All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
If the documents submitted to the accounting team have nothing to do with usurious financing, but rather are for documenting Halal (lawful) goods and shipments - which is what appears to be the case - then there is nothing wrong with your work in submitting those documents, even if the accounting team may use them for the mentioned financing, because this assistance is neither direct nor intended, so it is not forbidden.
However, if the documents are requested for the sake of usurious financing that cannot be completed without them, it is forbidden to submit them in that case due to the prohibition of cooperating in sin, as Allah Almighty says (what means):{...Cooperate with one another in goodness and righteousness, and do not cooperate in sin and transgression...} [Quran 5:2].
Lastly, if a person limits themselves to what is permissible in that company, such that they do not engage in anything forbidden, nor directly or intentionally assist in it, then there is no harm in working there. Otherwise, it is impermissible.
Allah knows best.
