Sobre este producto
The GCC Withholding Tax (WHT) Engine is a build-to-order Odoo 17/18/19 module that ECOSIRE designs, develops, installs and supports for your finance team. It brings withholding-tax obligations that Odoo core simply does not handle out of the box into your Accounting workflow: configurable rate masters per WHT category, automatic deduction at vendor-bill and payment time, vendor certificate generation, and a dedicated WHT-payable liability ledger you can reconcile and remit to the tax authority.
Withholding tax in the GCC, wider MENA and many African and South-Asian jurisdictions is a structural gap in standard Odoo. Native account.tax handles VAT-style taxes that add to an invoice line, but WHT is fundamentally different — it is deducted from what you pay the vendor and it creates a liability you owe the government. Bolting that logic onto core tax objects with spreadsheets and manual journal entries is slow, error-prone and impossible to audit at scale. This module solves it properly at the ORM level.
Because this is engineered specifically for your regime, ECOSIRE grounds the build in your actual withholding rules: your rate categories (services, royalties, rent, technical fees, dividends, cross-border payments), your thresholds and exemptions, your certificate format, and the ledger and reporting shape your accountants and auditors expect. We ship real Odoo — a proper module with __manifest__.py, models.Model classes, @api.depends computed fields, ir.model.access.csv plus record rules, XML/OWL views, and QWeb PDF certificates — not brittle Studio patches.
This is not an existing apps.odoo.com download and there is no instant download. After purchase, ECOSIRE scopes your specific WHT rules, builds and installs the module on your Odoo 17, 18 or 19 instance (Community or Enterprise), migrates or configures your data, trains your team, and supports you through a defined warranty window. Typical delivery is one working week depending on the number of categories, jurisdictions and certificate formats in scope.
Technically, the engine introduces a wht.category master (rate, tax authority code, thresholds, exemption logic, income type), a wht.tax.line that ties each withholding to its source account.move / account.payment, and compute methods with @api.depends that derive the net amount payable to the vendor and the amount withheld. Deductions post to a dedicated WHT-payable liability account through Odoo's standard journal-entry engine, so nothing sits outside your general ledger. Automated actions can flag bills that cross a category threshold, and every certificate is a versioned QWeb report tied to the underlying moves for a clean audit trail. XML-RPC / JSON-RPC endpoints let your other systems read WHT figures programmatically.

¿Para quién es esto?
GCC / MENA Finance Manager
Owns vendor payments and tax compliance for a company with withholding obligations. Needs deductions applied automatically, certificates issued to vendors, and a clean liability figure to remit — without manual journals or spreadsheets.
Group Accountant in an Emerging Market
Handles multi-entity, multi-currency payables across jurisdictions with different WHT rates and thresholds. Needs per-category, per-authority reporting that reconciles back to the general ledger for auditors.
Tax / Compliance Officer
Responsible for correct withholding rates, threshold triggers, treaty exemptions and audit-ready evidence. Needs configurable categories, exemption reason codes, and a traceable link from every certificate to its source transactions.
Accounts Payable Clerk
Processes vendor bills and payments daily. Needs the net-payable amount computed correctly on-screen and threshold or missing-certificate flags surfaced before posting, so nothing is caught at period close.

Preguntas frecuentes sobre GCC Withholding Tax (WHT) Engine
How long does delivery take and what happens after I buy?
This is a build-to-order module, not an instant download. After purchase, ECOSIRE runs a scoping session to capture your WHT categories, rates, thresholds, exemptions and certificate format, then develops, installs and tests the module on your Odoo instance. Typical delivery is one working week depending on the number of categories, jurisdictions and certificate formats in scope. You get a schedule with milestones up front.
What support and updates are included?
Every build includes a defined post-go-live warranty window covering bug fixes and configuration adjustments, plus training for your finance team. Beyond the warranty we offer ongoing support and maintenance retainers, including compatibility updates when you upgrade Odoo versions and adjustments when a tax authority changes its WHT rates or certificate rules. We hand over the source so you are never locked out of your own module.
Does this work with Odoo Community, and which versions are supported?
Yes. The module is built on standard framework objects (account.move, account.payment, QWeb, ir.model.access.csv, record rules) and works on both Odoo Community and Enterprise. We support Odoo 17, 18 and 19, and target the specific version your instance runs so the build matches your environment exactly.
Can it handle our specific country's withholding rules and certificate format?
Yes — that is the point of building it to order. During scoping we configure your rate categories (services, royalties, rent, technical fees, dividends, cross-border payments), your threshold and exemption logic, and design the QWeb certificate to match what your regulator and vendors expect. It works across GCC, wider MENA, African and South-Asian regimes; we tailor it to yours rather than shipping a fixed template.
How is the withheld amount posted and reported in accounting?
Withholding posts through Odoo's standard journal-entry engine to a dedicated WHT-payable liability account, so nothing sits outside your general ledger. The vendor receives the net amount, the withheld portion becomes a liability you owe the authority, and the liability/reconciliation reports show amounts withheld, certified, remitted and outstanding per period, category and authority — all reconcilable and audit-ready.
Can other systems read the WHT data?
Yes. WHT categories, withholding lines and certificate data are exposed through Odoo's XML-RPC and JSON-RPC APIs, so external tax-filing, reporting or BI tools can pull the figures programmatically. We can also scope custom endpoints or scheduled exports as part of the build if you need a specific integration.
Why not just use Odoo's native tax feature or an off-the-shelf app?
Native account.tax adds tax to an invoice; WHT deducts from what you pay a vendor and creates a liability you owe the government — a fundamentally different flow that core Odoo does not model. Generic apps.odoo.com modules rarely match GCC/emerging-market thresholds, exemptions and certificate formats, and you cannot get them adapted. A build-to-order module encodes your exact rules and is supported by the team that built it.

GCC Withholding Tax (WHT) Engine
Build-to-order Odoo module that auto-computes, deducts and reports withholding tax on vendor bills and payments across GCC and emerging markets.
- Configurable WHT rate masters (wht.category) per income type — services, royalties, rent, technical fees, dividends and cross-border payments — each with its own rate, tax-authority code and effective dates
- Automatic WHT computation on vendor bills (account.move) using @api.depends compute methods that derive the withheld amount and the net amount payable to the vendor
- Deduction applied at payment time (account.payment) as well as at bill confirmation, so partial payments withhold proportionally and reconciliation stays clean
- Threshold handling — withholding only triggers once cumulative vendor or category spend crosses a configurable minimum, matching real regulatory thresholds
