Are you considering an open-source Point Of sales (POS) for your retail business but unsure which one to choose? Don't fret. We've put together this blog to make things a tad easy for you. 

But before we jump in, first things first:

What is an open source POS?

Open Source POS plays a vital role in helping retail shops and restaurants improve how they serve customers. It is one of those tools a business can't function well without. If you are one of those business owners not familiar with POS, you're not alone. Many people still confuse POS with PO, which is a purchase order. But POS and PO are totally different. 

POS stands for Point of Service or Point of Sale, and it is a system any retailer can use for a multitude of things. What about open source? Well, open-source refers to any solution that is free to any entrepreneur or individual to use, access the source code, and modify it.

Why using POS matters

Adopting an open-source POS system has many benefits to businesses. First, it offers your company a system that does more than tracking stock. You can use it to improve your customer service and put your restaurant or retail business back on an even keel, regardless of what type or size of your retail store. 

You can use a POS system to resolve your everyday issues and develop a new strategy that will give you a competitive edge. 

Example: Josh is the owner of Baby City, a retail store that sells baby products. Before adopting a POS solution, his team had to grapple with challenges such as inaccurate tallies, wrong sales records, and unrecorded sales. So Josh and his team had to spend time rectifying those errors. But one day his manager Kyra suggested that they try Odoo POS. Things started to improve significantly from then.  They can now record data and see how Baby City is growing. 

The benefits of using open source POS

  • An open-source POS lets you track your inventory and create order lists.
  • POS allows you to save data on the cloud and access information anytime or anywhere. 
  • An open-source POS works better than a manual register. In that, it records even transactions in real-time. 
  • It lets you track your inventory and create a list of available items for your customers. 
  • Information is at your fingertips. All it takes is logging in, then you download reports and share them with team members.
  • You don't have to employ a filing assistant; POS software stores everything on the cloud. 
  • Using an open-source POS solution allows you to measure the performance of your sales team. You will know who is less performing and incentivize those who are bringing in more sales. 
  • You will be able to monitor stock levels and know when to replenish your stock. 
  • Using POS software will save you time and money. Thanks to the speed of POS systems, processing transactions is now ten times faster for businesses.

Last but not least, we know that growing small retail or restaurants is no easy feat. That it takes more than dedication and determination. We know that business owners need to have more than just the right team. That without all the right tools at your disposal it's impossible to grow a business. That without an open-source you can't serve customers better than your competitors.

Indeed, the open-source POS will always be the lifeblood of the retail or restaurant business. But it is also true that your restaurant or bar is not the same as any other in your city or town. What does that mean? It means you will only benefit from one of those solutions mentioned above if you know which one to choose. As a business owner, you need a system that will help you manage purchases, cash flow, and inventory simultaneously.

A challenge that most business owners face is choosing the right tool that helps their business. Those that try to pick up a tool themselves will either end up replacing it with another wrong one. Or continue using a one-sided solution that doesn't help them. While there are many open-source solutions out there, it will save you time and money if you hire a professional.  

Example: When you run a small pizzeria, you may benefit from a solution like SambaPOS. You can use it to track your deliveries and monitor the performance of your pizzeria. If there is a specific popular pizza on your menu, Samba POS allows you to know which days of the month people tend to buy it. This way, your team will be able to know how many pizzas they should make. The fact that you can access it on both Android and iPhone makes it a must-have open-source software. 

Every retail or restaurant business cannot function without having adequate. So, choosing an open-source POS solution that allows you to do that goes without saying. And if that system is user-friendly like Odoo POS, that would be beneficial. After all, you don't need a solution that will take days to set up and for more days for your team to start using. 

What we like most about Odoo POS is that it connects with other Odoo tools. For instance, you integrate it with Odoo inventory and other e-commerce solutions as well. If you want to market products, you also sync them with other sales and marketing tools. As you can, there is no limit to what you can do with Odoo POS. Unlike other standalone systems that will cost you thousands of dollars each year, Odoo is an open-plan, which means it's accessible to business owners like you!

Let's say you are out of stock. A few days later, you receive inventory, and you want to sell it right away. YOdoo POS scans items then update quantities on your systems. What will be on your system will be exactly what is available. No human errors, no embarrassments. And your customers don't have to wait for days on end before you can start selling products again.  

Open-source systems will only benefit you when you have an expert by your side—someone who can help you choose the right POS system and customize it. An expert who can help you to come up with a strategy of serving customers faster. And by an expert, we don't mean just anyone, but someone who has helped hundreds of small businesses to thrive.
