The result of your sales with 成果

三ツ星カラーズ » Volume 8 » Page 85

Sacchan’s mother has an overstock of bananas at her fruit shop, so she gives them to Sacchan and her friends to sell around the neighborhood. Later, Sacchan returns having sold all the bananas.

(かあ)さん:
「じゃあ()()げはキミたちの成果(せいか)として(あた)えよう」
“Then I'll give you the sales as your reward.”
「ごほうびだ」
“Consider it a bonus.”

Translated here as “reward”, 成果(せいか) refers to the result of the work the girls put into selling the balances.
