STACK is a cloud-based construction software designed to streamline the estimation process for small contractors, particularly those managing complex projects. Its standout feature is the high level of customization it offers, making it perfect for contractors who need to tailor their estimates and proposals according to various project requirements.

Comprehensive Measurement Tools: STACK provides dedicated tools for measuring different project components, including area, length, arc, pitched, volume, and counts. This makes it highly versatile and capable of handling a wide range of construction tasks, from residential to commercial projects​

Customizable Templates and Libraries: With STACK, contractors can access a vast library of pre-built templates and items for materials, assemblies, and other project needs. Users can also create custom templates, which can be reused across different projects, making it easier to standardize proposals and save time​.

Centralized Hub for Project Management: STACK goes beyond basic estimating by offering a centralized hub for managing, tracking, and communicating with stakeholders. It makes collaboration easy by centralizing all project information in one location, improving workflow and reducing miscommunication

Cons: Some users have reported that the software can become slow when working with large data sets, which may be a consideration for those handling more complex or larger-scale projects​
