The Challenge

Trace Black is an e-commerce apparel brand built on a simple idea: quality camisetas and kits sold directly to customers through marketplaces. The company had found early success selling through Mercado Livre and Shopee, building a loyal customer base and establishing a recognizable brand in the Brazilian market.

However, success brought complexity. As the business grew, the team was juggling multiple sales channels, inconsistent marketing spend, and financial data scattered across spreadsheets and bank accounts. There was no clear picture of profitability. Advertising costs were high, but nobody could say with certainty whether campaigns were actually working. Inventory decisions were made on gut feel rather than data. And the financial picture was murky—investments, personal withdrawals, and business expenses were all mixed together, making it impossible to know if the company was truly profitable.

"We were growing, but we couldn't see where the money was going," one team member explained. "We had data everywhere, but no real visibility into what was actually working."

The core problem wasn't a lack of effort. The team was executing constantly—testing new products, running ads, managing inventory. But without a unified system to track performance and finances, every decision felt like a shot in the dark. Marketing budgets were being spent without clear ROI. Supplier negotiations were happening without cost visibility. And the financial statements didn't match reality.

The Solution

The turning point came when the team decided to stop managing by instinct and start managing by data. They implemented a structured financial planning system and began optimizing every part of the business with real numbers.

The first step was financial clarity. The team adopted a comprehensive planning framework that separated business expenses from personal withdrawals, tracked every source of revenue, and mapped costs to specific products and channels. This wasn't just about accounting—it was about understanding the true health of the business.

"Once we could see the real numbers, everything changed," the team reflected. "We stopped guessing and started deciding."

With financial visibility came the ability to optimize marketing. The team began analyzing campaign performance in detail. They paused underperforming ads, reallocated budgets to top performers, and focused on products that actually converted—especially kits, which drove higher order values. They tested new keywords, adjusted creative, and monitored metrics like cost per sale and conversion rate obsessively.

At the same time, they tackled the supply chain. Negotiations with regional suppliers led to better pricing and faster delivery times. The team also implemented inventory controls, focusing on products with real demand rather than holding slow-moving stock.

The organizational commitment was total. Everyone understood that data-driven decisions would replace assumptions. Marketing decisions were made weekly, not monthly. Financial reviews became routine. And the team aligned around a single goal: sustainable, profitable growth.

The Transformation

The results came quickly and were measurable.

On the marketing side, the cost per sale on Mercado Livre dropped by approximately 50%—from 13.54 to 6.70 in just weeks. This wasn't a one-time win; it reflected a new discipline in how campaigns were managed. Shopee, which had been underperforming, saw revenue grow by over 275% in a single month once the team focused attention there. Conversion rates improved. The team was doing more with less.

The financial picture became clear. By separating personal withdrawals from business expenses and tracking every cost, the company could finally see its true profitability. Margins improved. Cash flow became predictable. The team could make investment decisions with confidence.

Supply chain improvements added another layer of benefit. Faster delivery times improved customer satisfaction. Better supplier pricing improved margins. And inventory management meant less capital was tied up in slow-moving stock.

But the real transformation was cultural. The team went from managing by feel to managing by data. Decisions that once took days now took hours. Hypotheses were tested and validated. Failures were identified quickly and corrected. The business became more agile, more responsive, and more profitable.

"We're not just bigger now—we're smarter," the team said. "We know what works, and we can scale it."

Looking ahead, the foundation is in place for continued growth. The team has proven they can optimize across multiple channels. They understand their unit economics. They have supplier relationships that support scaling. And they have the financial visibility to invest confidently in growth.

The journey from scattered systems to streamlined operations wasn't complicated. It required discipline, commitment to data, and a willingness to change how decisions were made. But the payoff—in profitability, clarity, and confidence—has been substantial. Trace Black is no longer a business that's growing despite its systems. It's a business that's growing because of them.
