Hi, I would like to open e-residency based limited company in Estonia doing the drop-shipping and would need some info around corporate accounting. There would 1000 sales per month at minimum - each sales has 2 transactions in PayPal (1 from the buyer to me and 1 from me to the supplier. Hereby the difference between transactions is profit excluding costs and corporate tax) I have 2 questions: 1) Does an accountant need to track each transaction or is it enough for corporate accounting only to have reconciliation month of inbound/outbound? 2) Should the invoice have both transaction in the summary?
