Alternatives to Smile.io

Qonto

commerce

Strongest fit on feature parity. The most direct functional swap. Shares commerce feature signature, comparable workflows, and a similar audit-score band — switch costs are usually lowest here.

ShipStation

commerce

Wider scope, slightly different focus. Wider feature surface than the source app's focus area. Useful if you're shopping commerce alongside adjacent capabilities you'd otherwise integrate separately.

Pennylane

commerce

Established alternative with audit-grade listing. Established option with the rating + review depth to be vendor-evaluated. Best when running this category at scale and you can't afford early-stage product surprises.
