If you run a pet store — or a grooming salon with a retail section — your point-of-sale system is the heartbeat of your operation. Every transaction, every inventory update, every customer interaction flows through it.
The good news: POS systems have gotten dramatically better and cheaper in the last few years. You don’t need to spend $5,000 on a legacy system anymore. A $49 card reader and a free app on your iPad can handle most pet store needs. We break this down further in How to Manage Pet Store Inventory Effectively.

Top POS Systems for Pet Stores
1. Square for Retail — Best Free Option
Software cost: $0 (Free plan) | $60/month (Plus) | Custom (Premium) Processing: 2.6% + $0.10 (in-person) Hardware: $49 (contactless reader) to $799 (Square Register)
Square for Retail is the easiest way to get a functional POS running in a pet store. The free plan includes everything a small store needs.
Free plan features:
- Unlimited products and categories
- Barcode scanning (via phone camera or Bluetooth scanner)
- Inventory tracking with low-stock alerts
- Customer directory with purchase history
- Basic sales reporting
- Cash management
- Receipt printing (via connected printer) or digital receipts
Plus plan ($60/month) adds:
- Automatic purchase orders
- Vendor management
- COGS (cost of goods sold) tracking
- Advanced inventory reports
- Barcode label printing
Why pet stores choose it:
- Free to start — no monthly commitment
- Dead simple to set up (seriously, 30 minutes)
- The ecosystem is clean — POS, payments, online store all integrated
- Hardware is affordable and reliable
Limitations:
- Inventory management is basic on the free plan
- No real purchase order system without the Plus plan
- Reporting is adequate but not deep
- Customer loyalty features are limited
2. Lightspeed Retail — Best for Serious Pet Stores
Price: $89/month (Basic) | $149/month (Standard) | $239/month (Advanced) Processing: Custom rates (typically 2.6% + $0.10)
Lightspeed is professional retail management. If you have 500+ products, multiple suppliers, and need sophisticated inventory control, this is your tool.
Key features for pet stores:
- Advanced inventory management — variants, bundles, kits, serialized items
- Purchase order management — create POs, send to suppliers, receive inventory, track shipments
- Vendor management — supplier catalog integration, automatic reorder points
- Multi-location inventory — transfer stock between locations
- Customer loyalty — point-based loyalty program built in
- Detailed analytics — product performance, inventory turn rates, gross margin reports
- E-commerce — integrated online store (Lightspeed eCom)
- Employee management — individual permissions, sales tracking
- Gift cards — physical and digital
Why established pet stores choose it:
- The inventory management is genuinely powerful
- Purchase orders streamline supplier relationships
- Reporting helps optimize product mix and pricing
- Multi-location support works well
Why small stores don’t need it:
- $89/month is significant for a small operation
- Lots of features you won’t use if you have under 200 products
- Setup takes longer than Square
- The complexity can be overwhelming
3. Shopify POS — Best for Omnichannel (In-Store + Online)
Price: $39/month (Basic Shopify) + $0 (POS Lite) or $89/month (POS Pro per location) Processing: 2.6% + $0.10 (in-person with Shopify Payments)
If you sell pet products both in your store and online, Shopify unifies everything. One inventory, one product catalog, synchronized across all channels. If you’re exploring this area, our Best Inventory Software for Pet Stores (2026) guide covers it in detail.
Why pet stores go omnichannel:
- Sell specialty products online to customers beyond your local area
- Offer “buy online, pick up in store”
- Capture sales from pet owners browsing at night
- Specialty items (raw diet foods, custom collars, breed-specific products) have online demand
4. Clover — Turnkey Hardware + Software
Price: $14.95/month (Starter) | $49.95/month (Standard) | $69.95/month (Advanced) Hardware: $599-$1,799 (Clover POS terminals)
Clover is popular because it comes with sleek hardware right out of the box. The register hardware looks professional and is purpose-built for retail.
The trade-off: The hardware is proprietary — you can only use Clover devices with Clover software. If you switch POS systems later, the hardware is useless. Square hardware is more affordable and the software is more flexible.
POS Setup for Pet Stores
Hardware Recommendations
Budget setup ($120-$300):
- iPad or Android tablet (you probably already have one)
- Square Reader for contactless + chip ($49)
- Cash drawer ($40-$80)
- Phone as barcode scanner
Standard setup ($400-$700):
- Dedicated iPad on a stand ($30-$100 for the stand)
- Square Reader ($49)
- Bluetooth barcode scanner ($80-$150)
- Receipt printer ($200-$300)
- Cash drawer ($40-$80)
Full setup ($800-$1,500):
- Square Register ($799) or iPad + Square Stand ($149)
- Barcode scanner ($80-$150)
- Receipt printer ($200-$300)
- Cash drawer ($40-$80)
- Label printer for barcode labels ($150-$300)
Product Setup Tips
- Use consistent naming: “Royal Canin Medium Adult 30lb” not “RC Med 30#”
- Create logical categories: Dog Food, Cat Food, Treats, Toys, Grooming Supplies, Health, Accessories
- Set up barcode scanning: Most pet products already have UPC barcodes. Scan them into your POS on initial setup.
- Track variants: Same product in different sizes should be one product with size variants, not separate products
- Set cost prices: Input what you pay for each product so the POS can calculate margins
- Set reorder points: Alert when stock drops below minimum levels
Loyalty Program Setup
Pet stores benefit enormously from loyalty programs because customers make repeat purchases (food, treats, supplies).
Simple points-based program:
- 1 point per $1 spent
- 100 points = $5 reward
- Bonus points on slow-moving products
- Birthday rewards for pets (yes, track pet birthdays)
Square, Lightspeed, and Shopify all offer loyalty program features.
Pet Store Revenue Optimization
Track Your Top Sellers
Your POS reporting shows which products generate the most revenue. Typically for pet stores:
- Dog food: 30-40% of revenue, lowest margin (10-20%)
- Cat food: 10-15% of revenue, low margin
- Treats: 10-15% of revenue, higher margin (30-50%)
- Toys: 10-15% of revenue, highest margin (40-60%)
- Grooming supplies: 5-10% of revenue, high margin (35-50%)
- Health products: 5-10% of revenue, medium margin (25-40%)
- Accessories: 5-10% of revenue, high margin (40-60%)
The insight: Food drives traffic (people need it regularly) but has low margins. Make your money on treats, toys, and accessories that people impulse-buy alongside food.
Optimize Your Product Mix
Use POS data to:
- Kill dead products — anything that hasn’t sold in 60 days, put on clearance and don’t reorder
- Expand winners — if a product consistently sells out, carry more sizes/variants
- Seasonal adjustments — flea/tick products in spring, coats in fall, holiday toys in November
- Test new products — small initial orders, track sales velocity, expand or drop based on data
My Recommendation
Small pet store or grooming salon with retail: Square for Retail (free). Covers everything you need to start.
Growing pet store (200+ products): Square for Retail Plus ($60/month) or Lightspeed Retail ($89/month). The inventory management upgrade is worth it at this scale.
Pet store with online sales: Shopify ($39/month + POS). Unified inventory across in-store and online.
Just want hardware that looks good: Clover ($14.95-$69.95/month + hardware). But know you’re locked into their ecosystem.
The bottom line: Your POS should make checkout fast, track inventory accurately, and give you data to make smart decisions. For most pet stores, Square’s free plan does this on day one.
