While major hotels and some larger restaurants accept credit or debit cards, cash (Nicaraguan Córdoba - NIO or US Dollars - USD) is strictly essential for local eateries, small shops, independent guides, and transport.
Make sure to carry enough cash, especially if you are heading to more remote and beautiful areas where card machines and ATMs are non-existent.
CRITICAL TIP FOR PAYING IN US DOLLARS:
You can pay in both Córdobas and US Dollars across the island, but there is a strict rule for USD: Bills must be in near-perfect condition. Local businesses will absolutely reject dollar bills that are torn, overly dirty, stained with ink or paint, or have any type of stamps on them.
(Watch out: When withdrawing USD from local ATMs, always check your bills immediately. ATMs sometimes dispense damaged notes that will not be accepted by merchants!)

Exchange Rates & Getting Change
If you pay for a meal, a tour, or transport using US Dollars, expect to receive your change in Nicaraguan Córdobas. Local businesses use their own standard exchange rates, which typically range between 36.00, 36.50, or 37.00 Córdobas per US Dollar, depending on the establishment.
While this rate might be slightly lower than the official bank rate, it is extremely convenient. There is no need to visit a bank just to exchange small amounts of cash—just remember to use small bills ($10 or $20) for small purchases!
