Why is Flieber Better Than My Forecasting Spreadsheets?

In this article:

Almost every ecommerce brand we talk to is still managing inventory with spreadsheets. And we get it. Spreadsheets are flexible. You can customize them and seemingly do anything with them—until you can't.

As your brand grows, the data complexity quickly outpaces the capabilities of Excel or Google Sheets. That’s why we built Flieber: not to replace the spreadsheets entirely, but to make inventory planning actually work at scale.

Here are the three main reasons Flieber is the essential upgrade your operations need:

No More Manual Updates

With spreadsheets, every conversation about inventory starts with, "Wait, let me update the file." This constant manual data transfer is not only tedious but is the primary source of errors and outdated decisions.

Flieber just pulls the data for you. We automatically connect to your sales channels, inventory locations, and purchase order tracking to keep your core data: sales, inventory, and POs—always fresh and always synced.
The benefit: You spend zero time chasing numbers and all your time making decisions.

It Doesn't Break When Data Gets Big

Spreadsheets crash. As your eight-figure brand grows, managing inventory often requires a complex, interconnected set of multiple spreadsheets that are a pain to maintain. The risk of formulas breaking or files becoming corrupted is constant.

Flieber handles millions of rows like it’s nothing. We are built on a robust architecture designed for enterprise-level data volume.
The benefit: You can grow without your tools holding you back. You scale your products, sales channels, and warehouses with complete confidence in your system.

No More Guessing with Simple Averages

Spreadsheets often rely on simple, rigid formulas like average sales velocity for forecasting. But this calculation falls apart when dealing with the reality of modern commerce:

Sales are seasonal.
You have stock-outs that artificially depress historical demand.
You run promotions that create non-linear sales spikes.
You launch influencer campaigns that skew numbers.

Flieber solves this by running real AI transformer models on clean, contextualized data:

We analyze your sales behavior day by day and clean your historical data by accounting for stock-outs, influencer spikes, and promotions, improving forecasts by up to 40%.
Our models are much more accurate than simple spreadsheet guesses and account for many more subtle nuances in your sales behavior.
