Company domain email pricing: per user or per organization

Two services can both give you email on your domain and still differ more than tenfold on the monthly bill. The difference is how they charge, not the mailbox.

Quick summary

Check whether the service charges per user or per organization.
Add the software you would have to buy separately: customer management, shared documents, file storage.
Multiply by your current headcount and the people you will hire in the next year.

Two ways to charge

Per user: every account is one seat fee. Google Workspace, Microsoft 365 and most customer-management software charge this way. One more hire adds one more seat to every monthly bill.

Per organization: one fee for the whole company buys shared storage and a mailbox allowance. Vietnamese email providers such as BizFly, and VNe, charge this way. Adding people within the allowance does not change the bill.

Providers change prices often. The figures above are public list prices on 28/10/2026, before private promotions or reseller discounts. Before deciding, open each provider's own price page from the Sources section below.

Example: a 10-person company that needs email and customer management

Assume all 10 people need email and all 10 use customer-management software. Google's price is converted at a reference rate of ₫26,000 per USD, using the regular price rather than the first-year promotion.

Google Workspace plus MISA AMIS CRM: ₫1,820,000 for email plus ₫550,000 for customer management, about ₫2,370,000 per month in total, roughly 11.9 times VNe Starter.
BizFly plus MISA AMIS CRM: ₫190,000 for email plus ₫550,000 for customer management, about ₫740,000 per month before VAT, roughly 3.7 times. No shared document editing.
VNe Starter: ₫199,000 per month for the whole company, including email, customer management, Drive and Office.

The biggest gap does not come from the mailbox price but from having to buy and connect a second, per-seat product.

When per-organization pricing is not cheaper

A two- or three-person company that needs nothing but email: the smallest plan of a local email provider may cost less.
Few people storing a lot of data: shared storage runs out before the mailbox allowance does.
A company deeply tied to advanced Google Docs or Excel features and industry add-ins: switching costs may outweigh the savings.

Questions

Do the prices include VAT?

Each price is shown the way the provider lists it. BizFly states it excludes VAT. Google lists in USD and tax depends on how you pay. Ask each provider before comparing to the last dong.

Google has a promotional price — why isn't it in the example?

The promotion only covers the first year and up to 20 users. From year two you pay the regular price, so the example uses it to reflect the long-run cost.

What if we grow past 20 people?

Starter covers up to 20 personal mailboxes. Beyond that, move to Growth or Business — see the Pricing page. Every plan is still charged per organization, not per user.
