Custom applications and specialised software, built to order
OOS Software works with businesses in Vietnam. We start from your business process, then build software that fits how you operate.
When does a business need its own software?
Off-the-shelf products suit work that everyone does the same way. When the way you work is what sets you apart, the software should be shaped around it. If a few of these sound familiar, it may be time.
- Data is spread across many Excel files, each department keeps its own copy, and the numbers do not match.
- Orders and approvals travel through chat and phone calls, so it is hard to trace who approved what, and when.
- Your current software forces you to change your process to fit it, instead of the other way round.
- Systems do not talk to each other, so staff re-enter the same data several times.
- Month-end reports take days to compile, and managers see the numbers too late.
- Field staff have no tool to record their work on the spot.
Our services
From a small tool for one team to a shared system for the whole company, we build software around your actual problem.
Internal business applications
Replace spreadsheets and paperwork with one shared system for orders, inventory, contracts, staff or finance. Data is entered once and used by every team.
Learn more →Specialised business software
Custom pricing or payroll rules, custom approval flows, or integration with the systems you already use: the things off-the-shelf products cannot do.
Learn more →Mobile and web applications
Apps for your field staff or your customers: ordering, lookups, photos and sign-off, right on the phone.
Learn more →Software maintenance and enhancement
We take over software already in use, even when the original developer no longer supports it. Fixes, performance work and new features, without starting from scratch.
Learn more →Hardware
Good software needs the right equipment. We supply and maintain hardware, so you have one point of contact for the whole system.
Equipment supply
Advice on and supply of computers, servers, network equipment, printers, barcode scanners and point-of-sale devices, chosen for how you will use them and the software they will run.
Learn more →Equipment maintenance
Installation, scheduled maintenance, repair and upgrades, so your systems run reliably with fewer interruptions.

We understand the business first
Specialised software only works when it matches the real process. We start from your problem, not from technology.
Object-oriented thinking
Systems modelled around objects and their relationships are easier to extend and maintain as the business changes.
Clear handover
Scope, schedule and results are agreed in writing, so you always know where the project stands.
Small steps, early results
Projects are split into short rounds. After each round you get a working version to try and comment on, instead of waiting until the end.
We speak your business language
We talk in terms of your orders, receipts and approval steps, not technical jargon. People who are not technical can still follow the project.
Support after handover
Your business will keep changing. We continue to fix issues and add improvements so the software keeps up.
How we work
Five steps, each ending with something concrete for you to review and approve before we move on.

Solution design
Data model, key screens and workflows, approved before any code is written.

Build in rounds
Small pieces at a time, each round with a working version for you to use and review.
