Is Shopify's Facebook & Instagram app accurate?

It is accurate about what Meta can see, which is not every order your shop takes — so the purchase figures in Ads Manager will not line up with your Shopify orders, and that difference is normal rather than a sign something is broken.

What does the app actually measure?

The app connects your shop to Meta, sets up the pixel and the Conversions API, syncs your product catalogue and feeds purchase events back to Ads Manager. What arrives there is the set of purchases Meta was able to match to someone who clicked or saw one of your ads, inside the attribution window you have set. It is a count of credited sales, not a count of your sales.

Why doesn't it match my Shopify orders?

Several reasons stack up, and most of them are design rather than error. Meta dates a purchase to the ad interaction, so a sale from a click on the 29th can sit on the 29th in Ads Manager while Shopify records the order on the 1st. Browser tracking is blocked or declined by a share of shoppers, and your consent settings decide what gets sent at all. The pixel and the Conversions API both report, and the deduplication between them is not perfect. Meta does not see refunds, cancellations or failed payments, so an order that came back still counts. Your ad account and your shop can also sit in different time zones, which moves whole days around.

Does that mean the app is broken?

Usually not, though it is worth checking. Confirm the pixel and dataset are the ones you intend to use, confirm the ad account and the shop are on the same time zone, and confirm the attribution setting you are reading is the one you think it is. If the figures are still wildly apart after that — a handful of credited purchases against dozens of orders — something is wired wrong and is worth looking at properly.

What we've seen in practice

The gap bothers merchants less than not knowing how big it is. A merchant writing on the Shopify Community in January 2026 said that "only about 60% of purchases are tracked, making me hesitant to scale since the data in Ads Manager seems inaccurate." That is the real cost of it: budget decisions get postponed, not because the ads are failing but because nobody can say what they did. Shops that reconcile one finished week by hand — Meta's reported purchases against Shopify's orders for the same dates — generally stop arguing with the dashboard. They know their own gap and they take roughly that much off the figure.

Which number should I use to make decisions?

Your shop's orders for anything to do with money: revenue, refunds, what you actually kept. Ads Manager for direction: which creative and which audience are getting attention. The confusion usually starts when the ad platform's own score of its contribution gets treated as the accounts.

Compass reports from the store side — orders, refunds, costs and fees — so the revenue figure you work from is the one the shop actually took.

A small business website in the UK typically costs between £500 and £5,000 to build. A simple brochure site of five to ten pages sits around £1,000 to £2,500. A custom design or ecommerce build runs £3,500 upwards. Ongoing costs are separate: hosting, maintenance and SEO are usually charged monthly. What you're actually paying for Most of the cost is time, not software. Web designers posting their own rates on UK business forums put it around £50 an hour. A straightforward brochure site is roughly eighteen to twenty-five hours once you include the conversation at the start, the build, the content, and the fixing afterwards. That's where £1,000 to £1,250 comes from. One designer put his standard rate at "£1000 which includes pages, basic seo and other generic demands". Another said he could "set up a site for under £500 and still make decent profit". A third, quoting for a custom-built theme, said "Last time I built a custom theme my fee was nearly £5k". All three are describing real work. They're describing different amounts of it. Why the quotes you get vary so much Three things move the number more than anything else: whether the design is custom or a template, whether you're writing the content or the agency is, and whether anything needs to be built rather than configured - a booking system, a payment flow, a members' area. A £400 quote and a £4,000 quote are usually not the same job. Ask each one what's actually included rather than comparing the totals. The cheap end, honestly You can get a site built for £200 on a freelance marketplace, and some of those are fine. The risk is in what happens next. One UK business owner described paying for a redesign through a freelancer and then "the website went down". Another found the designer had registered the domain in his own name. If you go that route, get the domain in your name first and keep your own logins. The ongoing costs nobody mentions in the quote The build is one number. Running it is another. UK rates posted by agencies in late 2024 put WordPress maintenance from around £100 a month, SEO from £300, and paid ads management from £400. Hosting and a domain are small by comparison - tens of pounds a year, not hundreds. Ask for the monthly figure at the same time as the build figure. A cheap build with an expensive tie-in is a common shape, and it's the one people regret. What to ask before you pay a deposit Who will own the domain. What happens if you want to leave. Whether you can edit the text yourself afterwards. Whether the quote is fixed or an estimate. Get the answers in writing - a real quote should survive being printed out.

Meta Ads, Shopify and Google Analytics 4 can all show different sales figures because they measure different things and use different attribution methods. Shopify records the orders that actually happened in your store. Meta tries to determine which sales were influenced by your Facebook and Instagram ads, while GA4 attributes purchases according to its own tracking and attribution rules.
