Right now someone has to create credit notes for periodic leases by hand every time. That's slow, easy to get wrong, and it means the Lease and Payment records can drift out of sync. We want to automate it, without touching the bits that are deliberately manual.
What's in
Periodic lease credit notes, both full month and partial month, posted automatically to the Lease tab and the Payment tab (principal, interest, finance).
What's out
Recharge (approval) credit notes and COVID-19 relief credits. Those stay manual, no change.
How it works
There's a new Credit button on the Lease tab. The user enters the Contract ID, picks the period they want credited, hits Credit, and the system asks whether it's a full or partial month (F or P).
Full month: we just reverse the lot. Opposite-sign entries for the lease rental amounts on the Lease tab, and for principal, interest and finance on the Payment tab.
Partial month: we show the rental start and end dates for that period, then ask for a Credit From date. It has to sit inside the rental period. From there we work out how many days are in the rental month, how many days we're crediting (credit date through to rental end date, inclusive), then pro-rate it: monthly amount divided by days in month gives the daily rate, times credit days gives the credit. Same as above, opposite-sign entries go to both tabs, with principal plus interest still equalling finance.
Validation and safety nets
Standard Catch-e prompts, so "OK to Save?" and "Cancel". Every credit needs to stay auditable and traceable back to the original lease period, and the maths has to line up with the existing lease schedule data.
Reporting and accounting
Credits show up correctly in lease schedules, sync properly with payment records, and finance integrity holds (principal + interest = finance).
Done when
A user can raise a full or partial periodic lease credit in one guided flow, both tabs update automatically and stay consistent, recharge and COVID credits behave exactly as they do today, and nobody has to touch a standard periodic lease credit note by hand again.
