How to process a One-Off Pay

One-off pay periods allow a pay period to be run in parallel with an existing pay period and are best used in special situations (e.g. for an adjustment, backpay, termination, or anything outside your normal pay cycle) only.

One-off pay periods are easily recognised by the period number format, which have a suffix of ‘.1’ or ‘.2’ etc. The underlined "Payment Date" may be changed for a one-off pay period; this is relevant with respect to the timing of PAYE for the period.
 
Important: 
If you are processing part of an employees' ordinary income (e.g. a commission), the PAYE will be calculated incorrectly by default as the pay period will be calculated independent from their regular pay period. If you are processing a bonus, cash-up entitlement, final pay, or an employees' entire income over that period, then the PAYE should be calculated correctly.
From home, "Process a Pay" then "Pay Period List". 
Select the underlined "Period" number (e.g. 41 above). This will open a prompt. Select "Yes" and the new one-off pay period will be created with a new line appearing within the table with a suffix (e.g. 213.1 below).
Now return to "Process a Pay", "Time & Income", select the one-off pay period and process your pay as normal.

Important: 
Once the one-off pay period has been processed please navigate back to the "Process a Pay", "Pay Period List", and set the current period back to your most recent pay period.
