What we build
Everything from websites to apps, made to order
From a single brochure page to a multi-user platform, from desktop software to bots running on Telegram and Zalo. Describe the problem and CMSNT proposes a solution that fits your budget.
02
Desktop software
Applications for Windows and macOS: AI tools, batch data processors and internal management software.
03
iOS & Android mobile apps
Apps for your customers or your team: ordering, loyalty points, task management, push notifications. Cross-platform development keeps costs down, and we help you publish to the App Store and Google Play.
04
Bots & automation tools
Telegram, Zalo and Discord bots; tools that collect data, schedule posts, handle customer care and send reminders automatically. Running 24/7 on a VPS to eliminate repetitive manual work.
05
API & payment integration
Connect your system to banks, MoMo, PayPal, USDT, e-commerce marketplaces, Google, OpenAI and other third-party APIs. Transactions are recorded automatically and data stays in sync both ways.
06
Upgrades & legacy maintenance
Fix bugs, speed things up, add features or rewrite old software that has become slow and hard to extend. We can take over code from another vendor after a review.
How we work
Five steps from idea to delivered product
Every project follows a clear process with a checkpoint at each stage, so you always know where things stand and what they cost.
- 01
Requirements intake
You describe the idea over Telegram, Zalo or a support ticket. CMSNT asks clarifying questions about goals, users, core features and the budget you have in mind.
- 02
Analysis & quote
We draft the feature list, recommend a tech stack, estimate the timeline and quote each item in detail. Free of charge and with no obligation.
- 03
Contract & deposit
The scope is locked in a contract and a VAT invoice is issued. Payment is split by milestone, usually with a 30 to 50% deposit to start.
- 04
Development & staged demos
We build milestone by milestone, and each one ships with a working demo for your feedback. Early adjustments mean no expensive rework later.
- 05
Handover & warranty
We deploy to your server or devices and hand over the source code, documentation and user guide. Bugs are fixed under warranty and we are on hand for future extensions.
Before you get in touch
The clearer the brief, the faster the quote
No technical knowledge needed. Answer the questions below and CMSNT can give you a preliminary quote within one to two working days.
Send your brief- 01Do you need a website, desktop software, a mobile app or a bot/tool?
- 02What is the product for and who are its main users?
- 03A list of the core features you need (bullet points are fine).
- 04Any existing websites or software you would like us to reference?
- 05Your estimated budget and preferred completion date.
- 06Do you already have a domain, server or developer accounts?
Why CMSNT
Work directly with the team behind real products
CMSNT is not a broker. We build and operate products used by thousands of customers, so we know what actually works in production.
01
Experience from products on the market
CASHBACK, SHOPKEY, CRONJOB, ChatHub and I2V Studio were all written and maintained by CMSNT for years. That experience goes straight into your project.
02
Complete source code handover
You own the entire source code, database and documentation once payment is complete. No lock-in, no hidden retainer, and you are free to keep developing it.
03
Contract and VAT invoice
A registered business with a tax ID, we sign a contract and issue a full VAT invoice for every project. Scope and cost are written down before work starts.
04
Direct communication, fast replies
You speak directly with the people building your product over Telegram or Zalo, not through layers of account managers.
05
Automation first
Every system is designed to run by itself: payments recorded, orders processed and notifications sent without manual approval.
06
Warranty and long-term support
Free bug fixes during the warranty period, plus technical support and further upgrades as your business grows.
