E-commerce, booking systems and member areas
Once a site takes money, stores customer data or replaces a staff member, a mistake costs far more than the build.
Overview
A shop or booking system is software, not a brochure. It stores names, addresses, phone numbers, purchase history and sometimes card data. Every form is somewhere a stranger will try to type something they should not. We design these systems by first asking what could break, and only then what should look good.
Work in this tier is quoted per project, once we understand your process, the systems that must connect and the data volume. Pricing starts at ฿89,000 for a well-scoped system and most land between ฿89,000 and ฿250,000.

Who it is for
- Shops that want their own store instead of paying marketplace fees on every order
- Hotels, resorts, clinics and studios that need online booking tied to a calendar and payments
- Businesses that need a member area, online courses or a customer dashboard
- Organisations that must connect the site to existing accounting, ERP or CRM systems

- 04LINE Messaging API integration for order and booking notifications
- 05OWASP-aligned protection: input validation everywhere, rate limiting, audit logging, encryption of sensitive data

- 07A staging environment separate from production, and load testing before launch
- 08System documentation, source code handover and a system-level care plan
How it works
- 01
Scoping sessions
One or two sessions to write a scope precise enough for a fixed price. The fee is credited against the project if we proceed.
- 02
Quote and plan
Fixed price against the scope, paid in milestones. Typically 8–16 weeks.
- 03
Build in iterations
Delivered piece by piece on staging. You use it for real and give feedback every two weeks.
- 04
Security and load testing
OWASP checklist, payment flows in test mode, and load tests at the traffic you expect.
- 05
Launch and handover
Go live, train the team, hand over documentation and source, and start the care plan.
Not the right fit if
- You need to open this month: Shopee, Lazada or LINE Shopping are better in the short term
- The product or process is not settled yet: start with the business tier and add systems later
- You need it under ฿89,000: a system that takes money and stores customer data cannot be made safe on that budget, and we will gladly point you to an off-the-shelf option instead

Questions
+–Can we use Shopify or WooCommerce?
Sometimes. If your business fits a standard mould we will say plainly that an off-the-shelf platform is better value, and help configure it securely. This tier is for when your process does not fit, or when monthly and per-transaction fees have become more expensive than owning the system.
+–Which payment methods can you accept?
PromptPay QR, credit and debit cards via Omise or 2C2P, bank transfer with slip upload, instalments, TrueMoney and whatever provider your business already uses. Card data never touches your server.
+–Why the scope document?
Because complex systems fail on misunderstanding, not code. The scope makes a fixed price possible and tells you in advance exactly what you get. Anything added along the way is quoted separately and transparently.
