Invoice Discount Bytesraw
A fast, flexible Discount button right on your customer and vendor invoices — apply a fixed amount, a global percentage, or a per-line percentage in seconds, with taxes kept accurate.
Discount any invoice.
Without breaking the taxes.
Invoice Discount Bytesraw adds a fast, flexible Discount button directly to customer and vendor invoices in Odoo. Instead of manually editing invoice lines or juggling separate discount products, your accounting team applies a discount in seconds — as a fixed amount, a global percentage, or a per-line percentage — straight from the invoice form.
It is built for finance and sales-admin teams who grant negotiated discounts on invoices while keeping taxes accurate and the ledger clean. The module respects multi-company setups, multi-currency invoices, and each partner’s language.
One-Click Discounting
A dedicated Discount button on draft invoices — open the wizard, choose a method, enter the value, apply. No manual line editing.
Three Discount Modes
Apply a fixed monetary amount, a global percentage across the invoice, or a per-line percentage on every product line.
Tax-Accurate by Design
Global percentage discounts are grouped by tax combination so every discount line carries the correct taxes.
Everything you need,
nothing you don’t.
Eight capabilities, each one focused on making invoice discounts fast, safe, and accurate.
Discount Button on Invoices
Adds a Discount button beneath the invoice lines on customer invoices and vendor bills. It appears only while the invoice is in draft, so posted documents stay untouched.
Fixed Amount Discount
Deduct an exact monetary value from the invoice via a single, tax-free discount line — ideal for round-number or negotiated flat discounts.
Fixed Percentage (Global) Discount
Apply one percentage to the entire invoice. Lines are grouped by tax combination and a matching discount line is created for each group so taxes recalculate correctly.
Per-Line Percentage Discount
Write the discount percentage directly into the native Discount field of every product line at once, keeping each line’s own subtotal and taxes intact.
Permission-Controlled Access
The Discount button is gated behind the Discount on Invoice security group, so only authorized users can grant discounts.
Automatic Discount Product
The module manages a reusable service product for discount lines per company, creating it automatically the first time it’s needed — no manual setup.
Multi-Company & Multi-Currency
Discounts are computed in the invoice’s own currency and company context, and discount line descriptions follow the partner’s language.
Percentage Safeguard
Percentage-based discounts are validated so they can never exceed 100%, preventing accidental over-discounting.
No setup headaches
The module works immediately after installation. Two things are worth reviewing.
Grant discount access
Open Settings → Users & Companies → Users, edit the relevant users, and add them to the Discount on Invoice group. Only these users see the Discount button.
Set the discount product (optional)
A per-company Invoice Discount Product is created automatically. To use a specific service product instead, assign it on the company record under Settings → Users & Companies → Companies.

Productive from day one
Three quick workflows for the three discount modes.
Apply a Fixed Amount Discount
Give a customer a flat monetary discount on a draft invoice.
Apply a Global Percentage Discount
Discount the entire invoice by a single percentage while keeping taxes correct.
Apply a Per-Line Percentage Discount
Set the same discount percentage on every product line individually.
Questions, answered
Quick answers to the most common questions.
Where does the Discount button appear?
On draft customer invoices and vendor bills, just below the invoice lines. It is hidden once the invoice is posted and for users outside the Discount on Invoice group.
What is the difference between the three discount types?
Fixed Amount adds one flat, tax-free discount line. Fixed Percentage discounts the whole invoice and creates discount lines grouped by tax combination. On All Invoice Lines writes the percentage into each product line’s native Discount field.
Will my taxes still be correct after a percentage discount?
Yes. Global percentage discounts are grouped by tax combination and per-line discounts use Odoo’s standard line discount, so tax totals recalculate correctly.
Do I need to create a discount product first?
No. A service product for discount lines is created automatically per company the first time it’s needed. You can override it with your own product on the company record if you prefer.
Can regular users apply discounts?
Only users added to the Discount on Invoice group can see and use the Discount button.
Does it work with multiple companies and currencies?
Yes. Discounts are calculated in the invoice’s currency and company context, and descriptions follow the partner’s language.
