Software studio · Chicago, IL

Software for the parts of a business that make money.

Herlehy Development designs and builds the systems behind revenue: lead and sales tracking, payments and payouts, subscriptions and reporting. From the first database table to production.

Four systems we designed and built, shown as they actually run: a contractor’s CRM, a real-money tournament platform, a creator marketplace and a paid course.

01

Contractor CRM & ad reporting

A Chicago-area home improvement company

  • Call queue fed by WhatConverts every 15 minutes, oldest uncontacted lead first
  • Revenue, close-rate and appointment-outcome reporting synced from improveit360
  • Read-only Google Ads and Meta reporting shown next to real leads, as cost per lead

Built with Next.js · Supabase · WhatConverts · improveit360 · Google Ads API · Meta Marketing API

What we build

Lead and sales systems

CRMs and call queues that pull in calls, leads and sales history, so a sales team works from one list instead of four tabs.

WhatConverts · improveit360 · Supabase

Payments and payouts

Deposits, escrow, payouts and identity checks, built to be safe when a request arrives twice and to recover when a provider fails.

Stripe · PayPal · Stripe Identity

Subscriptions and gated content

Paid memberships where access follows billing, including refunds and cancellations, with no content leaking to non-members.

Stripe · Mux

Reporting

Dashboards that put advertising spend next to real leads and revenue, so cost per lead is a number rather than a guess.

Google Ads API · Meta Marketing API

How the work is built

  1. 01

    Money paths are tested before they ship

    On LastRound, every deposit and payout path was covered end to end: the normal case, duplicate requests and failure recovery.

  2. 02

    Read-only unless writing is the job

    The contractor dashboard reads advertising data to report on it. It cannot create, pause or change a campaign.

  3. 03

    Built to be handed over

    For Dirty 630, the codebase and infrastructure were handed over to the client in full at the end of the engagement.
