Running payroll in one place and booking it in another is where most finance teams lose hours and trust. Payslips get computed in HR, then someone re-keys totals into the general ledger — or worse, posts a single lump-sum journal that hides which department, project, or expense line each cost belongs to. Odoo's core payroll (an Enterprise app) computes payslips well, but out of the box the bridge to accounting is thin: salary-rule-to-account mappings are shallow, multi-company and analytic distribution get awkward, employer-side contributions and accruals often aren't posted the way your accountant expects, and reconciling the payroll clearing account at month-end becomes a manual chase. That is exactly where a native, made-to-order integration earns its keep.

We build a Payroll Accounting module that makes the payslip the single source of truth for both HR and finance. Technically, it extends hr.payslip and the salary-rule model so each rule carries a configurable debit/credit account, an optional analytic distribution, and a partner (for statutory bodies and pension funds). On confirmation, a compute/@api.depends-driven layer builds a fully balanced account.move grouped the way you choose — per employee, per department, or consolidated per run — with employer contributions and provisions (leave, gratuity, bonus accruals) posted to the correct liability and expense accounts. Everything is governed by ir.model.access.csv plus record rules so HR sees payslips while only finance can post or reset the resulting moves. QWeb reports give you a payroll-to-GL reconciliation statement and a per-account breakdown; automated actions can schedule the posting and flag any run whose journal entry fails to balance before it reaches the ledger. Where you need it to talk to external systems — a bank file, a statutory portal, or a data-warehouse — we expose the numbers cleanly over Odoo's XML-RPC/JSON-RPC API.

Because payroll is jurisdiction-specific, we design the salary-rule and account mapping around your actual chart of accounts and local requirements rather than a generic template, and we account for Community vs Enterprise differences up front (core payroll computation is an Enterprise app; we make the accounting layer fit whichever edition and localization you run). The module ships with sensible defaults you can edit from the UI — no code change needed to remap an account or add a new contribution — and every version is delivered for your target release across Odoo 17.0, 18.0, and 19.0.

Delivery is build-to-order: it starts with a short scoping call to confirm your salary rules, chart of accounts, analytic needs, multi-company setup, and any statutory posting rules. We then build and configure the module on a staging database, run UAT with your real payslip data, and hand over installable source, a git repo, and documentation. Typical delivery is 2–4 weeks from confirmed scope, and it is a service we build and support — not an existing download you install unattended. Pricing starts from $249 (indicative, single-company base scope); multi-company posting, deep localization/statutory mappings, complex analytic distribution, or migration of historical payroll data increases the quoted scope.
