Multi-Marketplace Reporting on Amazon: A UK Seller's Guide

How UK sellers can combine sales, fees, ad spend and profit across Amazon marketplaces: which reports to use, how to handle currency and VAT, and what to check.

Multi-Marketplace Reporting on Amazon: A UK Seller's Guide

Seller comparing reports from multiple marketplaces

Multi-marketplace reporting means pulling sales, fees, advertising spend and profit from every Amazon store you sell in (Amazon.co.uk, Amazon.de, Amazon.fr and so on) into one consistent view. Amazon gives you building blocks for this, but no single report that answers “what did I actually earn, per marketplace, after everything?”. This guide shows which reports to combine, where currency, VAT and payout timing break the numbers, and how to automate the routine so you stop rebuilding spreadsheets every month.

TL;DR

  • One seller account can reach several European stores, but some expansions need a separate account. Your reporting has to know which marketplaces sit under which account.
  • Combine four data sets per marketplace: orders and sales, settlement or transaction data, advertising reports and costs of goods. Profit only appears when all four meet.
  • Fix your rules before you compare: one reporting currency, one date basis (posted date or payout date) and one treatment of VAT.
  • Amazon changed its Transaction and Summary reports in 2026 to include deferred transactions and index by posted date, so check that older exports still match.
  • Automate the pull through Amazon’s API, then spend your time on decisions, not on copying CSVs.

What multi-marketplace reporting actually covers

The phrase gets used for three different jobs, and it helps to separate them.

  1. Sales and traffic across stores. Units, revenue, page views and conversion by marketplace and ASIN.
  2. Advertising across countries. Spend, sales and ACOS or ROAS by country, ideally in one currency.
  3. Profit and cash. Fees, refunds, VAT, landed cost and payouts, reconciled to your accounts.

Most sellers start with the first, then discover that the third is where the real work is. A store can show healthy revenue and still lose money once FBA fees, returns, ad spend and currency movement are taken out.

Which marketplaces sit under one account

Amazon says a single seller account can sell to customers on Amazon.co.uk, Amazon.fr, Amazon.de, Amazon.it, Amazon.es, Amazon.pl, Amazon.nl, Amazon.se, Amazon.com.be and Amazon.ie, and that you can manage listings and inventory across Europe from that account. That is the easy case: one login, several storefronts.

The harder case is going beyond that region. Amazon’s international selling guide notes that entering another store, for example Amazon.co.jp from the UK or US, may require creating a new selling-partner account. Amazon’s own account-management programme documentation makes the same distinction: a unified account is charged once, while separate accounts can be selected and charged separately.

For reporting this matters, because separate accounts mean separate data sources, separate payouts and often a separate currency. If you are weighing up an expansion, a broader guide to scaling an ecommerce business internationally covers the planning side, while the account structure above decides how your numbers will have to be consolidated later.

Which marketplaces sit under one account

The reports you can combine

Seller Central is, in Amazon’s words, the console where you list products, track sales, view reports and message customers. It holds most of what you need, but the data is spread across several areas.

Question Where the data lives What to watch
What sold, where? Business reports and order reports per marketplace Marketplace filter, date range, currency
What did Amazon charge? Transaction, Summary and settlement reports Posted date versus payout date
What did ads cost? Amazon Ads campaign reports Country, currency conversion
Which pages convert? Page view and traffic reports by ASIN Coverage by marketplace
What VAT is due? Tax document library, VAT invoices Short maximum date range

Advertising: one report for several countries

Amazon Ads lets marketers generate a single campaign report for an ad programme across multiple countries in a region, such as Europe, and convert the metrics into a currency you choose. That feature was announced in September 2023, so confirm in your own console how it behaves today.

Agencies and larger sellers can also link country-specific advertising accounts into regional manager accounts. Amazon’s manager account user guide describes this as a consolidated view of metrics, billing and user management across the UK, France, Germany, Italy, Spain, the US and other countries.

If you want to compare how advertising and revenue data can be tied together outside Amazon too, analytics across multiple ecommerce sites shows the same single-view principle applied to web traffic and attribution. For the Amazon side, our own pages on PPC optimisation and Amazon Attribution reporting go deeper.

Traffic and page views via the API

Amazon’s Selling Partner API documentation lists a report type, MARKETPLACE_ASIN_PAGE_VIEW_METRICS, that provides page view data for ASINs across supported marketplaces, including the UK. This is the kind of source an automated tool uses so you do not download one file per store.

Settlement data: the part that trips people up

The V2 settlement report is tab-delimited, and sellers on the Amazon forums describe its amounts as normalised into amount-type, amount-description and amount columns. The practical lesson is to group rows by transaction type, amount type and amount description if you want to reproduce Amazon’s Summary PDF. The same thread shows sellers are unsure which time filter to apply, which is a reminder to document your own rule and keep to it.

Set your rules before you compare

Most reporting disputes (“why does this month not match?”) are really disagreements about rules. Decide these four once.

1. One reporting currency

Pick the currency of your books, usually GBP for a UK company. Convert every marketplace into it using a consistent rate, either the rate on the transaction date or a monthly average. Keep the original currency column as well, so you can tell a genuine sales drop from a weak euro.

2. One date basis

Amazon has acknowledged the problem here. In its announcement, it said sellers found reports based on payout timing hard to use for accrual reconciliation, especially when transactions were deferred. Between 23 March and 31 May 2026 it rolled out updated Transaction and Summary reports in the UK and a list of other stores that include deferred transactions and are indexed by posted date.

