ITDevWorks is a development service provider focused on e-commerce sites and Authorize.Net integration. Its core products are IBillIt AIM/ARB and IBillIt CIM Library. The former is used for Authorize.Net AIM one-time charges and ARB recurring billing, while the latter wraps Customer Information Manager for storing customers’ credit card or bank account information on Authorize.Net’s secure servers, supporting repeat billing and reducing PCI-DSS compliance burden.
IBillIt AIM/ARB is built with C#/.NET Framework, but the page says it can be called from a range of Windows development environments, including C#, VB.NET, PHP, Java, C/C++, VBScript, JavaScript, VB6, and more. It also notes that since v1.1 it has been tested with Mono on Linux/Unix. Functionally, it supports custom data, MD5 hash validation, order line items, tax, shipping, duties, and other totals, and communicates with the payment gateway over SSL. CIM Library is a library for .NET managed code, positioned as easier to use than calling the CIM SOAP/XML API directly or relying on auto-generated proxies. It provides an object-oriented model, events, and multithreading options.
The page lists IBillIt AIM/ARB at $99. Pricing for CIM Library is not fully consistent: one section says $99 for early adopters, while another lists $199. Trial downloads are available for both products, and purchases include 30 days of free support. The site repeatedly highlights complete documentation, getting-started guides, reference docs, and sample code, but the crawled content also shows multiple “Page not found” entries, suggesting the site is not especially well maintained.
The main advantages are its clear focus on solving Authorize.Net AIM, ARB, and CIM integration problems; good fit for legacy .NET/Windows projects; relatively low one-time licensing cost; and availability of sample code. The downsides are that the product information is clearly dated, with copyright shown as 2008; there is no clear statement about open-source licensing or ongoing updates; it is tied to Authorize.Net, which limits its applicable market; and CIM Library pricing is inconsistent.
It is best suited to developers maintaining U.S.-market e-commerce sites, self-hosted shopping carts, or subscription billing systems, especially teams that already have an Authorize.Net merchant account and a .NET-based stack. Access from China, payment methods, and localized support are not described in the text, so these remain unknown. For China-focused businesses, Alipay and WeChat Pay would usually be higher-priority options; for international businesses, it is also worth comparing Authorize.Net’s official SDK, Stripe, PayPal/Braintree, or Adyen.
