What a system integrator does
A client hires an SI to deliver a project: replacing a billing system, connecting a new CRM to an ERP, or moving data between platforms. The SI designs the solution, chooses or recommends the software, configures it and builds the integrations. It is often still involved after go-live, running support or further phases.
Because the SI is there before the software is chosen, it shapes the shortlist. A vendor whose product the SI knows well, and whose consultants are certified on it, is more likely to be recommended.
How SI partnerships work
A vendor and an SI usually agree to train the SI's consultants, give them sandbox access, and work deals together. The SI brings the vendor into projects where its product fits, and the vendor brings the SI into deals where the customer needs implementation help. That two-way flow is a form of co-selling.
Revenue credit depends on the deal. If the SI found the opportunity and registered it, it is often partner-sourced. If the vendor found it and the SI helped close it, it is partner-influenced revenue. Many vendors also track how many of an SI's consultants hold a partner certification, since that predicts the quality of deployments.
Why SIs matter
Enterprise buyers often will not buy software without someone to implement it. An SI removes that blocker and lowers the risk of a failed rollout, which protects renewals.
Example
Cobalt Consulting, an SI, is hired by Lumen Health to replace its patient billing workflow. Cobalt's architects recommend a SaaS billing vendor they are certified on and register the deal with the vendor on April 8, estimating a $60,000 annual contract.
The vendor approves the registration, and its account executive joins Cobalt for the final presentation. Lumen signs in June. Cobalt bills Lumen $45,000 for implementation, and under the vendor's SI program it also earns a 10% referral fee on first-year subscription revenue: $6,000.
