CTL Studio.
Software for teams
that work on site.
An independent software studio in Johor, Malaysia. Making OpenRoster and building custom software for businesses.
Our product
OpenRoster
People. Employment. Contracts.
Security guards, cleaners and other site staff are often managed with spreadsheets, chat groups and paper contracts. OpenRoster keeps each worker's records and documents, the clients and sites they go to, and the contracts they sign online in one place. It is in early access now, and rostering comes next.
Custom software
