Proof of delivery and the taxman: why resellers must archive every POD

Picture a reseller with a year of shipments behind them — a hundred-plus tracking numbers spread across a couple of busy quarters — who suddenly needs the proof of delivery for all of them at once. Not because a buyer complained, but because someone official asked a question about those sales. They start pulling tracking numbers into carrier websites and hit a wall: the older ones show nothing. The delivery happened; the record of it is gone. Now they're paying people to chase carrier customer service for documents that may simply no longer exist.

That situation is entirely avoidable, and it comes down to one habit: treating proof of delivery as something you archive continuously, not something you go and find when it's demanded. This piece is about why that demand comes — and why the clock on it is much shorter than you'd think.

The reason is VAT, and specifically the treatment of goods that cross a border. When you sell to a buyer in another country, the VAT you charge — or don't — usually depends on the goods actually leaving yours. In the EU, zero-rating a cross-border supply hinges on being able to show the goods were dispatched or transported out of your country; for exports outside the EU, the equivalent is proof the goods were exported. That's a documentary condition, not a formality.

The consequence of not being able to prove it is the part that stings. If a tax authority questions a cross-border sale and you can't produce evidence the goods actually moved, they can deny the favourable VAT treatment and treat the sale as if domestic VAT was due — which means assessing that VAT against you, often with interest and penalties on top. You didn't do anything wrong; you sold and shipped a real pair to a real buyer. But "I shipped it" and "here is the proof it was delivered" are very different positions to argue an audit from, and only one of them wins.

Tax authorities don't usually accept a single self-made note that something shipped. The EU framework (the 2020 "quick fixes" and the presumption in the VAT Implementing Regulation) leans on holding multiple, independent pieces of evidence that don't contradict each other — typically two items from parties independent of you and the buyer. In practice, for a reseller, that evidence set is built from things like:

• The carrier's proof of delivery — the tracked, timestamped record that the parcel reached its destination.
• The shipping documentation — the carrier invoice or transport document (a CMR for road freight) showing the movement.
• The sale and invoice — tying the shipment to a specific order and buyer.

Courts have accepted that the exact list isn't rigid — what matters is that, taken together, your documents genuinely establish the goods moved. But the carrier POD is the anchor of that set. It's the independent, hard-to-dispute record, and it's also the one you're most likely to lose.

Here's the mismatch that catches resellers out. A tax authority can look back over multiple years — record-keeping obligations for VAT commonly run to several years, and an audit can land well after a sale. Your carrier, meanwhile, keeps the proof of delivery available for a tiny fraction of that time.

UPS, for example, surfaces detailed tracking and proof of delivery through its own tools for only around 90 to 120 days; past that you're reduced to asking customer service, which is slow and far from guaranteed. Other carriers vary, but the pattern holds: self-serve access to POD is measured in months, while your obligation to have it is measured in years. So the document a tax office might ask for in 2027 is one your carrier may have stopped showing you in early 2024. That gap is precisely why the reseller in the opening scramble couldn't recover their older deliveries — the records aged out of reach long before anyone asked for them.

The solution isn't complicated, it's just a habit: pull the proof of delivery for every batch you ship, promptly, and keep your own copy. Done per shipment it's a chore that never gets done; done in bulk on a schedule it's a few minutes a week. The goal is a private archive of PODs that doesn't depend on any carrier still showing them.

This is exactly what the POD Downloader is for. Paste your tracking numbers or tracking URLs, pick a carrier (or let Auto-detect handle a mixed batch across UPS, DHL and DPD), and it downloads every proof-of-delivery PDF into one folder, named by tracking number. It de-duplicates, skips files already saved, and on a re-run only retries the ones that failed — so you can keep feeding it a growing list session after session and build the archive cheaply.

On consignment and platform-driven sales — StockX and the like — it's tempting to assume the marketplace holds all the records, so you don't have to. Be careful with that assumption. You're the one making the sale for tax purposes, which means you're the one who may need to evidence it, and a marketplace's own retention and willingness to hand you a delivery document on demand years later is not something to bank your VAT position on.

The safer posture is to capture the tracking and pull the POD at the time you ship, while the shipment is fresh and the carrier still shows it — the same moment your label was generated and your pickup scheduled. Read the companion piece, shipping labels & proof of delivery, for how the label, pickup and POD chain together from a single confirmed sale so nothing is left to recover later.

An archive of loose PDFs is better than nothing, but it's not the goal. The goal is that for any sale you can produce the invoice, the payout and the proof of delivery together, quickly. When those three live alongside each other — the POD filed against the order and its invoice rather than scattered across carrier accounts — an audit query becomes a lookup instead of an investigation, and your VAT treatment is backed by a complete, coherent record.

That's the same discipline that runs through reseller bookkeeping generally: the paperwork should fall out of operating, and it should reconcile. If you're setting this up properly, pair this with VAT for sneaker resellers for how the margin scheme and standard VAT change what your records need to show, and bookkeeping for high-volume resellers for the wider record-keeping setup.

You don't need a system to get this right, just a policy you actually follow:

1. Pull POD weekly for everything shipped that week, in bulk, while the carriers still show it.
2. Archive it named by tracking number, filed with (or linked to) the sale and invoice it belongs to.
3. Keep it for as long as your invoices — VAT record-keeping periods vary by country and commonly run several years, so match the POD retention to whatever your invoices require.
4. Back the archive up somewhere that isn't one laptop, because the whole point is that it survives until someone asks.

Do that and the audit scramble simply never happens. The proof was captured the week the parcel moved, it's sitting with the sale, and producing it is a search rather than a rescue mission.
