Built-In Sales Tax Rules vs Avalara or TaxJar: Which to Use

At a glance

Side-by-side summary on six criteria teams usually evaluate first. Pricing and packaging change over time — verify current plans on each vendor site before you buy.

Where the built-in rules are enough

For Canada, the Canada pack covers GST, HST, QST and the provincial sales taxes by province, with return lines for the GST34, QST and PST returns. Most Canadian businesses do not need a provider for that.

For a US business registered in one or a few states, the US pack installs those states with their rates and taxability rules, and you import the city, county and district rates for the ZIPs you ship to. Charge only where registered keeps tax off states where you have no nexus.

The rules are effective-dated, a rule you edit is kept when the pack is reinstalled, and the Tax Simulator shows which rule applied to a line and why.

Where a provider earns its place

Once you are registered in many states, keeping local rates current by ZIP becomes the larger task. Biznsbook does not ship official local rate tables, so every change is a row you import.

A provider works out state, county, city and district tax from the address. Biznsbook posts each of those on its own components, so the return lines, the dashboard and the settlement journal look the same as with rules.

Posted sale invoices are recorded with the provider every 15 minutes or on Sync now, recorded again if their tax changes, and voided when cancelled, so the provider’s own filing reports see them.

What stays on the rules either way

Purchases and tax-inclusive prices are priced by the jurisdiction rules even with a provider connected. Use tax on purchase bills is worked out from the rules at the receiving warehouse.

Sale returns and POS sales are not sent to the provider yet. POS sales are taxed at the store.

If the provider cannot be reached, the sale is taxed with the rules and flagged, unless you untick Fall back to jurisdiction rules. In that case the sale cannot be saved until the provider answers.

What to check before switching

Switching to a provider needs at least one active rule, a provider, and its credentials, plus the account id and company code for Avalara. Install the US pack for your states first, so the fallback and purchases have rules.

Start in Sandbox, post and cancel a few invoices, and read provider reconciliation: Recorded, Voided, Failed with the error, or Pending. Failed invoices are retried up to 8 times, and Record again retries one.

Documents already posted keep their tax when you change method. Only new documents use the provider.

What neither option does

Biznsbook does not file returns with a tax authority or register you in a state. It prepares the return lines and exports them as PDF or Excel.

Neither method is tax advice. The Canada and US packs are drafts until a tax adviser reviews them, and the starting provider tax codes for item categories should be checked against the provider’s catalogue.

Pricing honesty

Biznsbook publishes Starter at $19, Pro at $39 and Business at $89 a month, and Accounting and Taxation are included in every plan. Connecting Avalara AvaTax or TaxJar needs no extra Biznsbook module, but it does need your own account with the provider, priced by the provider. Check /pricing.html and the provider’s own site before you decide. This page does not quote provider prices.

Who should choose each

Choose Biznsbook if…

• You sell in Canada and need GST, HST, QST and PST by province with GST34, QST and PST return lines.
• You are a US business registered in one or a few states and can maintain local rates for the ZIPs you ship to.
• You want no second account, and you are happy to review rate changes yourself or with an adviser.
• You want the simulator to show exactly which rule applied to each line.

Choose Avalara or TaxJar if…

• You are registered in many US states and local rate maintenance is becoming a job of its own.
• You want the provider’s address-based rates and its own filing reports alongside Biznsbook.
