The free check

Three things in, your finding out. About ten minutes.

Nothing is filed and nothing changes. The check reads what you collected, what your provider filed, and what the marketplaces say they remitted, and shows you where they disagree.

Read-only, once you connect it. Or Shopify’s Taxes finance export instead.

Their liability files are read next: the State Liability Summary and Return Detail exports from Avalara, TaxJar, Numeral and Zamp.

3. Marketplaces you sell on

Each one is read for what it remitted itself, so a double payment can be proven, not guessed.

No card, no call. The finding is yours either way. Or write to contact@pursor.com.

What comes back

One page: by state and month, what you collected, what was filed, and the difference with its cause. Filed twice, over-filed, a return missing, a state you should be registered in.

Where a marketplace’s own record proves it remitted the tax, the line says so. Where Pursor cannot read a record yet, the line says “not checked” rather than a figure.

You can take the finding to your provider or to the state’s refund process yourself. If you want Pursor to file from here, it is $50 a return, from the next return, state by state.

What to do with each line is written under it on the full page: the refund route for the state, or the registration to make. Nothing here has been sent anywhere.
