DreamPro Junior — Fulfillment Partner Quote Requests

Three ready-to-send quote-request emails calibrated to each partner's typical onboarding flow. Per-box fulfillment is the single highest-leverage unknown in the unit-economics model — a $4/box swing moves the per-starter contribution by ~$13 and break-even by ~30 subscribers. Get all three quotes in before locking the BOM or quoting sponsors a final number.

Same shipping spec for all three (so you can compare apples-to-apples). Same expected-volume framing. Differences are in tone, contracting model, and what additional services each can offer.

Status: drafts. Send all three the same day so quotes arrive in roughly the same window.

The shared spec to send to all three

This block goes in every email so quotes are directly comparable. Copy it verbatim.

SHIPMENT SPECIFICATION

Box dimensions: ~9" × 6" × 2" (small mailer, fits through a USPS regional rate slot)
Weight per box (boxes 1-4): 6-12 oz depending on box (Box 1 heaviest, Box 4 lightest)
Tools Kit (one-time, ships with Box 1): ~12" × 9" × 3", 1.2 lb (contains a NanoVNA pocket analyzer + breadboard + clips + jumper wires)

VOLUME PROJECTIONS (Year 1)

  Pilot quarter:     100-250 subscribers, 4 box shipments per subscriber per year
  Steady-state:      target 500 subscribers within 12 months
  Peak month volume: ~250 boxes/month at 250 subscribers (one-quarter cycle)
  Tools Kits:        one per new subscriber (so 100-500 in Year 1, then a smaller renewal flow)

DESTINATION MIX

  Year 1: 90% US (lower-48), 10% international (CA, UK, AU, EU mix)

WHAT WE NEED FROM YOU

  1. Per-box pick-pack cost at the listed volumes
  2. Per-Tools-Kit pick-pack cost (different SKU, different size)
  3. Per-shipment shipping cost: USPS Ground Advantage for US, cheapest reasonable
     option for international (we're flexible)
  4. Monthly storage cost (estimated 2-4 pallets at peak)
  5. Inbound receiving cost (parts arrive from suppliers in batch)
  6. Returns / replacement handling cost (we expect <2% return rate)
  7. Stripe / subscription-billing integration: do you push fulfillment off our
     subscription webhook, or do we batch-send orders to your portal?
  8. Onboarding lead time (we want to ship Box 1 within ~12 weeks of contract sign)

OUR ROUGH BUDGET TARGET

  ~$5 per-box pick-pack + ~$5 shipping (US) = ~$10 per US shipment all-in.
  We'd love to hit that, would consider $12 if it includes assembly or value-add.

1 — Cratejoy

Why this framing: Cratejoy is purpose-built for subscription-box businesses. They do the marketplace + the fulfillment + the billing in one stack. Lead with the fact that we want to keep our own checkout (Stripe + the existing HiveJournal app) but want their fulfillment ops, since they're the operator most likely to push back on that boundary.

To: partnerships@cratejoy.com (or via the Cratejoy Make site quote form) Subject: Quote request — quarterly STEM kit, 100-500 subscribers Year 1

Hi Cratejoy team,

I'm scoping fulfillment for a quarterly STEM subscription box launching in late 2026. We're an existing software platform (HiveJournal — citizen-science platform with a live participant base in 30+ countries) extending into a physical kit subscription called DreamPro Junior. Four boxes a year for ages 8-14, focused on hands-on RF / electronics experiments tied to a published research catalog.

A few notes upfront on what we are and aren't looking for:

  • We're keeping our own checkout and subscription billing (Stripe + our existing user accounts), so we'd be asking for Cratejoy Make-style fulfillment-only — not the full marketplace stack. If that's not how Cratejoy is set up to onboard partners these days, please point us at the right contact.
  • We'd want to use the Cratejoy fulfillment integration with our subscription webhook — every successful Stripe quarterly charge fires a fulfillment order. Comfortable with batch CSV upload as a fallback.
  • We're price-sensitive but not at the expense of professionalism — kit unboxing matters more for our growth model than for typical subscription boxes because we're trying to get K-12 households doing real lab work, so the package needs to feel like an instrument-grade kit, not a toy.

