Frequently Asked Questions

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. Compare the four services →

It depends on whether your current system needs to change. If you need a new system, or your current system must be rebuilt or extended, choose Custom Software. If you want to keep your systems as they are and let AI take over repetitive work, choose AI Solutions. Many businesses combine both, implementing them in sequence.

It depends on who runs the work. If the scope is fixed and you want DESOL to manage delivery at a fixed price, choose Project Outsourcing. If the scope will keep changing and your team will run the work day to day, choose Dedicated Teams. When a project ends and the work continues, the same engineers can stay on as a dedicated team.

Start with Custom Software. The free prototype and quote package helps you visualize your core business workflow, together with its scope and cost. If you prefer to have a complete design first, the Design Only package delivers the specification, UI design, and architecture; you can then continue with DESOL, move to Project Outsourcing, or hand it to any development team.

Dedicated Teams is suitable when your business has someone to coordinate the work day to day. Without a technical manager, you may choose Project Outsourcing if you have a specification, or Custom Software if you need DESOL to advise on and manage the entire implementation.

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.

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. See ways to 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.

Project timelines depend on scope. After the prototype or assessment, you receive a roadmap and a quote for each phase before work begins.

Dedicated Teams has a minimum term of 3 months. Fixed-scope projects do not require a long-term contract.

Each approval milestone lets you reassess or end the engagement, and you keep everything from completed, approved milestones. Projects need two weeks' notice; Dedicated Teams need one month's notice.

No. DESOL develops the missing functionality and integrates it with the software you already use, so you keep the systems that work well. How we complement your software →

DESOL does not develop native apps. Instead, we build responsive web applications that work well in both desktop and mobile browsers.

No. We leverage established AI models from leading providers and suitable open-source alternatives, selecting the best fit for each use case. This reduces development costs and minimizes vendor lock-in.

Results with insufficient confidence are flagged for staff review. Accuracy is validated on your data before go-live and monitored continuously afterward. The approval step is enabled by default, and your business decides when to switch it off. Actions involving payments or commitments to customers always require human approval.

Emails and digital documents such as PDF and Word files, in English, Japanese, or Vietnamese (one language per document). Scanned images, handwriting, multilingual documents, and Excel or CSV files are not yet supported.

Each workflow has a monthly fee based on its scope, covering operation, monitoring, and improvement; AI model costs are charged based on actual usage. Both are agreed before go-live.

Yes. You can start with a few engineers and later expand to a dedicated team or an offshore development center (ODC), while the engineers who already know your product continue as the team grows. When a Project Outsourcing engagement ends but development needs continue, both parties can transition to the Dedicated Teams model.

DESOL sends 3 matched profiles within 3 working days. After you interview and select a candidate, the engineer can start within approximately 2 weeks.

DESOL replaces the engineer free of charge within the first 30 days and coordinates the handover to minimize any impact on the project schedule.

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. Working with international clients →

You receive a weekly progress report, see a demo after each milestone or sprint, and are given access to the project management tools to track every item.

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.

Yes. DESOL hands over the complete source code, technical documentation, and operating guides so that another vendor can take over and continue development.

Both parties sign a non-disclosure agreement (NDA) before discussing details, and all engineers on the project are bound by confidentiality obligations. Access is granted by role and revoked when the project ends. For sample data used in demos, your business decides how long DESOL retains it. See our security practices →

No. DESOL uses AI services that are committed to not training on customer data, running in your cloud account or on on-premise servers. How we keep AI safe →

Every delivery includes a 3-month warranty. After the warranty period, you may choose monthly operation services or continue working with the team that already knows your product.

You report the issue through the agreed support channel. DESOL responds within 4 working hours for critical incidents and within 1 working day for others, with a root-cause report and a remediation plan.
