Corason
A cloud ERP platform that integrates AI to accelerate business decisions

Challenges
現場で繰り返し起きる、3つの課題
業務システムが分かれているほど、入力と確認の手間は増えていきます。

同じ情報を、何度も入力している
人事・会計・在庫・案件が別々のシステムに分かれ、転記と突合に時間がかかる。同じはずの数字がシステムごとに食い違い、どれが正なのか分からなくなる。

数字を出せるのは、詳しい人だけ
画面や項目が複雑で、一覧や集計のたびに特定の担当者へ依頼が集中する。頼んだ側は結果が返ってくるまで判断を止めて待つことになる。

AIに任せたいが、誤った更新が怖い
定型作業を自動化したいが、誰がいつ何を変えたのかを後から追えないと踏み切れない。承認の手順と証跡が無いまま任せることはできない。