What that means for you: if you built a spreadsheet on older exports, re-run one past month with the updated reports and compare totals. If you want a refresher on when money actually lands, our guide to the Amazon payout schedule explains the timing.

3. One VAT treatment

Report sales and costs net of VAT for profit analysis, and keep a separate VAT view for compliance. Amazon forum guidance on invoices says to use Reports, then Tax document library, then Amazon VAT Invoices, and that the maximum date range is 7 days. That is an older community answer (around 2022), so check the current limit in your account, but it shows why bulk VAT reconciliation by hand is slow. We cover the accounting side in reconciling Amazon settlements for UK accounting and MTD.

4. One cost basis

Amazon does not know your landed cost, so product cost, inbound freight and duty have to come from you. Decide whether you use average cost or batch cost, and apply it everywhere. Without this, marketplace profit comparisons are only revenue comparisons with extra steps.

A simple monthly workflow

Here is a routine you can run by hand or hand over to software.

  1. Export or pull orders, transaction data and ad reports for each marketplace for the same posted-date range.
  2. Tag each row with marketplace, currency and account (unified or separate).
  3. Convert to your reporting currency and keep the originals.
  4. Allocate ad spend to ASINs and marketplaces. Shared campaigns need a rule, such as by sales share.
  5. Add costs of goods and inbound shipping per unit.
  6. Reconcile the net total against the payouts that reached your bank, allowing for deferred and reserved amounts.
  7. Compare marketplaces on profit per unit and profit margin, not on revenue.

If you keep your books in accounting software, note the limits of its Amazon connection. One UK cloud accounting provider’s guidance says its integration imports daily sales, refunds and fees from Amazon UK automatically, while transactions from non-UK stores such as Amazon.de must be uploaded or entered separately. It advises using separate accounts and contacts, with the currency and name matching each marketplace, to avoid reconciliation problems. In other words, your management reporting and your bookkeeping are two jobs, and each needs a clear structure per marketplace.

Worked example: why revenue misleads

Take a hypothetical seller with one product on Amazon.co.uk and Amazon.de. The figures below are invented to show the method, not real results.

UK Germany
Sales (net of VAT, in GBP) £10,000 £4,000
Amazon fees and FBA £3,000 £1,400
Advertising £1,500 £1,100
Product and inbound cost £3,500 £1,400
Profit £2,000 £100
Margin 20% 2.5%

Germany looks like a 40% sized business next to the UK when you read revenue. On profit it is almost nothing, mostly because ad spend is high relative to sales. A consolidated report makes that visible in one glance and points to a specific action: review the German campaigns before adding more stock there.

Data-quality checks that save you later

  • Missing marketplaces. Does the total include every store, including ones under a separate account?
  • Currency drift. Are all conversions using the same rate rule?
  • Deferred transactions. Do your month-end totals include them under the updated reports?
  • Refunds and returns. Are they assigned to the month of the refund or the month of the original sale? Choose one.
  • Ad attribution windows. If your attribution settings changed, year-on-year ad comparisons shift. See our note on the 2026 attribution window change.
  • API issues. If a report returns odd data through the API, Amazon Seller Support’s advice in community threads is to contact Selling Partner Developer Support.

Also look beyond money. Inventory health feeds back into cost, so a regular look at your IPI score and stock position by marketplace belongs in the same review.

Which marketplace should get your next pound?

Once the numbers are consolidated, use them for allocation. Rank marketplaces by profit per unit, by ad spend needed per sale and by stock turn. A store with a lower margin but fast-selling stock may deserve more investment than a high-margin store that barely moves. Demand signals also help: our article on search query performance shows how to read Amazon’s funnel data by query, and the competitor keyword workflow helps you find terms to target in a new store.

Our view: stop assembling, start deciding

We built Osellpa because sellers kept telling us the same thing: the data exists, but making sense of it eats the week. A part-time seller with one store and a large seller with several both end up in spreadsheets, copying exports and hoping the formulas still hold after Amazon changes a report.

Our approach is to connect directly to Amazon’s API and keep profit, advertising and inventory data in one place, so the numbers update without manual exports. We think the order of work matters. First, see your true profit. Second, let automation handle repetitive PPC adjustments and alerts. Third, improve listings with that evidence in hand.

We also believe this should not be reserved for enterprise budgets. That is why our plans are priced by seller size and start at a level a new seller can justify. If your reporting currently depends on one person who understands the spreadsheet, that is the process worth replacing first.

FAQ

Can I see all my Amazon marketplaces in one report?

Partly, from Amazon alone. Advertising reports can combine countries within a region and convert currency, and one unified account covers several European stores. Profit across marketplaces, including fees, VAT and your product costs, usually needs data from several reports brought together by you or by software.

Why do my Amazon totals not match my bank payouts?

Because payouts reflect timing, reserves and deferred transactions, while sales reports reflect the order or posted date. Amazon updated its Transaction and Summary reports in 2026 to include deferred transactions and to index by posted date. Pick one date basis and reconcile the difference as a timing line.

Do I need a separate account for each marketplace?

Not within Amazon’s European network, where one account can reach the UK and EU stores. Some other regions, such as Japan, may require a new selling-partner account, according to Amazon’s international selling guide. Separate accounts mean separate data to merge, so record which account each store belongs to.

Which currency should I report in?

Use the currency of your accounts, normally GBP for a UK business, and keep the original marketplace currency beside it. Apply one conversion rule consistently, whether that is transaction-date or monthly average rates, so month-to-month comparisons stay fair.
