Standard Salesforce rollup summary fields only work on master-detail relationships. For admins who need rollups on lookup relationships, relative date filters, or formula-based rollup logic, the standard toolset falls short – and the paid alternatives add meaningful cost to an org that’s already expensive.
Declarative Lookup Rollup Summaries (DLRS) is a free, open-source tool that closes those gaps. Rollups across lookup relationships, relative date filters like ‘sum of sales in the last 365 days’, and formula fields in rollup logic – all without Apex code and without a paywall. It’s been around long enough to be stable and well-documented.
For Salesforce admins and consultants who are currently limiting their rollup architecture to master-detail relationships or paying for a third-party tool, DLRS is worth knowing about. The setup is straightforward and the capability it adds to a standard org is genuinely useful.