[INSERT THE SHIPMENT SPECIFICATION BLOCK ABOVE]

A few extra questions specifically for Cratejoy:

  1. Can you handle a two-SKU first shipment — Box 1 + the optional Tools Kit shipped together as one parcel when the subscriber selects both at checkout?
  2. Do you have an existing rate card for STEM-education subscription boxes specifically? KiwiCo and Mel Science use Cratejoy or Cratejoy-equivalent operators; we're aiming at the same volume profile.
  3. Customs handling for international shipments — do you handle the duties-paid landed-cost calculation for CA/UK/AU/EU, or is that on us?
  4. Is there a minimum monthly volume commitment to keep our pricing tier? (We're starting at ~25-60 boxes/month and ramping.)

Happy to share the box specs, the unit-economics model, and the platform context. Both are public docs:

We'd ideally love a quote within ~3 weeks so it can feed our BOM-lock decision. Let me know what you need from us to get there.

2 — ShipBob

Why this framing: ShipBob is the generalist 3PL — DTC e-commerce, multiple warehouses, strong tech integration. They're the safest "professional fulfillment partner" choice but probably won't have subscription-box-specific tooling. Lead with the fact that we want their network's geographic distribution (multiple US warehouses → faster + cheaper US shipping) and their proven Stripe integration.

To: sales@shipbob.com (their sales team owns the inbound quote process) Subject: 3PL quote request — recurring subscription box, 4 shipments/subscriber/year

Hi ShipBob team,

We're scoping fulfillment for a quarterly STEM subscription box launching late 2026. Existing software platform (HiveJournal — hivejournal.com) extending into a physical kit. 100-250 subscribers projected for the pilot quarter, target 500 within 12 months. Four shipments per subscriber per year, plus an optional one-time "Tools Kit" attached to the first shipment.

Specifically interested in ShipBob because of:

  1. Multi-warehouse network — split inventory across at least one east-coast + one west-coast warehouse so we can reduce average US shipping distance + cost. (Roughly 60% of our existing user base is east of the Mississippi.)
  2. Native Stripe integration — every successful subscription charge would fire a fulfillment order; we want that flow to be webhook-driven, not manual.
  3. Established DTC kit shipping volume — we don't want to be your first STEM-kit customer, and we're confident you have similar SKUs in your existing book.

[INSERT THE SHIPMENT SPECIFICATION BLOCK ABOVE]

Two ShipBob-specific questions on top of the standard request:

  1. Inventory-split recommendation — given our 60/40 east/west US user distribution and ~250 boxes/month at steady state, what's your recommended split across warehouses? Single fulfillment center, or 2-warehouse split?
  2. Returns address handling — we want returns routed to a single warehouse (not back to wherever it shipped from) so we can do quality-control on the rare returns in one place. Is that a standard option?

Two reference docs you can read at your pace if helpful:

We're aiming to lock the fulfillment partner decision within ~4 weeks. A quote within ~3 weeks would let us compare you against two other vendors and make a clean call.

3 — Maker-space partner (template)

Why this framing: A maker-space partner (likely Boulder, CO — already on the maker-space outreach list per the existing P1 marketing tasks; alternatives: Berlin, Melbourne, Brooklyn) won't compete on per-box fulfillment cost vs. ShipBob/Cratejoy. The pitch is what they offer that the 3PLs don't: assembly-as-community-event, an authentic brand story, and an in-network audience of exactly the K-12 parents we want to reach. The pitch is more of a partnership conversation than a quote request.

Address to: the maker-space's executive director by name. Look up first. The template uses [NAME] and [MAKER SPACE NAME] — fill in before sending.

To: [director-email]@[makerspace].org Subject: Partnership inquiry — could your community assemble a STEM kit for us?

Hi [NAME],

I'm writing with an unusual partnership idea that I think could be a small but meaningful revenue stream for [MAKER SPACE NAME] and a genuine community story for what we're building. Probably better discussed over a 20-minute call than over email, but here's the shape of it.

I run HiveJournal, a citizen-science platform built around a published analysis of 768 open-energy device patents. We're launching a quarterly STEM kit subscription called DreamPro Junior — four kid-safe boxes a year for ages 8-14, focused on hands-on RF and electronics. Each box maps to one of the design patterns in the patent catalog.

