Gross-to-net: why every deduction deserves a second look
Between the list price and the cash you bank sit rebates, chargebacks, returns and promotions. Each one was agreed for a reason. Some are paid twice, late or on the wrong basis.
Gross-to-net is the distance between what you invoice and what you keep. In pharmaceuticals, consumer goods and distribution, that distance can be a large share of gross sales. Each deduction in it was agreed for a reason. The question is whether each one was paid for that reason, once, and at the right amount.
What sits between gross and net
- Rebates to distributors, retailers, insurers or buying groups
- Chargebacks when a wholesaler sells at a contract price below what it paid you
- Returns of expired, damaged or unsold goods
- Promotional allowances for displays, listings and campaigns
- Prompt-payment and cash discounts
- Deductions customers simply take off their payments
Five places deductions go wrong
Paid twice
The same chargeback claimed through two channels, or a rebate paid once by credit note and again by bank transfer. Matching claims to contracts, invoices and earlier credits finds these quickly.
Paid on the wrong basis
A rebate meant to be calculated on net sales is calculated on gross. A volume tier counts units that were later returned. Each error is small; across a year of claims it is not.
Paid after the contract ended
Contract prices and rebate agreements have end dates. Claims against expired terms should be rejected, and often aren't.
Taken without agreement
Customers deduct promotional or penalty amounts from their payments. Without a match to an approved promotion, these are disputes waiting to be raised.
Accrued too much, or too little
Accruals that never reconcile to actual claims distort margin by month and by product. Over-accruals released at year end hide the real trend.
The data you need
| Source | What it tells you |
|---|---|
| Invoices and credit notes | What was billed and what was given back |
| Contracts and price agreements | What each customer is entitled to |
| Claims and chargeback files | What was asked for, and when |
| Payments and remittances | What was actually deducted |
Where to start
Start with the deduction type that is largest and least automated. For most companies that is chargebacks or customer deductions. Match twelve months of claims to the contract in force on the date of sale. The mismatches are your first list of recoveries.
A deduction is a promise kept. A deduction nobody checked is a promise kept twice.
Our gross-to-net health check does exactly this, and every finding arrives with the claim, the contract clause and the value behind it.
