What an integration covers
Every supported POS integration includes:
- Item and batch flow from S4 Back Office to the POS
- Cost, price, and status flag flow
- Frequent shopper pricing and electronic couponing
- Promotional priority handling at the lane
- Active and pending batch visibility back to S4
Specific feature support varies by POS platform — for example, ISS45 supports advanced promotions that not every other platform exposes. If you have a specific promotional pattern you’re trying to run and want to verify support on your POS, ask us.
