Is Your Old Zen Cart Store
a Ticking Time Bomb?

Running Zen Cart 1.3.x or 1.5.x exposes your business to threats that could wipe you out overnight.

🔓

Critical Security Holes

Zen Cart 1.x no longer gets patches. Known exploits are actively targeting outdated stores to steal payment data and customer records.

🐌

Broken PHP 8.x Compatibility

Modern hosting runs PHP 8.x. Old Zen Cart throws fatal errors — causing white screens, checkout failures, and lost sales every day.

📉

Google Rankings Slipping

Google penalizes slow, insecure sites. Competitors on modern platforms are outranking you. Every week you wait costs real revenue.

💳

Payment Gateways Dropping

Stripe, PayPal, and Square are cutting off outdated platforms. You could lose the ability to take payments with zero warning.

Common Questions

Frequently Asked Questions

How long does a Zen Cart upgrade take?
+
Standard upgrades (1.5.x → 2.x) take 7–14 business days. Legacy 1.3.x upgrades typically take 14–21 days. You receive a specific timeline in your scoped proposal before any work begins.
Will my store go offline during the upgrade?
+
No. The entire upgrade is done on a staging server — your live store keeps running normally. The final go-live takes 15–30 minutes and is scheduled during your lowest traffic window.
What happens to my custom plugins?
+
Every plugin is audited in your free assessment. We check each against Zen Cart 2.x compatibility. Where compatible versions exist we migrate them; where they don't, we rebuild or source an alternative — always with your approval.
Can you upgrade from a very old version like 1.3.7?
+
Yes, and we do it regularly. We've successfully migrated stores from as far back as Zen Cart 1.2.x. Legacy upgrades require careful data mapping and custom code handling — our team has done hundreds safely.
Will my Google rankings be affected?
+
We protect your SEO during every upgrade — preserving URL structure, implementing 301 redirects, migrating meta data, and submitting updated sitemaps. Most clients see ranking improvements after upgrade due to better performance scores.
What if something breaks after launch?
+
All packages include post-launch support (14–90 days depending on tier). Any issues directly related to the upgrade are fixed at no extra charge. We don't consider a project complete until your store runs perfectly in production.
Why does the $349 plan exist — isn't a Zen Cart upgrade always complex?
+
Not always. Simple stores on 1.5.x with a standard template and a handful of plugins can be upgraded cleanly and efficiently. The $349 Standard plan is sized for those stores. If your store is more complex, the Advanced ($699) or Enterprise ($1,299) plan covers everything. The free audit confirms exactly which applies to you.
