Slabstack
Slabstack is a CRM and sales intelligence platform for ready-mix concrete, aggregate, and asphalt producers. It centralizes customer and dynamic pricing data to populate quoting templates, combining material and hauling prices for quotes. Its dispatch integrations connect sales and dispatch data, and Slabstack says integrations with Command Alkon and Sysdyne support two-way data flow. Forecasting and business intelligence tools track sales, pricing, and margin trends across representatives, locations, and customers. The Backlog view combines quote, forecast, and production data to show performance, risk, and revenue in real time. Slabstack lists Command Alkon, Sysdyne Technologies, and Apex among its integrations or partners; its aggregate solution also describes a two-way connection with Command Alkon and Apex. Built-in metric pricing and quoting is available to producers in Canada, the UK, Australia, and New Zealand. The platform is listed for web, Android, and iOS and includes bid management and dispatch scheduling. A press release describes a sales-team mobile app as coming soon in app stores. Pricing is available on request, with no amount or plan limits stated. Sysdyne Technologies acquired Slabstack in December 2025.
