Selling on Amazon FBA doesn't mean Amazon does everything. Your units still have to be received, prepped to Amazon's inbound requirements, and sent to the fulfillment centers — and when you go out of stock at Amazon or want to sell off your own store, you need a partner who can ship directly too. This list ranks the fulfillment partners that FBA sellers rely on in 2026.
We scored each on FBA prep capability, Amazon integration, direct-ship (FBM) backup, and per-order economics. Notes on how we evaluate are at the bottom.
Simpl offers Amazon FBA Prep as a core service: your inventory gets received, prepped to Amazon's inbound requirements, and sent on to Amazon — so you're not doing carton work in a garage or paying Amazon's own prep rates.
The reason to keep Simpl in the loop even if you're mostly FBA: it's also a full D2C 3PL. When a listing goes out of stock at Amazon, or you want to sell direct off Shopify, Simpl ships those orders too — at $7/order flat, covering three picks, postage, and packaging. That makes it one partner for both sides of an Amazon business instead of two.
Inbound inventory is received in 1–3 days once it hits the dock, so your units move into prep quickly rather than sitting. There's a $750/month account minimum billed pay-the-difference — charged only if a month runs under it. Direct orders received before 12pm CT ship the same day, on UPS, USPS, or FedEx with real-time tracking and carrier cost inside the flat rate. Accuracy runs 99.99%, corrected at Simpl's cost when something ships wrong.
Every client gets a dedicated account manager reachable by email with same-day responses. Simpl connects to Amazon, Walmart, eBay, Etsy, and TikTok Shop, plus Shopify, Shopify Plus, BigCommerce, WooCommerce, and Squarespace.

ShipBob's warehouse network suits larger brands running Amazon alongside a sizeable D2C channel, with inventory split across regions for shorter shipping zones. It leans enterprise on configuration and pricing, ships across UPS, USPS, FedEx, DHL, and Veho (crowdsourced last-mile, 60+ markets). FBA prep is available as a service.
Pricing is not published on ShipBob's website — rates are customized for each customer and require a quote. Same-day fulfillment is available at most locations, with cutoffs between noon and 6PM local warehouse time.
ShipMonk targets sellers with large catalogs across Amazon and other channels. Its Virtual Carrier Network selects carriers per shipment by algorithm, which can help rate optimization at high volume. FBA prep is available as a service, covering labeling, packaging, quality checks, and compliance.
Pricing is not published on ShipMonk's website — rates are volume-based and require a quote. A monthly minimum applies, calculated as a percentage of projected order volume and pick fees, with the exact amount set during the sales process.
Fulfillment for FBA sellers is scored on what actually matters when you're splitting volume between Amazon and your own store:

Yes. Simpl offers Amazon FBA Prep — receiving your inventory, prepping it to Amazon's inbound requirements, and sending it to Amazon. Confirm current prep scope with any provider before committing.
For the times FBA can't cover you: out-of-stock at Amazon, selling direct off your own store, or wanting one partner for both. Simpl handles FBA prep and direct D2C/FBM shipping, so you're not running two vendors.
With Simpl, inbound inventory is received in 1–3 days once it reaches the dock, so units move into prep quickly. Ask any provider about receiving turnaround before you commit.
Simpl ships direct orders at $7/order flat — three picks, postage, and packaging included. Orders received before 12pm CT ship the same day.
