Poland Accounting Localization Base

This is a made-to-order Odoo localization base that ECOSIRE builds for your specific company after a scoping call — not an existing download you install today. We deliver a proper Polish chart of accounts template modeled on the Zespol 0-8 account classes, a complete VAT tax set (23/8/5/0%, reverse charge, exempt, and NP/not-subject), and sales and purchase VAT registers driven off account.move and account.tax so registers reconcile to your ledger by construction rather than by hand. Technically it is a clean Odoo module: a __manifest__.py declaring dependencies on account, base_vat, and base_iban; account-template and tax-template data loaded through l10n-style chart templates; new register models built on models.Model with @api.depends computes rolling up tax amounts; QWeb PDF/XLSX reports for the periodic registers; and access controlled through ir.model.access.csv plus record rules so the registers respect Odoo's multi-company and journal-security boundaries.

The whitelist and split-payment logic is where the localization earns its keep. We wire a service against the MF wykaz podatnikow API to verify a NIP's active-VAT status and its registered microaccount / bank accounts, storing the check result and timestamp on the partner so your AP team has an audit trail before releasing a payment. Split payment is applied at the account.payment level — flagging in-scope invoices, computing the VAT portion routed to the dedicated VAT account, and reflecting the mechanizm podzielonej platnosci on the payment. We add NIP/REGON validation with GUS company lookup to auto-fill contact data, a nota korygujaca (corrective note) document type, fiscal positions for EU/OSS scenarios, and bank statement import mappings for common Polish formats (MT940 / Elixir). All of it is exposed to your other systems through Odoo's standard XML-RPC / JSON-RPC API, and it is built to run on Community or Enterprise across Odoo 17.0, 18.0, and 19.0 (Enterprise adds richer accounting reporting; the core localization behaves identically on Community).

Delivery is build-to-order. After a short scoping call we confirm the exact account structure, tax edge cases, and integrations you need, then build, test on a staging copy of your database, and hand over installable source plus a git repository. Typical delivery is 2-4 weeks from confirmed scope. Pricing starts from $299 (indicative, single-company base scope); additional legal entities, deeper localization coverage (custom register layouts, extra document types), external integrations, and historical data migration volume increase the quoted scope. You receive a fixed quote after the scoping call — never a surprise.
