WayForPay for Shopify Checkout is a native integration of WayForPay via Shopify Payment Apps API. The only gateway offering installment payments from monobank and PrivatBank directly in the standard Shopify Checkout.
Why WayForPay is a separate story in Ukrainian Shopify
If plata by mono wins by rate (1.3% — the lowest in Ukraine), and LiqPay wins Privat24 and brand age, then WayForPay wins by the product matrix of payment methods. This is not a payment gateway of a single bank. It is an aggregator that gathered what the Ukrainian market really uses: classic cards, Apple Pay, Google Pay, Privat24, and — most importantly — both major installment payment schemes at once.
Installment Purchase from monobank and Installment Payment from PrivatBank are not marketing options. For many categories (electronics, home appliances, furniture, children’s products, cycling, jewelry) this is 30–60% of all sales. If your checkout does not support installment payments — you lose not a small share of turnover, you lose half the market.
WayForPay for Shopify Checkout is the third way. Native. Which did not exist before this year. — and it works within Shopify’s rules
Until recently, there were only two ways for a Shopify store to accept installment payments: on the thank you page (with pending orders and manual moderation) or through a third-party checkout, where Shopify Checkout was completely replaced by a custom one — which directly violated the platform’s rules. More about the legal side in the article about third-party checkout solutions.
02 — through the buyer’s eyesWhat exactly the buyer sees on Shopify Checkout
This is the most critical part for conversion. Ukrainian buyers are used to seeing the full list of payment methods on one screen. If even one is missing, some customers close the tab and go to a competitor.
★ — methods not available in plata by mono Checkout or LiqPay Checkout. WayForPay offers both BNPL programs simultaneously — a unique position in the Ukrainian market.
03 — BNPL economicsHow much you lose each month without installment payments
This is not a rhetorical question. The calculator below calculates lost turnover by three parameters: current turnover, average check, and the share of categories where installments cover a significant part of sales.
bnpl-effect calculator
The calculation is based on real statistics from stores with an average check of 5,000+ ₴. Connecting Purchase in Installments + Payment in Installments gives a turnover increase of +30–50% due to purchases that previously failed at the checkout stage. The calculator uses a conservative assumption: 70% of the theoretically lost volume returns.
WayForPay Checkout economics: honest arithmetic
WayForPay historically has a higher base rate than monobank — and this is normal for an aggregator. You pay 0.7 percentage points above monobank acquiring for the ability to have the entire BNPL and Privat24 product matrix under one API.
About the commission for installment payment schemes
This is an important point that confuses many. The commission for installments is not WayForPay acquiring. It is a separate fee that the bank (monobank or PrivatBank) charges for providing the credit program to the buyer. Usually, it is 4–7% of the order amount once, depending on the number of payments and the program. The bank charges this commission to the store; the buyer pays only the nominal amount.
It sounds expensive until you calculate in the calculator above how many orders you actually lose without installments.

What works "under the hood"
WayForPay Checkout uses WayForPay Merchant API through Shopify Payment Apps API. No magic — standard server-to-server flow, like Stripe or Adyen.
5 steps from Shopify to payment confirmation
No "own" web forms. No saved CVV. No PCI scope on the store side — all PCI-DSS remains with WayForPay (as it should be).
08 — objectionsCommon objections and honest answers
“WayForPay’s fee is 2%, and monobank’s is 1.3%. Why pay more?”
“What if I only need Privat24, without installments — is it easier to use LiqPay?”
“Can I connect WayForPay Checkout and LiqPay Checkout simultaneously?”
“I already have a separate monobank Installments app on the Thank You Page. If I connect WayForPay Checkout — do I still need it?”
What the transition from Wallnut/Chekly looks like in 7 days
Store downtime — 0 minutes. The old checkout is disabled only after the new one is confirmed launched. Here’s how the transition happens day by day.
Application and audit
Getting access to the Shopify store (Collaborator account), checking the plan, current payment methods, FOP/LLC details. Opening a WayForPay account (if not yet opened) — takes 1 business day in parallel.
App installation and setup
Installing the Shopify Payment App, setting up WayForPay details, activating all methods (Visa/Mastercard, Apple Pay, Google Pay, Privat24, both installment programs). Creating webhook endpoints for callbacks.
Test mode
Running real test orders (with your card, for a small amount), checking callbacks, refunds, orders with Paid status in the admin panel. Simultaneously setting up fiscalization through Vchasno.Kasa or Checkbox PRRO.
Switch + the old system still works
We activate WayForPay Checkout as the main payment method. The old Wallnut/Chekly remains in place as a backup for 1 day — for confidence. All new orders go through the native Shopify Checkout.
Disabling the old checkout
After 1 day of successful operation, we disable the third-party checkout. The store is fully on Payment Apps API. We train the support team in a 30-minute call: where to check callback logs, how to do refunds, how to read the BNPL orders report.
Support and optimization
We monitor the first week, on the 30th day — a report on BNPL conversion and turnover. If turnover grows by 200+ thousand ₴/month — we help switch WayForPay to an individual tariff (from 1.5%).
