Built for Amazon sellers

A 3PL for Amazon sellers stores your inventory, ships your Seller Central FBM orders straight to customers, and preps FBA shipments for inbound to Amazon's fulfillment centers. Simpl does all three from one Austin warehouse and one inventory pool, so your FBM orders and FBA prep run through a single team.

01
Who this is for

You sell on Amazon Seller Central and want a 3PL to pick, pack, and ship those orders — instead of, or alongside, FBA. FBM sellers who want tighter control over packaging, returns, and stockouts. Multi-channel brands running Shopify, TikTok Shop, and Amazon from one inventory pool. Sellers splitting between FBA for some SKUs and a 3PL for others. Brands moving off FBA because long-term storage fees, removal fees, or commingling rules stopped making sense.

02
What we ship for Amazon sellers

FBM order fulfillment. Multi-channel inventory — same SKUs ship to Shopify, TikTok Shop, BigCommerce, your own cart, and Amazon from one pool. Amazon order fulfillment with same-day pick, pack, and ship on orders that hit our cutoff. Returns processing: inspect, restock, or dispose per your rules. Light kitting, bundling, and pre-ship inserts. Custom branded packaging — mailers, dunnage, thank-you cards.

03
Direct Seller Central integration

We integrate with Seller Central, so an Amazon order routes straight into our warehouse and ships under your Amazon shipping SLA. No manual CSV upload, no Shopify-import hop in the middle. Carriers: USPS, UPS, FedEx, DHL. We hand orders directly to each carrier from Austin, no zone-skipping middle layer.

04
What's in the $7/order rate

Three picks, postage, and packaging in one number — that's our flat-rate pricing, starting at $7/order. No SKU-storage tier hidden under the headline, no per-touch pick fees, no separate insert charge. Same per-order rate whether you're doing 50 Amazon orders a month or 5,000+. Storage and oversized items are billed separately. The quote covers the math up front.

05
FBA prep is a separate service

Need help getting pallets ready for Amazon FBA inbound — labeling, polybagging, bundling, FNSKU? That's our Amazon FBA Prep service. Some brands run both at once: we prep pallets for FBA on the SKUs that work in FBA, and we fulfill 3PL-side on the SKUs that don't. Same warehouse, one quote.

06
Why Austin

Our warehouse is at 3714 Bluestein Drive, Suite 700, Austin, TX 78721. From Austin, 2-day ground reaches most of the contiguous US, which keeps your Amazon shipping SLA green without paying air rates. We ship to all 50 states and 200+ countries.

Frequently Asked Questions

FBM (Fulfilled by Merchant) means you or a 3PL ships each order directly to the buyer. FBA (Fulfilled by Amazon) means your stock goes to Amazon's warehouses and Amazon ships it. FBM gives you control over costs and packaging; FBA gets you the Prime badge. Most sellers run both: FBM through a 3PL for cost-sensitive SKUs, FBA for high-velocity Prime items.

A 3PL (third-party logistics provider) for Amazon sellers is a company that stores your inventory and handles picking, packing, and shipping on your behalf. For Amazon specifically, a 3PL can fulfill orders in a few ways: ship Merchant-Fulfilled (FBM) orders directly to your customers, prep inventory for Fulfillment by Amazon (FBA) so it meets Amazon's inbound requirements before it reaches a fulfillment center, and route the same inventory to other sales channels from one stock pool. Instead of running a warehouse yourself, you send inventory to the 3PL and they ship your Amazon orders same-day.

Yes, we maintain 99.99% order accuracy through barcode scanning, quality control checks, and process verification. In the rare case of an error, we cover all costs to correct it including return shipping and re-fulfillment - no questions asked.

Every client receives a dedicated account manager who learns your business, understands your requirements, and serves as your primary point of contact. No ticket systems, no rotating support staff - just one person who knows your business and is available Monday-Friday 9 AM to 5 PM CST.

These are three ways to fulfill Amazon orders.

FBA (Fulfillment by Amazon) — you send inventory to Amazon's fulfillment centers, and Amazon stores it and ships each order.

FBM (Fulfilled by Merchant) — you keep inventory yourself (or with a 3PL) and ship each order directly to the customer. You control packaging and carrier.

Seller-Fulfilled Prime (SFP) — a program where you fulfill orders from your own (or a 3PL's) warehouse but still show the Prime badge, which requires meeting Amazon's Prime delivery speed and reliability standards.

The trade-off is control versus convenience. FBA hands storage and shipping to Amazon. FBM and SFP keep fulfillment in your hands (or your 3PL's) while you still sell on Amazon.

Orders received by 12 PM CST ship the same day. Orders received after 12 PM ship the next business day. During peak seasons (Black Friday, holiday rushes), we maintain this standard through expanded staffing and extended hours - no slowdowns when you need us most.

Yes. Simpl preps FBA-bound inventory (FNSKU labeling, poly-bagging, bundle prep) and ships it to Amazon's fulfillment centers, and Simpl also fulfills FBM orders by shipping them directly to your customers from Austin, TX. Many brands use both: FBA prep for their Amazon-stored inventory and FBM for orders they'd rather fulfill themselves. Both run from the same warehouse and the same inventory system.

The entire platform is included at no extra cost - inventory management system, returns portal, automation tools, real-time order tracking, and detailed reporting. Everything you need to run efficient operations is built into our service with no hidden software fees.

Simpl's order fulfillment starts at $7/order — a flat rate that covers picking, packing, postage, and packaging in one number, with no separate pick fees or surcharge stack. There's a $750/month account minimum, billed pay-the-difference: if a month's order billing comes in under $750, you're charged only the gap, not a flat fee on top. Amazon FBA prep is billed separately as a flat fee per unit, since prep work is priced by the unit rather than the order.

