Hi @David Lockwood
If you're using QBO Payroll, your options are limited to those that QBO integrates with.
A quick read shows that Standard Payroll is NEST only.
Advanced Payroll (https://quickbooks.intuit.com/uk/payroll/advanced/) integrates with NEST, Smart Pensions, The People's Pension, Aviva and NOW: Pensions.
I don't use QBO Payroll so can't comment on the function of the integration (& please don't take this as a recommendation) but I use Smart Pension & the Direct Debits are automatic.
DD is monthly.
I get an email from them to confirm each batch submission with the amount (for checking if necessary).
I get an email from them around the 2nd of each month confirming the monthly total (& asking for any unsubmitted deductions to be submitted).
DD is taken around the 7th-10th of each month (again, an email to confirm 2-3 days in advance).
Hope this helps.
