Keeping QuickBooks Desktop Syncing Overnight and on Weekends

Web Connector syncs fine during the day, then Monday morning there's a weekend of orders that never reached QuickBooks. It's one of the most common complaints — and almost always one of these causes.

Why it stops when nobody's around

• The PC went to sleep. Windows' default power settings put desktops to sleep after a while.
• Windows Update restarted the PC. After a restart, Web Connector and QuickBooks don't reopen on their own unless you set them to.
• Someone signed out. Web Connector runs inside a signed-in Windows session.
• A pop-up is waiting. QuickBooks update notices, backup reminders and permission prompts block syncing until someone clicks them.
• Power or internet dropped and the PC didn't come back cleanly.

The always-on checklist

1. Sleep: Never. Settings → System → Power & sleep → Sleep: Never.
2. Restart on power loss. In the PC's BIOS, enable Restore on AC power loss if available.
3. Start Web Connector with Windows. Add it to the Startup folder — see Auto-Run setup.
4. Schedule updates. Set Windows active hours and install updates during the week, not just before a weekend.
5. Turn off QuickBooks reminders you don't need, such as automatic update prompts and backup reminders on that machine.
6. Allow access when QuickBooks is closed, in Integrated Applications preferences.
7. Use a UPS (battery backup) for the QuickBooks PC if power is unreliable.

Get told when it stops

No checklist prevents everything. The best safety net is an alert: SyncGuard notices within minutes when the PC goes offline or Web Connector stops syncing, and emails or texts you — even at 2 a.m. on a Saturday, if you want it to.
