Short answer: pick a web development company whose portfolio sites are still live and load fast, whose quote sits inside the market range with a contract that spells out the scope, that puts the source code and domain in your business's name, and that splits payment 50/50 rather than asking for everything upfront - then compare at least three before you sign.
"Which web development company should I hire?" is the most common question Thai business owners ask before investing in a website. With hundreds of providers in Thailand - from freelancers charging a few thousand baht to full-service agencies charging six figures - choosing the right one can be overwhelming. Cheap doesn't mean good value, and expensive doesn't guarantee quality. Whether your budget is 5,000 or 500,000 THB, the principles are the same. This 10-point checklist works for comparing any provider, complete with real market pricing for 2026 (for a more detailed breakdown, see the 2026 website pricing guide).
1. Check Real Portfolio - Not Just Pretty Templates
The first thing to check is the agency's portfolio. Ask for links to live sites, not just screenshots, and don't just look at whether it's pretty. Verify these three things:
- 1.Are the portfolio sites still live? Many agencies showcase work from clients who've moved on. If they can't give you a single link to a live project, be cautious
- 2.Is it custom work or just a purchased template with a name swap? Check via BuiltWith.com or view the source code
- 3.Do the portfolio sites load fast? Run them through PageSpeed Insights. A score below 70 means the agency doesn't prioritize performance - and if their own work scores poorly, yours will too
2. Evaluate Their Technology Stack
The technology used to build your website directly impacts Performance, SEO, and long-term maintenance costs. In 2026, the three main technology groups are:
| Technology | Pros | Cons | Best For |
|---|---|---|---|
| WordPress | Cheap, many plugins | Slow, security-prone, frequent updates | Low budget, simple sites |
| Custom Framework (Next.js, React, Vue) | 3x faster, better SEO, more secure | Higher upfront cost | Serious businesses, budget > $900 |
| Website Builder (Wix, Squarespace) | Easiest to use | Very limited, poor SEO | Testing only, not for real businesses |
If your budget exceeds 30,000 THB (~$900), choose a Custom Framework over WordPress for better long-term value. Read more: Next.js vs WordPress - detailed comparison
3. Market Pricing for Web Development in Thailand 2026
Quotes vary widely because they depend on five main factors: number of pages, special features, technology, SEO structure, and post-launch support. A good company states its price clearly from the start and shows what each part costs. If a company says it will "evaluate later" without giving any price range, watch for hidden costs. Web development pricing in Thailand 2026 by type:
| Website Type | Price (THB) | Price (USD) | Timeline |
|---|---|---|---|
| Corporate Website | 25,000–80,000 | $700–$2,300 | 3–6 weeks |
| Restaurant/Cafe | 20,000–50,000 | $570–$1,400 | 2–4 weeks |
| E-commerce | 40,000–150,000 | $1,100–$4,300 | 4–8 weeks |
| Clinic/Healthcare | 35,000–100,000 | $1,000–$2,900 | 3–6 weeks |
| Real Estate | 50,000–200,000 | $1,400–$5,700 | 4–8 weeks |
| Landing Page | 8,000–25,000 | $230–$700 | 1–2 weeks |
If an agency quotes significantly below these ranges, be cautious - it's likely a template, not custom work
4. Ask About SEO From Day One
A beautiful website that nobody can find on Google is money wasted. Ask at the quotation stage whether basic SEO is included in the price or sold as a separate add-on - some agencies split it out - and get a list of exactly what is included. A good web agency must deliver:
- •On-page SEO basics - Title Tags, Meta Descriptions, Heading Structure, Image Alt Text, Sitemap.xml
- •Core Web Vitals compliance - LCP ≤ 2.5s, INP ≤ 200ms, CLS ≤ 0.1
- •Schema.org Structured Data - Organization, BreadcrumbList, FAQPage
- •Mobile-First design - Google uses the mobile version for ranking
Key question to ask: "Will the website pass Core Web Vitals?" If the agency doesn't know what that means, think twice. Read more: 10 ways to speed up your website and pass Core Web Vitals
5. Contracts and Ownership
This is critical but often overlooked:
