Dutyback
Recovers duties and tax when cross-border agent orders come back
Dutyback is an agent service that handles the return leg of cross-border purchases made by AI agents: it files duty drawback and import VAT reclaims, computes the correct refund net of unrecoverable charges, and feeds the adjustment back to the merchant's books.

$600 · 4 weeks · 25 prospects
For $600 and 4 weeks, this proves whether the duty and VAT recoverable on a mid-size merchant's cross-border returns is big enough that 8 merchants will pay a $300 deposit on a 25% contingency service.
Riskiest assumption · A mid-size merchant's cross-border returns carry at least a few thousand dollars a quarter of recoverable duty and import VAT, enough to pay a 25% contingency fee and the broker's filing costs with margin left over.
1Focus group: who and where
Finance or operations lead at a US DTC brand doing $2-20M a year with 10-30% of orders shipped cross-border on DDP terms, who has watched prepaid duty and import VAT vanish on every international return since de minimis ended in 2025 and currently books the loss as an unexamined line in the P&L.
where to find 25 · The eCommerceFuel private forum for seven-figure store owners; the review sections of cross-border duty apps in the Shopify App Store (Zonos, Global-e, Passport), where these exact merchants describe returns pain by name; the NCBFAA member directory of licensed customs brokers as a referral channel; r/shopify for a wider net.
2Sell first, build later
A founding-filer slot: Dutyback files your duty drawback and import VAT reclaims on cross-border returns from the past 12 months and ongoing, through a licensed customs broker, with the first recovered money back in your account within 90 days of the cohort start on October 12, 2026.
the ask · 25% of recovered duty and VAT per reclaim, no recovery no fee, plus a $300 refundable cohort deposit credited against the first fee.
a real yes · A paid $300 deposit with a signed filing authorization counts. 'We lose so much on returns, keep us posted,' unpaid data sharing and audit requests without a deposit do not.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Return-leg recovery audit
$200 · 12 days
Recruit 12 merchants via an eCommerceFuel post and direct outreach to Shopify app reviewers who mention returns. Each shares 90 days of cross-border return data: order value, destination, duty and VAT paid, return route. Compute the recoverable amount per merchant against published US drawback and UK/EU import VAT reclaim rules, and send each a one-page audit result.
keep going if · 7 of 12 audits show at least $2,500 of recoverable duty and VAT per quarter
2. Broker cost floor check
$100 · 7 days
Call 8 licensed customs brokers from the NCBFAA directory and buy one paid consult hour with the sharpest. Get written quotes for drawback entries and import VAT reclaim filings at the parcel values found in experiment 1, batched across merchants.
keep going if · 3 of 8 brokers quote all-in filing costs under 40% of the median per-merchant quarterly reclaim from experiment 1
3. Founding-filer deposit pitch
$300 · 14 days
Pitch every audited merchant plus 15 more: a $300 refundable deposit reserves one of ten slots in the October founding cohort, fee of 25% of recovered money, deposit credited against the first fee. Take the money on a simple checkout page linked from the pitch email, with a signed one-page filing authorization.
keep going if · 8 paid $300 deposits from 25 pitches
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.
$300
per prospect, refundable
how · A $300 refundable reservation paid on a simple checkout page linked from the pitch, plus a signed one-page authorization letting the partner broker file on the merchant's behalf; small business owners will put a small refundable amount on a card for a contingency service where they would never sign an annual contract. set up: Stripe Checkout ↗
what it reserves · One of ten slots in the October founding cohort, the 25% founding fee locked for 12 months against a 35% list rate, and their trailing-year returns included in the first filing batch.
refund · Refunded in full, no questions, if the audit shows under $1,000 recoverable in their trailing year or if their first filing is not submitted within 60 days of cohort start.
target · 8 deposits of $300 from 25 pitches within 30 days
before taking money · Duty drawback and customs reclaims must be filed through a licensed customs broker under CBP's drawback process, so sign a broker partnership before taking any merchant authorization and file nothing in Dutyback's own name.
Go: build it if
7 of 12 audits clear $2,500 per quarter recoverable, at least 3 brokers keep filing costs under 40% of the median reclaim, and 8 merchants pay the $300 deposit within 4 weeks.
Kill: stop if
Median recoverable under $1,000 per quarter across the audits, or broker filing costs above 60% of the typical reclaim, or fewer than 3 deposits after 25 pitches - the card's stated risk confirmed in numbers: the parcels are too small to pay for the paperwork.

outreach message
You sell cross-border on DDP, so every international return quietly eats the duty and import VAT you prepaid, and nobody on your team has time to claim it back. I am building Dutyback: we file duty drawback and VAT reclaims on your returns through a licensed customs broker, and take 25% of whatever we recover, nothing if we recover nothing. First step is a free audit of 90 days of your return data that shows your exact number. Can I get 20 minutes this week?
landing page
Get back the duties and VAT you lose on international returns. No recovery, no fee: 25% of recovered money; a $300 refundable deposit reserves your cohort slot. Book your 90-day return audit and reserve an October slot.
deposit terms
Your $300 reserves one of ten slots in the October founding cohort and locks the 25% founding fee for 12 months; it is credited against your first recovery fee. If your audit shows under $1,000 recoverable in the trailing year, or your first filing is not submitted within 60 days of cohort start, the $300 comes back in full.

The concept in full
- What
- Dutyback is an agent service that handles the return leg of cross-border purchases made by AI agents: it files duty drawback and import VAT reclaims, computes the correct refund net of unrecoverable charges, and feeds the adjustment back to the merchant's books. Merchants selling internationally through agent surfaces stop eating duties on every return.
- Grounded in (2025-2026 signals)
- UCP announced January 11, 2026 with Shopify, Etsy, Wayfair, Target and Walmart; Shopify AI-driven store traffic up 8x and AI-search orders up nearly 13x in Q1 2026; ShipTag (500global 2025) handling duties and taxes for outbound cross-border e-commerce and HEVN (yc X26) doing cross-border payments for exporters, both forward-flow only; keyword coverage shows 'duties' at just 2 companies in the last two years.
- What it rides
- UCP: one checkout protocol for agents. UCP's live catalog queries and structured carts let agents buy across borders at scale, and Dutyback works the reclaim workflow those cross-border returns create.
- Why now
- Agent-driven orders grew nearly 13x year over year by Q1 2026 on Shopify alone, and returns follow orders with a lag measured in weeks; the brief shows only 2 companies in two years even mentioning 'duties', so the reclaim side of cross-border agent commerce is unowned.
- Wedge: first customer and entry point
- UK and EU merchants selling into the US through agent checkout; start with a per-reclaim fee service run largely by agents on top of existing customs broker filings for a handful of merchants, then automate the drawback paperwork.
- Closest real companies, as the generator saw them
- ShipTag handles cross-border duties and taxes on the outbound sale and Trava does AI agents for trade compliance; neither files reclaims on returns. HEVN moves exporter payments, not refunds.
- Main risk
- Per-merchant reclaim values on small parcel returns prove too low to cover filing costs, capping the model at large merchants a small team cannot reach.
