p4e.net
Payments remains the rare software market where incumbents are enormous and new entrants keep succeeding anyway, because the problem fragments by country, by currency, by regulator and by vertical faster than anyone can consolidate it.
P4E reads as payments for ecommerce, which names one of those fragments directly. It also carries platform for enterprise and power for everyone, the last of which suits energy access work.
The extension is unremarkable in any of those contexts. Payment infrastructure, platform businesses and technical services all sit on .net without a buyer noticing, while it keeps three characters within reach.
Short addresses accumulate value through use rather than through display. Invoices, API endpoints, support portals, email domains and documentation all carry the name thousands of times.
