Software development outsourcing to Vietnam: a buyer's guide to AI-augmented delivery

This guide is for founders, CTOs, product owners and operations leaders weighing a Vietnamese delivery partner for the first time, or replacing one that did not work out. Netbase is a Vietnamese consulting and software company, so we have an interest; the checklist works just as well for comparing us with anyone else.

Why companies choose Vietnam for software delivery

Buyers usually arrive with a capacity problem, not a geography preference: a roadmap the in-house team cannot deliver, or a hiring market that is too slow or too expensive. Vietnam enters the shortlist for four practical reasons.

• A working day that suits several markets. Vietnam runs on UTC+7 all year, with no daylight saving change. Its afternoon meets the European morning, most of its day overlaps East Asia and Australia, and handoffs with the Americas can run overnight.
• An established legal base for software IP. Vietnam's Law on Intellectual Property (Law No. 50/2005/QH11) covers copyright, patents, designs and trademarks, and the country has been a member of the Berne Convention since 2004 and of the WTO TRIPS Agreement since January 2007, according to WIPO. A good contract still matters, but it sits on familiar foundations.
• An emerging-market cost base. Engineering costs generally sit below those of the main Western hubs. The saving is real only when it buys senior reviewers and QA, not a larger unsupervised team.
• A mature services industry. Vietnamese companies have delivered web, commerce and SaaS work for overseas clients for years, with written specifications, sprint reviews and English documentation.

We give no market statistics here: salary surveys and rankings date quickly. Ask each vendor for their own evidence instead: delivered projects, client references and how long their teams stay together.

What drives the cost of an outsourced team

The price per person is the most visible number and the least useful one. What you pay for is working software, and these drivers decide how much of it each month buys.

Netbase does not publish rate cards. A useful proposal turns your roadmap into a team shape, a timeline and a commercial model, so you compare vendors on the cost of an outcome rather than a day rate. Someone on your side must also own product decisions and answer questions within a day; without that person, no vendor model saves the budget.

Team models and commercial terms

Netbase offers four ways to engage: dedicated development teams, project-based development, on-demand support and fully managed delivery. Netbase leads with consulting, solutions and custom development, and delivers most projects on fixed-price contracts after discovery, with team models as a secondary option.

Commercial terms follow the model: a fixed price for a defined project, milestone payments for staged work, a monthly retainer for dedicated teams, or KPI-linked terms where outcomes can be measured. Onsite work is available on request at extra cost. Compare the two most common choices in dedicated team vs fixed price, or see how Netbase staffs and governs dedicated development teams.

Team shape. A delivery team at Netbase ranges from 3 to 30 people and combines business analysts, project managers, solution architects, developers, QA engineers and UI/UX designers. Work typically starts within one to two weeks after discovery.

AI-augmented delivery: what to expect from an outsourced team

Engineers now use AI assistants to draft code, tests and documentation, and buyers increasingly want AI features in the product itself. Neither is a reason to skip governance.

In how the team works. Expect AI help with code review, test drafts, documentation and grouping of bug reports. Each is a draft: an engineer reviews every suggestion, and the person who merges a change answers for it. Judge the team by accepted releases and defect trends, not by hours.

In what the team builds. Assistants over your documents, AI search, document capture and recommendations are now ordinary scope items. Ask for delivered examples. Netbase delivered a recommendation engine for 4over4, and has delivered retrieval-augmented knowledge assistants, document AI, MLOps pipelines, a WhatsApp AI chatbot and AI content moderation for clients it does not name.

Terms to agree in writing:

• Which AI tools and models may touch your code and data; Netbase chooses them per project rather than locking you to one vendor.
• Whether any code or data may leave your environment, and a commitment that it is not used to train third-party models.
• Human review before merge, licence checks on generated code, and who approves AI features that act on customers, prices or money.

Security by design. Code review, dependency scanning, secrets kept out of repositories and role-based access belong in the pipeline from the first sprint, not in a pre-launch fix.

Time-zone overlap and communication

Distance is rarely the problem in remote-first delivery; unmanaged time zones are. Decide in advance which hours both sides are online.

Whatever the overlap, name one owner on each side, end every day with a written handoff, and review progress weekly against a KPI dashboard. At Netbase, delivery communication runs in English over Slack, Zoom and client dashboards, with a dedicated account manager and project manager. The Hanoi head office works Monday to Saturday, 9:00 to 18:15 Vietnam time (UTC+7), with Sunday off; the overlap window is agreed in discovery.

