Hello Nishit thats great to hear you have had a wonderfull holiday!
Please let us know if you could manage port in functionality as we awating for your report.
For orders it is ok when customer subit a request for mutiple numbers but notification should be only for one request and not each number;
So if customer orders 10 numbers per one order then there should be one notication with 10 numbers listed.
Or if on table there should be an order and in dropdown we can see 10 numbers in the order.
Please make it all very neet and user frienly.
Will wait for your updates and guide you if anything wrong.
For Custom Features please let us now more details what you have done from that job as we will need to combine these budgets.
