Custom One‑Page Checkout for Shopify
A branded one-page checkout for Shopify stores serving Ukraine: local payments (Plata by Mono, LiqPay, WayForPay), Nova Poshta, cash on delivery, upsells and cross-sells. Fixed price $25/month, no revenue share. Goes live in 1 days — no Shopify Plus required.
What is a custom Shopify checkout?
A separate one-page checkout that replaces the standard Shopify flow. Buyers see a single page with shipping (Nova Poshta, Ukrposhta, courier), payment (LiqPay, Plata by Mono, WayForPay, cash on delivery) and fields styled in your brand. Unlike off-the-shelf apps like Chekly or Checkify, our checkout is custom-built for your store: a flat fee with no revenue share, full design freedom and an open-ended integration set. Shopify Plus is not required — the solution works on Basic, Shopify and Advanced plans.
Why standard checkout often underperforms
A custom checkout helps remove friction and improve completion rate.
01 — Lower conversion
Multi-step flows and unfamiliar UX increase abandonment.
02 — Missing local shipping
Local carriers often require custom integrations.
03 — Limited local payments
Popular payment methods may not be available out of the box.
04 — No upsells
You can’t easily add upsells/cross-sells inside a standard flow.
05 — Not fully branded
A fully branded experience is hard to achieve with default settings.

What clients say about our custom checkout
4.9 / 5 · 24 reviews
"Before the custom checkout our conversion sat around 1.3%. After switching to the Zelvix one-page checkout with Nova Poshta and LiqPay we’re consistently at 2.1–2.3%. It paid for itself within a week. The team shipped it in 5 days and helped wire up Facebook Pixel."
"We tried Chekly — nice UI, but no LiqPay and a revenue share on top. With our monthly volume that share alone was ~$170/month just for a form. Zelvix built our own checkout with all our payment methods and Apple Pay. We pay a flat $25/month and got upsells on top."
"We needed partial prepayment + cash on delivery + LiqPay in a single checkout. Impossible with stock Shopify. Zelvix built a custom checkout that has been running error-free for 4 months. Abandonment dropped by half."
"We’re on Shopify Basic and didn’t want to jump to Plus just to customize checkout. Zelvix offered a dedicated checkout page — fully on-brand, with subscriptions and Nova Poshta delivery. Live in 4 days, conversion went from 1.8% to 2.7%."
"Support is what stood out — I ping them on Telegram and get an answer the same day. They’ve helped multiple times with GTM on the checkout page. Unlike Chekly, you’re talking to an actual human, not a ticket queue."
"There were a few small rendering quirks on iOS the first weeks — fixed quickly. Everything runs smoothly now and conversion is up. I really like that we can edit checkout copy and field order on our own."

FAQ about the custom Shopify checkout
How does this differ from Chekly or Checkify?
Chekly and Checkify are off-the-shelf App Store apps that improve the checkout form. They charge a monthly fee plus a revenue share (typically 0.5–1%), are template-based, and don’t natively support every Ukrainian payment or shipping method. Our custom checkout is built specifically for your store: a flat $25/month with no revenue share, full design freedom, and any integration you need. For most Shopify stores serving Ukraine with $3k+/month in revenue, custom is cheaper even short-term.
Do I need Shopify Plus for a custom checkout?
No. Our custom checkout works on Basic, Shopify and Advanced plans. We deliver it as a dedicated checkout page on a subdomain of your store. This makes it accessible to most growing stores — Shopify Plus at $2,300/mo is not required.
Which payment methods can you connect?
Plata by Mono, LiqPay (PrivatBank), WayForPay, RozetkaPay, Fondy, Stripe, Nova Poshta and Ukrposhta cash on delivery, bank transfer, partial prepayment, Apple Pay, Google Pay, Privat24. You can offer several gateways at once — the customer picks what they prefer.
Does conversion drop because the checkout is on a subdomain?
No. Modern browsers and payment processors handle a subdomain identically to the main domain when SSL and redirects are configured correctly. We use checkout.yourstore.com, which actually increases the perceived security. We’ve seen no conversion drop attributable to the subdomain across our clients.
Can I run upsells inside checkout?
Yes. The custom checkout supports upsells (higher-tier offers), cross-sells (related products), bundles, free shipping thresholds, urgency timers, and social proof messages (e.g. "23 people bought this today"). Everything is A/B testable.
How fast can the custom checkout go live?
Typically 1 business days from brief to launch. Heavier scopes (e.g. custom logistics or recurring billing) take 10–14 days. During development your store keeps taking orders via standard Shopify Checkout.
What’s the pricing — and is there any revenue share?
Flat $25/month. No revenue share, no hidden fees. Support, updates, and adding new payment/shipping integrations are included. Larger one-off projects (e.g. new CRM integrations) are billed hourly.
Will it work with KeyCRM, Bitrix24 and other CRMs?
Yes. The custom checkout writes orders to Shopify Admin as normal Shopify orders. All your existing CRM and logistics integrations (KeyCRM, Bitrix24, Torgsoft, Nova Poshta API) continue to function untouched.
Can I set up Facebook Pixel, Google Analytics and GTM?
Yes. We install Facebook Pixel, Google Analytics 4, GTM, TikTok Pixel and other tags directly on the checkout page. This gives you precise conversion attribution — something standard Shopify Checkout limits without Plus.
Will it impact my store’s SEO?
No. The custom checkout is a transactional page with noindex — it isn’t indexed by search engines. Your product, collection and content pages keep their SEO.
What happens to orders if the checkout has an outage?
We ship a fallback: if the custom checkout becomes unavailable, customers are redirected to the standard Shopify Checkout. We also monitor availability 24/7 and notify you about incidents. Over the last 2+ years no client has experienced more than 10 minutes of downtime.
