Free Ecommerce Audit UK: A Ranked Fix List From the Checkout to Xero
Your store takes orders every day, but sales have flattened or staff fix overnight errors each morning. We follow real orders from the checkout on a phone to the sale in Xero, Sage or NetSuite. You get one list, ranked by what each fix is worth.

An ecommerce website audit for a trading UK store follows real orders from the checkout to the bank. It tests speed, checkout and price display against Google and CMA guidance, compares stock and listings across marketplaces, and traces each sale, refund and payout into Xero, Sage, QuickBooks or the ERP. The result is a written list of fixes, ranked by value and effort, with the evidence for each.
Drip pricing is the CMA’s name for charges added as a shopper moves through a purchase. A digital link is HMRC’s term for data moved between software by API or file import, never by copy and paste. An ERP is the single system that holds stock, purchase orders and the ledger, such as NetSuite, Business Central or Odoo.

Signs a trading store needs an audit before it needs more traffic
Buying more traffic into a store with a leak only makes the leak bigger. Each of the six signs below points to a different leak.
- Revenue grew, margin did not. Marketplace fees, returns and courier surcharges ate the extra orders, and nobody can show profit by channel.
- Staff retype orders. Amazon, eBay or trade orders get keyed into Sage, Xero or the ERP by hand, and errors appear at month end.
- Stock disagrees with itself. Shopify, Linnworks and the warehouse show three numbers, and peak season brings oversells and cancellations.
- Payouts never match the bank. Stripe, Klarna or Shopify Payments deposits arrive net of fees and refunds, and the bookkeeper reconciles them by hand.
- Checkout drop-off is high on mobile. Shoppers reach the basket and leave, and the analytics cannot say where.
- An agency wants to rebuild everything. You want an evidence-led view of what is broken before you sign a six-figure replatform.
For the bigger strategic questions, our UK ecommerce consultant service is the better fit. If the audit shows the design is the real problem, the work moves to an ecommerce redesign. If only search is weak, the UK SEO audit goes deeper there. Fixes that need new store code go to our Shopify development or UK ecommerce development teams.
Ten areas an ecommerce website audit should cover, in the order we check them
Money first, because the rest of the list is ranked by it. Every area ends with findings you can check yourself: an order number, a screenshot, a log line or a report export.
- 01
Profit per order, by channel
Your own site, Amazon.co.uk, eBay UK, OnBuy and trade orders, each net of fees, returns, delivery and ad spend. The channel that looks biggest is not always the one that pays.
- 02
The checkout on a real phone
We buy, change the basket, use a discount code and pay with a card, a wallet and Klarna or Clearpay where you offer them. Every extra field and every charge that appears late goes on the list.
- 03
Prices shown against UK rules
Headline prices, delivery charges and fees compared with the CMA price transparency guidance and the GOV.UK pre-purchase information list, screen by screen.
- 04
Speed against Google’s thresholds
Main content, tap response and layout shift on the home, category, product and basket pages, with the app, script or image behind each miss named.
- 05
Product data and search
Titles, variants, GTINs (the barcode numbers marketplaces ask for), stock messages and structured data. The same data feeds Google Shopping, marketplaces and AI answers, so one fix pays three times.
- 06
Stock between every channel
Where the stock number lives (Shopify, Linnworks, Brightpearl, Mintsoft, Odoo or the ERP), how often each channel reads it, and how many oversells and cancellations that caused last month.
- 07
Orders into the books
Each sale, refund, fee and payout followed into Xero, Sage, QuickBooks UK, NetSuite or Business Central. We mark every manual step, which also matters for HMRC digital links.
- 08
Couriers, labels and returns
Royal Mail, DPD, Evri or your 3PL (the outside warehouse that picks and posts orders): delivery promises against real transit times, label creation, tracking emails and the cost of a returned parcel.
- 09
Tracking, cookies and consent
Every tag the store fires, sorted into analytics or advertising, checked against the ICO’s guidance, and tested to see whether purchases are counted once and only once.
