The preposition of accordance (zgodnie z)

Expressing Accordance: Zgodnie z

When you need to express that an action follows specific rules, standards, or guidelines—translating to "according to" or "in accordance with"—use the phrase zgodnie z.

Because this phrase ends with the preposition z (with), the noun or noun phrase that immediately follows it must always take the Instrumental case.

All documentation must be prepared in accordance with the company's policy.
Cała dokumentacja musi być przygotowana zgodnie z polityką firmy.

In the context of corporate audits and compliance, you will frequently refer to multiple rules at once. Remember that plural nouns in the Instrumental case take the ending -ami, while plural adjectives take -ymi or -imi.
