Something on your store is silently costing you sales.
Sales tracking, discount rules, and connections to other systems break without warning on customised Shopify stores. We scan yours from the outside, with no store access and nothing to install, and send a report with proof.

Keep it monitoredYour ads may be flying blind
Stores that advertise have small pieces of code that report every sale back to Google and Meta. That is how you know your ads work.
On customized stores, this code breaks without warning. App changes, theme updates, and Shopify platform changes can each kill it. The store keeps selling. The ad platforms just stop seeing it. You watch your ad results collapse and blame the ads.
The latest wave: Shopify replaced checkout pages on August 26, 2026. On many stores, the old tracking code stopped firing that day. Google's free tools fix simple setups. They do not cover tag managers, affiliate tags, or custom code.
What we doWe find the dead code, rebuild your tracking the modern way, and add a backup that reports every sale straight from the server, so it works even when browsers block tracking. Then we prove it with a test order and show you the before and after.

Check my tracking freeAre your discounts still working at checkout?
Bigger Shopify stores often run custom rules at checkout. Wholesale prices for certain buyers. Free shipping over a set amount. Tiered discounts.
Shopify shut down the old system for these rules on June 30, 2026. On affected stores, the rules just vanished. No error message. Customers get charged full price and walk away, or discounts you retired come back. Margins drift and nobody connects it to the platform change.
What we doWe test your store with real carts and show you exactly which rules still work and which died, with screenshots of your own checkout totals. Then we rebuild the rules that matter on Shopify's current system and test them against real scenarios before your next promotion.

Test my discounts freeDo your systems agree with each other?
Growing stores have software bridges moving orders, inventory, and customer data between Shopify and other systems. The warehouse. Accounting. Email.
These bridges fail quietly. You find out weeks later, when something ships twice or the numbers do not add up at month-end. The person who built the bridge is often long gone.
What we doA one-week checkup. We compare your real order and inventory data across systems and measure exactly how much is drifting. You get a report showing every mismatch, what it costs, and what to fix first, walked through with you on a call. This one starts with a short conversation about your systems, since bridges cannot be seen from outside.

Ask about a checkupAPIs and platforms we have integrated
Stay or switch? Get a neutral answer on your subscription platform
If you sell subscriptions, your billing runs through a platform like Recharge or Skio. Those two merged in 2026, and thousands of owners now wonder whether to stay or move. Every vendor pitching you has the same answer: migrate to us.
A careless move can cost you 10 to 25 percent of your subscribers. We do not sell a platform, so our answer has no agenda.
What we doWe run your real order data through the actual fee math of your platform and the alternatives, map the risks, and give you one number: what staying costs versus what moving costs, with subscriber risk priced in. Delivered in a week, in writing, before your renewal locks you in. If moving wins and your setup is too complex for the platforms' free migration help, our team does that engineering at a fixed price.
Subscription platform decision
- $1,500 to $2,900, one week
- Complex migration engineering, only where the free vendor path does not apply: $8,000 to $15,000 fixed

Get a neutral answerWe can also keep watching
Most things we fix can break again, because Shopify changes its platform on a schedule and stores keep changing too. After a fix, many clients ask us to keep watching: their checkout rules, their tracking, their system bridges, checked continuously, with us finding problems before customers do. Monthly plans exist for exactly that. We will show you the one that fits at your delivery call, with your fix fee credited to the first month. No obligation, and no pressure before then.
The team behind the scan

Milos Vujnovic
CTO, OmniStreak
OmniStreak is a remote software engineering studio in Bratislava, Slovakia, run by CTO Milos Vujnovic. One of our clients is a DTC brand with 500,000 platform users, whose engineering we have run for 10 years, work recognized by INC Magazine. We work US East Coast and CET hours.
We migrated customers and orders from an old checkout platform, connected Shopify to the data pipelines that feed marketing and analytics, built subscription upgrade flows, and we run the server-side systems that report every sale to Meta even when browsers block tracking. Those systems process events for 500,000+ users today.
We have had the pleasure of working with the team at OmniStreak on several projects over the course of many years thanks to a word-of-mouth recommendation by a close partner. They are consistent, reliable, meet deadlines, and always deliver quality work.
Nathan JohnsonCEO, Maison Bloom
Where one takes orders, Milos and his team take charge. They apply a blend of business strategy and technical knowledge when approaching every project. The result was solution-based delivery that ultimately saved time and money.
Justin HedlundCEO, Hedlund Group
Their organizational skills combined with expansive technical knowledge made the process easy and effortless. The only regret I have is not choosing Milos' team from the beginning.

A person checks it. Not a crawler with a scorecard.
Automated tools tell you what changed. They cannot tell you whether it matters to your revenue. Every scan is read by a developer who has repaired the same breakages on customised stores.

Questions owners actually ask
Not for the scan. The free scan reads your store from the outside, like a customer's browser does. If you later hire us to fix something, you grant standard Shopify collaborator access, which you approve with a code and can revoke any time. It does not use one of your staff seats.
Then the report says your store is fine, and you have proof of that before your busiest season. The scan costs nothing either way. Some of the most useful reports we send are the clean ones.
A team of 20+ engineers in Bratislava, directed by CTO Milos Vujnovic. The same team that has run engineering for a 500,000+ user platform for 10 years.
Our costs are European, our clients are not. We also give the first three clients of each service 20 percent off in exchange for a public review and case study, because we are building our Shopify client list and honest proof is worth more to us than margin right now.
Fixes are built and tested on a copy of your theme or a test store first, then verified on your live store with a test order that we refund. The rescue services carry a fix-or-no-fee guarantee: if we cannot get it verified and working, you pay nothing.
