loaded with manufacturer pricing and descriptions.
Grooming and service booking are wired into the POS, and pet-specific workflows — vendor credits, special orders with customer notifications, formats like buy 12 get 1 — come standard.
Square sells its own hardware: the Reader for contactless and chip (2nd gen) at $59; the Stand at $149; the Terminal at $299; and the Register at $799, standalone or $1,339 for the full kit.
Some third-party hardware works, but the ecosystem runs best on Square's own devices.
The free plan is the draw for new businesses, covering basic transactions with limited features.
Square for Retail Plus runs $49/month per location (down from $89 in early 2025) and adds inventory and reporting.
Premium is $149/month per location.
The real cost is in add-ons: Loyalty at $45/month per location, Marketing at $15–$195/month, and Payroll at $35/month plus $ 6 per employee.
Free plan: 2.6% + $0.15 in-person, 3.3% + $0.30 online (online rose from 2.9% on January 13, 2026).
Plus and Premium: 2.4% + $0.15 in-person, 2.9% + $0.30 online. Keyed transactions are 3.5% + $0.15.
No long-term contracts — a genuine advantage. But flat-rate processing means a high-volume pet store pays the same rate whether it's running $10,000 or $100,000 in monthly card sales.
eTailPet is not a hardware provider — you can use hardware you already have.
Compatible hardware is listed on our site, and we recommend purchasing through our premier vendor, POS Guys, for hardware service and support.
Startup at $99/month covers POS, native website, e-commerce with synced inventory, the 160,000+ vendor catalog, unlimited phone and email support, unlimited users and products, basic reports, customer invoicing, and special order tracking.
Core adds grooming scheduling, Astro Loyalty auto-sync, QuickBooks, recipe builder, and promotional tools.
Plus adds multi-location, memberships, in-house loyalty, SMS receipts, commission tracking, and integrations with TaxJar, MailChimp, and Pointy by Google. Core and Plus pricing requires a sales conversation.
eTailPet Payments is included on all plans and is the only supported option. Flat pricing with competitive rates.
There's no $400/month surcharge, but no third-party flexibility either. Rates are described as "competitive flat pricing." Same-day funding (including weekends and holidays) is included.
Square's free plan sounds great until you add what a pet store actually needs. Most owners land on Square for Retail Plus at $49/month per location, and from there the add-ons stack:
Loyalty program: $45/month per location
Marketing tools: $15–$195/month
Payroll: $35/month + $6/employee
A basic setup (Retail Plus + Loyalty) hits $94/month per location. Add marketing and you're past $109/month — and that's before any appointment-scheduling or expiration-tracking apps owners bolt on through third parties.
The catch is that the features a pet store needs most — Astro Loyalty, grooming scheduling, the product catalog, vendor credits — aren't add-ons. They don't exist on Square at any price.
eTailPet's Startup plan is $99/month with the catalog, e-commerce, native website, and unlimited support included. Core adds Astro Loyalty and grooming, priced through sales. No app-marketplace subscriptions, no feature-by-feature add-on creep.

This is the one owners ask about first.
Square doesn't integrate with Astro at all — its own loyalty program is a $45/month add-on and a general points system. If your store runs on Astro, that means managing rewards entirely outside your POS, entering transactions twice.
eTailPet syncs Astro at the register on the Core plan, so a customer's balance updates without anyone touching a second system.
Square gives you a product library, but every SKU goes in by hand or via CSV, and you maintain it as vendors change pricing.
eTailPet ships with 160,000+ pet products already loaded — priced and described by the manufacturers, growing as vendors add stock.
For a store carrying thousands of SKUs across food, treats, toys, and supplements, that's days of data entry you skip.
Square has no integrated grooming. Square Appointments exists, but it's built for salons, not grooming tied to retail — and booking multiple pets from one household means creating duplicate services, so a family ends up making three separate appointments.
eTailPet books grooming inside the POS on Core, handles multi-pet families in a single transaction with different groomers assigned at once, and auto-fills cancellations from the waitlist.
Expired food, recalls, and vendor defects are routine in pet retail. Square runs them through the same return flow as any product, with no vendor-credit handling — so recalled stock can land back on the shelf.
eTailPet has a dedicated workflow that processes the credit without restocking what shouldn't be sold.
Switching POS systems can feel overwhelming. The right support shortens the learning curve and gets you back to selling faster.
Setup is fast — you can take your first payment in minutes.
But "up and running" for a basic retail counter isn't the same as "up and running" for a pet store with grooming appointments, a vendor catalog, Astro, and specialty product handling. Inventory setup is entirely self-service: CSV imports are available, but configuring categories, vendor relationships, and promotions is on you.
Support also thins out the less you pay. Free-plan phone support lasts 90 days, after which free users get an AI chatbot.
Plus-plan phone support runs Monday–Friday, 6 am–6 pm; 24/7 phone support is reserved for Premium or specific hardware and Restaurants subscriptions.
And the team supports all kinds of Square merchants, from food trucks to fitness studios, so pet-specific expertise isn't a given.
eTailPet runs the migration and setup directly.
The $750 fee (rebated once you go live) covers importing your inventory, configuring the catalog, setting up grooming, connecting Astro, and training your staff.
Phone and email support is included on every plan — no tiered cutoff.
For owners coming from Square, the difference is in who does the work. Instead of figuring out CSV formats and category structures yourself, eTailPet's team — people who set up pet stores every day — handles the technical side while you keep running the store.
Square is the easiest POS to get started with. eTailPet is the one built for pet stores.
The only way to know if a POS works for your store is to see it handle your products, your grooming schedule, and your day-to-day.
Square can handle basic pet store transactions, but it wasn't built for pet retail. Astro Loyalty, grooming scheduling, a shared product catalog, vendor credits, and special order tracking aren't available on any plan or at any price.
eTailPet includes all of them, starting on the Startup plan.
No. Square has its own loyalty program as a $45/month add-on, but it doesn't connect to Astro — so a store running Astro manages rewards entirely outside the POS.
eTailPet auto-syncs with Astro at the register on the Core plan.
The free plan covers basic transactions, but most pet stores need Retail Plus at $49/month per location, and add-ons stack from there — Loyalty ($45), Marketing ($15–$195), Payroll ($35 + $6/employee) — past $150/month without any pet-specific features.
eTailPet starts at $99/month with the catalog, grooming (Core), and Astro (Core) included.
The software is free for basic features, but you still pay 2.6% + $0.15 on every in-person card transaction (3.3% + $0.30 online, after the January 13, 2026, increase).
Plus and Premium drop the in-person rate to 2.4% + $0.15. On $15,000/month in card sales, processing alone runs several hundred dollars a month before you add Retail Plus, loyalty, marketing, or payroll — so "free" covers the software, not the cost of running on it.
eTailPet supports bring-your-own-hardware per their FAQ and recommends POS Guys as its preferred vendor.
Some peripherals may carry over, but the core Square Register and Terminal are built for Square's ecosystem and are unlikely to work elsewhere.
