Can You Stack Them?
Yes. CDAP focuses on adopting commercial technologies (e.g. installing CRM, ERP, or cloud commerce infrastructure), whereas SR&ED is for developing custom technology. You can claim CDAP for adoption tooling and SR&ED for core custom software development without any overlapping conflict.
The Expert Verdict
If you are an established business upgrading your internal systems or digitizing operations, apply for CDAP immediately. If you are writing custom software or engineering custom products, file for SR&ED.
