“A wholesale buyer wants 1,800 units of the travel kit. Can we take the order?”
| Metric | Accept all | Split 1,100 now / 700 after the next PO |
|---|---|---|
| Amazon stockout days | 21 | 0 |
| Revenue, next 90 days | $384K | $401K |
| Margin | $112K | $127K |
| Cash low point | $64K | $78K |
Recommendation Split the order: no Amazon stockout, more margin and a higher cash low point.

Trusted by hundreds of brands
For most product brands, inventory is the biggest use of cash. Every major decision either adds to it, draws it down, or depends on it being there. That’s why Flieber starts with inventory, and why getting it wrong costs more than almost any other mistake.
A PO locks up cash for months. Buy too much and it sits in a warehouse; buy too little and you stock out.
A discount only pays off if you have the units to sell. Run it on thin stock and you trade margin for a stockout.
Demand you pay for is wasted if the product runs out mid-campaign.
Credit lines and inventory loans are sized on stock value and sell-through. What you can borrow depends on your inventory numbers being right.
Inventory decisions commit cash for months. With Flieber, your team stays in charge of them, while Flieber’s AI and your own agents take on everything around them.
Set the objectives and constraints, add the context no system has, and make the final call on every decision that commits cash.
Keep your data consolidated and current, watch every SKU and every signal, prepare each decision with the reasoning behind it and carry it out once you approve. Your own agents work from the same data, context and engine through MCP and API.
Optional. Specialists in inventory planning and in Flieber who join your S&OP meetings, act as a sounding board for your decisions and keep the data your team and your agents rely on accurate.
You decide how much runs on its own. By default, every change waits for your approval.
An agent on a spreadsheet can sound confident and still get inventory wrong. It doesn’t know which listings are the same product, what’s inside a bundle or that last month’s dip was a stockout. Before running your brand with agents, someone has to keep the data true. Each layer adds something the one below it doesn’t have.
Your data
Sales, orders, inventory and shipments arrive from every connected system, each in its own format, and are reconciled into one record. Gaps and anomalies surface here, before anything is planned on them.
Business context
The records become a model of how your business actually works: which listings are the same product, which components make a bundle, which supplier ships to which warehouse and what a stockout did to last month’s sales.
Planning engine
Proprietary algorithms do the math: forecasts, projections and recommendations computed against your real constraints, shaped by the business context of more than 1,000 commerce brands since 2019.
Collaborative AI
The AI layer translates between the engine and whoever is asking, your team or your agents. It turns a question or an objective into a calculation, explains the result in plain language and runs the follow-up work on schedule.
Where you work
The same answers reach you wherever you work: in the Flieber app, Slack and Google Sheets, or through Claude and your own agents via MCP and API.
Control
Nothing changes in your systems without passing the approval rules you set. Your data is never sold or shared, and Flieber does not train on it.
Each module answers one of the questions every inventory planner asks. Flieber comes with all five; teams building their own tools with AI can start with the data layer alone.
One current, reconciled view of every channel, warehouse and supplier, ready for your team or your own tools. Available on its own.

On-hand, inbound and days of cover by SKU, channel and location.
SKU-level forecasts per channel, reconstructed through stockouts and promotions.
Impact on inventory, revenue, margin and cash before anything is committed.
Replenishment by supplier, with MOQs, lead times and container fill applied.

It depends less on your size than on how complex your operation is.
Run it yourself
For you, the hard part isn’t the planning logic. It’s the plumbing: data that flows correctly and carries the right context, so every report, workflow or agent works from the truth.
What you get: The Flieber app, plus Flieber’s data and context modules through MCP and API. Build the reports and workflows you need on top, and they keep working as you add channels, products or suppliers. Building everything yourself? Start with the data layer alone.
Let our planners help you run it
For you, the hard part is the decisions themselves. There are more edge cases than an in-house tool will cover, and a mistake ties up cash for months.
What you get: Everything in Self-Serve, plus Flieber’s specialized planners as a sounding board for your decisions. They master the platform, keep the data behind your decisions accurate, take part in your S&OP meetings and help run your planning practice, drawing on experience from more than 1,000 brands.

Flieber considers everything no other software picks up. It killed our Amazon stockouts.
Flieber is helping us effectively manage stock across all of our sales channels by customizing our calculations to the data points that matter most.
We have always been challenged with out-of-stock inventory and long lead times. Flieber was a game changer for us.
Flieber has allowed me to reduce manual work while planning and forecasting products, and to handle different regions and sales channels in a single place.
Flieber creates a ‘one stop shop’ where I can see demand-level data across all my brands and make educated replenishment decisions.
Planners bring judgment. They know the supplier who always ships late, the retailer who over-promises, the promotion that isn’t in any system yet and the hidden rules that impact each decision. AI brings speed, vigilance and precision: it watches every SKU, every channel and every change, around the clock. Neither is enough on its own. Flieber puts them on the same team. Flieber’s AI gives teams the most up-to-date contextualized data; your people make the calls; Flieber prepares every decision and carries it out once approved.
Our vision is to give every commerce brand operator the tools to focus on what matters most: making the best decisions and driving progress. By making contextualized data always available, removing repetitive tasks and streamlining complex workflows, we help operators spend less time on clerical work and more time actually making impactful decisions.
We’re building more than a product. Alongside industry professionals, we’re building a new gold standard for operations at modern commerce brands. A future where tech complements expertise, where commerce teams operate with confidence and efficiency and where every operator has the freedom to do their best work.
