Frequently Asked Questions
Got Questions? We’ve Got Answers.
You may always email us directly at [email protected] if your question is not found within our FAQ below.
Can you handle EDI document?
Yes, we have a BizTalk Server with all the X12 schemas available meaning we can do mapping and orchestrations for any EDI needs you may have.
Is this Cloud or on-premise?
We operate our own on-site data center within the warehouse, built on two high-end servers configured in a replication failover setup, ensuring high reliability and minimal downtime. However we are fully capable of hosting this on Azure or AWS for any custom requirements.
How many Orders, Users, etc am I allowed to have?
New objects only occupy small amounts of database space and at the moment we have not placed any restrictions on this.
Can my Clients have access to view their Orders or manually enter Orders?
Yes, you can create User accounts for your Clients to allow them to view their Orders and Inventory. They can also manage Inventory or create Orders depending on how much access you wish to give them.
Does this support multiple Locations?
Yes, you can create as many Warehouses as you need and typically each Client you on-board would have their own Warehouse created to separate Orders, Inventory, etc despite being physically in one building. You have a lot of flexibility here.
