In Detail
How It Works
Automatic Subtotals
Each line item multiplies quantity by rate to produce an amount. The subtotal is the sum of all line item amounts, recalculated instantly every time you add, edit, or remove an item. No manual math required.
Flexible Discount Options
Apply a percentage-based discount or a fixed dollar amount. Toggle the discount on or off with a single switch. The discount is clearly displayed as a separate line on the invoice so your client sees exactly what was deducted.
Smart Tax Calculation
Set your tax percentage and the system calculates the tax amount automatically. The tax is applied to the correct base amount depending on your tax-before-discount setting, ensuring compliance with your local tax rules.
Tax Before or After Discount
Different jurisdictions require tax calculated on different bases. Toggle between calculating tax before discount (on the full subtotal plus shipping) or after discount (on the reduced amount). One switch, full control.
Shipping Costs
Add shipping or handling costs as a separate line item in the totals section. Shipping is factored into the tax calculation automatically based on your tax-before-discount setting.
Accurate Total Due
The final total due is computed as: subtotal minus discount, plus shipping, plus tax. Every component is visible on the invoice and recalculated in real time. Your client sees a transparent, itemized breakdown of every charge.
Let the Math Do Itself
Add your line items and let the invoice builder handle subtotals, taxes, discounts, and shipping. Accurate every time.
