A discount schedule is a set of quantity or term tiers that lowers the unit price automatically as a customer buys more, so volume pricing follows policy, not each rep's judgment.
A worked example
An illustration with round numbers. A part lists at $10. The schedule has three tiers: 1 to 100 units at $10, 101 to 200 at $9 (10% off), and 201 and up at $8 (20% off). A customer orders 250. Volume: all 250 units take the $8 tier price, $2,000. Slab: the first 100 at $10, the next 100 at $9 and the last 50 at $8, $2,300. Same order, same tiers, $300 apart. Volume pricing also creates a cliff: 200 units cost $1,800, but 201 units cost $1,608, so a customer pays less by buying more. Slab has no cliff; the total always rises with quantity.
Write the schedule down, then guard the exceptions
A schedule turns volume pricing into policy: every rep gets the same price at the same quantity, and nobody has to remember the breakpoints. The two decisions are Volume or Slab, and where the breakpoints sit; set them where your costs or margins actually change. Then route anything beyond the schedule, such as an extra line or header discount, to an approval, so exceptions are visible and reportable. If a tier price doesn't appear on a Kugamon quote, check three things: the product uses the Cost Pricing Method, the schedule isn't Active, or the quote uses a different Price Book. A customer with Account Pricing gets the negotiated price instead of the tier, by design. The Products and pricing reference sets out the full hierarchy.
In Salesforce
Sales Cloud has a single Discount field on each Opportunity Product, typed by hand, with no tiers. Salesforce CPQ adds SBQQ__DiscountSchedule__c, which holds volume or term discount tiers, applied either as a range (the tier the quantity reaches prices every unit) or as slabs (each tier prices only its own units). In Revenue Cloud Advanced the equivalent is PriceAdjustmentSchedule, part of Salesforce Pricing alongside pricing procedures. On a move from Salesforce CPQ, partner migration tools handle basic schedules, but advanced ones still need manual handling.
How Kugamon handles it
Kugamon's discount schedule is Tiered Pricing, which Kugamon's documentation defines as a pre-defined Discount Schedule. You create it from the Product's Tiered Pricing related list: name it, pick a Price Book and a Type (Volume or Slab), add tiers with a Quantity and a Discount (%) that calculates each Tier Price, then [Save All Tiers] and [Activate]. Volume uses the Tier Price of the tier the quantity falls in for every unit; Slab prices the quantity across all tiers at and below it. A separate set of tiers can be added by Service Term. Tiered Pricing applies only to the List Pricing Method, only one schedule can be Active per Price Book, and Account Pricing outranks it in the pricing hierarchy.
