Tailscale Setup for BizBooks Pro

Skip the manuals and the marketing site. This is the short version of every Tailscale task you'll do while using BizBooks Pro — including the three web URLs that replace the desktop tray icon when it stops cooperating.

Why BizBooks Pro Uses Tailscale

BizBooks Pro is a desktop application that stores your data locally. When you need a second party — usually an accountant — to look at the same books, the data has to travel somewhere. Mailing a database backup is awkward. Cloud-hosting it defeats the privacy benefit of running on-premise. Tailscale solves the problem by creating an encrypted private network between exactly the two machines you choose.

It's free for personal use and very small teams. There's no server in the middle reading the traffic. Both sides install the app, both sides sign in, the work flows over a direct connection.

Get Tailscale Running

1. Visit tailscale.com/download. Pick your operating system (Windows, Mac, mobile, Linux — all available).
2. Run the downloaded installer.
3. When prompted to sign in, use whichever provider you prefer — Google, Microsoft, GitHub, or plain email. The email you choose is the address other people will use to share with you, so pick one you'll remember and that your accountant or teammates already know about.
4. That's the install. Within a few seconds, your computer is visible on your account at login.tailscale.com/admin/machines.

Open Your Desktop to a Collaborator

Use this when you want to let a specific person reach a specific computer of yours. Most common scenario in BizBooks Pro: handing your accountant access to the machine where your books live. The other person needs a free Tailscale account, but does not need to be on your tailnet.

1. Sign into login.tailscale.com/admin/machines.
2. Scroll until you find the device you want to expose — commonly named something like bizbooks-pc or hostdb depending on what you called your computer.
3. At the far right of that row is a three-dot icon — click it.
4. Pick Share... from the dropdown.
5. Enter the email address of the person you want to share with, then press Share. Tailscale handles the invitation email automatically.
6. Wait for them to open the email and click accept. The moment they do, a 1 share indicator appears on your machine's row — that's how you know the share is active.

Add People to Your Network

Sharing a single machine (above) is different from adding a teammate to your tailnet. When you add a person as a user, every Tailscale-equipped device they install becomes part of your network — useful if you've got multiple staff members and several machines to coordinate.

1. Head to login.tailscale.com/admin/users.
2. Click the Invite users button in the upper-right corner of the page.
3. Type their email address. You can paste several at once separated by commas if you're inviting a group.
4. Leave the role on Member for normal teammates. Bump to Admin only if they should have authority to change network settings.
5. Hit Send invite. The invitation lands in their inbox with a join link.
6. Once they install Tailscale and complete the join, their computers begin appearing in your devices list right alongside your own.

Accepting an Inbound Share

The accountant's side of the share workflow above. Your client did the sharing; now you need to accept it.

1. Check your inbox for a message from Tailscale — subject line typically starts with "Accept the shared device".
2. The fastest path is clicking the accept link in that email directly.
3. If you'd rather do it in the admin console: open login.tailscale.com/admin/machines, switch to the Shared with me tab at the top of the page, find the device, and click Accept.
4. Once accepted, the device is reachable from any computer on your tailnet using either its assigned Tailscale name or its Tailscale IP address (both shown on the admin page).

When Things Go Sideways

The Windows tray icon does nothing — clicking it is silent

The most common Tailscale annoyance on Windows. The background service is stuck. Restart it:

1. Open Task Manager (Ctrl+Shift+Esc).
2. Switch to the Details tab.
3. Look for processes named tailscale-ipn.exe and tailscaled.exe. Right-click each and choose End task.
4. Launch Tailscale from the Start menu — the tray icon should now respond when clicked.

If the tray icon refuses to behave even after a fresh start, just don't use it. The web admin console at login.tailscale.com/admin/machines can do everything the tray menu does, and it works in any browser.

My machine shows up but I can't reach it from another computer

• Check that both machines show a green status indicator on the admin page. Green means online and reachable.
• A machine that's been asleep can take 20-30 seconds to reconnect after waking. Wait it out.
• Try the IP address (shown on the admin page) instead of the hostname — DNS resolution sometimes lags behind connectivity.
• Make sure your antivirus or third-party firewall isn't blocking Tailscale's processes.

I shared a computer but my collaborator says nothing arrived

• The invitation comes from support@tailscale.com. Have them peek in Promotions, Updates, or Spam.
• To resend: on your devices page, click ... → Edit sharing... → remove the existing share → add it back. A new email fires.

I can't remember which login I used

Visit login.tailscale.com and try each sign-in method. Tailscale will let you in if the account exists, or tell you it doesn't recognize that login so you can try a different one.
