Calculator

How ISOs use the FoxCalc pricing calculator

Overview

The calculator is a single-page web application that ISOs access via a signed URL. No login required — the URL itself is the authentication.

Using the Calculator

Adjustable Fields

Depending on how the funder configured the offer, ISOs can adjust:

  • Purchase Price — Slider between the floor and ceiling set by the funder
  • Upsell — Slider from 0 to the max upsell allowed
  • Payment Count — Slider for number of payments
  • Payment Frequency — Toggle between available frequencies (daily, weekly, monthly)
  • Adjustable Fees — Individual fee sliders (if the funder marked fees as adjustable)

All computed values update in real time as sliders move.

Prepayment Schedule

If configured, a prepayment schedule table shows:

  • Time windows (months after funding)
  • Discounted factor rates
  • Amount saved per tier

Stipulations

If the funder requires documents, an upload section appears:

  • Required document names listed
  • File upload (10MB limit per file)
  • Upload status indicators

Submitting

When the ISO is satisfied with their configuration:

  1. Click Submit
  2. Review the confirmation dialog (shows selected terms)
  3. Confirm submission

After submission:

  • The funder receives the full payload via callback webhook
  • Notification emails are sent to configured recipients
  • The calculator shows a success confirmation
  • The deal status changes to "submitted"

Brand Theming

Each funder's calculator is branded with:

  • Custom logo
  • Primary and accent colors
  • Terminology overrides (custom field labels)

The calculator automatically applies the funder's brand from the deal configuration.
