Early termination fees are the single biggest reason merchants stay stuck with bad processors. ETFs come in two flavors: flat ($295–$500, common on legacy ISO accounts) and liquidated damages (the remaining months of the contract, common on Toast and some Clover ISOs).
What to look for in your contract: search for 'early termination', 'cancellation fee', 'liquidated damages', or 'ETF'. The ETF is usually buried in the merchant agreement — not the rate sheet. Always get this in writing before signing.
How to avoid one: choose month-to-month processors (Stripe, Square, Helcim, Stax, Dharma, National Processing). Their pricing is competitive and there's zero penalty for leaving.
