Social security, A1 & CoC
One day abroad can trigger dual contributions; an A1 or CoC proves where they stay payable.
Every business trip, assignment, and work-from-anywhere trip carries risks. WorkFlex solves the compliance automatically in one platform. Our experts write the rules, AI manages the workflow, and we're on the ground wherever your people go.

A single day of work in another country can trigger A1s, posted worker filings, visa rules and tax exposure. And every one of them is the employer's job to get right.
One day abroad can trigger dual contributions; an A1 or CoC proves where they stay payable.
