Finance teams running Odoo constantly hit the same wall: the accounting reports are excellent on screen but stubborn on export. Odoo's General Ledger, Trial Balance, Partner Ledger, Aged Receivable/Payable, and P&L / Balance Sheet render beautifully in the web client and export cleanly to PDF, but the built-in "Export to XLSX" produces flat, single-sheet dumps that lose the hierarchy, the account groupings, the comparative columns, and every bit of formatting your controller actually needs. So the month-end reality is a chain of manual copy-paste into a spreadsheet, hand-built pivot tables, and formulas that break the moment the chart of accounts changes. In Community edition several of the richer dynamic financial reports aren't even present, so the gap is wider still.

Accounting Excel Reports is a build-to-order Odoo module ECOSIRE designs and develops to close that gap. We add a reporting layer on top of account.move.line and the account.report engine (or a custom TransientModel wizard where the engine isn't available) that composes native accounting data into structured, multi-tab .xlsx workbooks. The export is generated server-side with a streaming library such as xlsxwriter, so it handles large datasets without blocking the worker, and every workbook carries proper column headers, frozen panes, grouped/outlined rows that mirror your account hierarchy, number formats that respect each company's currency and decimal precision, subtotal and grand-total formulas (live =SUM() cells, not baked values), and a cover sheet stamping the company, fiscal period, filters, and generation timestamp for audit traceability.

Technically, the module ships as a clean addon with its own __manifest__.py declaring the dependency on account, ORM models and a wizard for the report parameters (date range, journals, analytic accounts, comparison periods, target moves posted vs. all), QWeb/OWL views for the launch dialog, and a controller endpoint that returns the binary attachment. Access is governed by ir.model.access.csv plus record rules so users only export the companies and journals they're entitled to, and the whole thing is multi-company aware. Where you need reports delivered rather than clicked, we wire an ir.cron automated action and the email layer to push a scheduled workbook to a mailing list, or expose the generator over the XML-RPC / JSON-RPC API so an external BI pipeline can pull the same formatted export programmatically. Every report definition is data-driven, so adding a new statement layout later is configuration, not a rewrite.

Because this is made-to-order, delivery follows a short, predictable path: a scoping call to confirm exactly which reports, columns, groupings, and formats you need; a fixed written quote; then build on a branch, UAT on a staging copy of your database, and a supervised go-live on production with a rollback plan. Typical delivery is 2-4 weeks from confirmed scope, depending on how many report layouts and integrations are in play. Pricing starts from $249 (indicative, single-company base scope); additional report layouts, multi-company consolidation, deep localization of statement formats, scheduled/emailed delivery, and external BI/API integrations increase the quoted scope.
