Stripe rounds the Stripe fee to the nearest unit (e.g., cents). For example, if the fee is 0.025, Stripe will round up to 0.03. If the fee is 0.024, Stripe will round down to 0.02.
ACH fees have a floor, so if we were to round the fee to 0, we would instead round it to 1 cent.
If you’re looking at how Stripe is rounding tax amounts in invoices, it’s done at the invoice item level to the smallest currency unit before summing across the entire invoice.
