Custom software development for Opera 3 and Dynamics 365

Custom software development is what Diskel does when off-the-shelf Pegasus Opera 3 or Microsoft Dynamics 365 doesn’t quite fit, from automating workflows to building integrations between the two systems. Whether you’re solving a specific challenge or streamlining a wider process, our solutions are built to fit your business, not the other way around.

Manual invoice entry. Paper trails you can't find at audit time. Purchase approvals stuck in someone's inbox. These are the everyday costs of running Pegasus Opera 3 without automation — and they add up fast. AutoInvoicing, AutoFiling and AutoApprovals each work as a stand-alone add-on for Opera 3, built and supported by Diskel as a Pegasus Authorised Developer. Buy the one that solves your problem, or use them together to automate your whole invoice-to-payment workflow.

Custom Opera 3 and Dynamics 365 reports

Data pulled out in the shape it's actually needed, not the system's default layout.
