7 days to migrate, optimize, and protect
Shopify doesn't send lost revenue alerts. You only find out when sales drop — and by then, the damage is already done.
If you used Shopify Scripts to stack promotions or calculate dynamic shipping, those flows stopped on June 30. Customers reach checkout with a promised discount and leave without it. That's not friction — it's guaranteed abandonment.
Additional Scripts on the Thank You and Order Status pages stop working in August. Your Meta Pixel, Google Ads, and conversion analytics will stop registering sales. You'll keep investing in ads without knowing what works.
All cross-sell logic built on checkout.liquid stops working. A customer buying a saxophone no longer gets suggestions for a case, reeds, and a stand. Every lost sale is revenue that will never show up on your statement.
The Guard isn't just a compliance migration. It's the moment your checkout stops leaking revenue and starts generating more.
All discount, shipping, and checkout customization logic is rebuilt in Shopify's new Extensibility architecture. No performance loss. No broken flows. No post-deploy surprises. Your checkout comes out more robust than before.
We rebuild the accessory cross-sell logic natively in the new framework. A customer renting a saxophone automatically sees reeds, a case, and a stand at checkout — customized for that instrument. Higher average order value (AOV), with no additional acquisition cost.
PageSpeed and Core Web Vitals are recorded before and after. Any degradation we cause is our responsibility to fix, at no additional cost. You receive the delivery with metrics in hand — not just a verbal promise.
Beyond the migration, we install an accessory cross-sell engine straight into the checkout. When a customer adds an instrument to their cart, the system automatically injects high-margin accessories for that specific product — customized by SKU, not generic rules.
Saxophone → reeds, mouthpiece, case
Every instrument category has its own mapped accessory set.
Guitar → strap, picks, cable
High-margin accessories appear at the exact moment of highest purchase intent.
AOV measured before and after
The impact on Average Order Value is tracked against the pre-migration baseline. You see the numbers.
The business logic: a customer who arrived to buy already has peak intent. Showing the right accessory at the right checkout is the most cost-effective form of revenue that exists — no campaigns, no acquisition costs, no additional margin overhead.

Metrics documented upon delivery. Maintained by the Revenue Retainer.
Every new app you install — Klaviyo, Recharge, Meta Pixel — can silently degrade what we delivered. Without monitoring, the conversion you recovered starts draining back out without warning. The B4 Revenue Retainer is the layer that keeps the Guard working exactly as delivered.
Guard + 3-month minimum protection
Every app update or platform change is checked before it affects your conversion. You won't be caught off-guard when the problem is already massive.
The delivered PageSpeed and Core Web Vitals remain covered during the Retainer. Any degradation caused by our work is our responsibility to fix.
The CRO accessory engine is monitored month by month. You track the impact on your average order value and receive fine-tuned mapping adjustments when the data indicates an opportunity.
If you want to understand the complete landscape before deciding — the actual impact of deprecations on your store, where conversion is leaking, and what's worth prioritizing — the Storefront Audit answers that in 5 business days.
