Straight answers before you move inventory.

Short, practical guides written by an operator, not a content team. Each one answers one question a founder asks before choosing a 3PL, FBA or doing it themselves, with real numbers from Marcana's published rates.

Decision guide

FBA prep after January 2026: what changed and what you have to do now

Amazon used to label and bag units for a fee when they arrived unprepped. Since January 1, 2026 it does not. Units must arrive at Amazon already prepped, and improperly prepped inventory can face receiving problems and may not be eligible for reimbursement.
