Hey there everyone!
Here's an idea:
When adding and allocating a receipt, it would be great if there was a "Allocate Full Amount" button that could apply the full receipt amount, much like how the allocation works under the Claim section. Also, have a button so that the system can "Split Allocation Evenly" if there are more than one clients in both the Receipts and Claims sections. This will help users allocate the total amount automatically without having to use calculators and it would prevent small mistakes in having to type the totals for each allocation manually.
