The short answer

What kind of website or app does a lending, insurance or investment business need so customers trust it and finish applying?

A good finance website explains products in plain language, lets people try calculators for repayments, premiums or returns, uses a short step-by-step application form that works on a phone, and shows security, licences and PDPA information clearly. Before launch, check your advertising content against the rules of the regulator that supervises your business.

How customers search and decide on financial products in 2026

Thais are very comfortable with digital money. The Bank of Thailand reports around 651 digital payment transactions per person in 2024. Customers therefore expect applying for a loan or buying insurance to be as easy as a mobile transfer. If your site still asks people to print forms or visit a branch, they will move to a provider that makes it easier.

Money is also where people are most careful. Before deciding, customers compare several providers, read reviews, check whether the company is actually licensed, and ask AI assistants to explain terms they don’t understand. News about online scams has made people wary of links and sites that look unfamiliar. Trust has to come before looks.

Must-have pages and features

Each product needs its own page that answers four questions: who it is for, what they get, what it costs or risks, and how to apply. Write it in words anyone can follow, and keep the full terms one click away. Calculators let customers see their own numbers before deciding, and they are often where people spend the most time on a finance site.

The application form is where most people drop off. Split long forms into short steps with a progress bar, save answers so people can come back later, and ask only what is needed at each step. If documents are required, let people take a photo with their phone right there.

  • Product pages in plain language
  • Repayment, premium or return calculators
  • Step-by-step forms that save progress
  • Licences, company details and complaint channels
  • Security and scam-awareness page
  • Privacy policy and cookie controls

Integrations common in Thailand

Finance sites in Thailand usually connect to several back-office systems: a CRM that sales staff or agents use to follow up, a loan decision or underwriting system, and online identity verification (e-KYC) for some products. PromptPay QR and card payments let customers pay premiums or instalments on the spot.

LINE OA works well for application status updates, payment reminders or booking a call with staff, but be careful with links. Thai banks stopped sending links by SMS and email following Bank of Thailand anti-scam measures, so customers are used to opening the app or typing the address themselves. Design your messages with that habit in mind.

Content, SEO and AEO for finance

People search for money topics as questions, such as “what documents do I need to refinance a home?” or “how much health insurance can I deduct from tax?”. Content that answers these directly and completely, and is updated each year, brings in people who aren’t ready to apply yet, and it is the kind of source AI assistants like to quote.

Google treats financial content as something that affects people’s lives, so it weighs trust heavily. Show the name and expertise of the writer or reviewer, date each update, cite official sources, and avoid promises such as “guaranteed approval” or “high returns with no risk”.

Regulation, security and PDPA

Financial products in Thailand are supervised by different bodies: the Bank of Thailand for banks and many kinds of lending, the SEC Thailand for investments and digital assets, and the Office of Insurance Commission (OIC) for insurance. Each has rules on advertising and disclosure, such as how interest rates, fees and risk warnings must be shown.

These rules change, and the details depend on your licence type, so this guide gives an overview only and is not legal advice. Before launching a site or campaign, check the latest notifications with the relevant regulator and your compliance team.

For security, use HTTPS on every page, encrypt sensitive data, limit back-office access and test for vulnerabilities before going live. Under the PDPA, financial details and identity documents need careful handling: state the purpose clearly and ask for separate consent before using data for marketing.

How to measure results

The key measures are form completion rate and the number of applications that qualify, not just how many people start. Track which step people abandon, then fix that step. This usually helps more than redesigning everything.

Watch calculator use as well: people who use a calculator and then move on to the form show strong intent. If you run ads, feed CRM data back so you can see which channels bring approved customers, not just a high number of applications.

  • Form completion rate and drop-off step
  • Qualified or approved applications
  • Calculator use that leads to the form
  • Cost per approved customer by channel

Common mistakes

The most common mistakes are one long page that asks for everything up front, jargon customers don’t understand, and fees tucked away in attachments. Besides hurting trust, hidden fees may also conflict with disclosure rules.

Another is a site that looks different from the company’s app or documents, which makes customers wonder if it is fake. Use a domain you own, the same logo and colours everywhere, and tell people clearly how to recognise your official channels.

A realistic launch roadmap

Finance projects carry more review steps than most industries. Allow time for legal and compliance to review content, and for security testing before launch. A product site with calculators and an application form often takes around 10–16 weeks; a mobile app or several back-office integrations can take longer.

Launch one product at a time, starting with the one customers ask about most. See where people drop off, fix it, then roll out to other products. This lowers risk and lets the team learn as it goes.

  • Weeks 1–3: requirements, rules and application flow
  • Weeks 3–6: plain-language copy, design and prototype testing
  • Weeks 6–12: build, CRM, payments and LINE
  • Weeks 12–16: compliance review, security testing and launch

Frequently asked questions

Why don’t applicants finish our form?

Common causes are a single long page, questions that aren’t needed yet, poor mobile usability, or no sign of how many steps are left. Splitting the form into short steps with a progress bar, saving answers for later and letting people photograph documents on their phone usually helps more people finish.

What does a calculator on the site actually do for us?

A calculator lets customers see their own numbers, such as an estimated monthly repayment or premium, before they get in touch, so the people who reach your form already understand the product. Make clear the figures are estimates and show the assumptions used, in line with the rules that apply to you.

Which authority do we check our advertising with?

It depends on your business. Broadly, banks and many lenders fall under the Bank of Thailand, investments and digital assets under the SEC Thailand, and insurance under the Office of Insurance Commission. Rules change, so check the latest notifications directly with the authority and consult your compliance team or a legal adviser.

Should we build a website or a mobile app first?

If the goal is finding new customers, the website usually comes first, because people reach it from Google and ads without installing anything. Apps suit existing customers who use them regularly, for example to check balances, pay instalments or follow investments. Many businesses start with the website and add an app once they have regular users.

How secure does a finance website need to be?

At minimum: HTTPS on every page, encryption of sensitive data in transit and at rest, limited back-office access, two-factor login for staff and vulnerability testing before launch. Licensed businesses may have extra standards set by their regulator, so check with your IT and compliance teams.

Can we send customers links by SMS?

Be careful. Thai banks stopped sending links by SMS and email following Bank of Thailand anti-scam measures aimed at reducing scams, so many customers distrust links in messages. It is better to ask customers to open your app or type your address, or use a verified LINE OA, and to check the rules that apply to your business.

Does educational finance content really help sales?

Over time, yes. Most people research several times before a money decision. Articles that answer real questions honestly get your brand found early and build trust before anyone applies. Include the writer or reviewer’s name, date each update, and avoid promises about returns or approval.

How does the PDPA apply to finance customer data?

Income details, identity documents and financial history need strict handling. State the purpose clearly, collect only what you need, ask for separate consent for marketing, and give customers a way to view or delete their data. Your regulator may add specific requirements, so consult a legal adviser.
