Custom-built FBA operations software — restock planning, warehouse scanning, labels and carrier booking, repricing, wholesale orders and the money side — connected to whatever software already runs your company's stock.
We built and operate a complete back office for an Amazon FBA seller doing about 750 orders a day (up to ~980) across about 380 active SKUs. It replaced a patchwork of spreadsheets, Seller Central tabs and a third-party repricer with one application that the owner uses from a desktop, the warehouse uses from a tablet, and management checks from a phone. In September it also took on wholesale orders and a second marketplace that sells from the same stock.
Each one used to live in a different tab, spreadsheet or tool. Now they share one screen and one source of truth.
Sales pace, FBA stock, inbound, days of cover, Amazon's own recommendation and your warehouse availability side by side, including units held for the other marketplace (per component, for multi-item sets). Quantities snap to box multiples automatically, keeping Amazon's placement fee at $0.
The warehouse gets the pick list on a tablet and packing is scan-checked into boxes with a barcode gun. Expiry dates are captured, and a missing one stops the shipment before it's sent, not after Amazon's receiving dock.
Inbound plan created, placement confirmed, carrier quoted and booked, FBA + carrier labels merged and printed to a 4×6 thermal — one button each, from the same screen the packer already has. All placements came in at $0.
Your rules, enforced around the clock. The main engine matches the lowest FBA rival and never chases merchant-fulfilled offers; with no FBA rival, it prices off the lowest merchant offer plus a set margin. It never goes below your floor (a SKU with no floor isn't repriced, it's flagged), skips fee dead zones and touches only SKUs that have stock. Selected SKUs can instead follow one chosen rival listing, checked hourly. Every price move is logged with its reason and the rival's name.
Expenses, supplier payments and money in: amount, category, done — entered from a phone, recorded instantly. Buyer and supplier balances net out on their own.
A listing loses "buyable", a SKU will run out before a shipment could land, a rival prices under your floor — one feed instead of fifty emails.
The price list goes out as a locked spreadsheet and the buyer's order is read back and checked line by line. Invoice PDF and email, UPS label bought in the app, delivery added to the invoice. One unpaid order holds all of that buyer's shipments until the money arrives, unpaid invoices are flagged red after 48 hours, and the packing screen shows pay-then-ship status in color.
Supplier invoice PDFs are read, checked by a person and posted as stock receipts, no retyping. New barcodes are captured with a scanner straight onto the item card.
A second marketplace sells from the same warehouse stock. Its listing quantities come from stock minus unshipped orders and a small buffer, any product can be paused, every variant at once, and shipped orders are written off automatically once a day, after the day's shipping — 4,000+ since Sep 11.
A live screen shows who is scanning or shipping, and software updates wait until nobody is mid-shipment. A walk sheet lists what to bring from overflow storage for the next two weeks of sales.
Every business already has a system of record — an ERP, an inventory manager, an accounting package, sometimes a home-grown one. We don't replace it; we plug into it. Here it runs both ways with the business's existing stock and accounting system: when a shipment leaves for Amazon, stock is written down automatically; when a shipment is cancelled or the warehouse packs short, it's corrected; supplier invoices arrive as stock receipts; expenses and payments land in it the moment they're entered. The integration is built for your system, not a lowest-common-denominator connector, and the same approach can connect to:
