Guides by role

For sellers and suppliers

How to start selling, upload the catalogue, fulfil orders and get paid.

Seller guide

You sell on MONTFIX as the seller of record: MONTFIX collects the payment, issues invoices on your behalf and pays you out every week.

  1. Complete the company check (KYB)

    How it's done

    1. Settings › Store: check your company details, VAT id and bank account (IBAN).
    2. We cannot pay out without a verified account.

  2. Upload the catalogue and feed

    How it's done

    1. Data feeds: upload a file or give a URL (CSV, XLSX, XML).
    2. Map the columns, preview the first rows and run the import.
    3. Stock and prices then update automatically on schedule.

  3. Set prices and promotions

    How it's done

    1. Price lists: special prices for customer groups.
    2. Promotions: a discount on products or the cart, with start and end dates.

  4. Fulfil orders

    How it's done

    1. Orders: accept the order within the SLA.
    2. Print the label, pack and mark it “Shipped”.

  5. Returns and disputes

    How it's done

    1. Returns: approve or reject with a reason.
    2. Disputes: answer the buyer — MONTFIX steps in if you cannot agree.

  6. Get paid

    How it's done

    1. Payouts: every Monday — last week's sales minus commission.
    2. Download the CSV statement for your accounting.

MONTFIX supplier guide

You sell through MONTFIX as a commissionaire supplier: MONTFIX sells to the buyer, you ship and invoice MONTFIX.

  1. Check your details

    How it's done

    1. Settings › Store: company details, warehouse, cut-off time.
    2. Check the bank account we pay into.

  2. Connect the stock and price feed

    How it's done

    1. Data feeds: a file, a URL or SFTP.
    2. Accurate stock means fewer cancelled orders and a better supplier score.

  3. Accept orders on time

    How it's done

    1. Orders: accept a new order within the SLA (usually 2 h).
    2. If you don't have the goods, decline with a reason — we route the order to someone else.

  4. Ship and mark it

    How it's done

    1. Print the label or enter the tracking number.
    2. Mark it “Shipped” — the buyer gets a tracking link.

  5. Invoice MONTFIX

    How it's done

    1. Payouts › Your invoices to MONTFIX: upload an invoice for every order.
    2. Matching amounts are reconciled automatically.

  6. Answer price requests

    How it's done

    1. Price requests: buyers ask for a price for larger quantities or unpriced items.
    2. Answer with a price and lead time — the buyer sees it at once.
