Striking back against overpriced tax software
Paying thousands just to calculate what you owe?
Tired of hidden fees & annual price increases?
Afraid of being locked into a long, complex, and expensive contract?
Description:
TaxAvenger is a no-nonsense, do-it-yourself tax solution built for companies that are tired of paying thousands for empty promises and bloated services. Most tax platforms pad their pricing with vague guarantees like audit protection - but when the time comes, they are nowhere to be found, buried behind loopholes and disclaimers.
TaxAvenger does nnt pretend to be your lawyer or CPA. It does not promise to fight the IRS on your behalf. What it does is give you the same tools that big companies use behind the scenes - a direct API integration, real-time tax rates, addons for nexus tracking and exemption certificate management (only if you need them), and basic tax reports - all inside your Odoo database. No middleman. No hidden fees. No smoke and mirrors.
How it works:
- Purchase a GEO-Level subscription from ZipTax at a fraction of the price of leading Tax Services
- Configure all TaxAvenger settings in your Odoo database
- TaxAvenger will parse the results from ZipTax and automatically apply tax rates to your Sales Orders & Invoices
- File your own taxes using Odoos Tax Reporting
Simple. Fast. Affordable.
Key Features:
- Connects to the ZipTax API to fetch live US Sales Tax rates.
- Applies tax rates on Sales Orders and Invoices.
- Supports Origin or Destination FOB logic (storefront vs. shipping)
- Exemption Certificate Management system (Sold as an add-on)
- Define Categories for taxable/exempt product types per state
- Export basic sales tax reports (Excel download)
- Seamless integration with Odoo fiscal positions and tax logic.
- Nexus Tracking system (Sold as an add-on)
Important
This Odoo app does not include a ZipTax API Subscription.
You must purchase and maintain a valid GEO-Level API subscription separately from
https://www.zip.tax/
A GEO-Level subscription is Required. The CORE-Level subscription will not work with this module!
Without a valid API key, this module will not be able to fetch sales tax rates.

Download Excel reports that break-down your tax activity by a user-specified date range and state selection.

by County, as well as by County/City.
Keep an eye out in the future for additional state-specific TaxAvenger Report Addons!
