Why FIFO costing matters

Most Amazon tools use average cost accounting — which means your profit figures are always slightly wrong. SellerToolKit is the only tool that uses true FIFO (First In, First Out) cost tracking, giving you the exact profit on every single sale based on the actual cost of the unit sold. Built by Amazon sellers who were frustrated by inaccurate numbers.

★★★★★

"Just got a refund from Amazon for reimbursements overdue £208.44 which i may have missed. STK is worth the cost for the reimbursements feature alone.Great piece of Kit!"

★★★★★

"I don't know any other software in this space that develops feature requests from it's user base at the rate Norm Rogers does.The most valuable piece of software any Amazon business needs."

"STK is the best P&L tool I worked with. Can't recommend it highly enough!"

Vlad CokiAmazon FBA Seller
★★★★★

"I moved from XXXXXX to STK and the difference was huge. STK is very reliable in terms of the numbers it generates but also the many features."

"To those who are undecided, this is undoubtedly the one tool that revolutionized the way i looked at my Amazon business…"

Ben KennyAmazon FBA Seller
★★★★★

"Hey all,Just want to highlight what a fantastic repricer STK is to everyone. I've recently moved from XXXXX(had for over a year) as got bought in to the 'maximise profits' promise and realise now how much of a fools gold this is. ISTK has been an eye opener for me and has proved to be a beneficial move, my only regret is not moving sooner. If anyone is on the fence I strongly recommend you make the jump in this direction."

"Stk overall is great and I couldn't work as efficiently without it."

Richard KimbellAmazon FBA Seller
★★★★★

"It's been a while since I've tried the STK out and I can only say how impressive it is!!! Amazing features and great details, incredible support from Norm from A-Z!!! The auto reconciles feature is one of the best things brought up on the market, as there is no need to use a third-party company to reconcile the missing/lost or not reimbursed items by Amazon. I highly recommend it for those who haven't signed up yet!!!"
