Pet Store POS System – One Platform for POS, eCommerce, and Inventory

If you run a pet store, you know a POS system has to do more than just process transactions — it needs to help you stay organized, sell online, and make your day easier.
That’s exactly what PetStack does.
PetStack is a pet store POS system built specifically for independent pet retailers. It brings POS, eCommerce, inventory, and loyalty together in one platform, so everything works off the same data and stays in sync — without you having to manage multiple systems.
If you’re an indie pet store owner, you’re in the right place.

What Pet Stores Really Need from a POS Today
Not that long ago, a POS system was just a register. You rang up a sale, closed the drawer, and moved on.
Today, it’s different. Your POS sits at the center of your business. It affects inventory accuracy, online sales, ordering, reporting, and how confident you feel running your store day to day.
When someone searches for a pet store POS system, they’re usually trying to solve a problem with questions like: Why doesn’t my inventory ever match? Why is selling online such a headache? Why does everything feel harder as we grow?
A modern pet store POS system should answer those questions — not create new ones.
Why We Built PetStack
PetStack is built for independent pet retailers who feel stuck between two bad options: generic retail POS systems that don’t understand pet stores, or enterprise software that’s way more complex than most independent stores need.
We took a different approach.
PetStack was made to be one unified system from the start. POS, inventory, eCommerce, loyalty, and more all live on the same platform, sharing the same data in real time. That means no syncing issues, no double work, and no wondering which numbers are right.
It’s software that’s meant to support how pet stores actually operate — not force you to work around it.
One System Instead of Many
One of the biggest problems we see in pet retail is fragmentation. POS in one system, inventory tracked somewhere else, and eCommerce bolted on as a separate tool.
With PetStack, everything starts from the same source of truth.
When you sell something in-store, inventory updates immediately. When a customer places an order online, it pulls from that same inventory. Because everything is connected, you get a clearer picture of what’s selling, what’s slowing down, and what needs to be reordered.
The result isn’t just better data — it’s less stress. Fewer surprises. Fewer end-of-day or end-of-month fixes.
Selling Online with a Custom Webstore
One of the most common concerns we hear from small pet stores is, “We don’t even have a website. Are we ready for eCommerce?”
PetStack Plus makes selling online simple by hosting your webstore.
There’s no separate platform to build, no inventory to manage in two places, and no technical lift just to get started. Your online store runs off the same system as your POS and inventory, so everything stays aligned from day one.
And selling online isn’t just about convenience — it’s about growth. Companies that implement strong omnichannel strategies, blending in-store and online sales, see nearly 180% more revenue growth than those that don’t, according to Capital One Research. That kind of growth isn’t reserved for big chains. Indie retailers can benefit from it too, especially when the system is simple and unified.

Who PetStack Is For
PetStack is built for indie pet retailers who want a system that works with them, not against them. If you run one store or a small group of stores, sell in-store and online (or want to), and are tired of juggling tools that don’t talk to each other, you’re exactly who PetStack was built for.
FieldStack for Larger Pet Retail Chains
If you’re running a larger or more complex pet retail operation, your needs may look a little different.
PetStack is built specifically for independent pet retailers who want their core systems — POS, inventory, and eCommerce — working together without added complexity. For larger pet retail chains with more advanced operational requirements and consultative needs, that’s where FieldStack comes in.
FieldStack supports multi-location retailers that need deeper control, stronger reporting, and systems that can scale as the business grows. It’s the platform trusted by established pet retailers like Hollywood Feed and The Natural Dog, both of which rely on FieldStack to support their in-store and online operations as they continue to expand. FieldStack’s Client Success team also provides personalized support and guidance to help stores get the most out of the platform and keep operations running smoothly.

Choosing the Right Pet Store POS System
At the end of the day, choosing a pet store POS system isn’t all about features. It’s about confidence.
Can you trust your inventory? Can you sell online without creating chaos? Can your system support where your business is going next?
PetStack is built to answer yes to all of that — with one unified platform designed specifically for independent pet retailers.
If you’re evaluating pet store POS systems, this is what a modern, unified approach looks like.
