How a cell phone carrier scaled its marketplace business with Gierd

A cell phone carrier turned a high-risk, fragmented marketplace operation into a top-rated, high-growth business — doubling SKUs and more than doubling GMV in a single quarter on Gierd.

RESULTS AT A GLANCE

Results comparing Q4 2025 (Gierd ramp period) to Q1 2026 (fully ramped on Gierd).

Summary

A cell phone carrier set out to scale its marketplace business, but progress was constrained on nearly every front: a fragmented technology stack, disconnected reporting, customer-service gaps, strained relationships with the marketplaces, and account health that put its selling privileges at real risk. With no fraud mitigation, no loss recoupment, and no systematic way to ship from multiple warehouses, growth was capped and profitability was hard to see.

By consolidating its entire marketplace operation onto Gierd — and handing off customer service, repricing, listings, forecasting, fulfillment routing, and financial reporting — the carrier transformed a high-risk operation into a top-rated, high-growth business. In a single quarter of being fully ramped on Gierd, units grew 62%, GMV grew 107%, and active SKU count more than doubled, while Amazon Account Health climbed from at-risk levels to a healthy score.

The Challenge

Before Gierd, the carrier's marketplace business faced compounding operational and commercial obstacles:

• Fragmented systems and reporting — a patchwork tech stack with no single source of truth for performance or profitability.

• At-risk account health — an Amazon Account Health Rating at or below 200, putting the carrier at high risk of deactivation.

• Customer-service and relationship gaps — service issues and challenging relationships with the marketplaces, with no inside account-management support.

• No marketing access — the carrier was not offered the opportunity to participate in marketplace marketing programs.

• No fraud or loss protection — no fraud mitigation or management and no loss recoupment, leaving recoverable revenue on the table.

• Fulfillment constraints — no ability to systematically ship from multiple warehouses, limiting volume and speed.

The Solution

Gierd consolidated the carrier's entire marketplace operation onto a single platform that unifies sales, pricing, payouts, and supply into audit-ready financial data — giving the carrier true profitability visibility for the first time. Gierd's role spanned operations, commercial strategy, and intelligence:

• Customer service — Gierd took over marketplace customer service support for the carrier.

• Order & returns management — order and returns management plus returns reporting, including return rates and reasons.

• Multi-warehouse fulfillment — split-order management to systematically route orders to multiple warehouses.

• Pricing intelligence — Gierd’s repricer to maximize margin and win the buy box without racing to the bottom on price.

• Listings management — creation and optimization of all listings across every channel.

• Forecasting — supply-and-demand forecasting so the carrier can plan inventory accurately.

• Financial & account-health reporting — audit-ready financial reporting and ongoing account-health monitoring across channels.

• Marketplace analytics — margins, ASPs, and inventory velocity to inform allocation, plus promotions performance and revenue uplift.

A phased, low-risk rollout

The Results

Comparing Q4 2025 (the Gierd ramp period) to Q1 2026 (fully ramped on Gierd), the carrier's marketplace business improved across volume, assortment, and standing:

What This Means for Your Business

For enterprise sellers, the marketplace channel is too large — and too visible to your customers — to run on fragmented tools and manual processes. Poor account health threatens your right to sell; disconnected reporting hides where you actually make money; and pricing, fulfillment, and service gaps quietly cap growth.

The carrier's results show what becomes possible when those functions are unified. By consolidating operations on Gierd and gaining audit-ready visibility into profitability, the carrier protected its marketplace standing, recovered control of its margins, and unlocked rapid, sustainable growth — in a single quarter.