- •Who owns the source code? Some agencies retain ownership - if you leave, you lose your site. Make sure the code is yours
- •Whose name is the domain under? It must be your business name, not the agency's
- •Where is hosting? Know where it's hosted, whether you can migrate, and what happens if the agency closes
- •What are monthly/annual maintenance costs? Some agencies offer cheap builds but charge high monthly fees. Get all costs upfront
- •Does the contract specify scope, number of revision rounds, and timeline? All three must be in writing, not agreed verbally
- •Is there step-by-step approval? Each milestone (e.g. design before coding starts) should need your approval before work moves on, so you can ask for changes right away instead of discovering problems at the end
6. Evaluate Their Process
Agencies with clear processes deliver on time and on spec. A standard process should include:
- 1.Discovery - requirements gathering, business analysis
- 2.Wireframe/Design - layout design for approval before coding
- 3.Development - actual website build
- 4.Review & Revision - client inspection and corrections
- 5.Launch & Handover - go-live, training, handover
If an agency promises delivery in 3 days without this process, be cautious - it's likely a template with your logo swapped in
Will You Talk to the Developer or an Account Manager?
Also ask who you will actually talk to during the project. If everything goes through a non-technical account manager, requirements can get lost in translation and you end up with a site that doesn't match what you asked for. Talking directly to the developer doing the work cuts miscommunication significantly.
7. After-Launch Support
A website isn't a one-time project. Questions to ask:
- •Is there a warranty period? Standard is 1–3 months of free bug fixes
- •How are minor content changes billed?
- •Is there an SLA? If the site goes down, how quickly will they respond?
- •Do they handle security patches? Especially critical for WordPress
- •Is there automatic backup? At minimum, weekly backups should be standard
8. Verify Reviews and Testimonials
Don't trust reviews on the agency's own website alone. Check these sources:
- •Google Reviews - search the agency name on Google Maps
- •Facebook Page - look at real comments and reviews
- •Ask for direct references - confident agencies will provide contact details of past clients
- •Ask in Facebook groups - Thai business groups like "SME Thailand" often have real experience sharing
9. Red Flags to Watch For
Avoid agencies that show these warning signs:
- •Have no portfolio, an outdated one, or only template-based work - indicates no real experience, or past work not good enough to show
- •Quote suspiciously low prices (e.g., an e-commerce site for 5,000 THB, or a "custom" site for under 2,000 THB, which is usually a purchased WordPress template with the name changed)
- •Force you to use their hosting with no migration option, or won't hand over the source code - vendor lock-in that means switching providers requires a full rebuild
- •Won't disclose their technology stack - may be using free builders and charging custom prices
- •Require 100% payment upfront - standard is 50/50
- •Have no written contract, or one that doesn't specify scope, revision rounds, and timeline - this creates risk in every scenario
- •Unreasonably long timelines - a standard corporate site takes 3–6 weeks and a landing page 1–2 weeks (see the table in point 3). If you're quoted 3–6 months for an ordinary site, ask why
10. Compare at Least 3 Agencies
Never choose from just one option. Request quotations from at least 3 agencies and compare:
- •Price vs. scope - don't compare price alone
- •Technology used - WordPress, Next.js, Wix produce very different results
- •Delivery timeline - too fast likely means templates, too slow may mean they're overloaded
- •Post-delivery terms - maintenance costs, warranty, SLA
- •Industry expertise - agencies with experience in your specific industry will understand your needs better
Freelancer or company? Freelancers suit low budgets and simple sites, but the common risks are no post-launch support and inconsistent quality. Size isn't the deciding factor - run every provider through this same checklist. Whoever gives clear answers on warranty, source code, and the contract is the lower-risk choice.
