Our MIS & Reporting service reports contribution, stock cover and storage cost by product every month.
In Seller Central, the fee preview for each product shows the referral, closing, weight-handling and FBA fulfilment fees. Your settlement reports show what was actually charged. Enter all fees excluding GST.
FBA charges storage on every unit held in the fulfilment centre, whether it sells or not. The extra Prime and Buy Box sales must cover that storage before FBA earns more than shipping the orders yourself.
Use the cm option and enter the packed length, breadth and height. The calculator divides L × B × H in cm by 28,316.8466 to get cubic feet.
Stock that has sat in the fulfilment centre long enough to attract an aged-inventory surcharge on top of the monthly storage fee. Enter the combined monthly charge per cubic foot from your inventory reports.
It depends on your figures. The calculator compares holding until it sells, a one-off discount to clear it in a month, and a removal order with offline liquidation, a unit.
We keep books, file GST and TDS returns and prepare monthly MIS for D2C and marketplace sellers. Share your figures and we will walk you through what we find.
