Three characters, .net, X-to-Y. O2D reads most naturally as order to delivery, which is the single most measured process in commerce.
Order-to-delivery time is a headline metric for retailers, manufacturers, and logistics providers. It’s on dashboards, in quarterly reports, and in every supply chain software pitch. A company selling into that world gets a name that names the exact thing its customers are trying to improve.
Other readings work too: offline to digital, which describes a large category of transformation consulting, and observation to decision, which fits analytics and intelligence tooling.
The .net has a particular fit for logistics and supply chain, where the buyers are operational rather than consumer and the extension carries no penalty at all. What matters is that the address is short enough to print on a shipping label and say over a warehouse radio.
Three characters, established convention, fixed supply.
