A flow is not a connector, and it is not the traffic that happens to move in a month. It is one business event carried between two systems: orders into finance, a new hire into payroll, a shipment into the ERP.
On Ngentix a flow is one source connected to one destination. Both ends are translated into the same canonical model, so the record means the same thing on both sides. You turn a flow on. Ngentix keeps the translation correct when either system changes.
The price is per flow, because the thing being kept true is the business event, not a seat and not a volume of records.
