Refreshed documentation
Why net revenue alone isn’t enough
Odoo’s standard flow computes subtotal as
qty × price × (1 − discount%). The
discount portion vanishes into net revenue. CFOs can’t measure
discount-to-sales ratio. Auditors can’t tie posted PnL to the
discounts that produced it.
Without this module
- Gross sales total — not visible. Sales Revenue posts net of discount only.
- Discount given total — requires SQL query against invoice lines every month-end.
- Discount-to-sales ratio — manual calculation; no PnL drill-down possible.
- Per-category tracking — impossible without custom report.
- Audit trail — discount lives in invoice line metadata, not in the GL.
With this module
- Gross sales total — Sales Revenue at NET on the original line + a gross-up counter on the same account: trial-balance sum rolls up to GROSS. Tax basis unchanged.
- Discount given total —
dedicated GL line per invoice line, flagged
is_discount_line=True. PnL drill-down works. - Discount-to-sales ratio — one click in Accounting → Reporting → Profit and Loss.
- Per-category tracking —
configurable Discount Customer Account per
product.category. - Audit trail — DISC journal split cross-references each invoice line.
See the journal split in action
Same invoice line — qty 10, price 1,000, discount 15%, VAT 10% — posted with and without the module.
What you also get
Pre-discount columns
Five new optional columns in the invoice line editor: Undiscount, Disc Untaxed, Undiscount Tax Basis, Tax Basis. Hidden by default — toggle on per-user.
Refund + purchase symmetry
Works on customer invoices, customer refunds, vendor bills, and vendor refunds. Sign flips correctly; direction matrix documented in README.
Clean re-post flow
Edit discount %, reset to draft, re-post — DISC lines regenerate from the new value. No orphans, no manual cleanup. Idempotent.
Two-level configuration
Set defaults on
product.category, override per
product.template. Granular tracking where you need
it, sensible defaults everywhere else.
Analytics-aware
Inherits analytic_account_id
and analytic_tag_ids from the source line. Analytics
breakdown remains intact across the DISC split.
Tax-safe
Tax basis computed on post-discount net, exactly like Odoo standard. The DISC split is GL-only — your VAT return, SPT, output VAT all unchanged.
How it compares
| Reporting need | Standard Odoo | With this module |
|---|---|---|
| Gross sales total in trial balance | net only | ✓ gross posted |
| Discount given as a GL line | ✗ invisible | ✓ dedicated account |
| PnL drill-down to discounts | ✗ | ✓ one click |
| Per-category tracking | ✗ | ✓ product.category field |
| Per-product override | ✗ | ✓ product.template field |
| Refund / vendor side | net only | ✓ sign-flip symmetric |
| Tax basis | post-discount | post-discount (unchanged) |
| Re-post after edit | n/a | ✓ idempotent |
Direction matrix — all four move types
Same code path handles sales and purchases, invoices and refunds.
Sign flips automatically based on move_type.
| Move type | Debit | Credit |
|---|---|---|
out_invoice |
Discount Customer Account | original income account |
out_refund |
original income account | Discount Customer Account |
in_invoice |
original expense account | Discount Vendor Account |
in_refund |
Discount Vendor Account | original expense account |
Configure without code
Three setup steps, less than three minutes. No Python, no XML, no module restart.
Create discount accounts
Accounting → Chart of Accounts → create two new accounts: Discount Given (income-other) and Discount Received (expense-other). Codes follow your local CoA.
Map to categories
Inventory → Configuration → Product Categories → pick category → under Account Properties, set Discount Customer Account and Discount Vendor Account.
(Optional) per-product override
For products that need separate tracking (slow-mover vs
promo discount, etc.), open
product.template → Accounting tab →
override the account. Falls back to category if blank.
Resolution order at posting time: product.template override → product.category default → skip (no DISC split generated for that line). Blank both = invoice posts normally, exactly like standard Odoo.
Fields added — ready for custom reports
Six new fields on account.move.line, all stored and
computed. Use them in QWeb invoice templates or custom XLSX
exporters.
| Field | Purpose |
|---|---|
price_undiscount |
Line total before discount % applied |
price_discount_untaxed |
The discount amount, untaxed — value of the DISC journal split |
price_undiscount_untaxed |
Tax basis as if no discount were applied |
price_untaxed |
Actual taxable base (= price_subtotal, materialised for reports) |
price_unit_undiscount_untaxed |
Per-unit price, pre-discount, post-tax-removal |
is_discount_line |
True on the auto-generated DISC split rows — use to filter them out of reports |
