The partnership

Why humm partnered with Voltflo

Finance, inside every journey.

The finance embed, inside the quote

This is the right-hand panel the customer sees when they open their quote. Cash or finance, toggled in place — no separate form, no redirect.

These figures are one product on one rate card. humm runs different rate cards for different products — rates are set by humm, not Voltflo.

More sales

Finance surfaced at the calculator, the plan, the email and the quote — at every point the customer is deciding, not just the price page.

Less admin

No separate finance forms. The option is in the report the customer already has open. They click, they apply, it's logged on the job.

Paid up front

The installer is paid in full on completion. The customer spreads the cost. You carry no debt and no chase.

See it on your own numbers — 20 minutes.
