In desperate need to find delivery scheduling plugin for 4.3 version

1 week ago
As title suggests, i need to find plugin for delivery schedule, also plugin for custom PDF invoices. Up until weekend i've been using ones from resanehlab ( but they (i guess) have troubles with site or what not and i can't reach them through emails (full mailbox warning). Their plugins verify license in real time and since i guess they have issues with server neither of plugins work. I got clients using these plugins and have to replace them asap in order for them to continue normal working. Any help is more than welcome!
