One accurate ledger

CS Portfolio Manager aims to give users an accurate cost basis for items purchased from any marketplace, current market value and matched sales—giving users all the insight needed to track performance. Additionally, we aim to provide a comprehensive trade-up calculator, allowing users to use actual cost prices from the recorded ledger and find positive-EV contracts. Trade-ups recorded in the calculator will consume the inputs and assign the cost basis to the output.

Bring the history together

Import supported marketplace records and map additional CSVs without handing over a Steam password or trade access.

Reconcile what changed

Compare purchases, sales, current inventory and trade-up inputs without hiding uncertain matches behind one headline number.

Keep the evidence

Export the single ledger into one file, giving the user complete insight into performance.

Thank-you for testing

Three months of Trader free at launch

Selected beta testers receive a fixed three-month entitlement to the Trader subscription tier. No payment method, automatic charge, positive review or public post is required.

Who is the first beta intended for?

The first beta is best suited to active CS2 traders who buy and sell across multiple marketplaces, regularly complete trade-ups, or need to reconcile purchases, sales, fees and current inventory from fragmented records.

Does joining guarantee beta access?

No. We plan to invite 10–30 testers in small rounds. Joining early does not create a queue position or guarantee selection.

What happens after I join?

After email confirmation, you may receive occasional waitlist and build updates. People who request beta consideration may also receive a short screener.

What does the tester reward require?

The reward is for selected participation and candid testing under the beta terms. It is not conditional on praise, a review, a referral or a social-media post. The entitlement ends without a charge.

Is early November guaranteed?

No. Early November 2026 is the current aim and depends on product, privacy, provider and security checks. Confirmed contacts will receive a factual update if that plan changes.

Is this affiliated with Valve, Steam or a marketplace?

No. CS Portfolio Manager is independent software from CSPORTFOLIOMANAGER LTD and is not affiliated with or endorsed by Valve Corporation, Steam or any marketplace.
