For companies with highly specialized operations, standard software often creates more friction than value. Washburn POS faced exactly that challenge, until it embraced Odoo and reshaped it into a system that mirrors how its business actually works. By combining the core applications with deep customization, Washburn POS dramatically increased operational efficiency across repairs, inventory, warranties, shipping, and HR.

Located in Monticello, Minnesota, Washburn POS employs around 100 people and operates one of the largest retail equipment repair centers in its space. The company specializes in repairing POS systems, lane printers, self-checkout systems, scales, servers, network equipment, and virtually any other device used in retail environments.


Unlike businesses that sell standardized products, Washburn POS manages thousands of individual units moving through repair cycles, departments, warranty states, shipping scenarios, and customer-specific rules. Every unit has a history, a serial number, and a unique operational path, which makes rigid software a poor fit.

Founded in the mid-1990s, Washburn POS grew long before modern ERP systems were designed to support service-heavy, repair-based businesses. That legacy shaped both the company’s strengths and its operational bottlenecks.


"We pretty much repair anything that plugs in. And if there’s something we can’t repair, we’ll figure it out."

Before Odoo:  Fragmented Systems and Manual Work




Before Odoo, Washburn POS relied on Fishbowl for inventory and a custom in-house repair system. Once repaired units left the technician area, employees manually entered information into spreadsheets and then transferred it again into the inventory system, duplicating work and increasing the likelihood of errors.

System stability was another issue. Fishbowl crashed frequently, sometimes requiring database restarts every five minutes, which disrupted workflows and slowed down operations across departments.

While other software options were considered over time, none could handle Washburn POS’s repair flows, specific rules, and serial-number-driven processes without extensive compromises.


"At the end of the day, people were doing data entry all the time. Nothing was connected.”

Rewriting the 
Rules With Odoo



Pete had been familiar with Odoo since version 8, when it was still known as OpenERP. When he joined Washburn POS four years ago, it quickly became clear that incremental improvements wouldn’t solve the company’s deeper operational problems. Within two months, he decided to switch:


"We need to move to something more stable ASAP. If it doesn’t work, we’ll make it work, because it’s open source."

Washburn POS started with core Odoo apps: Sales, Inventory, Contacts, Project, Employees, and Barcode. Project became the foundation for managing repair workflows, while Inventory and Barcode supported physical movement and traceability across the facility.

From there, customization accelerated rapidly. Today, Washburn POS runs around 700 MB of custom code on top of Odoo, nearly half the size of Odoo’s base code. Because of this scale of customization, the company remains on Odoo 15 and operates in a self-hosted cloud environment with its own cluster, with redundancy, load balancing, and failover techniques, maintaining full control over performance, logic, and data.

From Chaos to Control: The Real Impact of Odoo

The most transformative impact of Odoo at Washburn POS is not a single feature, but the ability to translate real-world operations into enforced system logic:

 Inventory management is a clear example.
In standard systems, barcode-driven inventory moves can create negative stock lines if users scan the wrong origin location. While mathematically correct, those negative lines caused confusion, questions from management, and wasted time. Pete customized Odoo to reflect how inventory actually behaves in the physical world, preventing misleading data and eliminating unnecessary investigations.

 Shipping workflows were completely rebuilt. Standard FedEx and UPS integrations didn’t work for Washburn POS because shipping charges were not financially accurate. Pete created a custom shipping system where users enter box dimensions and weight, generate labels, and manage multiple boxes per outbound shipment. Tracking numbers and shipping costs automatically flow back to the sales order line by line, making it easy to answer customer questions like, “What was this shipping charge for?”


 Customer interaction also shifted dramatically.
Washburn POS uses Odoo Portal and eCommerce not to sell products, but to manage repair intake. Customers can see only the equipment Washburn repairs for them, based on predefined rules and specific price lists. This prevents sales errors and moves order creation directly to customers, reducing internal workload and improving data accuracy.

 Warranty handling became one of the most powerful custom workflows. Warranties are tracked by serial number, not just by sales order. Customers can submit warranty repair requests through the portal by entering a serial number. If the warranty has expired, the system does not allow selection, preventing disputes before they happen. If a unit is under warranty but shows misuse (such as grease-damaged kitchen equipment), the system voids the warranty and automatically creates a new paid sales order, ensuring consistent enforcement of policy. 

 Operational enforcement is a recurring theme.
Instead of relying on training alone, Pete embedded rules directly into the system. Today, Washburn POS has caught around 90% of daily user errors before they happen, using validations, pop-ups, and personalized error messages that prevent incorrect actions entirely.

The cumulative efficiency gain is substantial. Pete describes the company’s operational maturity before Odoo as 2 out of 10. Today, it stands at 9 out of 10, driven by automation, reduced manual work, fewer errors, and systems that align with real workflows.

"The main advantage of Odoo is that it’s open source. Then automation. And honestly, once you understand it, it’s easy to learn."

What’s Next for Washburn POS


The evolution continues. Washburn POS recently replaced ADP with Paychex, and Pete built a custom Paychex Bridge inside Odoo. The system pulls attendance data directly from Odoo, applies company-specific payroll rules, manages PTO limits of 42 hours, reallocates excess hours automatically, and allows HR to revert entries when mistakes occur.

Attendance, payroll, warranties, repairs, shipping: every operational layer is connected. And development doesn’t stop. “I put together new stuff every day,” he adds.

Washburn POS proves that when flexibility matters, Odoo can become far more than an ERP, but can become the operational backbone of a highly specialized business. If your business is ready to move beyond workarounds and unlock the full potential of an open, adaptable ERP, Odoo can help you get there.
