3rd Party Fulfillment/Logistics:
Usually, Carro works with your existing store setup. However, sometimes there's a bit of customization required for Carro to work with your 3PLs. The most common use case is for retailers needing to work with their 3PL system to exclude Carro line items from fulfillment.
If any other issues arise, please contact Carro Support (Intercom or email@example.com) for assistance.
3rd Party Apps (Upsell, Bundling, etc):
All supplier products added to retailer's stores will behave like any other Shopify products. What this means is that you can use partner products with any of your existing apps, it should be as simple as a plug and play.
