Price input helper is an admin tool that allows to quicly enter price in many situations where calculator would be needed.
Special price input field is added on product edit page where alternate price can be entered. Product price gets utomatically calculated based on the multiplyer you define. The operation can be performed also the other way around - enter product price and the helper will show you the modified price. This works for all price entries.

Current version: 1.0 with introductory price

Tested on Opencart,, unchanged admin template. Should work on other 1.5.x versions. Feed back welcome.

Longer Description

Initially it was designed for the store owners who new what their product price has to be after taxes applied. The issue for them was to manually calculate the price without tax every time (that is how Opencart works by default). If this is your situation, then this module is definately for you. You will not waste your time anymore for calculating the right price on the calculator.

This modification adds a helper field next to the price field at all locations where the price input is available. You just enter the price which you want your customers see and the price field will be automatically updated according to the price modifyer (or multiplyer).

vQmod is required to run this module. Contact me if custom implementation is needed or you have modified product edit page template.


This cannot be easier:[*]backup store files (as you should do always)[*]upload all files from upload folder to your store root. Nothing is overwritten.[*]Install the module as usually from the Extensions-->Modules by installing Price input helper

If your admin panel is not in English and you want it in your native language, you need to copy and modify the module language file admin/language/english/module/price_input_helper.php and store in the respective language directories.


You can change the modifyer (or multiplyer) in the store administration under the module settings.Extensions-->Modules and edit Price input helper

You can use it during editing the product via the product form.
