Split invoices, guided every step of the way
A guided, preview-driven wizard breaks any draft invoice, vendor bill, or credit/debit note into multiple documents — with GL and cost-center allocation, full lineage, and nothing created until you approve the preview.
The problem
Splitting an invoice by hand means duplicating it, deleting lines, and re-keying totals — slow, error-prone, and risky for the audit trail. Odoo has no guided way to do it, so accountants improvise and hope the books still balance. Ambiguous "split by deletion" tools leave users unsure which document survives, and unmaintained legacy apps offer no GL or cost-center guidance at all.
The solution
Invoice Splitting adds a guided wizard to every draft invoice, bill, and credit/debit note. Choose equal, percentage, milestone, or installment splitting — or extract specific lines — preview the resulting documents and their GL/analytic allocation before anything is created, then let the system keep parent and child linked, in sync, and ready for approval.
Everything you need to split with confidence
Every capability below is implemented in the module.
Proportional Splitting
Split a draft invoice into equal parts, custom percentages, milestone amounts, or a full installment schedule — the wizard computes every part's line items and totals automatically.
Extract Lines
Move selected lines and quantities out of the original document into a new one — replacing ambiguous "split by deletion" language with a clear, visual extract action.
Pre-Commit Preview
Review every resulting document, its lines, and its totals before anything is created. Nothing commits until you confirm the preview.
GL & Analytic Allocation
Assign each split part its own general ledger account and analytic (cost-center) distribution, prefilled from the source lines and ready to adjust.
Parent/Child Lineage
Every split document keeps a persistent link back to its source and siblings, with a Split Docs smart button and full history visible on the record.
Manager Approval Workflow
Route unusual splits through an approval step before they are finalized, with approvers drawn from the accounting manager group.
Reversible Splits
Undo a proportional split (equal, percentage, milestone, or installment) and restore the original document in one action.
Split Reconciliation Report
Generate a printable report reconciling every document in a split family — amounts, allocations, and status at a glance.
Works Across Document Types
One consistent wizard for customer invoices, vendor bills, credit notes, and debit notes — no separate tools to learn.
