We only require an email address for consumers, but will soon allow for anon accounts.

Businesses onboard with an LSP (lightning service provider) of their choice and those service providers generally require KYB. Oshi does not ask for any sensitive business information.

There's a lot of nuance when it comes to which LSP is better fit for vendors. If a business wants dollar convertibility, then OpenNode is likely the best since they charge a 1% flat rate whether you receive bitcoin-only or want to convert a portion of that to dollars.

For bitcoin-only, for businesses without any technical expertise, I recommend Ibex as their fees are cheaper than OpenNode for bitcoin-only but more expensive for dollar convertibility. Ibex really gives additional incentive (in the form of lower fees) for receiving and holding the bitcoin 👍

If they're looking for a POS-like solution, Ibex really shines here with IbexPay. We try to get businesses set up with both Oshi and a POS solution if they're ready for that.

For businesses in El Salvador, we recommend Bitcoin Beach Wallet. It's so easy to get set up. All they need to do is paste their bitcoin beach wallet username to connect with Oshi.

More technical/self-sovereign businesses (very rare) can connect their BTCPay server to Oshi using their Invoice API key.

I don't recommend the business owner simply using a phone wallet because that would generally require the owner to be present when the transaction is taking place. LNURL and static invoices are nice, but not all wallets support it at this time. Will definitely be exploring LNURL more, but at this time I prefer bolt 11.

Taxes really aren't all that different for a business. If they receive a payment in bitcoin, the value of that product or service (in dollars) at the time of sale is reportable as income just like any other business transaction. The only caveat is that if they choose to trade the bitcoin for dollars or use it for business expenses, there would be a taxable implication on the capital gain/loss. Most businesses choose to hold the bitcoin and 'roll the dice' so to speak. What's a few coffees, beers, or burgers sold each week for bitcoin? In the grand scheme of things, that's a very small amount of their total sales and an asymmetric tradeoff to bring in more business (with a massive upside potential).

Paying with bitcoin is getting easier and easier. There's still quite a bit of friction in getting a lightning-enabled wallet, but we believe the satsback incentives and the local commerce experience will be enough at this stage for people to get started. As more and more payment providers like Strike, CashApp, and others make it super easy to send a lightning txn, Oshi will be well positioned to accelerate this trend by providing the best local deals all on the same platform. Shop local, earn free bitcoin. I'm not sure many people will be able to turn that down as it becomes easier.
