As Amazon and Shopify both provide data on a settlement basis, A2X mirrors this treatment when compiling our settlement and payout data. We always consolidate the data on sales, shipping revenues, fees and reserved balances into one, easy-to-reconcile invoice or journal. This follows the general advice from HMRC on supplies made by third party agents.
