Northstar Software LLCMANUAL REVIEW

$1,850.00. Limited transaction context; purpose needs human review.

The problem

Software charges are easy to recognize. Patterns are harder to see.

A card or bank export can contain months of software transactions that look ordinary one by one. Put them together and repeated charges, recurring patterns, price creep, and unusual spend become easier to review.

01

Repeated charges

Two similar charges from the same vendor, only days apart, can be easy to miss in a long transaction list.

02

Price creep

Recurring charges can rise quietly over time. The scan shows observed changes across your transaction history.

03

Low-context spend

Material transactions with limited descriptions or unusual patterns can be surfaced for a human to investigate.

What it finds

A review list, not a black box.

Every flag is tied to transaction evidence. The scan does not pretend to know what a charge means when the CSV cannot tell us.

Potential duplicates
Repeated transactions worth checking

Same vendor, same or similar amount, and close dates. The result is labeled Potential duplicate — review, not a confirmed error.

Price creep
Observed amount increases

Shows the first and latest observed amounts, the change, and an annualized estimate only when the billing cadence is defensible.

Likely recurring
Regular transaction patterns

Identifies regular patterns from transaction history. These are likely recurring, not confirmed subscriptions.

Manual review
Charges that deserve context

Surfaces material or low-context transactions without claiming they are fraudulent, unused, or unnecessary.

How it works

Three steps. No account connection.

01

Export

Export software/SaaS transactions from a card, bank, or accounting system as CSV.

02

Load

Open the single HTML file and load your CSV. The analysis happens in your browser.

03

Review

Work through the flagged transactions and export a concise review list or printable report.

Your CSV stays on your device. The scan is designed to run locally in the browser. No account, API connection, or cloud upload is required to analyze your transactions.

What it does not do

Built from transaction evidence, not hidden account data.

The scan does not determine who uses a software product, how many seats are active, whether two tools overlap in functionality, what your contract says, or when a renewal is scheduled. It identifies transaction patterns for human review.
