Season ticket
The short answer
One waste transfer note covering repeated identical transfers between the same parties, valid for up to twelve months, so a weekly round is not twelve notes a quarter.
In practice
Identical is the catch. Same parties, same description, same waste, same route. A load that differs needs its own note, and a season ticket stretched to cover something it does not describe is no note at all.
Where LoadSnap touches it
LoadSnap enforces the eligibility rules rather than assuming them.
