Head to head
Square vs Zeller
Which card machine keeps more in your pocket? We rank both purely on estimated card costs — then weigh contract and settlement. Ranked on cost, with no paid placements.
How Compayr makes money: some providers pay Compayr when a merchant switches via our links — a one-off amount, an ongoing share while you process, or both. Others pay us nothing. This never affects rankings, which are ordered purely on lowest estimated card acceptance cost. How we compare
The "Compayr pick" is editorial — decided by the weighted side-by-side comparison below, led by lowest estimated card cost. It cannot be bought or influenced by any provider. How we compare
