Small to Medium Business (SMB) Accounting Software

The SMB market·typically serves businesses with 5-25 active users, while the Mid-Market can serve from 25-100 active users. High Mid-Market candidates have more demanding transaction and reporting needs and therefore scale very well. These solutions typically support more functionality and a broader range of reporting. The underlying database is more robust, and therefore, SMB products are more scalable and able to take the business to its next level. Where only a few years ago the SMB and Mid-Market had very different competitors, over past few years SMB vendors have enhanced their database capabilities and added features and functions that were only found in much larger applications before. Today, you can feel comfortable selecting a product as a small business that will scale with you easily as you grow.

Enterprise Accounting Software

Enterprise solutions typically target large organizations of 100 users or more. The feature set and functionality of these systems is advanced and very robust, so specialized businesses of as few as five users, such a process based manufacturing or large scale project management, could benefit from these applications. We do not cover the highest end Fortune 1000 company solutions here because there are few options.

Today there are perhaps three primary contenders, SAP, Oracle and Lawson (infor), at the very high-end Enterprise Resource Planning (ERP) level. However, other products such asSage ERP X3 and Microsoft Axapta are strong contenders at much lower total cost of ownership. Businesses that once believed they had limited choices are finding other options work very well at the high-end and that the choice of only selecting a high-end ERP solution is no longer true.

Business Analytics – Business Intelligence & Reporting Software

Business Analytics and Reporting are extremely important in any business. Many software manufacturers offer specific products to accomplish this, as well as products that are independent of specific accounting applications. The list below represents a short list of the top solutions in this classification.

Customer Relationship Management (CRM) Software

Customer Relationship Management (CRM) and contact management tools allow teams to track customer interaction, monitor employee activity, and generate routine correspondence to customers.