- 10
The platform’s next three years
Whether the current platform carries your plans for trade, new markets or more channels, or whether the fixes are turning into workarounds.
Four UK rules a store audit should check, and what each one means at checkout
An audit from a generic checklist misses these, because they live in GOV.UK, CMA, HMRC and ICO guidance rather than in a speed report. We read each one on the regulator’s own page and test your store against it.
1. Price transparency and drip pricing (CMA)
The CMA published its price transparency guidance on 18 November 2025 and updated the page on 7 January 2026. It names drip pricing, where charges are added as a shopper proceeds, as a practice to avoid. The same day it opened investigations into 8 businesses, sent advisory letters to 100 firms, and said fines can reach 10% of global turnover. In the audit we screenshot the price at each step, from the product page to the payment screen, and list any charge that was not visible at the start.
2. Cancellation rights and pre-purchase information (GOV.UK)
The GOV.UK guidance sets a 14-day cancellation right after delivery for most online orders, which stretches to 12 months if the seller never mentions it. It also lists what a shopper must see before paying, including a price with all taxes included and delivery costs. From our test order we capture the order-confirmation email and the returns-portal screen, then mark each item on that list as shown or missing.
3. Digital links for VAT records (HMRC)
VAT Notice 700/22, paragraph 3.2.1, accepts API transfers, CSV imports, linked spreadsheet cells and emailed spreadsheets as digital links. It says cut and paste or copy and paste does not count. So when a person types last week’s Amazon payout into Xero or Sage, we flag it as a step your accountant should check against para 3.2.1, which also covers when manual entry is allowed. We mark every such step on the order map.
4. Cookies and analytics (ICO)
The ICO says the Data (Use and Access) Act 2025 lets organisations set some cookies without consent, including ones that collect statistical information. Its guidance sets conditions. The data must be aggregate, and users must get clear information plus a simple, free way to object. The exception does not apply to online advertising, including ad measurement. We list every tag your store fires and sort it into one side or the other.

Send the store address, the channels you sell on and the systems behind them. We reply with a written scope for your free audit. Attach your brief or request for proposal (RFP) at step 2.
How we run an ecommerce audit, in seven steps
The steps stay the same for a Shopify brand and a WooCommerce wholesaler. Only the systems in step four change. Your finance lead joins us for steps four and seven.
- 01
Scope call with the founder
Channels, systems, order volume and what worries you. We agree what is in scope and the timeline, in writing, before any login is shared. The audit is free.
- 02
Read-only access
Analytics, Search Console, the store admin as a staff user, a viewer login for the books and, where relevant, Linnworks, Brightpearl or Mintsoft. No write access, ever.
- 03
Buy, change and refund
Agreed test orders on a phone and a laptop, with a discount, a part refund and each payment method you offer. Each one is refunded and labelled so it never skews your figures.
- 04
Follow every order into the back office
Each test order traced through stock, the courier label, the payout and the entry in Xero, Sage, QuickBooks UK, NetSuite, Business Central or Odoo.
- 05
Talk to the people who run the shop
Half an hour each with customer service, the warehouse and finance. Workarounds people stopped noticing show up here.
- 06
Rank by value and effort
Every finding gets evidence, a likely cost of leaving it, the effort to fix it and an owner. The list is sorted so the top five are this month’s work.
- 07
Walkthrough and hand-over
A call with the founder through the report, then the document is yours. Your team, your agency or ours can pick it up, and you remove our logins the same day.
Terms for the audit, and for any work that follows
They are written into the proposal before work starts, and they do not change if the audit leads to a build.
- The audit is free. Scoped on the first call and confirmed in writing before you share a single login.
- The report is yours. Written so any team can act on it. You are never tied to us for the fixes.
- Working software on your own data before you sign a build. If you ask us to fix something, we show it on your real products or orders first.
- A fixed price per phase. Each phase is scoped, priced and signed on its own, so you can stop after any one of them.
- You own it from day one. The code and the repository are yours. Hosting and apps can run in your own accounts at cost, with no markup.
