Simpl Fulfillment invoice audit

Simpl Fulfillment prices fulfillment as one flat fee per order, which leaves fewer lines on the invoice and makes each one matter more. Below is what the published pricing says and what to check on every Simpl invoice. Your own quote wins over the public page, so check against the quote you signed if it differs.

What Simpl's pricing page says

From the Simpl Fulfillment pricing page, as published when we checked in November 2026:

• One fee per order, by weight, starting at $7 per order. It covers up to three picks, pick and pack, packaging and postage.
• A $750 monthly minimum, billed pay-the-difference. If a month's order billing comes to less than $750, only the shortfall is added. If it is more, the minimum does not apply. Merch drops are exempt.
• No setup, onboarding, receiving or per-SKU fees. Receiving is free unless an inbound shipment breaks the receiving requirements; the extra labor is then billed at $45 per person-hour.
• Billed separately: storage by the space you use (small bin, large bin, shelf or pallet), returns per your rate card, and carrier surcharges such as fuel, residential or address correction when they apply.

What to check on every Simpl invoice

1. Each order's fee matches its weight. Take a sample of orders from your order export, look up their weights, and check each against the weight brackets in your quote.
2. The minimum is only the gap. Add up the month's order billing. If it is $420, the top-up should be $330, not $750. If it is over $750, there should be no minimum line at all.
3. Fees that should not be there. Setup, onboarding, receiving and per-SKU charges should not appear. A receiving labor charge needs the shipment it relates to and the hours.
4. Postage is already in the order fee. A separate postage or shipping line needs a reason; carrier surcharges are the exception the page names.
5. Storage matches the space you use. Compare the bin, shelf and pallet counts with what you have in stock, and the rates with your quote.
