Buying and selling used cars
Doa holds a secondhand dealer licence (kobutsusho kyoka) and is a member of AUTOSERVER, buying and selling used cars at dealer auctions. Get in touch whether you're looking for a car or want to sell one.
The licence number is on the company page.
Vehicle registration
Help with vehicle registration and notifications in Japan, such as cargo (commercial vehicle) registration. If you'd rather do the paperwork yourself, Doa's own service Todoroku builds it from the vehicle inspection certificate.
Own services
Built in-house, and run and supported by Doa.
-
Todoroku
Vehicle ledgers and registration paperwork. Enter the fields from the vehicle inspection certificate once, and it keeps the inspection, compulsory insurance and tax deadlines, the cost and profit per car (with consumption tax categories), and the steps from purchase through cargo registration to sale in one place. It also prints the weight distribution sheet for structural modifications. It's a tool for people who do their own paperwork; it doesn't file on anyone's behalf.
-
worklog
Works out each day's start, end, breaks and working time from the API logs of Slack, GitHub, GitLab, Backlog, Jira, OpenProject and Redmine. There's no agent to install, and it can build timesheets for past months.