- Defects fixed inside the build price. For a cover period we agree before work starts. Support after that is optional, quoted per change, with no monthly minimum.
UK trade store projects behind this audit method
Both projects are about what happens after the click: account prices, stock held in another system, and orders that must reach the back office without retyping. That is the part of a store most audits skip.
GPSUK, built on Commerceflo
A trade storefront where UK business buyers log in, see their own account prices and move from quote to order without retyping. SEO and AI search work continues. Read the GPSUK case study.
Sow Easy, WooCommerce joined to Odoo
A wholesale store on WordPress WooCommerce, built to read stock, pricing and SKUs (product codes) from Odoo. The Odoo link is tested against Odoo’s staging system, and launch is still ahead. Read the Sow Easy case study.
For trade ordering in more depth, see B2B ecommerce in the UK. Where an audit finds Shopify sales reaching Xero as one line, the fix usually sits in a Shopify Xero integration. When orders have to reach Sage, NetSuite, Business Central or Odoo, the work is ecommerce ERP integration.
Ecommerce audit options compared: a tool, an agency pitch audit, or a traced audit
Each has a use. The difference is how far past the storefront each one looks.
Swipe sideways to see every column.
| What you get | Traced audit (FactoryJet) | Automated audit tool | Pre-sales audit from a build agency |
|---|---|---|---|
| Looks past the storefront | Stock, couriers, payouts, books | Public pages only | Usually the site only |
| Places real orders | Yes, agreed and refunded | No | Sometimes |
| UK rule checks | CMA, GOV.UK, HMRC, ICO | Cookie scan at most | Varies, ask |
| Ranked by money | Value and effort on each fix | Severity scores | Often ranked toward a rebuild |
| Usable by another team | Written to hand over | Yes | Tied to their proposal |
| Price shape | Free, with the scope in writing | Free or a subscription | Often folded into a build quote |
The table reflects how each option usually works for UK stores in October 2026. Automated audit tool means crawlers and speed tests such as Google PageSpeed Insights, Screaming Frog, Semrush Site Audit or Ahrefs Site Audit. The table does not score any one of them.
What an ecommerce audit costs in the UK
No price list exists, because audit means anything from a one-hour screen recording to weeks of order tracing. The nearest published UK reference is for SEO audits: Red Eagle Tech, a North London agency, puts one-off SEO audits at £500 to £7.5k, and £5k to £15k+ for sites over 500 pages, in its guide updated 9 July 2026. The guide does not say whether those figures include VAT, so ask any supplier whether a quote is ex or inc VAT before you compare.
An audit that follows orders into stock, couriers and the books has more scope than an SEO audit. Four things move it: the number of channels, the number of systems, order volume, and whether trade ordering is included. Those set how long the FactoryJet audit takes, not what it costs: the audit is free, and the scope is agreed in writing on a short call first.

Ecommerce audit questions from UK retailers, brands and wholesalers
What an audit is
What is an ecommerce audit?
An ecommerce audit is a written check of a live online store and the systems behind it. We test the checkout, page speed, product data, marketplaces, tracking, and the links to stock, couriers and accounts. Every finding comes with evidence you can open yourself, the likely cost of leaving it, and the effort to fix it. The output is one ranked list, so your team knows what to do on Monday.
How do you do a store audit?
Start with data, then walk the store as a buyer. We read analytics, Search Console and a month of orders and returns. Then we place real orders on a phone and a laptop, refund one, and follow each order through stock, the courier label and the accounting entry. Last, we interview the people who run the shop. We write down every gap between what the data says and what staff describe.
Who is this ecommerce audit for?
Established UK businesses with a store that already takes orders every day: brands, retailers, wholesalers and manufacturers selling direct or to trade. It fits best when you sell on more than one channel, such as your own site plus Amazon.co.uk or eBay, with an accounting or ERP system behind it. If the store is not live yet, a launch plan is a better first step than an audit.
How is this different from an SEO audit?
