6 critical control questions about the checkout (Checkout Friction Points)
PUSH E-COMMERCE ENGINEERING
Why do the cart and checkout account for 45% of the total revenue leak?

The checkout is the zone of the final financial decision. The customer has been through the entire marketing journey and has picked the product. Dropping out at this stage means losing an almost certain profit. In the PUSH engineering model as much as 45% of the margin leak falls on checkout friction: forced registration, no instant BLIK, a lagging parcel-locker map or an overloaded form. The 6 questions below help diagnose the bottlenecks and calculate the amount of profit leaking away.

1
Can a customer buy as a guest (Guest Checkout) without having to create a password?
UX principle Zero entry barriers: The customer is buying a product, not a legal relationship with the store. Guest checkout must be the default option, and the password prompt should appear only after the order is paid for.
Why this decides profit According to the Baymard Institute, forced registration is the number 1 reason for cart abandonment in e-commerce (26–28% of customers drop out the moment they see a password requirement).
How to check it in 10 seconds Open your store in incognito mode, add a product and go to the checkout. Can you type an email and address straight away, or does the store demand a login or a made-up password?
2
Which payment methods do you offer, and can the customer pay without leaving the checkout interface?
UX principle Express finalisation: The BLIK code field and Apple/Google Pay wallets should sit directly in the form, eliminating redirects to the bank.
Why this decides profit In Poland BLIK drives over 70% of transactions. A redirect to an external gateway increases order drop-off by 8–15%. No deferred payments (PayPo/Klarna) cuts sales of carts above PLN 200 by 15–20%.
How to check it in 10 seconds Go to the payment step. Do you see BLIK tiles with a code field and Apple/Google Pay on the page, or does a click redirect you to an external operator site?
3
How does choosing an InPost parcel locker work on a smartphone (geolocation, search, map)?
UX principle Fast pick-up point selection: A smartphone needs automatic GPS geolocation, search by postcode/street and remembering the favourite locker.
Why this decides profit Over 80% of buyers in Poland choose parcel lockers. A heavy, stuttering map on the phone accounts for 12–18% of checkout abandonments on mobile devices.
How to check it in 10 seconds Open the checkout on your phone and pick a parcel locker. Does the system suggest the 3 nearest lockers in 2 seconds, or open a map that freezes the browser?
4
How long is the address form, and does it use automation (Autofill, GUS lookup by VAT ID)?
UX principle Minimal fields and zero needless typing: Browser autofill, address suggestions and pulling company data from GUS once the VAT ID is entered.
Why this decides profit Every redundant field lowers conversion by 3–5%. In B2B, no GUS registry integration forces the procurement buyer to retype data by hand, which breeds frustration.
How to check it in 10 seconds Tap the address field on your phone — does the browser fill the data in one click? Enter a VAT ID: do the company name and address fill themselves in a fraction of a second?
5
Is the order summary transparent and permanently visible while the details are filled in?
UX principle Financial transparency and a steady state: Zero price surprises at the finish, an exact delivery day and a sticky cart summary.
Why this decides profit Adding a payment or packaging fee on the last screen makes 48% of buyers abandon the checkout instantly. Customers feel manipulated.
How to check it in 10 seconds Does the final amount match the cart to the last grosz, does the delivery date point to a specific day, and does the summary with thumbnails follow the scroll?
6
Does the store react in real time when the customer tries to leave the checkout (Exit-Intent and Local Storage)?
UX principle Rescuing purchase intent: Reacting to the cursor leaving the checkout window on desktop and saving the cart automatically in browser storage.
Why this decides profit As many as 70% of users hesitate before clicking “Buy”. A smart exit-intent (advisor support, return guarantee, rescue discount) recovers 5–14% of transactions.
How to check it in 10 seconds With the checkout open on desktop, move the cursor sharply towards the browser tab close button. Does the store try to keep the session, or let you close the page without a word?

    Cart and checkout audit (Checkout Friction Index) — why does the checkout account for 45% of the revenue leak?

    The cart and the checkout form are the decisive moment of the entire e-commerce journey. This is where the most painful margin loss happens: the customer has reviewed the offer, accepted the price, added the product to the cart and expressed an unequivocal purchase intent. If they leave the store at this point, the cause is almost never the product itself, but process, ergonomic and technology friction.

