Dear Sarajharindu,
Greetings!
Based on your project description, here are my answers (please note that the alignment for this message may be distorted):
I am well versed with Quickbooks. Moreover, with me previously working in Bax Global, a freight forwarding company, I can assist you with the processing of order, invoices (Quickbooks), purchase orders, customer email inquiries, track and trace of product return requests and so much more. I am available at the hours you have stated.
With that said, hope you will consider my application. Thanking you in advance for your kind consideration.
Thanks & Regards,
Rina
