Frequently Asked Questions
Subscription box fulfillment is the pick, pack, and ship process for recurring box orders. A 3PL stores your products, assembles each box, and ships it to your subscribers on schedule. Simpl runs this as a flat-rate service starting at $7/order, which includes picking, postage, and packaging.
You send inventory to the warehouse. When a subscription order comes in, the team picks the items, builds the box, and ships it. Kitting and assembly is a standard Simpl service, so pre-built boxes and custom inserts are handled in-house. Orders received before 12pm CST ship the same day, at 99.99% order accuracy, with any errors corrected at Simpl's cost.
Simpl's subscription box fulfillment starts at $7/order, flat-rate. That covers picking, postage, and packaging, with no hidden fees. Kitting and assembly for building each box is a listed Simpl service. Storage is billed by warehouse storage type (bin, shelf, or pallet) based on the space your inventory uses.
Yes. Kitting and assembly is a standard Simpl service. The team combines products, inserts, and custom packaging into a finished box before it ships. You send components in bulk and the 3PL assembles boxes on demand, so you skip pre-building and storing them yourself.
Moving subscription box fulfillment to a 3PL lets you grow subscriber count without adding warehouse space or hiring packers each cycle. The 3PL absorbs the monthly assembly and shipping spike, manages address changes and cancellations, and keeps per-box costs predictable as volume rises. Simpl Fulfillment serves brands from 50 to 5,000+ orders a month, so a box can scale on the same account instead of switching providers as it grows.
Look for reliable kitting and assembly, on-time batch shipping, accurate inventory tracking across components, and clear pricing. Subscription boxes live or die on shipping consistency, since a late or wrong box drives cancellations. Simpl offers kitting and assembly, ships same-day before 12pm CT, hits 99.99% order accuracy with errors corrected at our cost, and gives every client a dedicated account manager.
Simpl onboards new brands in 5 to 7 days. That covers connecting your store, receiving your inventory (1 to 3 days once it arrives), and setting your kitting and shipping rules. After onboarding, orders received before 12pm CST ship the same day.
They receive your individual components, store them, and assemble them into finished boxes before each shipping cycle, following your packing layout and any inserts. This lets you buy components in bulk and have them combined into boxes only when it is time to ship. Simpl does the kitting and assembly, building each box to your specifications.
You scale by handing the warehousing, kitting, and shipping to a partner so growth does not outrun your own space and labor. The partner absorbs the rising box count, manages component inventory, and keeps per-box costs predictable as you add subscribers. Simpl charges the same flat rate starting at $7/order whether you ship 50 boxes a month or 5,000, so your fulfillment cost scales with you.
