Why these processors fit general contractors.

Stripe supports GC workflows where draws must match contract language—deposit, rough-in, dry-in, final—with descriptors owners recognize. Webhooks into accounting reduce ‘paid in QuickBooks but not in project software’ drift. Validate roles so assistants cannot issue refunds casually. Stripe fits when BD and project teams need programmable money movement beyond simple swipes.

Helcim appeals on large commercial draws and high-ticket residential GC work where interchange-plus clarity beats marketing flat rates—provided finance reviews monthly. Trial parallel math against incumbent processors on the same ticket mix. Confirm virtual terminal workflows for office staff while supers stay mobile. Choose Helcim when data supports it, not brand curiosity.