The boxes ship as parts. Someone has to assemble each kit (sort the parts into compartments, pack the box, attach the instruction card, label the mailer). Two ways to do that:

  1. Hire a 3PL (ShipBob, Cratejoy) — clean, scalable, ~$5 per box fully loaded.
  2. Partner with a maker space — your members assemble the kits as a paid community event, you take a margin, kits ship from your warehouse, and we get to tell the story that "your kid's experiment kit was packed by adult makers in [CITY]."

The second option is structurally worse on cost-per-box but structurally better on every other dimension we care about — community story, brand authenticity, geographic anchoring, and an in-network audience of exactly the parents most likely to buy the subscription.

What we'd want from [MAKER SPACE NAME]:

  • Pilot-quarter assembly + storage + shipping for ~100-250 boxes per quarter (so 400-1,000 box shipments over Year 1) plus an optional Tools Kit shipping with each first-time subscription.
  • A monthly "kit packing party" — a recurring 2-3 hour event where members assemble a batch of kits together. We'd cover materials + your hourly facility-use rate; you'd keep any member fees from the event.
  • Use of your shipping address as our return address so QC routes to one place.
  • One photo per packing event we can post — anonymised, no faces unless people want to be in them.

What [MAKER SPACE NAME] would get:

  • Per-kit margin at whatever rate you bill assembly-and-handling. We're budgeting up to $12 per box all-in (parts already included), of which maybe $7-9 would be your line. Real numbers depend on your hourly rates.
  • A dedicated "Assembled in [CITY] at [MAKER SPACE NAME]" sticker on every kit shipped from your warehouse plus prominent acknowledgement on our kit landing page (currently at hivejournal.com/dreampro/kits).
  • A real revenue stream tied to a recurring program — quarterly cadence means quarterly billable activity, not a one-off project.
  • A funnel into your member base — the K-12 families who subscribe to the kits are a near-perfect demographic for your existing programs. We'd happily cross-promote your camps + workshops to subscribers in your geographic radius.
  • First right of refusal on a Year-2 program expansion if Year 1 works.

If this sounds at all interesting, I'd love a 20-minute call to walk you through the box specs and the volume math. Both are public:

Honest question for you: is this the kind of thing [MAKER SPACE NAME] would want to take on, or is it a poor fit for your current ops? Either answer is genuinely useful — if it's not a fit, I'd appreciate any pointers to maker spaces in nearby cities that might be a better match.

Thanks for reading,

Sandon Jurowski Founder, HiveJournal sandonjurowski@gmail.com

Send-order recommendation

Send all three the same day, but the call cadence should run in this order:

OrderPartnerWhy
1st (highest priority response)ShipBobTheir inbound sales process is fastest (~3-5 business days for a quote at this volume tier). Their number is the apples-to-apples baseline for the unit-economics model.
2ndCratejoySlower process (~1-2 weeks), but they understand subscription-box ops natively, so their quote will surface gotchas the generalist 3PL won't.
3rd (longest cycle)Maker spaceWon't be a quote in the formal sense — will be a 20-minute call followed by a follow-up "here's what we could do" email. Plan for ~3 weeks. Worth pursuing in parallel because the quality is so different from a 3PL.

Decision rule: if ShipBob comes in at < $9/box all-in for a US shipment, default to them; reserve the maker-space partnership for the marketing/story angle (could still ship a small percentage of kits out of [MAKER SPACE NAME] for the brand story while bulk goes through ShipBob). If ShipBob comes in at > $11/box, push hard on the maker-space option as the cost-competitive alternative even at slower scale.

Pre-send checklist

  1. Maker-space target. Currently a [MAKER SPACE NAME] template — pick the actual maker space first. Boulder (BLDR Makers, Maker Faire Boulder), Brooklyn (NYC Resistor), Berlin (Fab Lab Berlin), Melbourne (Connected Community HackerSpace) are the existing P1 outreach targets. Boulder is geographically closest to the existing Open Energy core community and is the recommended pilot.
  2. Replace placeholder doc URLs with the live render paths once published, or send as Google Doc links.
  3. Confirm the inventory-split assumption in the ShipBob email (60% east of Mississippi). Currently a guess; pull from the world map's actual user distribution if you want a real number.
  4. Confirm the budget target ($10/box all-in US). Based on the unit-economics model's $5 + $5 estimate. If the model has been re-run with new fixed-cost numbers, update the budget here too.
  5. Add yourself to a "follow up in 7 days" reminder for each — quote requests at this volume tier get deprioritised by 3PL inbound queues unless you nudge.
