If you change or reconnect your Mercado Pago account in Shopify, fees apply from that moment on. Orders placed before the reconnection keep their fees exactly as they were calculated before the change.
When does the change take effect?
The moment you connect (or reconnect) the Mercado Pago account, Escalafy starts calculating that account's fees for new orders. Orders that already existed before the reconnection are not affected.
Are past orders recalculated?
No. If an order was processed before you reconnected the account, its fees were calculated with the settings in place at that time and they don't change retroactively.
Seeing a date gap with no fees? That's normal if the account was disconnected for a while. Orders from that period have no Mercado Pago fees recorded. If you need it fixed, contact us on WhatsApp with the affected date range.
