Custom Business Software Built in Vietnam

Software shaped to how your company actually runs, with the source code yours.

Scope

What you get

  • Sales, inventory, receivables, attendance and production — your process, not a template

  • Full source code, database and documentation handed over at acceptance

  • Integrates with Excel, REST APIs and the accounting package you already use

Off-the-shelf software asks your company to follow someone else's process. A few months in, the team quietly goes back to spreadsheets while the subscription keeps billing. Custom software works the other way around: we sit with your supervisors and map how the business actually runs — who signs a goods receipt, how credit terms are calculated, which columns the month-end report must contain — and only then start building.

The systems we build cover sales and inventory management, accounts receivable and payable, time attendance and payroll, production and order tracking, and internal tools that bridge whatever you already run. You receive the full source code and database, deployed on your own server or a cloud account in your name, with role-based access per department. Handover is followed by training and a warranty period for the details that only surface in real use, because the version people actually use is never quite the version on paper. On budget, what custom software actually costs explains how the number is built.

Questions

Frequently asked questions

Request a quote for this service
Is custom software more expensive than a SaaS subscription?

Upfront, yes; per user per month, no. For a team of 10 to 30 people using a system for years, custom usually costs less across two to three years. We build that comparison with your real numbers before you commit.

Can it integrate with the systems we already use?

In most cases yes — Excel import and export, REST APIs, or synchronization with the accounting package already in place. We verify each integration during the assessment phase, before a contract is signed.

What if we want to change vendors later?

You can. Source code, technical documentation and server administration are yours at acceptance, so your company is never locked to a single supplier, including us.
