Custom Inventory
Management Systems

Whilst business is good out-front, what’s going on back of house? Are you truly on top of your inventory management?

Whether you’re managing complex inventory that off-the-shelf systems simply can’t handle, or you need a smarter stock management solution for your ecommerce business, we will build you something that helps you and your business flourish and fly.

If you’re relying on less-than-ideal technology to do the heavy lifting, it’s worth investing in a custom web application that can tie all of your products, integrations and stock together in one bespoke package.

Talk to us today about developing your custom web app.

Ideal for growing businesses

As your business grows, your stock does too. Product lines can become complex and if you have to handle serialisation it gets unwieldy. As a small business, it’s smart to implement an inventory management system early to futureproof your business. It’s better to design for growth than have to react because of it.

More cost-effective than an ERP

ERPs are expensive and can be a seemingly endless headache to implement. Save yourself money and time by investing in a solution fully tailored to your business. Our systems designers and technologists have worked on many successful implementations and we’ll be happy to talk to you about relevant examples.

Its simple and it fits

Off-the-shelf inventory management systems can be complicated, with many features being unnecessary and ending up unused. When we implement a custom solution for your business, it’s simple, straightforward and perfectly matches your requirements. Already invested in cloud-based software? We can integrate with that too.

"We were working in different systems and spreadsheets which was time consuming and data would get mixed up. The custom software OnlyExcel created has made a huge difference. Now I'm more focused on business strategy than daily tasks; I'm delegating more responsibility; things are getting done quicker and I'm even getting more time off and planning in some holidays!"
Founder, eCommerce Business
"We worked with OnlyExcel to create something bespoke for us. What we found was, quite simply, freedom - we could manage, report and work our way and not the systems way. Since that first creation, we have adapted and added, but we retain control over our project management and that has saved time and money and a lot of frustration."
