Recovering Leaked Carrier Spend for a Multi-Brand Fulfillment Agency

A multi-brand ecommerce fulfillment agency moves ~10K shipments a month across ~20 Shopify brands — but Shopify, ShipStation, the carrier invoices, and QuickBooks never talked to each other. Untraceable carrier adjustments quietly leaked ~$6K/month, and monthly client billing ate roughly a week of manual work. We built the integration and automation layer that reconciles every shipment and assembles billing in minutes. (Engagement is in UAT — figures below are projected/target.)

The Company

A multi-brand ecommerce fulfillment agency that runs storefronts and shipping operations for roughly 20 consumer brands, processing on the order of 10,000 shipments per month. Each brand sells on Shopify; orders flow to ShipStation for fulfillment; parcels ship via UPS, FedEx, and Mail Innovations; and client billing is reconciled in QuickBooks. The systems each do their job — but nothing connects them, so the agency stitches exports together by hand to figure out what each brand actually owes.

The Problem

Carrier invoices arrive full of after-the-fact adjustments — dimensional reweighs, surcharges, address corrections — that never make it back to the original order. With ~10K shipments a month across three carriers, those adjustments were impossible to trace by hand, and an estimated ~$6K/month of leaked spend went unbilled or unrecovered. On top of that, assembling each brand's monthly invoice meant manually cross-referencing ShipStation exports, carrier statements, and Shopify orders — roughly a week of work, every month, with errors baked in.

We know we're losing money on carrier adjustments — we just can't see where.

Closing the books each month means a week of someone living in spreadsheets.

Every brand's bill is a manual reconciliation against three different carrier statements.

What We Built

We built the custom integration pipeline that connects Shopify → ShipStation → carrier invoices (UPS, FedEx, Mail Innovations) → QuickBooks into one reconciled view of every shipment. On top of it sits a deterministic reconciliation and billing-automation layer: the matching and the math are done in auditable software, not by an AI. AI is used only for the ambiguous parts — parsing inconsistent carrier-invoice formats and summarizing exceptions for a human — and never to compute a charge.

Unified Order Pipeline

Connects each brand's Shopify storefront to ShipStation and ties every fulfilled parcel back to its originating order — one normalized record per shipment across all ~20 brands.

Carrier Invoice Ingestion

Ingests UPS, FedEx, and Mail Innovations invoices and normalizes their inconsistent formats into a single schema. AI assists only with ambiguous line parsing — it never decides what is owed.

Three-Way Reconciliation

Deterministically matches each shipment to its carrier charge and to the amount billed to the brand — auditable line by line, so every dollar ties out. The math is software, not a model.

Leakage Detection

Flags untraceable adjustments — reweighs, surcharges, address corrections — that previously slipped through, turning ~$6K/month of invisible leakage into a recoverable, line-itemized list (projected).

Automated Client Billing

Assembles each brand's monthly invoice from the reconciled data and pushes it into QuickBooks — collapsing roughly a week of manual cross-referencing into minutes (projected).

AI Exception Assistant

Summarizes the exceptions a human still needs to review — odd adjustments, unmatched parcels, format anomalies — in plain language, so the ops team triages in minutes instead of hours.

The Timeline

Not 6 months. Not 12 months. Weeks.

Week 0

Discovery Call

Mapped the order-to-invoice flow, the carrier mix, and where the manual billing time actually goes.

Week 1–2

Pipeline Prototype

Connected Shopify and ShipStation and ingested a month of real carrier invoices to prove the matching logic.

Week 2–3

Reconciliation Engine

Built the deterministic three-way match and validated it against a known billing period the team had closed by hand.

Week 3–5

Billing Automation

Automated per-brand invoice assembly and the QuickBooks push, with leakage flagged as a reviewable list.

Week 5–6

UAT

Agency is validating projected recovery and billing accuracy against live months before full cutover.

Next

Production Cutover

Move monthly close onto the automated pipeline and begin tracking realized recovery against projections.

The Reaction

For the first time we can point at a specific shipment and a specific carrier adjustment and say exactly what it cost us. That alone changes the conversation with our carriers.

Founder & CEO

Billing used to be the week everyone dreaded. Watching it assemble itself from reconciled data — and tie out to the penny — is a different business.

The part that sold me is that the math is deterministic. The AI summarizes the weird stuff; it never decides what a brand owes.
