Hello Sjsheen
To confirm the situation you have been reimbursed by your client but you need to create an invoice for that and record as fees for services rendered.
It would be a case of creating a new invoice if you need to physically send them an invoice and you can create a service item for fees for services rendered in products and services if you need to.Alternatively if you do not need to invoice you can use the + symbol in the top left and then bank deposit>add funds to this deposit
If you have any questions or were looking to record this differently just reply back here
