LedgerBridge: Non-custodial paperwork for B2B USDT/USDC payments

Hi Product Hunt! I'm Roman, the maker of LedgerBridge. The problem: a stablecoin payment arrives in 40 seconds, but closing it for accounting can take days. A wallet screenshot isn't accepted as proof, and the exchange rate at the time of payment has to be found and calculated by hand. What LedgerBridge does: you give us your own wallet address (we never hold or move funds). We watch the blockchain, wait for network confirmations, record the exchange rate at the block time, and generate a PDF Payment Certificate with the transaction hash, expected vs. received amount, and a SHA-256 hash of the document itself. Honest status: it's a working product on a live server (TRON for USDT, BASE for USDC, site in EN/RU/UA), but I have no paying customers yet. I'm looking for the first 3-5 companies for a free pilot, and I'll set each one up personally. One thing I don't know yet: whether every accountant will accept this certificate. That's the first thing I want to find out in the pilot, so I'd love feedback from anyone who has dealt with crypto payments in accounting.
