approvisionner

A common business/logistics verb meaning to supply or stock — a store, a market, a bank account (approvisionner un compte) — with goods, resources, or funds; the pronominal s'approvisionner means to stock up or get one's supplies.

• Le magasin s'approvisionne chaque semaine chez ce producteur. — The store stocks up from this producer every week.
• Il faut approvisionner le compte avant le prélèvement. — The account needs to be funded before the direct debit.
• Cette région approvisionne toute la ville en eau. — This region supplies the whole city with water.

Learners sometimes reach for the more basic fournir instead — approvisionner specifically implies an ongoing, regular supply relationship (a store restocking, a region supplying water), not a one-off act of providing something.
