Invoice
INV-1042
From: Bright Ledger Studio
Bill to: Client Company
Due date: Net 15
Item: Consulting services
Subtotal: $1,140.00
Discount: $0.00
Tax: $0.00
Total due: $1,140.00
Payment note: Pay by ACH, card, or the payment method in your agreement.
Formula used
- Subtotal
12 x $95.00 = $1,140.00- Invoice total
max(0, $1,140.00 - $0.00) + $0.00 = $1,140.00
Assumptions used
- Draft scope
- This draft covers one line item, discount, tax, due terms, and payment note; contract-specific terms still need review.
- Tax treatment
- Tax is calculated on subtotal after discount, using the editable tax rate you enter.
Use this as a practical draft. Add any contract-specific legal, tax, or payment terms before sending.