    The engineers of PUSH — e-commerce engineering and conversion optimisation (10+ years of experience, Rolexpress and Bonmario case studies) built Checkout Friction Index — a tool that diagnoses the critical barriers in One-Step, Multi-Step and B2B checkouts. Per the PUSH model the cart and checkout account for as much as 45% of the total margin leak in an online store.

    Guest checkout A mandatory account is the number 1 reason for cart abandonment worldwide (26–28% of drop-offs per Baymard). Guest checkout by default removes the entry barrier and lifts order completion.
    Instant payments in the checkout BLIK directly in the form, Apple Pay, Google Pay and deferred payments (PayPo/Klarna) cut the transaction time to a few seconds and eliminate drop-off after a bank redirect.
    Logistics and ergonomics on smartphones InPost parcel lockers are the choice of over 80% of buyers in Poland. Replacing a heavy map with GPS geolocation and postcode search saves 12–18% of mobile transactions.

    How do we calculate the revenue leak in the checkout? (PUSH Engineering Model)

    The cart and checkout account for 45% of the e-commerce revenue leak — this is where you lose margin on traffic you already paid for in Google Ads and Meta Ads

    Most online stores lose between 65% and as much as 75% of the customers who entered the checkout. Lifting checkout conversion from 25% to 35% means an immediate jump in net profit of tens of percent — without increasing ad spend.

    Registration and form barriers A password requirement, a duplicated email, artificial field splitting or no company-data lookup from the GUS registry in B2B wholesale transactions.
    Payment-method friction No BLIK code directly in the checkout, no mobile wallets and no deferred payments on orders above PLN 200.
    Price surprises at the finish Payment or packaging fees added on the last screen, no clear delivery date and no cart-recovery mechanism (exit-intent).

    Frequently asked questions about checkout audits and optimisation (FAQ)

    Checkout Friction Score is a points score (0–100%) that diagnoses the level of process and technology barriers at the order finalisation stage. The cart and checkout account for as much as 45% of the total margin leak in a store, because this is where users with the highest purchase intent arrive. If a customer drops out because of a mandatory account, a missing BLIK or a stuttering map, the store loses the margin for good, along with the entire budget spent on acquiring that user in ad campaigns.

    According to global Baymard Institute research, forced registration makes over 26% of customers abandon the cart immediately. Buyers see a password requirement as a waste of time and an unnecessary intrusion into privacy, especially on a smartphone screen. A benchmark checkout sets guest checkout as the default option and offers account creation (saving the password in 1 click) only on the order thank-you page.

    There is no single universal answer — effectiveness depends on the data architecture. A one-step checkout works perfectly in simple retail (B2C), provided the form is short and does not overwhelm the user with a flood of fields. A multi-step checkout (with a clear 1-2-3 progress bar), in turn, works brilliantly for higher-priced products, made-to-order configurators and B2B, where the customer verifies the specification, address and commercial terms step by step.

    InPost parcel lockers are the most popular delivery method in Poland (over 80% share). However, standard map widgets can be very heavy: they load hundreds of points at once, block smooth page scrolling on a phone and cover the order-finalisation button. The most effective solution is automatic GPS geolocation suggesting the 3 nearest lockers, a quick search by postcode and remembering the favourite locker for returning customers.

    In B2B the business buyer's time and fiscal data automation are critical. A B2B checkout must integrate the REGON / GUS registry — after entering the 10-digit VAT ID the company name and registered address must be pulled automatically. It also needs: deferred payment terms (14/30-day transfers for regular partners), a purchase order reference (PO number) and the ability to set a different delivery address for a construction site or a warehouse.

    The PUSH audit is based on hard data and systems engineering. We analyse GA4 event funnels (begin_checkout → add_shipping_info → add_payment_info → purchase), user session recordings in Hotjar/Clarity and JavaScript console errors during form validation. We prepare a UX mock-up of the optimised checkout flow plus production-ready code for WooCommerce, PrestaShop, Magento 2 or Shopify. A free consultation can be booked on 721 725 577.
