A BTC-backed stablecoin such as DOC or ZUSD would be a better fit for this use-case than BTC, unless the company plans on holding the BTC for many years without needing to sell in the interim (since BTC is likely to decrease in value during that time period, which would result in realized losses -- some businesses could afford to eat those losses, but many could not). Alternatively, the company could buy BTC and offset any losses with derivatives, although imo this has more counterparty risk than the BTC-backed stablecoins would have.
