Custom software, when
automation is not enough.
Sometimes the work does not fit any tool you can buy. Then we build a web app or internal tool around how your team actually works, at a fixed price, with AI features only where they are useful.
Fixed price and clear scope, agreed before work starts.
- ORDERSEvery order in one place, with its status: new, packed, sent.
- ROLESSales, warehouse and finance each see what they need.
- REMINDERSOrders that get stuck are flagged to their owner.
- AI, LATEROptional. Added only when it fixes a real problem.
When a custom app makes sense
We pick the smallest fix that works. A custom app is the right fix when one of these is true.
The process outgrew spreadsheets
Orders, stock or projects live in several files, and nobody is sure which one is current.
No tool fits how you work
You tried software off the shelf, and the team went back to chat and Excel because it never fit.
Several teams touch the same work
Sales, operations and finance each need their own view of the same records.
Automation alone is not enough
You need screens, roles and approvals, not only data moving in the background.
How a build runs
Nothing is built until you agree with the plan.
- STEP 1
Free diagnosis
We map the real process and check whether a simpler fix would do. If it would, we say so.
- STEP 2
Fixed-price proposal
The screens, roles and rules to build, a timeline and one fixed price. Work starts after a 50% deposit.
- STEP 3
Build and test
We build the app, show it to your team as it takes shape, and test it with your real work before handover.
- STEP 4
Handover, then an optional retainer
Docs and training for the people who use it. An optional monthly retainer covers monitoring and small changes.
Change requests are quoted separately, so the original price stays fixed.
What you get at handover
An app your team can run day to day.
A working web app
Built around your process, tested with your real work, and used in the browser.
Documentation
How the app works, who can do what, and where the data lives.
Team training
A session for the people who use it, in Bahasa Indonesia or English.
Free fixes for 30 days
Bugs found within 30 days of handover are fixed for free. New requests are quoted separately.
AI features only where useful
A custom app does not need AI to be useful. We add it when it fixes a real problem.
AI features
Screens, roles and approvals
No AI neededPlain software does this best.
Reading documents into the app
Uses AIAI pulls the details from invoices or CVs, and a person checks them.
Search and summaries
AI optionalCan be added later, once the app is in daily use.
Custom software questions
Something else on your mind? Ask it in the form below.
When do you build an app instead of automating?
When the work needs its own screens, roles or approvals, or when no tool you can buy fits how your team works. If an automation or a clean spreadsheet fixes the problem, we recommend that instead.
How long does a project take?
It depends on what we are fixing. A focused automation is usually quicker than a custom app. Your proposal includes a timeline, agreed before work starts. AI projects start with a pilot on one workflow, so you see results early.
How do we know it works before you hand it over?
We test it with your real work and your team before handover. For AI projects we start with a pilot on one workflow, so you see it working with your own data before you commit to more.
Do we need technical staff to use it?
No. We build it into the tools your team already uses and train them at handover. Someone on your side should own the process, but they don't need to be technical.
What do we get at handover?
Documentation of how the system works and where everything lives, plus training for the people who use it. The goal is that your team can run it day to day without us.
Can we add more later?
Yes. Many teams start with one problem and add more once the first fix works. Each new piece of work gets its own fixed-price proposal.
