I would estimate as a business that it costs me an additional 2% to accept stablecoins over simple wire / ACH.
For customers with stablecoin balances it's almost always easier to *send* stables:
- instant test txn
- instant settlement
- "flight tracking" via block explorer
- close to 0 fees
But as a receiver, there's a much higher operating burden.
Here's the workflow for accepting wires:
- send invoice to customer via Quickbooks, including wire instructions in PDF
- confirm wire instructions over phone (best practice, but in reality I don't do it)
- customer wires; wait 1-3 days
- funds hit Mercury account and are spendable immediately
- Quickbooks invoice automatically confirmed paid, AR report updated
And here's the stablecoin workflow:
- send invoice to customer via Quickbooks
- send receiving address instructions
- confirm network and request test transaction
- confirm test transaction, request full send
- receive
$USDC transaction to Coinbase
- remit funds to Mercury; wait 1-3 days ("instant" withdrawal costs $100-200)
- manually close Quickbooks invoice as paid
- manually update AR report
- manually tag transaction with customer name (otherwise all transactions are simply from Coinbase)
- and all of this has to be done immediately, otherwise it gets mixed into one big Coinbase balance and it becomes impossible to untangle EOY
So:
- stablecoins practically take the same amount of time (1-3 days)
- they require 4-5 extra manual touchpoints
- they don't automatically reconcile, so someone with less context on the business would have to follow a paper trail vs. simply looking at Quickbooks
I'd guess this overhead is 2% friction over traditional rails, mostly in operating labor and owner mental overhead. The way this has to improve is via a stablecoin-native neobank (of which there are many starting right now).
That neobank has to be at feature parity at Mercury in order for me to switch--a tall order given Mercury is (in my opinion) a best-in-class financial front-end.
I'm beyond pleased with my experience with Mercury and the product geniuses there seem to anticipate every need I have while proactively designing the interface to intercept and eliminate friction.
I'm rooting for a provider built on stablecoin payment rails that can actually take advantage of the speed and transparency of stablecoins while also meeting all the boring reconciliation and accounting needs of a business.
