What it is
A Rate is the price for a unit of work — per hour, per ton, per load, per mile. An Add-On is an extra line on the invoice or pay statement (toll, demurrage, layover, truck commission). A Fuel Surcharge is a Rate that adjusts to fuel prices on a schedule.Why it matters
Rates flow into every invoice and every pay statement. A misapplied rate is a billing dispute. A missing add-on is unbilled revenue. A broken fuel surcharge is the same mistake repeated across hundreds of loads.How Tread models it
Rates apply by Customer, by Material, by Site, by Equipment Type, or globally. Tread looks up the most specific match. Fuel surcharge has three components. This is the part first-time admins get wrong.- Price index — the fuel price source you key off (DOE national average, regional, custom).
- Schedule — the table mapping fuel price bands to a surcharge percentage or per-mile rate.
- Application — where the surcharge applies (which Customers, which lanes, on top of what base rate).
| Component | Lives on | Example |
|---|---|---|
| Rate | Customer / Material / Lane | $4.25 per ton, Pit A → Site B |
| Add-On | Customer or Vendor | $50 demurrage after 30 min |
| Fuel surcharge — index | Platform | DOE West Coast |
| Fuel surcharge — schedule | Customer | 3.75 = 4% |
| Fuel surcharge — application | Customer | Apply on freight only |