Nearshore or offshore: Vietnam compared with Eastern Europe

For a buyer in Germany, Austria or Switzerland, the real alternative to Vietnam is usually a nearshore team in Poland, Romania or elsewhere in Central and Eastern Europe. Compare them on these factors rather than on day rates.

One German nearshore provider puts the extra correction effort on offshore projects at 10% to 30%. Treat that as a vendor's estimate, not a measurement, but take the point: an offshore team in Vietnam pays off when the scope is written down, reviewed weekly and handed over in writing; a nearshore team pays off when the work needs many live conversations a day or German-speaking engineers. For a long-running team, see how an AI-first offshore development center is set up and governed.

Intellectual property, contracts and data protection

A clear contract removes most of the IP risk. Separate three kinds of material.

At Netbase, the client owns the IP created in custom development; Netbase productized modules and Business Division products are licensed, not transferred. Protecting IP when outsourcing covers the clauses in depth. In practice:

• Keep the repository and cloud accounts in your own name from the first commit, with the vendor given role-based access.
• Sign NDAs with the company, and confirm that every contributor works under one.
• Agree a data processing agreement when the team will touch personal data; for EU or EEA data processed outside it, the European Commission's standard contractual clauses are the usual transfer mechanism.
• Plan the exit on day one: documentation, handover sessions and credential rotation.

Netbase security practice covers secure code review, TLS in transit and AES at rest, role-based access control, MFA for admin dashboards, vulnerability scanning, penetration testing and disaster recovery, with NDAs, DPAs and SLAs on request. Netbase also holds ISO 27001 certification and a SOC 2 Type II attestation; both cover Netbase's own operations, not your product or its hosting.

Risks and how to contain them

Most failures trace back to the first two rows; time spent in discovery turns the rest into routine governance.

How to evaluate a Vietnam software partner: the vendor checklist

Use these questions in your first calls. The first three are specific to a partner in Vietnam; the rest apply to any vendor. A vendor who answers them concretely, with names and examples, is worth a second meeting.

For the security row, security questions to ask a software development partner lists the evidence to request.

Turn the answers into a decision

Score every answer on this table from 0 to 2: a concrete answer with a name or example scores 2, a general promise scores 1, and silence scores 0. Shortlist only vendors that score at least 1 on IP, security and the exit row; a strong score elsewhere does not offset a weak one there. Before signing a scope, call one reference the vendor names, not one it curates, and ask what went wrong as often as what went right. A small paid pilot, such as one feature or a documented bug fix, shows real delivery, review speed and communication faster than another round of calls.

Worked example: 4over4

4over4 runs an online printing store and worked with Netbase on its e-commerce platform: conversion and checkout work, search, automated conversion of Adobe Illustrator (.ai) files to SVG, and a recommendation engine. As reported in the published case study, revenue grew 82% within six months, conversion rose 48%, average order value rose 35% and fulfilment time fell 50%.

The lesson for outsourcing buyers is the scope: a Vietnamese team working inside a live commerce business, on revenue-critical flows. The figures reflect the whole project, not any single feature. Read the 4over4 case, or see retail and e-commerce.

What delivery record exists, and what does not

Netbase JSC was founded in 2012, works from its only office, the head office in Hanoi, and has served 500+ clients. It is a consulting company first; outsourced teams are one delivery option, not its main offer. Its published record is strongest in commerce and web-to-print, including 50+ custom web-to-print platforms. It has no office or team outside Vietnam and does not offer Japanese, Korean, German or Chinese as a delivery language. Judge any vendor, including us, by the checklist above.

Common mistakes

• Buying the lowest day rate. A cheaper team that needs twice the supervision is not cheaper.
• No product owner on the client side. Offshore teams stall when decisions wait. If no one owns technology decisions, a fractional CTO can.
• Fixed price on an unsettled scope. Every discovery becomes a change request.
• Repositories and cloud accounts in the vendor's name. It turns a parting of ways into a rescue project.

Limitations of this guide

This is practical guidance from Netbase delivery experience, not market research, and it gives no salary, rate or market statistics. Legal points are general, not legal advice; have your own counsel review IP, data-transfer and liability terms. The 4over4 results were reported for the whole engagement and depend on that client's baseline.

How this guide was made

The Netbase Editorial Team wrote this guide from Netbase's published delivery, engagement and security pages, the 4over4 case study, and public sources on Vietnam's IP framework and EU data transfers. David (CEO) reviewed every Netbase fact. Drafting used AI assistance (Claude).
