In 2025, launching an online store is easier than ever thanks to platforms like Shopify, PrestaShop, or TikTok Shop. But behind sales growth is often a critical problem: Financial Management.
Many e-retailers make the same mistakes... which can put their business at risk. Let's discover the 5 most frequent ones, and especially how to avoid them.

1. Not Monitoring Your Cash Flow in Real Time

👉 Mistake: content yourself with sales reports from your e-commerce platform.
Without taking into account fees, commissions, refunds and fixed charges, it is easy to overestimate your available cash.

💡 Solution: use a Financial cockpit That consolidated sales, fees and payments for a clear vision of cash flow.

2. Confusing Turnover and Margin

👉 Mistake: celebrating a high turnover without analyzing real profitability.
Between advertising (Meta Ads, TikTok Ads), logistics and returns, a turnover of €100,000 can hide an almost zero margin.

💡 Solution: follow the Net margin By product, by channel and by marketing campaign.

3. Forget to anticipate payment deadlines

👉 Error: depending only on Shopify, PayPal, or TikTok Shop payouts without providing a buffer cash flow.
These delays create cash flow tensions.

💡 Solution: set up a Working Capital and follow cash flow forecasts.

4. Do not centralize your data

👉 Error: multiplying tools (Shopify, PrestaShop, PrestaShop, PrestaShop, Stripe, PayPal, Excel) without a consolidated vision.
The result: loss of time and blind decisions.

💡 Solution: connect your tools to a cockpit that aggregates sales, finances and administration.

5. Neglecting Administration and Compliance

👉 Error: delaying invoices, quotes, or tax returns.
In the event of an audit, it can be expensive (penalties, adjustments).

💡 Solution: automate the issuance of invoices and store documents in a secure space.