No setup fees, no onboarding charges, and no receiving fees - period. While most 3PLs charge $500-2,000 in setup fees plus $0.25-0.50 per item for receiving, we believe these should be included in our service. You only pay for actual fulfillment and storage, with complete transparency from day one.

Yes. Simpl connects directly to Amazon Seller Central, so orders flow in without manual CSV uploads and inventory stays in sync in real time. Beyond Amazon, Simpl integrates natively with Shopify, Shopify Plus, BigCommerce, WooCommerce, and Squarespace, plus the Walmart, eBay, Etsy, and TikTok Shop marketplaces, and offers an open API for custom setups. Your Amazon stock shares one inventory pool with those channels, so selling across marketplaces doesn't mean splitting inventory.

The entire platform is included at no extra cost - inventory management system, returns portal, automation tools, real-time order tracking, and detailed reporting. Everything you need to run efficient operations is built into our service with no hidden software fees.

We provide free standard packaging including right-sized corrugate boxes and recycled mailers, plus kraft tape for sustainability. Our smart packaging system reduces waste and shipping costs. Need custom packaging? We can accommodate that as well and only charge standard storage fees for your custom materials - no markup or handling fees like most 3PLs.

No, we provide complimentary good-faith receiving for all inventory shipments. This includes inspection, scanning, and putaway into our warehouse management system at no charge. Unlike most 3PLs that charge $0.25-0.50 per item plus appointment fees, we believe receiving should be included as part of our service.

Our flat-rate fee includes picking, packing, standard packaging materials (boxes, mailers, padding), shipping costs, and order processing - all bundled into one simple price based on package weight. No setup fees, no onboarding charges, no receiving fees, no per-item picking charges, no packing fees, no surprise "handling" costs. You pay one flat rate per order, period. This typically saves 20-40% compared to 3PLs with complex itemized pricing plus separate shipping charges.

Amazon fulfillment services handle the storage, picking, packing, and shipping of orders sold on Amazon. You can use Amazon's own program, FBA, or a third-party 3PL that preps and ships your Amazon inventory. Simpl offers Amazon FBA prep and integrates with Amazon to fulfill your orders, with pricing that starts at $7/order.

We can have you up and running in 5-7 days, not weeks. Our streamlined onboarding adapts to your timeline - whether you need to move quickly or prefer a gradual transition. We handle inventory receiving, system integration, and testing to ensure everything works perfectly before going live.

If you're spending more than a few hours daily on fulfillment, or if packing orders is keeping you from growing your business, it's time to consider outsourcing. The right 3PL partner will save you time and often reduce shipping costs while improving delivery speeds for your customers.

Absolutely. We fulfill everything from individual retail orders to full pallet shipments, including EDI compliance, custom labeling, and freight shipping. Our flexible system handles both your direct-to-consumer and wholesale fulfillment needs under one roof with the same dedicated account manager.

Yes! From subscription boxes to promotional bundles, we handle all types of kitting and light assembly. Our team can build custom kits as orders come in or pre-assemble items for faster shipping. We also offer product bundling, promotional inserts, and gift wrapping services.

We make returns simple with our automated returns portal that lets customers generate return labels instantly. You choose to use our discounted shipping rates or your own carriers. We process returns within 1-2 business days and charge only a flat processing fee per return. Custom return rules and donation programs are available.

Every client receives dedicated account management and enterprise-level service regardless of size - that's why we have a $750 monthly minimum. This is typically reached with just ~100 orders per month, much lower than industry standards. If your monthly fees don't reach $750, you only pay the difference. This ensures growing brands get the same premium service as our largest clients.

Yes! We handle everything under one roof - Amazon FBA prep, direct-to-consumer fulfillment, kitting services, custom assembly, and specialized prep requirements. Our flexible approach means you can consolidate all fulfillment needs with one partner instead of managing multiple vendors.

The entire platform is included at no extra cost. This includes our inventory management system, returns portal, automation tools, and real-time order tracking - everything you need to run your operations efficiently.

Yes! Our new system can print custom gift messages unique to each order, giving you complete control over the unboxing experience. We also offer handwritten notes - just ask your account manager for details.

Yes - we provide worldwide shipping through established carrier networks. We'll work with you to find the most reliable and cost-effective international shipping solutions for your business.

Amazon FBA stores and ships your inventory through Amazon's own warehouses, while third-party fulfillment uses an independent 3PL to do the same across all your sales channels. FBA is built only for Amazon orders and comes with Amazon's storage fees and prep rules. A third-party provider like Simpl fulfills orders from your whole catalog, Amazon plus your own store and other marketplaces, under one flat rate starting at $7/order.

It makes sense when you sell on more than just Amazon, want to avoid Amazon's long-term storage fees, or need more control over branding and packaging. FBA works well for Amazon-only sellers, but it gets expensive for slow-moving inventory and limits how your shipments look. A third-party service like Simpl fulfills your Amazon, Shopify, and other channel orders from one inventory pool, with same-day shipping before 12pm CT.

They prep your inventory to Amazon's exact specifications before it ships to an Amazon fulfillment center, including FNSKU labeling, poly bagging, bundling, and packaging that meets Amazon's standards. This keeps your shipments from being rejected or hit with non-compliance fees at the FBA receiving dock. Simpl handles FBA prep so your inventory arrives at Amazon ready to sell.

Third-party Amazon fulfillment with Simpl starts at $7/order, with the pick, packaging, and postage included in that flat rate. FBA prep and storage are priced based on the work and the space involved, and storage is billed by the type of space your inventory uses. The per-order rate holds whether you ship 50 orders a month or 5,000.
