Sample Project: Design & Development Sprint
Here is a realistic US freelance invoice showing the exact order of operations under our formula:
| Description | Calculation | Subtotal |
|---|---|---|
| Service: UX Design Sprint (1 Fixed Project) | 1 × $2,000.00 | $2,000.00 |
| Hourly: Frontend Development (20 hrs @ $100/hr) | 20 × $100.00 | $2,000.00 |
| Product: Custom Iconography Package | 1 × $500.00 | $500.00 |
| Gross Subtotal (Sum of all lines) | $2,000.00 + $2,000.00 + $500.00 | $4,500.00 |
| Early Payment Discount (10%) | 10% applied to Subtotal | - $450.00 |
| Taxable Amount Base | Subtotal ($4,500.00) − Discount ($450.00) | $4,050.00 |
| Sales Tax (8.25%) | 8.25% on Taxable Base ($4,050.00) | + $334.13 |
| Shipping / Courier Fee (Flat) | Added after tax calculation | + $25.00 |
| Invoice Total | Taxable Base ($4,050.00) + Tax ($334.13) + Shipping ($25.00) | $4,409.13 |
| Deposit / Amount Paid | Subtracted from Total | - $1,000.00 |
| BALANCE DUE (Final Payable Amount) | Total ($4,409.13) − Amount Paid ($1,000.00) | $3,409.13 |
Notice: preview totals and downloaded PDF totals match to the cent without rounding drift.
Financial Methodology & Tax Logic
Clear, transparent mathematical formulas and tax considerations.
Understand Our Math Logic & Formulas
InvoiceFree calculates financial totals according to US standard accounting practice:
- Subtotal: The sum of all line item amounts:
Σ (Quantity × Rate). - Line-Item Equal Treatment Rule: All line item types — service, hourly, fixed fee, and product items — roll into the Subtotal identically. No line item type is taxed differently or surcharged.
- Taxable Base: Tax is charged exclusively on
Subtotal − Discount. Discounts reduce the taxable base before tax calculation. - Sales Tax:
Taxable Base × (Tax Rate / 100). You can customize the tax rate and label (e.g. Sales Tax, VAT, GST). - Shipping & Delivery: Added as a flat, untaxed line after sales tax:
Total = Subtotal − Discount + Tax + Shipping. - Balance Due:
Total − Amount Paid. - Rounding Rule: Every line item is rounded to 2 decimal places, and each subsequent calculation step rounds to 2 decimal places. This prevents half-cent rounding drift between the screen preview and your PDF download.
Browser Storage & Privacy Architecture (~5 MB Limit)
Your privacy is absolute. InvoiceFree has no backend database, no login system, and transmits zero invoice data to our servers. All information lives exclusively in your browser's local cache (localStorage).
Key technical details:
- Local Storage Quota: Modern web browsers allocate approximately 5 MB of storage per website origin.
- Automatic Compression Archival: When your saved invoice drafts approach 80% of capacity (~4 MB), the system automatically archives older history items into compressed data packages under
archive_YYYYMMDDkeys, preventing data corruption or silent loss. - JSON Export / Import: You can export a complete backup of all your saved invoices, client profiles, and business settings as a single JSON file at any time.
- Instant Data Wipe: You can completely clear all saved invoices from your browser cache with one click in the History drawer.
