How QuickBills Works Under the Hood
Complete transparency into how calculations are performed and how your invoice data is handled.
How QuickBills Calculates Totals
All mathematical operations in QuickBills are executed locally using standard commercial accounting formulas to guarantee consistency:
| Calculation Component | Applied Mathematical Formula |
|---|---|
| Line Item Amount | Item Quantity × Unit Price |
| Gross Subtotal | ∑ (All Line Item Amounts) |
| Discount Amount | Subtotal × (Discount Rate ÷ 100) |
| Taxable Base | max(0, Subtotal − Discount Amount) |
| Tax Amount | Taxable Base × (Tax Rate ÷ 100) |
| Net Total Due | Subtotal − Discount Amount + Tax Amount |
QuickBills calculates discounts prior to calculating taxes, ensuring tax is only assessed on the actual discounted net base.
How QuickBills Handles Your Data
QuickBills was deliberately designed with a client-first privacy architecture:
- Zero Server Storage: Your invoice line items, pricing, customer names, and banking coordinates never leave your browser. They are not transmitted to or stored on any server database.
- Client-Side PDF Generation: PDF files are assembled directly on your device using HTML5 canvas capture and local PDF rendering. No external rendering service receives your document.
- Direct Print Support: Dedicated print stylesheets (@media print) ensure that clicking "Print Invoice" formats an exact A4 or Letter page for your local printer without browser clutter.
Because your data lives in browser memory, remember to download your PDF before closing or refreshing your browser tab.
What is an Invoice and Why is it Necessary?
An invoice is an itemized commercial document that records a transaction between a seller and a buyer. When services are delivered or goods are shipped under agreed payment terms, the invoice establishes a clear payment request stating what was provided, the total amount owed, and the deadline for settlement.
In addition to requesting payment, invoices are indispensable for bookkeeping. They form the basis of Accounts Receivable (A/R) for sellers and Accounts Payable (A/P) for buyers, providing the verifiable audit trail required for business accounting, expense tracking, and corporate tax reporting.
Invoice vs. Receipt: The Key Difference
An invoice requests payment before funds are transferred. A receipt is issued after payment has been completed as proof of settlement. Both are vital records at different stages of the billing cycle.
When Should an Invoice Be Issued?
- Upon Milestone or Project Completion: Issue your invoice promptly once work is approved to keep cash flow predictable and deliverables fresh in the client's mind.
- Agreed Project Milestones: For multi-week engagements, dispatch invoices when defined project checkpoints or deliverables are approved.
- Recurring Billing Intervals: For ongoing retainer agreements or maintenance plans, issue invoices on a predictable monthly schedule (such as the 1st or 15th).
- Upfront Project Deposits: For custom commissions or new clients, issue a deposit invoice before initiating extensive billable hours.
What Should Every Invoice Include?
To prevent payment delays and accounts payable rejections, verify your invoice contains these essential components:
1. Header & Numbering
Display the word "Invoice" clearly with a unique, sequential invoice number (e.g., INV-1001) for audit and tracking purposes.
2. Issuer & Client Details
Full trading names, business addresses, contact email addresses, and phone numbers for both your business and the client.
3. Issue Date & Due Date
State the specific date the invoice was issued and the calendar deadline for payment (e.g., Net 14 or Net 30).
4. Itemized Deliverables
Detailed row-by-row descriptions of each task or merchandise delivered, including quantities, unit prices, and line subtotals.
5. Subtotals, Taxes & Discounts
A transparent financial summary detailing gross subtotal, applied discount percentage, sales tax or VAT, and net amount due.
6. Payment Coordinates
Remittance details such as bank transfer information (ACH, IBAN, routing numbers) or payment links so clients know how to pay.

Avoid vague labels like "Design Work". Detail the scope (e.g., "Homepage UI Redesign & Mobile Optimization - 12 hrs @ $85/hr") to avoid approval questions.
