Website production from one template
「Build once, sell repeatedly」
You do not rebuild per client. You build one template and change settings. From the second job on, the time you save is the margin.
Ship small-business websites from a single reusable template. In a 2026-08-20 count on the Korean marketplace Kmong, this category had the highest median review count of everything measured, at a list price well above the median.

- Building the first template takes days. Time to first order is not something we estimate — we have no sample.

We have zero cases with a verified earnings figure, so we do not invent a revenue range. What follows instead is arithmetic on published prices and official fee rates.
Where the money goes
One sale, start to finish — Market median · online store build
This is also the figure you report as revenue — not the amount that reaches your account.
- Service fee (16.4% / 9.4% / 4.4% 누진 구간)−₩90,200
- Payment network fee (3.3%)−₩18,150
- VAT on those fees (위 두 항목의 10%)−₩10,835
Output VAT ₩50,000 − input VAT on fees ₩10,835−₩39,165
⚠️ Tool costs, your own labour and income tax have not been taken out yet. Individual (non-business) accounts handle VAT differently and cannot issue tax invoices at all.
The ceiling you cannot pass in a month
Published delivery days divided into the working month. Not what you can earn — the line you cannot cross alone.
What these numbers are, and are not
- Nobody earned this. Not one listed case has a verified revenue figure.
- List prices and delivery days come off the seller's page; fee rates come from the platform's own documentation.
- “Max/mo” is division — 20 working days divided by the published delivery time. It does not mean orders arrive that steadily. In practice they do not.
- Operating profit here is before tool costs, your own labour and income tax. Rework and refunds are not in it either.
Who you sell to
- Neighbourhood shops
- Workshops and makers
- Places taking bookings by phone
How the money comes in
- Per-project fee
- Three-tier packages
Steps
- Narrow to one trade — the tighter the trade, the more the template is reused
- Build once so that changing a single config file produces the next site
- Add a screen the owner edits themselves. If changing a phone number needs you, it is unfinished
- Lock the admin screen. Leave the customer enquiry form open
- Put a demo on a real address — buyers look at screens, not mockups
Tools used
Risks
- The first template is sunk time. If nothing sells, that time is not recovered
- Without a written maintenance scope, «just one more line» never ends
- Any «no monthly fee» claim must state that the domain is billed separately
- Clinics fall under medical advertising rules. List prices are higher there, but the same count found almost no transactions
