Free Odoo 19 Community Modules: What We Publish and How to Install Them

Odoo 19 Community runs sales, purchasing, inventory and invoicing well, but finance, HR and operations teams soon reach its edges. There is no trial balance, no payroll, nothing to stop one person processing a refund unsupervised and no register that warns you before a trade license expires. Our free Odoo 19 Community modules were written to close gaps like these, one module for each problem.

Odoo Enterprise covers several of the same areas with its own apps, including Accounting, Payroll, Documents and Approvals, and when you need most of them it is usually the shorter road. This guide is for teams that run Community or are weighing it up. It explains why we publish the modules, tours them by business area, flags the ones that cannot sit beside Enterprise apps and walks through installation on Odoo.sh and on your own server.

Why We Publish Free Odoo Modules

Community implementations tend to run into the same handful of gaps. Rebuilding the same fix for each client would be slow and hard to maintain, so we write it once as a proper module, test it on Odoo 19 Community and publish it on the official Odoo App Store, where anyone can download it.

Three principles run through all of them. Each module starts from a clearly described problem. Each keeps the Odoo core standard and adds its capability as an ordinary add-on, with its own access groups where it needs them, which keeps future upgrades possible. And each module page says what we tested on Odoo 19 Community and, where it applies, what we have not tested yet.

Publishing in the open also lets you judge our engineering before you hire us. If a module solves your problem on its own, install it and carry on. If you want help, the engineers who wrote it can configure it for you.

A Tour of Our Free Odoo 19 Community Modules by Area

The catalog on our OdooStar modules page is grouped the same way as this tour. Each module name below links to its own page, with features, dependencies, workflow and screenshots.

Accounting

SBS Account Community adds the reports and controls an accountant expects: general ledger, trial balance, partner ledger, aged balances, day, cash and bank books, a journals audit and a tax report. It also brings fixed-asset depreciation, budgets, customer follow-ups, fiscal-year lock dates, recurring payments and per-user journal restrictions. Our guide to the accounting reports Odoo Community leaves out covers each one.

SBS View Products in Journal Entries adds an optional Product/Service column to the Journal Items tab, so an accountant can see which product a line came from without opening the source invoice or bill.

Sales and Returns

SBS Auto Return puts identified returns, unidentified returns and exchanges on one record, and posts nothing to stock or the ledger until a manager finalizes it. SBS Auto Delivery/Invoice turns a counter sale into one confirmation: delivery validated, invoice posted and payment registered, as a single amount, a credit sale or a split across journals.

SBS Sales Discount Amount lets salespeople type a discount in money, with the percentage kept in step. SBS Multi UoM, named for multiple units of measure, sells one product by the unit, box or pallet, with a price for each packaging unit and stock kept in base units. Small bridge modules connect SBS Auto Return to these, so discounts and packing units carry through to the credit note, and to SBS Auto Delivery/Invoice, so an exchange's replacement order is not invoiced twice.

HR and Payroll

SBS HR Payroll gives Community a payroll app: salary rules, structures, payslips and batches, with the journal entry posted when a payslip is confirmed. A manual correction keeps the rule's own figure beside it, and a confirmed payslip is reversed rather than deleted.

SBS Employee Master Extension adds the details many HR teams keep in a spreadsheet, such as family details, passport and other identity numbers, nominees, bank details, qualifications and employment history. They sit behind three access tiers, with a read-only My Profile view for staff.

Inventory and Purchasing

SBS Employee Purchase Requisition lets staff request goods, requires two different approvers, then has Odoo create one purchase order per vendor and an internal transfer for stockroom items. SBS PO Bill Button restores the one-click Create Bill button that Odoo 19 removed from the purchase order form, using Odoo's own billing logic.

Documents and Projects

SBS Document Management provides workspaces with access levels, business documents that work out their own reminder dates before they expire, document requests, letter templates with approval and expiring share links. SBS Project Extension keeps delivery facts on the project record: team, client contact, technical details, maintenance periods, financials, review sessions and task timers.

Security and Administration

SBS Menu Manager hides menus per user and locks create, update, delete, archive and export per model, enforced on the server rather than only on screen, and adds a read-only role for accounts that should look but never touch, such as an auditor. SBS Password Manager stores business credentials encrypted, with the key held outside the database, an identity check before every reveal and an audit log nobody can edit.

SBS Automatic Database Backup schedules backups to local or remote storage without ever storing the master password, and records a SHA-256 checksum, a digital fingerprint of the file, for every run. SBS Data Remove lets an administrator permanently clear test transactions for the active company in one all-or-nothing run, keeping master data intact, so take a verified backup before every run.

Healthcare

SBS Pharmacy Management adds medicine details to the ordinary product form, such as active ingredient, strength, manufacturer and dispensing mode, plus a daily sales report that splits takings into cash, card, credit, insurance and branch.

Community plus Modules, or Odoo Enterprise?

Before installing anything, settle the edition. Odoo Enterprise is a paid, per-user subscription that adds apps Community does not include, along with Odoo's own support and upgrade service. Where the gap you face is covered by an Enterprise app, compare the two routes honestly.

As a rule of thumb, when you need several of these Enterprise apps at once, or Odoo's upgrade service matters to you, Enterprise is usually the better investment. When one or two specific gaps stand between you and a working system, Community plus the relevant free modules is often enough. Our guide to choosing between Odoo Enterprise and Community goes deeper.

Modules That Cannot Sit beside Enterprise Apps

SBS Account Community and SBS HR Payroll are deliberately Community-only, because they replace Enterprise apps rather than extend them:

• SBS Account Community excludes the Enterprise accounting modules account_accountant, account_asset, account_budget, account_followup and account_reports, so it cannot be installed alongside Enterprise Accounting.
• SBS HR Payroll excludes hr_payroll, so it cannot be installed alongside Enterprise Payroll, and Enterprise Payroll cannot be installed alongside it.

The other modules declare no conflicts with Enterprise apps. They are built and tested on Odoo 19 Community, though, so if you run Enterprise, try any of them on a staging copy before production. SBS Project Extension, for example, notes that Enterprise ships its own task timer, so expect two timers on Enterprise.
