Katalyst OS
Top pickBuilt for the modifier complexity, delivery-heavy mix, and Friday-night surge that pizza operations actually face. Native third-party marketplace integration (DoorDash, Uber Eats, Grubhub) flows orders into the same KDS as direct online ordering — no tablet stack. Interchange-plus payment processing adds 4–7× the per-order margin of bundled rates on direct orders.
In Boston: Katalyst was built in Massachusetts — the founders run their own restaurants in MA, and the tax/compliance handling for the 6.25% + 0.75% meals tax plus the MA labor laws is built in from day one rather than configured per location.
Best for: Pizzerias of any size that take direct delivery seriously
