Why a modern OMS pays for itself in the first year

Retailers know that investing in new systems can be hard to justify, but not when the return is this clear

Modern retail is fast-moving, margin-sensitive and operationally complex. With so many moving parts, it’s easy to see why some teams hesitate to overhaul their infrastructure. But the reality is, a true Order Management System (OMS) like OIL doesn’t just streamline operations, it delivers measurable savings and revenue protection within the first year.

Where the savings show up fast

Fewer errors: Automated payment validation, order routing, and refund logic dramatically reduce manual mistakes and their hidden costs.
Faster fulfilment: Smart sourcing and stock visibility ensure quicker, cheaper fulfilment from optimal locations.
Lower returns overhead: Automated workflows cut down on time, headcount and lag in refund processing.
Higher conversion rates: Accurate delivery promises, better availability and consistent service drive more checkouts—and fewer abandoned carts.

How to calculate ROI on an OMS

Revenue protection
Avoid lost sales from stockouts, failed payments, or delayed fulfilment. A good OMS increases order success rates and protects your revenue stream.
Operational cost savings
Reduce manual interventions, double-handling, customer service tickets, and return processing times. This frees up internal resources and cuts service costs.
Customer lifetime value
Winning over a new customer often costs far more than keeping the ones you already have. Mistakes in fulfilment, refunds, or communication can result in lost loyalty—and lost long-term value.
Efficiency and scalability
How many hours per week do your teams spend on tasks that could be automated? An OMS shifts your business from reactive to proactive, making scale possible without growing headcount.

Cost avoidance: How many mistakes, delays or returns does your team manually resolve each week?

Time saved: What’s the opportunity cost of your ops team doing manual work instead of strategic tasks?

Revenue uplift: What’s the impact of faster delivery, real-time stock and higher order success?

A modern OMS doesn’t just reduce cost. It unlocks efficiency.

A true OMS like OIL won’t sit quietly in the background, it will pay for itself. And quickly. By freeing up colleague time, improving visibility and reducing friction in every order, the ROI is both immediate and compounding. Importantly, OIL isn’t the most expensive option on the market. It’s designed to deliver enterprise-grade impact without the enterprise-sized price tag, ideal for retailers looking to maximise value from day one.
