1. We still receive the majority of overall sales paid to us as an exporter in fiat usually on a wire transfer or ACH. These are tied to a regular commercial invoice. 
2. Not everyone in other Countries is comfortable to use BTC due to the ever changing approvals by their Governments changing what is ok this month versus a few months back.  
3. I do NOT want payments by credit cards POTENTIAL FOR charge backs, unless it is a long time customer.
4. On one of our websites we ONLY accept BTC via IBEXPAY we do NOT want this transferred to USD, we ONLY want BTC to build up as much as possible, as some smaller suppliers are now starting to accept Lightning for orders. 
5. Our expenses are shown also paid in fiat on one account and one being paid with BTC on another account in this way we can confirm our movement of BTC. Complicated to say the least. However if a business is serious about being circular then this is comes with the territory.
6. We keep records of what the so called price of BTC was at a specific date when a payment was posted when received as BTC. My take is coingecko declares one price, coin market cap another, and so on and so on in the end as far as the IRS, what we declare what we say the price is for a specific transaction is how we close out the books.
7. I do my best to record what the BTC price is at 0900 HST each day.
8. I’m long term for BTC but it is very, very sad that my B2B customers in other Countries are much more interested in BTC than most of the USA B2B and B2C.
9. So in the end our chart of accounts we have some sales that were received as fiat and some as BTC. 
10. Now the fun part when we import we usually have multiple payments going outbound to a supplier. They might be by wire transfer in USD.
11. When we export we might also receive multiple payments if they are received via a zaprite invoice as an example the amount of the transferred value in has to be included in the final calculation of what the profitability is.
12. We also have to pay duty on the goods. How this is included in the profitability and/or selling price is tough.
