Plan replenishment

    Know exactly what to ship today.

    Drop in the Inventory Ledger you already pull, and Unilytic hands back a send list: every SKU sorted into out-of-stock, low, and excess, with a real quantity to ship to each warehouse. It's a formula you set to your own playbook — not a black box, and not a spreadsheet you rebuild every Monday.

    Start where you are

    From the report you already pull.

    No new exports, no data entry. Drop in your Amazon Inventory Ledger CSV, or connect SP-API once and Unilytic keeps it synced. Choose append mode to add a fresh snapshot or replace mode to rebuild from scratch — either way your full inventory history is reconstructed without manual reconciliation. A large ledger in, a clean send list out, the same day you upload.

    • CSV upload or SP-API — your choice, kept in sync.
    • Append or replace with full history rebuilt automatically.
    • No reconciliation — the ledger you have is all it needs.

    Your rules, written down

    A formula you control.

    Every seller's playbook is different, so the math is yours to set. Dial in a days-of-stock target, your low and excess thresholds, a round-up multiple to match carton sizes, a minimum send, and a sales-window cap so one freak week doesn't blow out the recommendation. Unilytic shows the arithmetic behind every number — and if you disagree, override any quantity by hand before it ships. It's a recommendation engine you can actually audit.

    • Days-of-stock target, low/excess thresholds, round-up multiple.
    • Minimum send and sales-window caps to smooth out noise.
    • The math is shown — and any quantity can be overridden by hand.

    From list to shipment

    The send list ships itself.

    A recommendation that ends in a spreadsheet is half a tool. Unilytic carries it through to a Seller-Central-ready shipment.

    Out / Low / Excess, sorted

    Every SKU lands in a bucket the moment you upload, so the urgent stockouts rise to the top and the overstocked SKUs stop getting reordered out of habit.

    Override before you ship

    Know something the data doesn't — a promo, a supplier delay, a launch? Change any quantity by hand and the totals update. The formula advises; you decide.

    Questions

    Replenishment, answered.

    How do I know how much inventory to send to Amazon FBA?01

    Upload your Inventory Ledger and Unilytic computes a quantity to send per SKU and per warehouse, using a formula you set — days-of-stock target, low and excess thresholds, round-up multiple, and minimum send. The arithmetic behind each number is shown, and you can override any quantity before shipping.

    Can I set my own reorder rules instead of a fixed formula?02

    Yes — the formula is fully tunable to your playbook. Adjust the days-of-stock target, thresholds, round-up multiple, minimum send, and a sales-window cap so a single unusual week doesn't distort the recommendation. Nothing is a black box.

    Does it tell me which warehouse to send each SKU to?03

    It does. Recommendations are per-warehouse, so each FBA location and your own warehouses get their own send quantity — no facility starves while another overflows. From there, recommendations turn into draft shipments in two clicks.

    What file do I need to upload to get started?04

    The Amazon Inventory Ledger CSV you already pull from Seller Central — or connect SP-API once and Unilytic keeps it synced. Append a new snapshot or replace the whole history; either way it rebuilds your inventory without manual reconciliation.
