A2X vs Link My Books for Ecommerce Sellers

A marketplace payout landing in Xero is not the same as a set of reliable accounts. For a growing ecommerce business, the difference sits in the detail: VAT on sales and fees, refunds, shipping charges, reserve balances, payment timing and the way each settlement reconciles to the bank. Choosing between A2X vs Link My Books is therefore less about finding the most feature-packed app and more about building a bookkeeping process that produces dependable numbers.

Both tools can reduce manual marketplace bookkeeping. Both are designed to turn complex sales-channel data into accounting entries that are easier to reconcile. The right choice depends on where you sell, your VAT position, the level of reporting detail you need and how your finance function is organised.

Why marketplace settlements create accounting problems

Amazon, Shopify, eBay and other channels rarely pay sellers the exact amount shown as sales revenue. A single payout can include product sales, VAT, delivery income, refunds, referral fees, fulfilment fees, advertising charges, chargebacks and adjustments. If the net deposit is posted straight to sales, turnover, VAT and gross margin can all be misstated.

This may not be obvious when order volumes are low. As sales increase, however, small posting errors become repeated errors. They affect VAT return figures, management reporting, stock-margin analysis and the time required to answer an accountant's questions at year end.

A good integration should create a clear audit trail between marketplace activity, settlement reports, a clearing account and the amount received in the bank. It should also apply the appropriate VAT treatment consistently, rather than relying on manual journals prepared after the event.

A2X vs Link My Books: the core difference

A2X is generally suited to sellers who want structured settlement accounting across multiple channels and, often, multiple territories. It extracts marketplace data and posts summarised entries to accounting software, separating the sales, fees, refunds, taxes and other settlement components needed for reconciliation.

Link My Books is particularly well known among UK Amazon sellers using Xero. Its proposition is focused on converting Amazon settlements into reconciled accounting entries while helping sellers apply VAT rules appropriately. It can be an attractive option where Amazon is the central sales channel and the business wants a practical, VAT-conscious workflow without building a highly customised bookkeeping system.

The distinction is not absolute. Both products have developed their channel support and functionality over time, so the current integrations, plans and country coverage should always be checked against your actual sales channels. The more useful question is whether the app handles your transaction flow accurately and produces entries your accountant can review efficiently.

Where A2X may be the better fit

A2X is often a strong choice for businesses with a broader ecommerce operation. If you sell through Amazon alongside Shopify, eBay or other marketplaces, the ability to establish a consistent settlement-accounting approach across channels can be valuable. This becomes more important when management wants comparable gross-margin reporting rather than separate spreadsheets for each platform.

It can also suit businesses trading internationally. Cross-border sales introduce complications around currencies, marketplace fees, VAT registrations and the treatment of taxes collected by a marketplace. The accounting system still needs to show a coherent picture of revenue and liabilities, even when sales are made across several storefronts.

For a finance team or outsourced accounting partner, A2X may offer useful control where the priority is repeatable processes at scale. A well-designed chart of accounts and mapping structure can separate income streams and cost categories without requiring the bookkeeper to rebuild every settlement manually.

That said, greater flexibility brings a responsibility to configure the system carefully. Mapping should reflect the commercial information directors need, not simply every data field available. Too much granularity can leave Xero cluttered with accounts that do not improve decision-making.

Where Link My Books may be the better fit

Link My Books can be particularly effective for a UK business whose accounting challenge centres on Amazon settlements and VAT treatment. For many owner-managed sellers, that is exactly the issue they need to solve: how to turn Amazon's reports into a clear sales, VAT, fees and payout record that reconciles properly in Xero.

Its appeal is often practical rather than theoretical. A seller wants to know that the bank receipt matches the settlement, Amazon fees are recorded as costs, refunds reduce revenue correctly and VAT reporting is based on a defensible treatment of the underlying transactions. A focused tool can make this process more manageable.

It may be the more proportionate choice where sales are concentrated on one principal marketplace and the business does not need extensive multi-channel reporting. This does not mean it is only appropriate for smaller businesses. A high-volume Amazon seller can benefit from a focused workflow, provided it supports the VAT registrations, sales territories and reporting requirements involved.

The limitation arises when the business model changes. If Shopify becomes a major channel, additional marketplaces are added, or international expansion accelerates, it is sensible to revisit whether the existing app structure still provides a complete view of trading.

VAT is the deciding factor more often than price

For UK ecommerce businesses, VAT should carry significant weight in the decision. The correct treatment can depend on where goods are located, where customers are based, whether the marketplace is deemed to be the supplier for certain transactions, and whether the business holds overseas VAT registrations. A software subscription cannot replace a review of these obligations.

The risk is not only underpaying VAT. Incorrect mapping can also overstate VAT due, distort reported turnover or leave the business unable to explain figures to HMRC. This is especially relevant for sellers using Fulfilment by Amazon, holding stock outside the UK or making sales through EU marketplaces.

Before selecting either tool, test how it deals with your real settlement data. Review a completed settlement containing sales, refunds, promotional discounts, fees and VAT. Then confirm that the postings reconcile to the payout and are reflected correctly in the VAT return. A demonstration based on a simple domestic sale is not enough for a business with cross-border activity.

Questions to ask before choosing

The best decision usually comes from mapping the journey from customer order to bank receipt. Consider where sales are made, where stock is held, which VAT registrations apply and what reporting the directors need each month. Then assess each app against that workflow.

Ask whether it supports every sales channel that matters now, not only the largest one. Establish whether it posts by settlement rather than individual order, how it handles refunds and reserves, and whether multicurrency payouts can be reconciled cleanly. Check the level of detail shown in Xero and whether that detail is useful for your management accounts.

Also consider who will own the process. An app does not remove the need for review. Someone should check that settlements are importing, clearing accounts are reconciling, VAT codes remain appropriate and new marketplace charges have not been posted incorrectly. Clear responsibility is particularly important when bookkeeping is shared between an internal team and an external adviser.

Build the app into a controlled finance process

Neither A2X nor Link My Books should be treated as a set-and-forget solution. The software can automate data capture and posting, but commercial control comes from the process around it. Monthly checks should compare marketplace sales to accounting records, investigate aged balances in clearing accounts and review gross margins by channel.

This is also the point at which ecommerce accounting becomes more useful than compliance. Once sales, fees and refunds are classified consistently, directors can see whether growth is translating into retained profit. They can identify rising fulfilment costs, monitor the effect of discounts and make better decisions about pricing, stock purchases and advertising spend.

For businesses using Xero, a specialist ecommerce accounting setup can ensure the chosen app, chart of accounts and VAT process work together rather than creating another layer of administration. Fortis Accounting helps ecommerce owners turn marketplace data into current, decision-ready financial information, with the professional oversight needed as trading becomes more complex.

The practical choice is the tool that accurately reflects your sales journey today while leaving room for the business you intend to build. Start with clean reconciliation and correct VAT treatment. Everything else in the management accounts becomes more reliable from there.
