Does MultiUser Mode Contribute to QuickBooks Error PS038?

Yes, in some cases. If multiple users are working on payroll in multi-user mode, there's a chance one person’s actions could interrupt data syncing for another. This could result in stuck paychecks, triggering Error PS038. To reduce this risk, it's recommended to process payroll in single-user mode. This isolates access and ensures better control when updates are being sent or data is being transmitted to Intuit’s servers.
