“Our products are in a PDF. Buyers abroad can't find us.”
A catalogue search engines find, with an enquiry form on every product; each enquiry reaches your team's chat within a minute.
The software your business has been putting off, built in weeks.
Tell us what you need. Within three working days there is a written agreement in your portal, with the days and the price. Nothing is due until you accept, and the price is fixed once you do.
- Fixed price per milestone
- Stop after any milestone

01 · What we build
The ask in your words. The thing that ships.
Six of the things owners bring us. Illustrations of the kind of work, and every one of them comes with operations from launch.
Ordering
“Wholesale orders come in on WhatsApp and get lost.”
Customers order from their own price list; your team works from one list per delivery day.
Partners
“Distributors keep asking for the same price lists and files.”
A partner area with sign-in, price lists and documents, kept current by you.
Connections
“Enquiries live in three inboxes and a spreadsheet.”
One pipeline: every enquiry with its source, an owner and a status, and the team told in the chat they already use.
AI
“My team spends days turning a brief into a shortlist.”
The brief goes in, a checked shortlist comes out; your team edits it and sends it.
Report
“I never know whether the site is even working.”
A monthly report you read in two minutes: enquiries by source, uptime, speed, and what changed.
02 · How it works
Four steps, the same for every project
So you know what happens next and what it costs before it happens.
- 01
Tell us what you need.
In your own words, with a budget in mind if you have one. You hear back within one business day. If we have questions, we ask them by email; then you receive an invitation to your portal, where everything that follows lives.
You payNothing - 02
Read the agreement.
Within three working days of your enquiry, the first version is in your portal. Scope is written as features and use cases, one checkable sentence each. Each milestone lists its work items with their days, and the first milestone carries a firm price. Comment on any line; we answer in the next version. Nothing is paid and nothing is signed.
You payNothing - 03
Accept, pay, and it gets built.
Accepting locks the first milestone at its price. You pay it in the portal and the build starts. You follow its status there, we review it together, and it launches.
You payThe milestone, upfrontFixed once accepted - 04
It runs, and the next milestone gets its own round.
From launch, operations is $49 per month: monitoring, updates, backups, small changes, and a monthly report. Infrastructure is passed through at cost, itemized. Later milestones are priced at their own round, when you are ready. Stop after any of them.

03 · The agreement
This is what you read before you pay. The price is arithmetic.
The first milestone of a sample agreement, as the portal shows it. Every line takes a comment; every day is on the table.

Every milestone lists its work items with their days, so the price is arithmetic you can check. Once you accept a milestone, its price is fixed; if it takes us longer, that is ours.

Sized to your budget
The first milestone is sized to the budget you name. What does not fit waits for a later one.
Scope fixed as written
A change becomes a new feature or milestone with its own days, so nothing appears on an invoice you did not accept.
One milestone at a time
One milestone is paid at a time. Later milestones carry no price until their own round.
Stop after any milestone
What you paid for is yours.

What we hold, and what is yours whatever happens
End operations any time. Nothing is handed back because nothing is held; we walk whoever takes over through the operating documentation.

06 · Questions
The things worth asking
How do I know the price is reasonable?
Every milestone shows its work items with their days at $799 a day, and the scope is written as use cases you can check one by one. Put the same use cases in front of anyone else and compare. If the number does not fit your budget, say so: the first milestone is sized to what you name, and the rest waits.
What if you underestimate?
Once you accept a milestone, its price is fixed. If it takes us longer, we carry that. It is also why the first milestone is scoped carefully and written in checkable sentences.
What if I change my mind during the build?
Scope is fixed as written, so the price cannot drift. A change goes into the agreement as a new feature or milestone with its own days and price, and you decide whether it is worth it.
Can I stop after the first milestone?
Yes. Later milestones carry no price and no commitment until their own round. What you paid for is yours, and operations continues only as long as you want it.
Is the work done by AI or by a person?
A senior engineer is accountable for everything that ships and reviews all of it. The code is written with AI agents under that review, which is what makes a day buy what it buys. The largest companies already build this way; the same leverage should be available to a business of any size.
What kinds of projects?
Websites with catalogues and enquiries, customer and partner portals, internal tools, connections between the systems you already use, and the running of all of it afterwards. If it is a good fit, the agreement shows how. If it is not, we say so in the first reply.
What happens after launch?
Operations, $49 per month: monitoring, updates, backups, support and small changes, and a monthly report of what happened. New features are new milestones, priced at their own round.
I already have a website and some tools. Do they get replaced?
Only where they should be. The agreement says what is kept, what is replaced and what is connected, and why. Accounts held by a previous vendor are moved into your name as part of the work where that is needed.
How much of my time does it take?
The enquiry, reading the agreement, answering our questions, and a review at the end of each milestone. Everything else happens in writing in the portal, at your pace.
Where are you, and in what language?
Hong Kong. English and Chinese. The work runs in writing in the portal, with a call when it helps.
Why the name?
The keel is the part of a boat you never see: the weight below the waterline that keeps it upright and holds its course. That is the job we take for your software.
