Where they actually differ
An IDIQ is a contract under FAR Part 16 with a guaranteed minimum, a stated ceiling, and task or delivery orders issued under it, often used for services and multi-year programs. A BPA is a simplified acquisition or Schedule-based ordering agreement, typically for recurring commercial purchases, with lighter administration but no minimum guarantee obligation.
When Indefinite Delivery, Indefinite Quantity contract is the right choice
Pursue IDIQ vehicles when you want predictable, larger-dollar task order flow, are prepared to compete formally for award, and can support multi-year contract administration and reporting.
When Blanket Purchase Agreement is the right choice
Pursue BPAs when you sell commercial products or services against a GSA Schedule, want lower administrative overhead, and can compete well on fast, lower-dollar task calls issued frequently.

Most common under Schedules, though open-market BPAs exist under simplified acquisition procedures.
