These Terms of Service ("Terms") govern your access to and use of the Sefro sales tax rate and calculation API and related services (the "Service"), operated by Call The IT Dude LLC, doing business as Sefro ("Sefro", "we", "us"). By creating an account, using an API key, or otherwise accessing the Service, you ("Customer", "you") agree to these Terms.
Sefro provides U.S. sales and use tax rate data and calculations through an API. Rate data is compiled from state Departments of Revenue and other public sources and is provided to help you estimate applicable sales tax.
The rates, calculations, and other content returned by the Service are provided for general informational purposes only and do not constitute tax, accounting, or legal advice. Tax laws, rates, jurisdictional boundaries, product taxability, and exemptions change frequently. Consult a qualified tax professional regarding your specific obligations.
Sales tax is imposed by taxing jurisdictions (states, counties, cities, and
special districts), not by ZIP code. A single ZIP code can span more than one taxing
jurisdiction and therefore more than one rate, and ZIP boundaries change over time.
Any result keyed to a ZIP code is an estimate. Each response includes a
rate_type field indicating whether the result is
"authoritative" (sourced directly from a state Department of Revenue or
official rate file) or "estimated" (an approximation derived from base
geographic data). Even an authoritative rate reflects the dominant jurisdiction for a
location and may not equal the rate at a specific street address.
You are solely responsible for (a) determining the correct tax for each transaction, including the correct jurisdiction, product taxability, and exemptions; (b) collecting, reporting, and remitting all taxes to the appropriate authorities; and (c) providing accurate inputs to the Service. Sefro is a software tool; it is not your agent, is not the taxpayer, and does not assume your tax obligations.
THE SERVICE AND ALL RATE DATA ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, COMPLETENESS, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE IS UNINTERRUPTED, ERROR-FREE, OR THAT ANY RATE OR CALCULATION IS ACCURATE, CURRENT, OR COMPLETE.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, SEFRO WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY UNCOLLECTED OR OVER-COLLECTED TAX, PENALTIES, INTEREST, FINES, OR LOST PROFITS. SEFRO'S TOTAL AGGREGATE LIABILITY WILL NOT EXCEED THE AMOUNTS YOU PAID TO SEFRO FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.
You will defend, indemnify, and hold harmless Sefro from claims, liabilities, damages, and expenses arising out of your use of the Service, your tax collection or remittance, or your breach of these Terms.
You will not exceed your plan's limits, resell or redistribute the raw rate data as a standalone competing dataset, reverse engineer the Service, or use it unlawfully. API keys are confidential and you are responsible for activity under your keys.
Paid plans are billed as described at signup. Free trials convert to a paid plan unless canceled before the trial ends. Fees are non-refundable except as required by law.
Any written accuracy commitment we offer for a specific paid plan applies only on the terms stated there, is limited to the stated remedy and cap, and applies only where you used the Service correctly with a complete, validated street address. It does not cover the underlying tax itself, results from estimated data, or your configuration errors. Absent such a commitment, Sections 5 and 6 govern.
We may modify the Service or these Terms; material changes will be posted here with an updated date. We may suspend or terminate access for breach or non-payment.
These Terms are governed by the laws of the State of Washington, without regard to conflict-of-laws rules. Any dispute arising under these Terms shall be brought exclusively in the state or federal courts located in Washington, and both parties consent to their jurisdiction and venue.
