How long does delivery take?

Landing pages: 5–7 days. E-commerce: 10–14 days. Multilingual corporate: 14–21 days. The exact milestone is locked before we start — if we miss it on our end, you get 20% off the contract.

What does flat pricing include? Any add-ons?

Pricing includes first-year hosting, first-year domain, SSL, design, build, sample copy, on-page SEO, AEO optimisation, and 1 month of post-launch support. No hidden fees — contract price = final price.

I don't have content or photos yet — can you still help?

Yes. We write copy in your industry's voice, use licensed stock or high-quality AI imagery, and connect you with a photo crew in HCMC or Hanoi if you need real shoots.

Can I edit the site after launch?

Yes — you get full admin access to edit text, images, products, and blog through the CMS. Structural changes (new features) go through our maintenance plan or are quoted per project.

What does ChatGPT / Gemini optimisation mean?

AEO — Answer Engine Optimization. We implement schema, FAQ blocks and structured data so AI search engines can quote your site when users ask LLMs. This is a customer channel 95% of Vietnamese sites miss.

How does payment work?

Pay in cash or by bank transfer to our company account.

I'm not tech-savvy — can I still manage the site?

Absolutely. The admin panel is minimal and clean. After handover we run a 1-on-1 60-minute walkthrough + screen-recorded videos for replay. We've onboarded 60-year-old clients who manage their site solo.

Will the Kaikun site rank well on Google?

Kaikun sites are built to 2026 SEO standards: Core Web Vitals pass, full structured data, mobile-first, sub-2-second load. That's 80% of SEO done. The remaining 20% — content and backlinks — is covered if you take our SEO add-on.

What if Kaikun shuts down after launch?

You own 100% of the source code + admin credentials. Your site runs independently on its own hosting — you can move it to any other provider. You're never locked into Kaikun.

Do you work in Japan? Is your Japanese accurate?

Yes. The founder has lived in Kansai, Japan since 2020 — fluent Japanese. Every Viet–Jpn site Kaikun ships is translated + reviewed by the founder directly, not Google Translate.

How we work

Four clear steps — you always know where you stand.

No "two weeks of silence then a surprise delivery." Each step has deliverables, sign-off, and revision rights. You see progress from day one to delivery day.

01
Day 1–2
Discovery & brief lock
A 45-minute Zalo/Meet call with the founder. We talk product, target customer, competitors, business goal. After the call you receive: a written brief, proposed sitemap, fixed price, committed deadline. You sign off the brief — work begins.
02
Day 3–7
UI/UX design
Unlike most studios that mock everything in Figma first, Kaikun builds a working UI demo directly on the live website. You preview it in your browser with the real fonts, colours, animations, and responsive behaviour. Approve as-is, or we refine the demo in place until it lands. No "the mockup looked great but the build feels different" gap.
03
Day 7–12
Build & optimise
Coded in Next.js — the same framework Netflix, TikTok, and Hulu use. Sub-2-second load times. SEO baked into the code. Responsive across every device. Search Console, Zalo OA, and Messenger wired in. Demos shared daily.
04
Day 13–14
Handover & warranty
A 60-minute handover call: admin tour, how to update posts/products, how to read analytics. You get the source code, admin credentials, and walkthrough videos. Lifetime technical warranty as long as you stay on Kaikun hosting.

Total timeline: 5–14 days depending on complexity. Exact milestones are written into the contract before you pay deposit.

Technical standards

Every Kaikun site ships with these 12 standards — not as "options."

No "this is an upgrade" or "pay extra for that." The 12 standards below are default on every package — even the cheapest 5万円 tier. This is how Kaikun defines "transparent flat pricing."

01
Sub-2-second load times
Next.js code + auto image optimisation + CDN. You never lose customers because the site is slow.
02
Mobile-first responsive
75% of web traffic is mobile. Kaikun designs for mobile first, then desktop — not a "shrunken" desktop version.
03
On-page SEO standard
Meta tags, heading hierarchy, alt text, sitemap.xml, robots.txt, canonical URLs — complete at handover.
04
AEO ready for AI Search
Schema structured data, FAQ markup, organization schema so ChatGPT, Gemini, and Google AI Overview can quote your site.
05
Free lifetime SSL
HTTPS certificate free + auto-renewal. Google prioritises HTTPS sites in rankings.
06
Easy-to-use CMS
You edit text, images, products, blog posts via a dashboard in your language. No code needed.
07
Zalo OA + Messenger integration
Floating chat button for 1-tap inquiries. Leads land directly in your Zalo/Facebook.
08
Smart lead form
Contact form saves leads to Google Sheet + emails you + pings your Zalo the moment someone submits.
09
Search Console integration
Track keywords & search performance — see which pages are indexed, which terms drive traffic, decide by real Google data.
10
Multilingual (optional)
Viet–Eng, Viet–Jpn, or 3 languages. Especially fit for real estate, study abroad, and export businesses.
11
Automatic backups
Weekly backups. Incident? Restore in 30 minutes. You never lose data.
12
You own the source code
100% source code delivered. Want to move to a different provider later — you have full rights.

An honest comparison

You have four options — Kaikun lays them side by side so you can choose.

We won't say "Kaikun is best." Each option fits a different need. The table below maps the trade-offs so you can decide with eyes open.

Criteria	DIY Wix / WordPress	Cheap studio < 4万円	Kaikun Tech	Big agency
Entry cost	Free – 2万円/year	2万円 – 4万円	5万円 – 10万円 flat	100万円 – 700万円+
Delivery time	2–8 weeks (self-learn)	2–4 weeks, often late	5–14 days, committed	2–6 months
SEO standard	Configure yourself	Usually none	100% default	Separate package
AI Search optimisation	Not supported	Don't know it	Default	Depends on team
Page load speed	Depends on template	Usually > 5s	< 2s, guaranteed	< 3s
Who actually builds it	You	Junior freelancer you don't know	The founder, in-house	Account → PM → Junior
Post-launch warranty	Your problem	Hard to reach again	Lifetime	By SLA contract
Source code handover	N/A	Rarely	100%	Separate package
Best fit for	Tech-loving spare-timers	"Just exists" sites	SMBs that want sales	Enterprises, banks

If you run a shop, an SMB, or a personal business — Kaikun is the sweet spot of price, speed, quality, and post-launch support. If you need enterprise-grade compliance, go with a big agency.
