I hope I'm in the right subforum for this. My question probably describes a relatively unusual situation, and is likely not in the typical eCommerce realm, but any tips anyone could provide would be greatly appreciated. I'm not really sure this is even truly an ecommerce issue, as we're primarily looking for a catalog with inventory management and display functions, including the ability to embed products in our pages, but otherwise completely bypassing any cart or checkout system in favor of passing custom URLs with parameters to our existing form system. My organization has an existing site with a flexible form and payment system integrated into a master database from which we query and utilize data for everything from email marketing to reporting and accounting and all other online efforts. We do have an ecommerce system aboard, but it will not fit our needs for this project, and it cannot be customized appropriately. Essentially, we need only the catalog portion of an ecommerce system - no checkout, no cart for multiple item purchases, in fact we can only sell one item at a time for this project - that permits at least rudimentary inventory management for single-sale items (unique items that, once sold, are no longer available - quantity 1 in all cases), but which allows us to pass the product information through to our form system for checkout. The process would be: Catalog items are populated into display page or pages, preferably with an option to randomly display a different set of perhaps a dozen items on each page load. Preferably an option to display a larger image of the item on click-through. Selection of an item for purchase does not add the item to a cart. Each item's "buy" button link can be either programmatically or manually pointed to our cart system and set with URL parameters which would pass the item's unique identifier and other information to custom fields on our form. Preferably the form would be able to retrieve the item information from the catalog as well to display on the form as a visual indicator of the item selected. The form would be processed entirely on our end. Once the form processed successfully, it would call back to the catalog to instruct it to remove the item from inventory, similar to the manner in which our conversion scripts for Google Adwords, Google Analytics, Clicky and others operate. I could swear that I have seen a script/system like this a few years ago, but I cannot locate it again. We could write our own, but we are very thin on resources, and if we can find something close and modify it as needed we would be far better off. We are a non-profit organization, and as such are caught between a lack of resources (particularly time) and an extremely limited budget. Any tips on potential scripts/systems that might fit the bill here would be appreciated, if such exists. In many respects, a gallery script for images and image descriptions would actually almost do the trick here, save for the need to maintain an inventory of 1 unit per product and the ability of non-technical staff to manage that inventory. Thank you.
