Frequently Asked Questions
Common questions from restaurant owners on Square POS, evaluating Certus AI.
How does Certus integrate with my Square POS?
Certus connects directly to your Square account. It reads your live Item Library, modifiers, prices, and hours, and when a phone order comes in the full ticket fires into Square and your kitchen display just like any other order. No hardware, and no extra fees.
Will Certus work with my existing Square hardware?
Yes. Certus runs on the software side and works with your existing Square Register, Terminal, Stand, and kitchen display. You don't buy new hardware, and your existing phone number stays the same.
What happens if Square goes offline?
Most operators have Certus keep answering and capturing orders during downtime. Orders queue and sync when Square is back, or route to the Certus app and dashboard for your staff. You don't lose a phone order to an outage.
Can Certus process payments?
Yes. Three options: capture the card on the call, send an SMS payment link, or take payment at pickup. You choose what fits your restaurant.
How long does Square setup take?
Same day. Most Certus + Square integrations are live within 24 hours, with about 45 minutes of your time. We handle the menu sync, testing, and call routing.
Does Certus work alongside Square Online?
Yes. Certus handles inbound phone orders, Square Online handles your web and app orders, and both feed the same Square POS, so your kitchen sees one unified queue.
