Month-end information in about a day, not three weeks.
As Mous expanded beyond phone cases into a larger direct-to-consumer business, disconnected accounting, inventory, shipping, and e-commerce applications created reporting and data-management bottlenecks. Acumatica centralized operational data, connected online stores, and gave the team faster access to financial and supply-chain information.

Company & challenges
Mous is a UK-based, direct-to-consumer business that began with durable phone cases and expanded into tech accessories.

It built demand through online channels, including Shopify stores and marketplaces. As order volume grew, its separate back-office applications became harder to manage.
Mous used Xero for accounting, multiple Shopify stores for sales, and ShipStation for shipping. Inventory, bills of materials, and related processes depended on spreadsheets or disconnected tools, making reporting and data reconciliation slow. To make matters worse, Xero and ShipStation often crashed.
Operations Director and co-founder James Day said the company lacked reliable visibility into inventory and product costs. Employees sometimes ordered parts that were already in stock, and large data exports could take a long time. Tax reporting across the EU, UK, and United States added to the manual work.
The solution
Mous considered several ERP options, including Microsoft Dynamics and Oracle NetSuite, before choosing Acumatica. Its evaluation included a proof of concept showing how thousands of Shopify orders could flow into Acumatica, along with a review of reporting and system fit.
“All of our data is now centralized in one place.”

The benefits

Centralized data and faster month-end information
Mous could follow purchasing, inventory transfers, warehouse receipts, shipments, and tracking data through connected records rather than reconciling disconnected applications. Day said month-end information was available roughly one day later instead of about three weeks later.
Inventory and commercial analysis
General Inquiry and other reporting tools gave the operations team access to cost-of-goods-sold information, inventory status, and e-commerce order data. Mous could compare SKUs, purchase behavior, markets, and shipping costs in more detail, without running its own servers or maintaining a dedicated data-engineering team.
Simpler changes to business processes
Acumatica is highly configurable and extensible, with low-code and no-code tools that Mous used to adapt workflows without rebuilding the core ERP. For product replacements, staff could connect a new request to the original order and respond through a simpler process with fewer screens and steps.
