Hi Mandy,

Thanks for using Community Hub.

Yes, you can have two monthly payrolls for the same company on different dates, it's quite common for companies to do this, for example to the 15th if the month and the other company to the 30th / 31st. 

If you change from weekly to monthly, you need to ensure there's no overlap in the pay frequency, you can read more about this here: Lengthen an employee's pay frequency >

It's better to change the frequency within one data set than by setting up a new company.

With regard to pensions, you could have separate schemes for weekly and monthly, but this may be an area you would like to discuss with Sage Technical Support >
