Payment Reconciliation & Settlement Matching for Odoo

This module gives Odoo a first-class settlement layer. We build a settlement.batch model that ingests each gateway's payout/settlement file (CSV, Excel, or direct API pull where the gateway exposes one) and explodes it into settlement.line records, each carrying the gateway transaction id, gross amount, fee, tax on fee, net, currency, and payout date. A matching engine then reconciles those lines against Odoo's account.payment, sale.order, and pos.order records using a configurable rule set — exact transaction-id match first, then order reference, then amount-plus-date tolerance windows. Fields are computed with proper @api.depends so gross, fee, and net always foot; matched lines auto-post the processing fee to the expense account you designate and, for cross-currency payouts, book the FX gain/loss line, all through account.move so the audit trail is native. Anything the engine cannot confidently match lands in an exception queue instead of being force-fit.

The build is grounded in standard Odoo architecture so it upgrades cleanly and hands over cleanly. Models subclass models.Model; access is governed by ir.model.access.csv plus record rules so a payout clerk can import and match but only an accountant can post; the UI is delivered as Odoo list/form views (XML, with OWL components where an interactive matching board earns it) filtered by gateway, status, and payout date; a QWeb report renders a per-batch reconciliation statement suitable for the auditor. An automated action (or ir.cron) can poll a gateway API on a schedule and pre-stage the next settlement batch before your team even logs in, and every model is reachable over Odoo's XML-RPC/JSON-RPC API if you want to trigger imports from an external ETL job. It runs on Community or Enterprise — we flag any point where an Enterprise-only accounting feature (like the bank-sync connectors or advanced analytic distribution) changes the integration, and give you a Community-safe path where one exists.

Because this is build-to-order, nothing is a shrink-wrapped download. We start from a short scoping call to inventory your exact gateways, their settlement file formats, your chart of accounts and fee/FX account mapping, and your Odoo version (17.0, 18.0, or 19.0) and edition. We build against a copy of your configuration, validate the matching rules on real historical settlement files during UAT on a staging database, and only then install to production behind a tested rollback plan. Typical delivery is 2 to 4 weeks from confirmed scope, depending on how many gateways and edge cases (partial payouts, reserves, multi-currency, negative settlements) are in play. You receive the full source, the git repository, documentation, and a post-go-live support window — no black boxes, no per-seat lock-in.
