Test it before you build it
$2,100 · 4 weeks · 20 prospects
For $2,100 and 4 weeks, prove mid-size 3PLs will pay for a white-label duty engine: $250 reports sold now and $1,500 deposits on launch integrations.
Riskiest assumption · A mid-size 3PL will pay a per-entry fee for an embedded classification and landed-cost engine instead of keeping the free carrier portals and outside brokers its importer clients already use.
1Focus group: who and where
The VP of operations or head of product at a US 3PL with 50-500 e-commerce clients, heavy in apparel and consumer goods importers under $20M revenue, whose clients have been calling about surprise duty bills since the 2025-2026 tariff rounds and who currently punts them to outside brokers.
where to find 20 · The IWLA (International Warehouse Logistics Association) member directory to build the target list; the r/freightforwarding and r/supplychain subreddits where 3PL and importer ops people trade tariff complaints daily; the PARCEL Forum trade show this September; the Shopify App Store fulfillment-service listings to find 3PLs that already ship software connectors and can absorb one more.
2Sell first, build later
Your clients' duty exposure, classified and priced: a 20-SKU HS classification and landed-cost report for one importer client, delivered in 5 business days, plus first claim on a white-label duty engine integrated into your WMS with your brand on it.
the ask · $250 per report now; $8 per filed entry once live; $1,500 refundable deposit for a launch integration slot.
a real yes · A real yes is a paid $250 report or a $1,500 deposit against a signed one-page SOW with a kickoff date. 'Our clients would love this', free pilot requests, and intros to their current broker are noes.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Fifteen 3PL customs pain calls
$0 · 7 days
Pull 40 names from the IWLA directory and the Shopify App Store fulfillment listings, email and DM until 15 calls are booked. Ask: how do your importer clients handle entries today, what does their broker charge per entry, and have clients asked you for duty help since the tariff changes. Founder runs every call.
keep going if · 8 of 15 say clients asked them for duty help in the last 60 days and can name the broker fee per entry their clients pay
2. Design-partner integration deposit
$100 · 14 days
On the same calls, pitch the design-partner slot: we build the connector for your WMS first and lock $8 per entry for 12 months, reserved by a $1,500 refundable deposit against a one-page SOW. Set up the invoice template and checkout before the first call so a yes can pay the same day.
keep going if · 2 of 15 3PLs pay the $1,500 deposit
3. Paid landed-cost reports
$600 · 10 days
Sell each 3PL a manual 20-SKU HS classification and landed-cost report for one of their importer clients: $250, delivered in 5 business days. Founders produce it with a licensed customs broker reviewing every classification at an hourly rate, which also builds the first accuracy corpus by hand.
keep going if · 4 of 15 3PLs buy a report and put the founders in front of the client it was for
4. PARCEL Forum floor test
$1,400 · 3 days
One founder attends PARCEL Forum with the report as the product: book 10 conversations with 3PL and forwarder ops leads on the floor and pitch the $250 report and the design-partner slot face to face. Log every objection about free carrier duty tools verbatim, since that is the card's stated kill risk.
keep going if · 5 of 10 floor conversations convert to a scheduled follow-up call with a named importer client attached
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$1,500
per prospect, refundable
how · A $1,500 refundable design-partner deposit, invoiced against a one-page SOW signed by the 3PL's VP of operations. Chosen because a 3PL will not sign a revenue share before seeing accuracy, but $1,500 against roughly $50,000-150,000 of first-year per-entry fees is a 1-3% earnest check they can approve without a committee. set up: Stripe Invoicing ↗
what it reserves · One of 3 launch integrations: their WMS connector built first, per-entry pricing locked at $8 for 12 months, and the duty engine carrying their brand.
refund · Refundable in full any time before integration kickoff, and refunded automatically if their connector is not live within 90 days of signing.
target · 2 deposits and 4 paid reports from 20 3PLs within 28 days
before taking money · Filing customs entries requires a CBP-licensed customs broker under 19 CFR part 111, so until DutyRail employs or partners with one, sell classification and landed-cost analysis only and route every actual filing through a licensed broker.