An SEO audit asks whether search engines can find and rank your pages. An ecommerce audit asks whether the business behind those pages makes money on each order: checkout, pricing display, stock accuracy, courier costs, refunds and the books. Search is one section of ours. If search turns out to be your biggest gap, our UK SEO audit goes deeper on crawling, indexing and AI search visibility.
Can ChatGPT or an automated tool audit my store?
Either is a sensible first check. A crawler such as Screaming Frog and a speed test such as Google PageSpeed Insights will, between them, flag slow pages, missing tags and broken links in minutes, and ChatGPT can explain what those reports mean. Neither can place an order, see that a Klarna refund never reached Xero, or notice that staff retype Amazon orders into Sage every morning. Those gaps need a person who follows the order end to end.
What we check
Which platforms do you audit?
Shopify and Shopify Plus, WooCommerce, Adobe Commerce (Magento), BigCommerce and custom storefronts. Behind the store we read Xero, Sage 50, Sage 200 and Sage Intacct, QuickBooks UK, NetSuite, Dynamics 365 Business Central and Odoo, plus Brightpearl, Linnworks and Mintsoft for orders and stock. The method stays the same on every platform. The weak points differ, so the checklist adjusts.
Why is my Shopify store running so slowly?
Common causes are apps that each load their own scripts, oversized product images and a theme that renders too much before the first product appears. Google’s Web Vitals guidance says the main content should appear within 2.5 seconds and a tap should get a response within 200 milliseconds, measured at the 75th percentile. We name the scripts and images behind each miss.
What does a Shopify store audit check?
A Shopify audit uses the same ten areas, plus checks that only apply on Shopify. We list every installed app and the scripts each one loads, test the theme on a phone, and follow Shopify Payments payouts into Xero or Sage. If you sell to trade buyers or to other countries, we check how prices and stock are set for each group. Each finding names the app, setting or theme file behind it.
Do you check marketplaces such as Amazon.co.uk, eBay and OnBuy?
Yes. We compare listings, prices and stock across your own store and Amazon.co.uk, eBay UK, OnBuy, ManoMano or the B&Q marketplace, wherever you sell. We look for oversells from slow stock syncs, fees that make one channel lose money once returns are counted, and marketplace sales reaching the books as one lump with no VAT split.
Do you look at payments and refunds?
Yes. We map how Stripe, PayPal, Shopify Payments, Klarna, Clearpay and GoCardless pay out, and whether each payout, fee and refund lands in the books against the right sale. Our test orders include a buy now, pay later refund and a part refund, so we can see whether each one lands against the original sale. We also check which payment options appear on a phone at checkout, because a missing wallet is an easy sale to lose.
Do you check couriers and delivery promises?
Yes. We compare the delivery dates and prices shown on product pages and at checkout with what Royal Mail, DPD, Evri or your 3PL (the outside warehouse that picks and posts your orders) actually deliver. We look at cut-off times, how labels are created, how tracking reaches the customer and what a returned parcel costs, because delivery promises drive both conversion and complaints.
Can you audit a B2B or trade store?
Yes. A trade store adds account pricing, credit terms, minimum order quantities, quotes and invoices on terms. We check whether trade buyers see their own prices, whether orders reach the ERP without retyping, and whether invoices and payments match. Our work for GPSUK on Commerceflo and the Sow Easy WooCommerce and Odoo build both sit in this kind of trade ordering.
UK rules and tax
Does the audit check the CMA rules on drip pricing?
Yes. The CMA’s price transparency guidance, published 18 November 2025, describes drip pricing as prices added as a shopper moves through a purchase. The same day the CMA said it can fine companies up to 10% of global turnover. We walk your checkout and list every charge that first appears after the product page, such as a mandatory fee or a delivery charge shown late, so your team and lawyers can decide what to change.
What does the audit check on returns and cancellations?
Under GOV.UK rules, shoppers must be told about a right to cancel most online orders up to 14 days after delivery, and the window grows to 12 months when nobody tells them. We screenshot the order-confirmation email and the returns-portal screen from our own test order and mark whether each one states that right, a price with all taxes included and the delivery cost.
