See it, touch it, and keep changing it. There is no extra fee for that trial and error. We deliver a working system in as little as two weeks. Touch the live screens and request changes freely. That is how to build a system without failure.
- It is difficult to imagine the final product from paper documents alone. That is why we first show you a working prototype within two weeks.
- Try it yourself and tell us frankly, "This is hard to use" or "We want it this way." Unlike typical development, we never charge extra for specification changes.
- Without worrying about budget overruns, we keep refining within a flat monthly fee until you are satisfied. You do not need perfection from day one; this is the most practical and reliable style of development.
* No hard selling. Ever.
AI writes, humans lead.
AI and modern technology have changed what is considered normal in development. Half the cost, double the speed. That is our engineering.
The Old Way What used to be normal
Every revision added extra cost
Under man-month pricing, rework directly increased costs. Teams had to give up improvements to protect the budget.
No visibility until completion
In waterfall, everything is fixed upfront. After waiting months, teams often ended up with something different from what they imagined.
Double cost for web and app
Because each was built by different languages and teams, both development cost and management overhead were effectively doubled.
New Standard How we build
Dramatic acceleration with AI
We let AI handle routine code generation, while engineers focus on usability. That is how we deliver high quality in a short time.
Decide specs while running
We first build a prototype in two weeks. By fixing specs after touching real screens, unnecessary revision costs do not occur.
One codebase for mobile and desktop
With modern technology, we generate web and apps at the same time. It drastically reduces not only development cost but also future maintenance cost.
Three benefits of a flat-rate plan
From one-off builds to a growing asset
You own all rights, so you can invest with confidence.
In conventional development, a system starts aging the moment it ships. Our approach is different. We add features as your business grows so the asset keeps gaining value.
All source code rights belong to you. Even after cancellation, the system you grew stays in your hands.
Fast beats perfect
Your business moves in two weeks.
You do not need to wait for a perfect blueprint. Start small with core features and grow the system while generating revenue.
From vendor to team
Your dedicated engineering department.
We are more than a vendor. We share your daily challenges and keep improving the system like your in-house team.
Every touchpoint, within a flat rate.
From headquarters web admin systems to on-site smartphone apps, one team builds everything your business needs end to end.

Not theory. Proven delivery.
From complex operations systems to consumer apps, Finite Field builds systems that drive business results.
Global order management system
A robust backbone for cross-border commerce. Centralize everything from English UI to document output and chat.
International transactions were managed via email and spreadsheets, creating complexity. Language barriers, time differences, and the workload of creating quotes, invoices, and packing lists became major bottlenecks.
We built a member-based ordering system. From catalog browsing to quote requests, orders, and PDF document output, everything is handled on the web. Every screen supports English to deliver a stress-free UI for overseas buyers.
Home-visit nursing matching system
See availability instantly. Real-time sales support that stops missed requests.
When external care managers were visiting clients and needed nursing support, they had to call to check availability. Delays meant opportunities were lost to competitors.
We visualized nurse schedules in real time. External care managers received accounts so they could search and confirm available nurses on their phones, enabling matches before placing a call.
Self-serve harvest and unmanned sales app
Pick it yourself, pay on the spot. Harvest experience plus Stripe payments for a fully unmanned farm stand.
Producers wanted direct sales without staffing costs. Consumers did not know what was available until they arrived, leading to frustration and fewer visits.
We built a new model in Flutter (Flutter Web) where consumers harvest and pay on their own phones. They can check available produce before arriving, scan a QR code on-site, harvest, and pay via Stripe immediately.
No heavy specs required.
Just drop requests in chat. You can freely reshuffle priorities anytime.
1. Ticket
Turn requests into tickets
2. Develop
Build in priority order
3. Review
Review and feedback immediately
Simple pricing that eliminates management risk.
Light
Maintenance phase / small internal tool updates
Standard

Business
Large-scale, rapid delivery / multiple lines
Logical tech choices that power rapid improvement.
Flutter (Web / iOS / Android)
Ship web and apps from one codebase. The source of exceptional productivity.
htmx
We use ultra-lightweight htmx for public pages such as landing pages and blogs.
Go / Rust
An ultra-fast backend built for high traffic. We use Go and Rust where each performs best. Even as your user base grows, the system stays responsive.
Cloud SQL / Firestore
We choose the best fit. Cloud SQL for complex structures, Firestore for real-time needs.