Go: build it if
2 design-partner deposits ($3,000) plus 4 paid reports ($1,000) from 20 3PLs, and 8 of 15 calls naming a client broker fee of $75 or more per entry: build the API.
Kill: stop if
0 deposits and fewer than 2 paid reports from 20 3PLs, or fewer than 3 of 15 calls naming any paid broker fee because carriers and forwarders already bundle duty calculation free: stop.

outreach message
You run fulfillment for apparel and consumer-goods importers, and since the 2025 tariff rounds your clients have been calling you about surprise duty bills you can't answer. I'm building the duty engine 3PLs white-label: HS classification, landed cost, and entries filed through a licensed broker at $8 per entry. Before the API exists I'm selling the manual version: a 20-SKU classification and landed-cost report for one of your clients, $250, delivered in 5 business days. Worth a 20-minute call this week?

The idea in full
- What
- DutyRail is an API that takes a purchase order or a product feed and returns an HS classification, duty and tariff-schedule exposure, a landed cost, and a filed customs entry through its own licensed broker desk. It ships as no-code connectors into Shopify-style storefronts, NetSuite-style ERPs and 3PL warehouse systems, so a 20-person importer never touches a customs form. DutyRail sells through freight forwarders, 3PLs and ERP resellers who rebrand it as their own duty engine, and takes a per-entry fee plus a share of the software subscription.
- Why now
- Five of the most recent YC batches in this cluster are tariff and import plumbing at once: Tarifflo Inc. (S26) on supply chain compliance and cost savings, Donkey (S26) on China factory-direct for US importers, Waybill (S26) on managed procurement, Saudara AI (X26) on overseas sourcing, and ShipTag (500G MENA 10) on cross-border duties and taxes, yet the radar records no pitch phrase repeating across 4 or more recent companies, so nobody owns the words or the API layer yet. Only 52 of the 1504 tracked companies in this cluster are from the last two years, and the SBA State Trade Expansion Program 2026 closing 2026-08-18 is still funding small exporters into the same rulebook.
- Wedge: first customer and entry point
- Start with one mid-size US 3PL serving apparel and consumer-goods importers under $20M revenue: give them a free classification endpoint for their onboarding flow, then charge per entry once their clients file through DutyRail.
- Path to 100x
- US customs brokerage and duty-management software is a $1-10B pool of per-entry fees and compliance subscriptions, and the winner is whoever holds the largest corpus of filed entries mapped to what CBP actually accepted, challenged or reclassified. Each partner-filed entry improves classification accuracy for every other importer, which lets DutyRail underwrite duty exposure, which is what makes ERPs and 3PLs build on it instead of a rules table, and that compounding accuracy is why this is winner-takes-most rather than a fee-per-form business.
- Ceiling
- If per-entry fees compress toward zero while the licensed broker desk keeps needing headcount, this caps as a $200-400M brokerage with an API skin.
- Closest real companies, as the generator saw them
- Tarifflo Inc. sells compliance and savings as a direct product to importers; ShipTag runs cross-border operations end-to-end as a service. DutyRail is deliberately not the customer-facing brand: it is the entry-filing and landed-cost API those operators and their ERP resellers embed, so distribution comes from partners rather than direct sales.
- Main risk
- Carriers and the large forwarders bundle duty calculation into their own portals for free and the API never gets a per-entry price.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
4/5
Revenue within a year via 3PL and ERP resellers, with a corpus of CBP-accepted entries that compounds classification accuracy no rules table matches.
Bootstrapper
5/5
Revenue within a year on per-entry fees, sold through 3PL and ERP partners to importers already paying brokers for the same filing.
Operator
5/5
Importers already pay per-entry broker fees, 3PLs and ERPs own the relationship, and revenue lands within a year.
Technologist
3/5
HS classification is LLM-easy, but the corpus of what CBP actually accepted or reclassified is a real accuracy asset that grows per entry.
Risk
5/5
Its own licensed customs broker desk gives clear regulatory footing, revenue inside a year, and distribution spread across many 3PLs, forwarders and ERP resellers.
trends
4/5
The 2025-2026 tariff upheaval is a dated shift, five tariff-plumbing companies in the latest YC batches confirm timing, and the embedded API layer is still unclaimed.
