Hi Patricia,
ERP systems generally have extensive integration capabilities you can use to connect to integrate with Laserfiche. This IFS Cloud Overview page says:
Connect and extend out of the box
Connect and extend your IFS Cloud solution to your broader application landscape as well as a wide variety of platforms, tools, data sources, and more inside and outside your business. Whether you use a low-code platform to extend your solution with specific task apps or pull data to use in a machine learning model, your core software is built to connect and extend right out of the box. IFS Cloud is built around standards-based REST APIs, so everything you can do in IFS Cloud you can also do through our open APIs, making it simpler for you.
That makes me confident integrating with Laserfiche Cloud is possible. You can use Laserfiche Cloud Web Request Rules to call those IFS REST APIs, and IFS Cloud can surely call Laserfiche's own REST APIs (see also the Laserfiche Developer Center). There are other integration methods available as well, though the REST APIs are usually the best option if they can address your use case.
If you can provide more information on the business use cases and functionality you imagine the integration addressing, we can discuss more specific guidance on the technical approach.
