If you sell subscription boxes or run a crowdfunding launch, both of these names will come up. ShipMonk is a large, tech-forward 3PL known for subscription and omnichannel fulfillment at scale. Simpl Fulfillment is a flat-rate, Austin-based partner built for growing DTC brands, including the same subscription and crowdfunding verticals, without the enterprise overhead.
They overlap on what they do. They differ on who they're built for. ShipMonk is designed for brands shipping high volume through complex kitting and proprietary software. Simpl is designed for brands that want fulfillment that works without a volume minimum to clear or a rate card to decode. This page compares the two on pricing, specialties, and support so you can match the 3PL to your stage.
Simpl is a D2C-focused 3PL in Austin, Texas. Pricing starts at $7/order, with the pick, postage, and packaging already in that rate. Same-day shipping is standard on orders received before 12pm CT, and there's no onboarding fee, so most brands are live in 5 to 7 days.
Simpl runs the subscription-box and crowdfunding verticals that overlap with ShipMonk's core, plus kitting and assembly, B2B, Amazon FBA prep, and returns. Every client gets a dedicated, named account manager reachable by email with same-day responses. Order accuracy runs 99.99%, with mistakes corrected at Simpl's cost.
The model fits brands doing 50 to 5,000+ orders a month who want transparent pricing and a real contact, not a tiered support structure or a monthly volume threshold.
ShipMonk is a larger 3PL with 9 fulfillment centers across the US, Canada, the Czech Republic, and the UK. Its calling card is proprietary warehouse software and deep subscription-box capability, built for brands scaling into high-volume, omnichannel selling.
ShipMonk's pricing is quote-based. Fee components are disclosed (storage, pick-and-pack, receiving, returns, shipping through its Virtual Carrier Network), but there's no published per-order rate. It applies a monthly minimum tied to your order volume, and subscription batches under 50 orders can incur a batching fee. Account management is handled by a dedicated team alongside its support reps.
ShipMonk fits brands with enough volume to clear the minimum, complex kitting needs, or omnichannel operations that benefit from advanced in-house technology.
ShipMonk discloses its fee components but not its rates. You get a custom quote, and it carries a monthly minimum tied to your order volume. That structure works well once you're shipping enough to clear the floor and want itemized control over each cost line. For a brand that's still growing into its volume, it can mean paying toward a minimum before the model pays off.
Simpl publishes its starting rate: $7/order, with the pick, postage, and packaging bundled in. The account minimum is $750/month, billed pay-the-difference, so if your orders bill under $750 in a month, you're charged only the gap rather than a flat fee on top. You can forecast your fulfillment cost before any sales call.
If you're optimizing a high-volume operation with complex per-line costs, ShipMonk's itemized quote gives you levers. If you want a number you can plan around today, Simpl's flat rate is simpler. See the pricing page for the full breakdown.
This is where the two overlap most, so it's worth being specific.
ShipMonk built much of its reputation on subscription-box fulfillment and handles it at scale with advanced kitting. The tradeoff is the model around it: quote-based pricing, a volume minimum, and a batching fee on subscription runs under 50 orders.
Simpl runs subscription-box fulfillment too, through the same flat-rate model, with pick, postage, and packaging in one number, kitting and assembly available, and a named account manager on your account. For a subscription brand in the 50 to 5,000 orders/month range, that means predictable per-box economics without clearing an enterprise threshold first.
The question is scale. If you're running enterprise-volume subscription batches with intricate kitting, ShipMonk's depth fits. If you want subscription fulfillment that's simple to price and easy to reach, Simpl fits.
Simpl ships fragile and high-value goods with a near-zero breakage rate and insured shipping available. Storage is ambient, and orders move through UPS, USPS, and FedEx with the carrier included in the flat rate and a tracking number on every shipment. For brands shipping glass, candles, or other breakables, careful handling is a real part of the value, not an upsell.
Every Simpl client gets a dedicated account manager: a named person who knows the account, reachable by email, answering same-day during business hours. ShipMonk provides dedicated account management alongside its support reps. Both are a step up from a pure ticket queue. The difference is that with Simpl, the named-contact model is the standard for every client regardless of size.
Changing 3PLs is the kind of project brands put off, usually because the migration feels riskier than staying put. With Simpl, two things lower that risk. There's no onboarding fee, so the move doesn't carry a setup charge, and onboarding runs 5 to 7 days with a named account manager coordinating the inbound shipment, the integration, and the first orders out.
The sequence is simple: connect your store, send inventory to Austin, confirm kitting rules and packaging, and start shipping. Receiving runs 1 to 3 days once stock arrives. For a subscription brand mid-cycle, the named AM also helps time the cutover so a renewal batch doesn't fall in the gap.
Choose Simpl Fulfillment if you're a growing DTC, subscription, or crowdfunding brand that wants flat-rate pricing you can model, a named account manager for every client, and subscription fulfillment without a volume minimum or batching fee to navigate.
Choose ShipMonk if you're scaling into enterprise volume, need advanced proprietary software for complex omnichannel operations, and want itemized cost control across each fulfillment line.
Both handle subscription boxes, crowdfunding, and kitting well. The real split is stage and complexity: flat-rate simplicity with a real contact, or enterprise-grade tech with itemized scale.

Both handle subscription boxes well. It's one of ShipMonk's flagship verticals and a core Simpl service. The difference is the model. ShipMonk prices through custom quotes with a volume minimum and a batching fee on runs under 50 orders. Simpl uses flat-rate pricing starting at $7/order, with kitting and assembly available and a named account manager for every client. For brands in the 50 to 5,000 orders/month range, Simpl's predictable per-box economics are easier to plan; for enterprise-volume subscription operations, ShipMonk's scale and tech depth fit.
ShipMonk applies a monthly minimum tied to your order volume, and subscription batches under 50 orders can incur a batching fee. Exact figures come through a custom quote. Simpl, by comparison, uses a $750/month account minimum billed pay-the-difference, so you're charged only the gap if a month bills under $750.
Simpl publishes a starting rate of $7/order that includes pick, postage, and packaging. ShipMonk discloses its fee components (storage, pick-and-pack, receiving, shipping) but not its per-order rate — pricing comes through a custom quote with a monthly minimum. If you want a number to model before a sales call, Simpl's flat-rate is easier to forecast.
Yes. Simpl offers kitting and assembly as part of its standard services, covering subscription box assembly, multi-item bundles, and custom packaging. Kitting work is priced separately from the $7/order fulfillment rate — ask for a quote based on your specific kitting requirements.
Both Simpl and ShipMonk handle crowdfunding fulfillment. Simpl's flat-rate model is particularly well-suited to the burst-volume nature of crowdfunding campaigns: no monthly minimum to clear before the campaign ships, a named account manager who knows your timeline, and same-day shipping on orders received before 12pm CT. See Simpl's crowdfunding fulfillment page for specifics.
ShipMonk is geared toward mid-to-large volume brands. Its monthly minimum and quote-based pricing structure work better for brands that have enough volume to clear the floor. For small businesses or brands still growing into their volume, Simpl Fulfillment's pay-the-difference minimum and flat-rate pricing are a more predictable fit.
