Check please below sentences. Dear [Name], I sent invoice before. We agreed with this condition : 1st payment within 5 days from the date of invoice: 15% - $6000; balance payment – 85% - $34000 upon receipt of payment by Transnet from the customer and term of balance payment is within 45days after leaving loaded containers from Korsakov(a name of port). As the previous agreement, we issued this invoice. But, 1st payment date already is passed, so we expect the balance payment will be sent to us by the end of the December, including 1st payment $6,000. Please check our invoice, we are waiting your reply. Best regard. Are you understand what i wrote, Aurora?

There were a couple of sentences which were a bit confusing. As much as you can, when writing a letter and you need to enumarate some details, do away with writing one long sentence for it. Instead you should do it like this. \"We agreed with the following conditions:                a.) 1st payment within 5 days from the date of invoice: 15% - $6000; balance payment &#8211.                b.) 85% - $34000 upon receipt of payment by Transnet from the customer.                c.)  the term of balance payment is within 45 days after delivery  of loaded containers from Korsakov(a name of port).\"   If you write in this way, it makes it easier to understand and read whatever you are enumerating. ^^   T.
