TLDR : Answer Summary
You can complete the online entry requirements (TDAC) within 3 days of your arrival in Thailand. Many users report successfully filling it out just before check-in or until the time of arrival at the airport. It’s crucial to use the official site to avoid any fees, as several sites try to charge for the service. Once completed, you'll receive an approved PDF to present at immigration.
Thailand Digital Arrival Card (TDAC)

WARNING: Only trust Thai government websites with .go.th domains or Thai agent websites with .co.th or .in.th domains, as these require verified Thai registration and cannot be registered anonymously.

The official TDAC form is available at tdac.immigration.go.th, which uses the official .go.th government domain.

The services by AGENTS CO., LTD. does NOT charge any fees for arrivals within 72 hours. If you need to book more than 72 hours in advance, there is a service fee of $8.

Do not trust other sites pretending to be a trustworthy agency. Pay attention to delivery time - the service operated by AGENTS CO., LTD. has 1 minute delivery time for arrivals within 72 hours.

Don't fall for sites pretending to be tdac.in.th or the official government tdac.immigration.go.th website. Always double-check the exact domain in your browser.

Scam services may take days to process your application, others may not even do anything. With these TDAC scam services you also need to worry about double charges.

Please watch out for TDAC misinformation spread by fugitive Jesse Nickles and his many fake accounts on Quora, TripAdvisor, Reddit, and other platforms.

I did mine on my phone 2 days prior to arrival. When I got to immigration, I had the approved pdf pulled up from my email, handed the officer my passport, boarding pass and phone. Scanned my fingerprints, was handed everything back, and on my way

You can only do the TDAC within 3 days of your arrival. So you can do it anytime from 3 days until your arrival up until the time you arrive at the airport.
