Buying a cheap domain name: how small businesses should choose

Buying a cheap domain name isn't hard, but a low first-year price isn't always the real cost. What matters more is picking the right domain extension, a trustworthy registrar, and understanding how the price changes from year two before you commit to a name for your website or company email.

What a domain name is and why businesses need one

A domain name is the text address that stands in for a server's numeric IP address, for example yourcompany.com. For a small business, a domain isn't only for a website — it's also the requirement for creating a company email address (like ten@tencongty.com) instead of relying on free Gmail or Outlook accounts. A domain registered correctly and renewed consistently becomes a long-term digital asset tied to the brand.

Choosing a domain extension: .com, .vn, or .com.vn

The TLD (top-level domain) doesn't affect how a website technically runs, but it does affect how customers perceive it and what registration requires.

.com and other international extensions

.com is the most widely used extension globally and doesn't require you to be a citizen or licensed business of any specific country. It's usually the simplest option procedurally if your company doesn't yet have a business license or wants to register quickly. Other open extensions like .net, .co, .biz, and .online work the same way and are often used when the preferred .com name is already taken.

.vn and .com.vn

.vn is Vietnam's national domain, managed by the Vietnam Internet Network Information Center (VNNIC), while .com.vn is a second-level domain under .vn. According to VNNIC, registration follows five steps: choose the domain name, choose a registrar, complete registrant verification, complete registration, then start using the domain. The registrant must be an individual with valid personal identification or an organization/business with legal status in Vietnam; the registrar will request information and copies of documents to verify identity before the domain is activated. Because of this verification step, .vn/.com.vn registration typically takes longer than .com, but several Vietnamese registrars note that a .vn domain tends to look more trustworthy to local users. Exact document requirements can change over time, so confirm the current list directly with your chosen registrar.

Why domain prices vary so much

Three factors explain why two .com domains can be priced very differently — check each registrar's published pricing to compare directly:

1. First-year promotional price versus renewal price. Many international registrars advertise a low price for the first registration year, then charge the standard renewal rate from year two onward — user communities have reported renewal prices several times higher than the first-year price. Check the registrar's published renewal price table, not just the new-registration price, before deciding.
2. Rare versus common extensions. Some newer or specialty extensions are priced higher than a standard .com/.vn from the start.
3. Bundled features. Hiding registrant information from public WHOIS lookups (WHOIS/domain privacy), transfer-lock protection, or advanced DNS may be charged separately or included for free depending on the registrar.

Choosing a registrar

The registrar is the company you pay and manage your domain through — either an international registrar (such as GoDaddy, Namecheap, Cloudflare Registrar) or a domestic registrar licensed by VNNIC (such as P.A Vietnam, Mắt Bão, Nhân Hòa, iNET, and others). A few things worth checking before choosing one:

• For .vn/.com.vn: only buy through a registrar on VNNIC's officially licensed list — VNNIC publishes its official registrar system on its own site.
• Whether the registrar supports domain transfer and issues an EPP/authorization code if you later want to move to another registrar, or whether it locks you in.
• Whether WHOIS privacy is enabled by default or charged separately.
• Whether auto-renewal is on by default — know this in advance to avoid losing the domain from a forgotten renewal, or being charged unexpectedly.

Steps to buy a domain name

1. Check whether your desired domain name is available using the WHOIS lookup tool on a registrar's site.
2. Compare both the first-year price and the renewal price across at least two or three registrars for the same extension.
3. Review the WHOIS privacy, transfer, and auto-renewal policies before paying.
4. Enter accurate registrant information (this is the official registration record, not something to casually change later).
5. Complete payment and wait for the confirmation email activating the domain.
6. If it's for a website: point the DNS records (A/CNAME) to your hosting provider.
7. If it's for company email: add the domain to the email service you use and verify ownership.

What to do with a domain once you have it

Once you own a domain, the most common next step for a small business is connecting it to an email and collaboration service. According to Microsoft's documentation, adding a custom domain to Microsoft 365 requires verifying ownership by adding a TXT (or MX) record to the domain's DNS at your registrar; Microsoft then configures the records needed for email to flow through that domain — this works with most registrars, and some support it automatically through a feature called Domain Connect. Microsoft 365 Business fits well if your company already relies on Word, Excel, and wants email addresses like ten@tencongty.com. If your team works mostly in the browser and is used to Gmail and Drive, a newly bought domain connects the same way to Google Workspace — verify the domain, then create mailboxes under your own domain name.

Note: a domain's mail should only route to one email system at a time (an MX record points to only one destination), so if you're weighing two services, decide first before touching DNS rather than switching back and forth.

Common mistakes to avoid when buying a cheap domain

• Don't pick a domain based only on the lowest first-year price without checking the renewal price — domain user communities have repeatedly reported renewal costs far above the advertised first-year rate.
• Don't leave auto-renewal on without periodically checking your payment card and notification emails — an expired domain can be registered by someone else.
• Don't register a .vn/.com.vn domain through an unclear intermediary outside VNNIC's list of recognized registrars.
• Don't register a domain under one individual's personal registrant details while a company depends on it long-term — if that person leaves, regaining control of the domain becomes complicated.

Frequently asked questions

Where is it safe to buy a cheap domain name?

It's safer to buy through a widely recognized registrar — for .vn/.com.vn, one on VNNIC's licensed list; for .com and other international extensions, a major registrar with clear customer support — rather than through an intermediary that doesn't disclose registrant information publicly.

Is buying a cheap .com domain different from a .vn domain?

Yes. A .com domain registers faster because it doesn't require domestic identity verification, while .vn/.com.vn is managed by VNNIC and requires verifying personal or business documents before activation, though it's often seen as more trustworthy to local Vietnamese users.

Does buying a domain for a website automatically give me a website?

No. The domain is only the address; you still need hosting or a website-building platform, then point the domain's DNS records to it before the website becomes visible.

Why is the domain renewal price higher than the first-year price?

Many registrars use a low first-year price to attract new customers, then apply the standard renewal rate from year two onward. Check the published renewal price table before registering, not just the initial advertised price.

Can a domain I already bought be transferred to another registrar?

Yes, most domains can be transferred to another registrar after a minimum period from the registration date, using an authorization (EPP) code from the current registrar. Ask about the registrar's transfer policy before buying if you might switch later.