Do you check our cookies and analytics after the Data (Use and Access) Act 2025?
Yes. The ICO says the Data (Use and Access) Act 2025 lets you set some cookies without consent, including ones that collect statistical information. Its guidance also says that exception does not cover online advertising, such as ad measurement. We list every tag your store fires, sort each into analytics or advertising, and check your banner. Your data protection lead makes the final call.
How does Making Tax Digital affect an online store?
HMRC’s VAT Notice 700/22 says records moved between software must use digital links, such as an API transfer or a CSV import, and that copy and paste does not count. We look for the places a person types sales, marketplace payouts or refunds from one screen into Xero, Sage or QuickBooks by hand. Your accountant confirms the fix against the notice.
Do you check how we sell to shoppers in the EU?
We map how EU orders are priced, taxed and shipped, and where that information sits in your systems, then hand the questions to your accountant, because VAT treatment depends on your set-up. If your store uses an AI chatbot or recommendations for EU shoppers, we list it so your legal team can check it against EU rules, including the EU AI Act. Both calls belong to a qualified adviser, and the report says so.
Cost and terms
How much does an ecommerce audit cost in the UK?
There is no standard price, because the word audit covers anything from an automated report to weeks of work. The nearest published reference is for SEO audits: Red Eagle Tech, a North London agency, puts one-off SEO audits at £500 to £7.5k, and £5k to £15k+ for sites over 500 pages (updated 9 July 2026, VAT not stated). An ecommerce audit that also covers systems and operations goes further than that. The FactoryJet audit is free: no fee for the scope call, the report or the walkthrough.
Is the audit really free, and why?
Yes. You pay nothing for the scope call, the test orders we agree with you, the written report or the walkthrough with the founder, and you keep the report whatever you decide. We offer it free because a ranked list of real findings from your own store shows how we work better than any sales call. Some stores hand the list to their own team. Others ask us to quote for the fixes.
How long does the audit take?
Three inputs set the timeline: how many systems an order passes through, how fast the read-only logins arrive, and whether trade ordering is in scope. Each extra system adds another hop to trace with test orders. Logins that take a week to arrive add a week. We put the agreed dates in writing with the scope, before work starts.
What access do you need, and is our data safe?
Read-only access is enough: analytics, Search Console, the store admin as a staff user and a viewer login for the accounting system. We never need write access to audit. You can remove every login the day the report lands. If a test order is needed, we agree it with you first and refund it, so it does not distort your sales or stock figures.
What do we sign up to if we hire you after the audit?
The audit is free, and its scope is agreed in writing before work starts. If you then ask us to fix things, each phase has a fixed price, quoted in writing and signed on its own. Changes are quoted and approved per request. You own the code and the repository from day one, defects are fixed inside the build price for an agreed cover period, and support is optional, quoted per change, with no monthly minimum.
After the report
What do we get at the end?
A written report and a walkthrough call with the founder. Each finding has the evidence (a screenshot, an order number or a log line), the likely cost of leaving it, the effort to fix it and who should do it: your team, your current agency, a supplier or us. The list is ranked, so the first five items are the ones worth starting this month.
Do we have to use FactoryJet to fix the findings?
No. The report is written so your own developers, your current agency or a freelancer can act on it. If you hire us for the fixes, the same people who wrote the report do the work, priced phase by phase, and nothing starts until you sign that phase.
What if the audit says we should replatform?
We say so only when the evidence points there, and we show what staying would cost next to what moving would involve: redirects, customer accounts, order history and every integration. We recommend a move only when fixing in place would cost more than moving. When a move is right, our Shopify migration team plans redirects and data first, so rankings and order history survive the switch.
Find the fixes your store is already paying for
Send your name and work email. The founder replies within 24 hours to book a scope call about your channels, your systems and what is going wrong. You leave with a written scope for a free audit, and no obligation to hire us for the fixes.
