Marking Retainer invoice paid through Deluge

Marking Retainer invoice paid through Deluge

Hey Everyone,

We have a scenario where we are collecting deposit payments on our website. Now, in zoho books, we need to create a retainer invoice and mark it as paid automatically using deluge just like we can mark normal invoices as paid.

I have tried the same process as we do for the invoices. Unfortunately, it's not working. Anyone having suggestion on this? Thank you!
