My partner and I run a business in Manchester renting out camera lighting, and audio gear to film and event productions. For two years, we've been running an off-the-shelf open-source rental platform on our own local server. The initial setup and core configuration were handled by an external developer for 4,500 pounds which we split equally from the business account.
Over the past year however, another 12,000 pounds was spent developing custom booking logic, security deposit tracking and barcode inventory modules—all driven and managed purely by my own efforts. My partner's take is: "This software is open source anyway, no one owns the code, we'll write off the costs as operating expenses, and if we split, we can both just take a copy and use it." I argue that these custom builds and the database schema carry distinct IP value within the company.
How should development costs be divided for custom software built on top of an open-source core? In the event of a partnership split, who legally owns the customer database the custom modules, and the system license?
