Software for the deal side of TV: the discounts, baselines and money shares that decide what a budget actually buys.
Media buying software earns its keep in the deal maths: seller discounts that multiply instead of adding, discount tiers that depend on the budget they change, CPP quoted on one baseline and billed on another. Get one of those wrong and the delivery gap appears months later, with no line to point at.
Five mechanics decide whether the buy delivers what the plan promised. All of them run inside Tilsim TV Budgeting on the same frozen core the plan was built on — the compounding ladder, the first of them, is open to try in the wTRP → budget calculator.
| Calculation | Why it matters | Where it breaks in spreadsheets |
|---|---|---|
| Multiplying discount ladders | Seller discounts compound: 20% and 10% make 28%, never 30%. | Discounts summed in a single cell; the 2% error travels into CPP. |
| Budget-dependent tiers | The discount tier depends on the budget — which the discount itself changes. Boundary cases need a fixed iteration rule. | Circular reference «resolved» by hand, differently each month. |
| CPP baselines | A CPP quoted on 30″ ratings must not be billed on duration-weighted TRP without the coefficient. | Mixed baselines between the deal sheet and the delivery sheet. |
| Prime / off-prime money share | The share of money and the share of ratings move differently between dayparts — the deal fixes one, delivery reports the other. | One share used for both sides of the reconciliation. |
| Plan ↔ fact reconciliation | The buy must be checkable against the plan line by line, coefficient by coefficient. | Plan and fact live in different files with different maths. |
One core, two products around it — planning the money and reading the audience.
Encodes negotiated discount ladders per seller, resolves budget-dependent tiers by iteration, and keeps CPP on one declared baseline — so the number agreed in the deal is the number the delivery is judged against. Measured <0.01% deviation from the reference model — how that figure is produced is described in the methodology.
Full product page →Reads the actual delivery from the Nielsen feed — spots, ratings, reach — against the plan, so reconciliation is a report, not an argument. The client sees the same numbers in a portal of their own.
Full product page →No — it can only make the gap visible sooner. If the plan summed discounts that multiply, the buy will underdeliver against it no matter how well the deals are executed. That is why Tilsim runs planning and buying maths on one core instead of reconciling two tools after the fact. What the plan itself has to compute before the deal starts is set out under media planning software.
The discount ladder. It is the smallest formula with the biggest compounding error, it changes per seller and per year, and it is the first thing a seller's own sheet computes correctly when yours does not.
From your own deals: rate cards, negotiated ladders and seasonal indices are loaded per channel and per seller. Tilsim supplies the mechanics and the parity discipline — the market data stays yours.
The arithmetic behind the product, explained step by step.
The fastest way to judge buying software is one seller, one ladder, one campaign — run through the core next to your own sheet, coefficient by coefficient.
