Understanding the full commercial opportunity in the Oasis by Paychex installed base.
The total addressable market for vendors targeting Oasis by Paychex users is defined by the 13,284+ confirmed companies currently running Oasis by Paychex worldwide. This installed base represents the universe of organisations that have already invested in the PEO & EOR Services category — meaning they have validated budget, a procurement process, and active technology decision-makers in place. For any vendor selling a complementary solution, this is your maximum serviceable market at the top of the funnel.
Within the 13,284+ total companies, the realistic serviceable addressable market (SAM) narrows based on your product fit, target company size, and geographic focus. For example, an enterprise software vendor targeting companies with 1,000+ employees operating in financial services would find approximately 32% of the list — or 4,251+ companies representing their highest-priority accounts. The ability to slice the Oasis by Paychex list by industry vertical, company size band, revenue range, and geography is what converts a broad TAM into an actionable pipeline.
Decision-maker density is a critical TAM multiplier. Most of the 13,284+ Oasis by Paychex companies have multiple relevant contacts — the average enterprise has between 3 and 7 decision-makers involved in a technology purchase. ELP Data maps all relevant titles at each account: CHRO, VP People, HR Director, CFO and more. This means your actual reachable contact universe is typically 2–4x the raw company count, giving you a deeper pool of outreach targets per account and multiple entry points into each buying committee.
