Black Friday without losses: 5 reasons to digitize management and sell more

A Black Friday 2025 It will be on November 28, and the market is expected to move R$ 13.6 billion, a 16.5% growth compared to 2024, according to a study by consultancy Gauge in partnership with W3haus. With opportunities on the rise, Lucas Sousa, Commercial Manager at GestãoClick, a company specialized in technological solutions for business management, points out that many retailers make the mistake of continuing to use manual spreadsheets instead of adding innovation to their businesses through an Enterprise Resource Planning (ERP) system.

“Many small and medium-sized businesses manage to increase their sales volume on Black Friday but fail to balance their accounts, ending up at a loss. This happens due to a management problem, especially when this process is restricted to manual spreadsheets, which may work well at low volumes, but the more you sell, the less applicable they become. Without the right data, it is impossible to create an effective sales strategy for any retail date. In contrast, companies that invest in process automation are able to react more quickly and serve customers better,” elaborates the expert. 

5 Corrections to Sell More on Black Friday

Stop Making Sales Difficult: Black Friday offers have a specific day and time to end, which is why consumers seek quick information, clear promotions, and on-time deliveries. If a company takes too long to update prices or confirm an order, the customer buys from a competitor. It is in this context that Lucas Sousa warns against the use of manual spreadsheets, as they cannot keep up with this speed. “Black Friday requires speed and scale. When you try to manage promotions, inventory, and cash flow using spreadsheets, delays, human errors, and lost opportunities occur. Therefore, eliminating spreadsheets is no longer an option but a necessity“. 

Invest in Data Security: On Black Friday, the database becomes one of the company's main assets and requires total security. Relying on local spreadsheets is risky: a human error, computer failure, or incorrectly saved version can delete hours of work and compromise the sales history. Losing this data directly affects post-sales management, prevents analysis, and reduces productivity. To avoid this, the solution is to adopt an ERP system with cloud storage and automatic backups, ensuring secure versions, quick restoration, and operational continuity even during peak demand periods.

Don't Abandon POS Systems: Today, physical stores compete with each other and with e-commerce. Therefore, long queues and late confirmations lead to cart abandonment. And in this process, each lost customer represents a direct revenue loss, in addition to negative feedback. In this sense, it is important for entrepreneurs to invest in an ERP system that has a good POS tool and real-time inventory updates with integration between channels to update sales and inventory instantly. This way, the team serves customers faster and the customer leaves satisfied.

Automate Yourself: Process automation is one of the biggest gains from stopping the use of manual spreadsheets. Repetitive tasks, such as invoice issuance, financial entries, and inventory control, start to happen automatically. This automation through an ERP system reduces errors and saves hours of work. The entrepreneur gains more time to think about strategies and fewer concerns with manual tasks. Furthermore, it helps cut hidden costs, such as rework and human failures. 

Don't Wait for the Next Black Friday: Finally, there is still time to digitize management and profit more from this Black Friday. Start by mapping your company's manual processes, such as inventory control, invoice issuance and sales recording, and identify what still depends on spreadsheets. Then, choose a complete ERP system that integrates e-commerce, automates tax invoices, and generates real-time reports. Next, train your team and migrate data carefully to ensure a safe transition. Finally, automate reports and monitor results to make quick and strategic decisions. With an ERP, your company gains productivity, reduces errors, and faces Black Friday with efficiency and security.
