Ledger Studio

A freelance workspace for creating quotes, understanding pricing, and protecting project scope.

Live Demo: [Add your live demo URL here]

Ledger Studio started with a simple question:

Is the price of my freelance project actually sustainable for me?

Most quote builders are good at calculating:

Quantity × Rate = Price

But that only tells you what the client is paying.

Ledger Studio tries to make the freelancer side of the deal easier to understand too.

What is Ledger Studio?

Ledger Studio is a browser-based freelance workspace for:

• Creating professional quotes
• Checking the economics of a deal
• Finding work that may have been missed from the quote
• Reviewing proposal risks
• Testing scope-creep situations
• Managing active projects

The goal is not to tell freelancers what they should charge.

The goal is to make the information behind a quote easier to see.

---

Freelancer Baseline

Ledger Studio has a Freelancer Baseline that lets you enter:

• Monthly survival expenses
• Desired working hours per month

From this, the app calculates a personal minimum hourly rate.

This is not a market-rate calculator.

It does not use an external database to tell you what your rate should be.

It is simply a personal financial floor.

If a quote falls below that floor, Ledger Studio can flag it.

---

Hidden Work Detector

Freelance projects often contain work that doesn't appear clearly in the original quote.

For example:

Build website — 40 hours

The actual project may also involve:

• Testing
• Deployment
• Configuration
• Analytics setup
• SEO work
• Revisions
• Other supporting tasks

Ledger Studio has a Hidden Work Detector that checks the quote description, scope of work, and terms against predefined rules and keywords.

When something is detected, you can:

• Add it to the scope
• Mark it as an internal task
• Ignore it

Important limitation

The detector is rule-based.

It is not an AI system that understands every possible hidden task.

Because of that, it can miss things or flag something that is not relevant.

---

Proposal X-Ray

The Proposal X-Ray performs a pre-flight check of a proposal across areas such as:

• Scope clarity
• Revision protection
• Payment terms
• Timeline
• Client responsibilities
• Supporting work
• Pricing health

It produces a proposal health score and points to sections that may need attention.

---

Scope Creep Simulator

The Scope Creep Simulator lets you test how a project can change when a client asks for additional work.

The simulation can change:

• Scope
• Estimated workload
• Price
• Effective economics

You can respond by:

• Accepting the change
• Charging extra
• Swapping existing scope
• Protecting the original scope

It is a simple way to think through scope decisions before dealing with them on a real project.

---

Quotes & Pricing

The quote builder supports:

• Freelancer / company information
• Client information
• Quote metadata
• Dynamic line items
• Quantities
• Hourly or unit rates
• Tax
• Discounts
• Multiple currencies
• Payment milestones
• Scope of work
• Terms and revision policies

The application calculates line-item totals, subtotal, tax, discount, grand total, and effective hourly rate.

Payment milestones are validated so that they add up to exactly 100% before export.

---

PDF Export

Quotes can be previewed in real time and exported as PDF directly from the browser.

The PDF is generated on the client side using @react-pdf/renderer.

---

Active Projects

Accepted quotes can be converted into active projects.

Projects can track:

• Client
• Contract value
• Start date
• Due date
• Current status

Available statuses:

In Progress
Awaiting Client
Completed
Canceled

---

Privacy

Ledger Studio is designed to work locally in the browser.

The core workflow does not require:

• Login
• An account
• A backend database
• Cloud storage
• User tracking

Quote data, freelancer settings, sender information, and projects are stored in browser localStorage.

Limitations

Ledger Studio is intentionally not trying to solve every freelancing problem.

Freelancer Baseline

A personal minimum rate does not tell you what a specific client or market will actually pay.

Hidden Work Detector

The detector relies on predefined rules and keywords, so it can miss relevant work or flag irrelevant work.

Proposal Analysis

A proposal can still be a bad deal even when the numbers look good.

These tools are meant to make potential problems easier to notice, not make the decision for the freelancer.

---

Why I Built It

I built Ledger Studio because I wanted freelance proposals to answer more than:

"How much does this project cost?"

I also wanted them to make it easier to answer:

"What does this deal actually mean for me?"

A lot of the system is intentionally deterministic.

Instead of having a model invent a price or tell the freelancer what they should charge, Ledger Studio uses information the freelancer already knows and makes the economics, workload, and proposal risks easier to see.
