I built a tool to calculate real marketplace profit before listing products

Hi Indie Hackers 👋

I recently launched ProfitPilot — a pricing intelligence tool for online sellers.

The idea came from a simple problem I kept seeing:

Many sellers price products using marketplace calculators or spreadsheets, but these usually show only platform fees.

They often ignore:

• advertising costs

• VAT & taxes

• returns and refunds

• sourcing costs

• target profit planning

Because of this, sellers sometimes discover their real profit only after products go live — or worse, after losing money.

So I built ProfitPilot to answer one question:

👉 “What is my real profit before I list?”

Instead of tracking analytics after selling, ProfitPilot focuses on decision-making before listing.

Key ideas behind the tool:

✅ Platform-independent

✅ Reverse pricing (set profit → get selling price)

✅ Simple inputs, no complex dashboards

✅ One-time unlock (no subscriptions)

I’m currently looking for feedback from founders and sellers here.
