Which service is right for my business?
Start with two questions. First, do you already know exactly what needs to be built? If not, DESOL will recommend a solution: choose Custom Software if you need to build or change a system, or AI Solutions if you want to keep your current system and let AI take over repetitive work. Second, if you already have a specification or backlog, who will coordinate the work day to day? If DESOL coordinates a fixed scope, choose Project Outsourcing. If your own team coordinates the work, choose Dedicated Teams.
How is the cost calculated?
Projects are quoted per phase, based on the required roles and corresponding rates, and the price is agreed before work begins. For Dedicated Teams, fees are billed monthly per engineer according to role and seniority, starting at $12 per hour. Any work outside the agreed scope is quoted hourly and requires your approval before it begins.
Are the prototype, system assessment, and AI consultation free of charge?
Yes. You receive the prototype, the reviewed specification and quote, the assessment report, or the AI demo before deciding to proceed, with no obligation to engage further. If you need a complete design package to use with any development team, you may choose the Design Only package.
How quickly can we start?
Software prototypes take 5–7 working days, a specification review and fixed quote 2 weeks, engineer profiles 3 working days, and AI demos 5 working days.
Who owns the source code and documentation after handover?
Once payment is completed as agreed, your business owns the project’s source code, documentation, and data, and may operate or further develop the product independently.
Which languages and time zones does DESOL support?
Our team works in English, Japanese, and Vietnamese in the GMT+7 time zone, and arranges hours that overlap with your working day for meetings and demos.
