Build Your Own Google Workspace

As they say, time is money, but if you want to take the time in order to save some money, you can gain access to most of the Google Workspace/G Suite products yourself. It may not be comprehensive enough for your needs, but this is how to start:

1) Sign up for a free Gmail account – this will automatically grant access to features like Google
Docs, Slides and Sheets. Try your company name with the Gmail suffix. If taken, modify it until
you arrive at a unique address. You will mostly use this as the login for your Google account.
It will not be seen as your public facing email. This step also gives you 15GB of storage space.

2) Direct your company email to your Gmail account. This gives you the ability to send and receive
company emails through Gmail. However, to get rid of the ‘@gmail’, you have to do some extra work.
Your domain registrar gives you the option of creating an email address on your own domain.
Depending on your how you got your domain: a web host will generally include basic email for free,
but a domain registrar, like GoDaddy, will most likely charge you for setting up email. Still, that
nominal fee should be a lot cheaper than Google Workspace.

This gives you the lion’s share of Google Workspace for free. It has its limitations – for example, the free 15GB of storage can get used up easily. If your business grows the way most companies want to grow, it will soon be advisable to upgrade to a paid account. The good news is, that with that kind of growth, you should be able to afford the cost better.
