Custom Programming for Your Zen Cart®

Please Note: I've checked my site for HeartBleed Bug vulnerabilities and found that my hosting uses the OpenSSL 0.9.8 branch, which is not vulnerable.

Welcome to Vinos de Frutas Tropicales, where I specialize in Zen Cart customizations. My name is Cindy Merkin and I've been developing software and software systems for 37 years — Zen Cart for the past 5 — and am an avid problem-solver. Let me help you to get the most out of your Zen Cart!

I can help you install a new or upgrade an existing Zen Cart. If your site needs something special, I can provide you with some custom programming to implement your vision. When your site's not working properly, I can diagnose and correct the problem. It all starts with a quote; let me know your website's name and give me some details about the job you'd like quoted and I'll get right back with you.

I've also got a variety of Zen Cart Plugins that I've either authored or contributed to available for download at Vinos de Frutas Tropicales. The majority of them are available for free download and, for a small fee, I can install them for you.

You might be wondering what this website's name has to do with Zen Cart customizations — short answer: nothing. My husband, Stan, and I have a corporation in Costa Rica named Vinos de Frutas Tropicales S.A., so we registered this website name. The website's here … I figured I might as well use it.

I'd like to announce the availability of v1.2.0 of the Payable Invoice payment method! This payment method allows you to truly invoice your customers; the customer comes back to your store to pay their invoice using one of your other payment methods (e.g. PayPal,, LinkPoint API, and others). Both the invoice and the final payment occur on the same Zen Cart order_id, making it easy for you to manage your invoices and their payments!

In addition, v1.3.1 of the Automated Email Engine (AEE), is now available — a Zen Cart plugin that allows you to easily configure and automate after-purchase emails sent by your store. You configure the AEE to send emails a specified number of days after an order's orders-status value is changed to a specified status. Check out the readme.html file, available via the plugin's link, for more information.
