Built for different desks
Brindle is built for ANZ recruitment agencies that place at volume, and it fits temp, labour hire, and contract desks best. The others were built for a different buyer, corporate HR, enterprise compliance, and one-off permanent hires, and adapted from there.
None of them is wrong. A corporate HR team running five permanent hires a quarter has different needs from an agency running 30 placements a week. Per-check pricing works for the first. It breaks the second.
