Payment and handover

This page covers everything: how you pay, when you pay, and what form the work comes in. You always see every number once, summed up before work starts, including outside service fees that do not come to me.

Ways to pay

Clients in Thailand pay online

Pay online through Stripe. Choose PromptPay or a Visa or Mastercard card right in the payment box. The system confirms the payment by itself, so work can start right away without sending a transfer slip
Stripe takes the card details, so your card number never passes through this website's server
I issue a receipt for your accounts team as normal
Company clients can withhold 3% tax as normal. Please send me the withholding tax certificate (50 Tawi) as well. My tax ID is my 13-digit national ID number, given to you when the receipt is issued
No extra fees from my side

Clients outside Thailand credit card

Pay by Visa or Mastercard right on the payment page, charged in US dollars
Stripe takes the card details, so your card number never passes through this website's server
You can use Stripe's Link if you already have it, and pay in a few clicks
A receipt is issued automatically the moment the payment arrives, and sent by email

Before you pay, check me out first

I encourage it, not just allow it. Search my name, Phisit Tantiranon, on Google. It matches the name given everywhere on this website.

If you find anything that makes you uneasy, tell me straight. I would rather you check before you pay than sit and worry about it later.

When you pay, and in how many payments

One rule: you never pay ahead for work that does not exist yet. Every payment after the first is made after you have seen and checked the real work.

Websites, and work agreed on a quote under $2,249

Email me, get a quoteOne priceEvery item in scope and the total are on the quote, with nothing added later

Before work starts50% depositPaid through the payment link I send, then I start right away. You get a receipt for the amount paid

At handoverThe other 50%You check the site on my server first, and I fix anything that does not match what we agreed. After the final payment I put the site live on your domain

Work of $2,249 and up is split by phase. The number of payments and every amount are on the quote before work starts. No payment is added along the way, and you can stop after any phase.

Packages bought and paid online on this site straight away, without a quote, follow the payment and care terms shown before you pay.

How the work is handed over

My work is software, so nothing is sent by post. Handover is all electronic and happens within the time frame written in your scope document.

You check it on my server first
You can click through every page of the real site or system. Anything that does not match what we agreed, I fix free until it does, and only then collect the final payment. All the terms are on the acceptance and refunds page.
Source code goes into your own account
On work paid in full up front, the code goes into a GitHub account in your name from the first day of work, not at the end. So you hold the work the whole time and can change who looks after it whenever you want. On work split into two payments, including websites on a 50% deposit, you can look at and try the real thing on my server the whole time, and the code moves into your account once the final payment is complete.
The site or system goes live
Installed on your hosting or your domain, set up ready to use, and tested with you before it opens for real use.
User guide and files by email
A user guide in English with pictures, sent as a PDF within 1 business day of handover.
After you accept it, the work is all yours
The Business and Enterprise website packages, and any job over $749, include 1 year of free care. After that you can look after it yourself, or have me look after it for $809 a year. Your choice, not required.

Cancelling, refunds, and when something is wrong

One rule: work already done is not refunded, and work not yet done is not charged. There is no case where you pay and get nothing back. This is written into every contract before work starts and does not change along the way.

You cancel before I start full refund

Cancel any time before I begin. No reason needed, an email is enough
Full refund within 7 business days. No cancellation fee and no notice period

You cancel after I have started no refund on work already done

Time already spent cannot be sold again, but the remaining payments are not charged
All the work done so far and its source code are yours, and another developer can carry on with it straight away
On phased work you can stop after any phase, and you do not pay for phases not started
If I am the one who cannot continue, I refund the payments for work not done, with no handling fee, and hand over the work and documents so someone else can carry on
Cancelling covers work not yet handed over. Once everything is delivered and you have accepted it, the final payment is for work you already have. If the work does not match what we agreed, tell me first and I fix it until it does before I collect

If something is wrong with the work, talk to me before your bank. Email phisit@zyntronlabs.com and I answer within 1 business day. Disputing a card payment or asking your bank to pull the money back takes weeks, and it ends with nobody getting a working system back. The full terms are on the acceptance and refunds page.

Third-party costs

I list them clearly in the scope document, so none of them pop up later

A yearly domain fee, about $12–18 a year, always registered in your name and not mine (the Business website package includes hosting and the domain for the first year)
Hosting or servers, depending on the size of the system. Many small projects can really use a free service, and I will tell you straight
Monthly AI service fees, for work that uses AI, about $9–60 a month depending on real usage
Automatic transfer-slip checking, for systems that take payments, about $6–24 a month
A Google Play developer account, a one-time fee of about $25, for mobile app work

Security testing has just one rule

I only test systems you can show me written permission for, and the permitted scope goes into the contract before I touch anything. No exceptions, even when the site is clearly your own.

Why so strict? A penetration test and a break-in are exactly the same actions. The only thing that separates them is the written permission, not what the person doing it intends. So this rule protects you as much as it protects me. If the site sits on another company's hosting or another team looks after it, tell me and I will help draft the permission letter.
