A national logistics provider came to us with a billing system that was a compliance risk, a manual bottleneck, and a structural liability. Two other vendors had quoted $150,000 and nine months. We delivered in ten weeks for $55,000 — and warranted it for a year.

The Challenge
The client's billing system was 15 years old and had never been replaced — only patched. Invoices required manual intervention at multiple stages. There was no audit trail. Billing errors required a person to trace back through raw database records. Every compliance review raised the same flags. The system worked until it didn't, and when it didn't, it took days to fix.
Before reaching us, the client solicited bids from two software firms. One quoted $135,000 and 8 months. The other quoted $160,000 and 9 months — with a change-order clause. Neither could explain what they'd actually build in phase one. The client had been burned before and wasn't willing to fund another discovery process that ended in scope creep.
Our Approach
We spent two weeks mapping every billing flow, every edge case, every manual override, and every database dependency. Nothing was assumed. Every behavior was documented before we wrote a single line of specification.
The spec defined exactly what the new system would do, what it would not do, and what success looked like at each milestone. The client signed off on it. We priced against it. No ambiguity, no change orders.
We rebuilt the billing engine on their existing stack — no new cloud platforms, no vendor lock-in, no retraining their team on unfamiliar tools. The replacement was designed to integrate with their current ERP from day one.
We used AI tooling throughout the development cycle to accelerate implementation without sacrificing quality. Every architectural decision was made by senior engineers. Every edge case identified in the audit was covered by automated tests.
Before cutover, the new system ran in parallel with the old one for two weeks. Every invoice generated by the new engine was compared against the legacy output. Discrepancies were investigated and resolved before a single live transaction touched it.
What We Delivered
A fully rewritten billing core with deterministic, auditable logic. No manual overrides required.
End-to-end invoice creation, validation, and delivery — triggered automatically at billing cycle close.
Every billing event, adjustment, and exception logged with timestamp, actor, and reason. Compliance-ready.
Real-time billing status, exception queues, and revenue summaries — accessible without touching the database.
Bidirectional sync with the client's existing ERP. Billing data flows in both directions without manual export.
Scripts to migrate 15 years of historical billing data into the new schema, with validation at every step.
