Complementary invoice: reward growers with target bonuses at season end

A grower who delivers regularly and in volume all season long deserves more recognition than an occasional supplier. That's exactly what gescom's complementary invoice delivers: a rebate calculated at the end of the period, based on cumulative tonnage targets.

The principle: a target-based bonus, over the whole season

Unlike a standard premium — applied movement by movement, as deliveries come in — a "target" bonus is evaluated across all of a grower's or supplier's deliveries over a given period. For example: beyond 10,000 kg cumulated over the season, a 2 CFA/kg bonus applies to the entire volume delivered. The more a grower has delivered, the bigger the reward — measured over time, not on a single weighing.

A dedicated mechanism, separate from standard invoicing

The complementary invoice doesn't replace your regular invoices — it kicks in afterwards, at the end of the season. The calculation goes back over every movement in the period — including those already invoiced and already paid — to apply the target bonus, then automatically generates a rebate invoice per partner concerned. Each grower gets a clear complementary invoice matching exactly the bonus they earned.

A safe mechanism

Once a rebate is applied to a movement, it's locked: no more changing its price, premiums or partner split. And if a rebate invoice needs to be cancelled, gescom automatically restores the affected movements' cost to what it was before the rebate — nothing to fix by hand.

Why it matters

Rewarding your most loyal growers and suppliers at season end is a real loyalty lever in the rubber and oil palm industries — a strong signal of recognition for those bringing in most of your volume. With the complementary invoice, this season-end bonus is calculated automatically, with no manual rework of a whole season's deliveries.
