The short answer

To switch terminals without downtime: confirm there's no lock-in on your current contract, set up the new account and hardware in parallel, test a few live transactions, then cut over during a slow period. Keep the old device until the first deposit from the new one clears.

Step 1: Check your current contract

Before anything, read your existing agreement for term length, early-termination fees and equipment-return rules. Leased hardware must usually be returned. Knowing your exit terms prevents surprise charges and sets your timeline.

Step 2: Set up the new account in parallel

Open your Armour Payments account and configure the new terminal while the old one still runs. Onboarding is quick, and running both in parallel means there's never a gap in your ability to take payments.

Step 3: Test, then cut over

Run a few small live transactions on the new device and confirm they settle correctly. Then switch fully during a quiet hour. Use the terminal setup checklist to verify every payment method works before you rely on it.

Step 4: Confirm funding, then return old hardware

Keep the old terminal until your first deposit from the new account lands and reconciles. Once confirmed, return any leased equipment. Talk to sales and we'll coordinate the timing so you never miss a sale.
