For people who hate sales tax compliance.
You shouldn’t have to manage your tax provider. Pursor reads your shop, your marketplaces, your ledger and your bank; files and pays every return; books it; reconciles the payment. Nobody at your company uploads a file, keys a journal or answers a notice. You see one page, and it agrees with your books.
Ten minutes, nothing filed, nothing changed. No card, no call.
Pursor reads your shop, your marketplaces, your ledger and your bank on its own. There is no export to run, no monthly file to send and no journal to key.
Every return is booked in your ledger when it files and matched to the bank line when it clears. Your sales tax accounts agree at month-end without anyone touching them.
When a state issues a notice, it comes to us. We read it, fix it and file the response. You hear about it only if we need something from you, which is rare.
The free check
Before anything changes, see where you stand. The check reads what you collected, what your provider filed, and what the marketplaces say they remitted, and shows you where they disagree.
A Shopify export and your provider’s liability files. The finding is yours whether or not you move.
Collected
By state, by month
From your orders, with who remitted each.
Filed
What went to the state
From your provider’s own liability files.
The difference
With its cause
Filed twice, over-filed, a return missing, a state to register in.
Who runs it

Pursor was founded by Andrew Playford, the CFO of a successful, mid-sized consumer goods brand. Frustrated not only by the cost of outsourced compliance, but also by the amount of time his team still had to spend to manage those providers and fix their mistakes.
The returns are prepared by the system from your own data and go out when they agree with your books and your bank. The people here make judgment calls: a notice, an audit, a state that changed its rules. They are not there to ask you questions a machine could have answered.
Why it doesn’t go wrong
Four records are read side by side every month. Where they agree, the return files on time without you. Where they don’t, Pursor finds the cause and fixes it before the due date, so the return still files on time and nothing in your books is left unexplained.
Collected
On the sale
Every order, by state and month, from Shopify and the marketplaces, with who remits on each.
Booked
In the ledger
Pursor posts the sales tax accrual into your ledger every month, state by state, and keeps the liability report that agrees with it.
Filed
On the return
The return as it will go to the state, gross sales, the marketplace’s share taken off, your own tax.
Paid
Out of the bank
The state’s debit on your own account, matched to the return the day it lands. Pursor never holds your money.
At month-end
Your balance sheet shows what you owe and where. One liability report per state, agreeing with the ledger and with what was filed, is there for the close, your auditor or your bank, without anyone building a spreadsheet.
Who it is for
If you sell on any of them, you have returns due in most states, even where the marketplace collects the tax for you. Those are the returns that go wrong, and most of them are nil returns a machine should be filing.
Pursor reads Shopify and each marketplace directly, with your ledger and your bank beside them. BigCommerce, WooCommerce and SaaS on Stripe are next, and VAT for the brands that sell into the UK, Europe and Canada.

Questions people type
Does Pursor calculate tax at my Shopify checkout?
No. Shopify Tax keeps calculating at checkout, and the marketplaces calculate their own. Pursor reads what was collected, checks it, builds the return and files it. For a Fulfil, BigCommerce or custom checkout, Pursor’s own rate lookup is available by API.
My Shopify automated filing is ending. What happens in January?
Shopify files your returns for sales through December 31, 2026, and stops. From the January return you file yourself or use a service. Run the check first; it tells you which states you are registered in and what has been filed there.
Amazon remits my tax. Do I still file?
In most states where you are registered, yes: a return reporting the sales with the marketplace’s share taken off, often to a nil liability. Those are the returns that get filed wrong, and the ones a machine should file.
What happens if a return does not tie?
It does not file silently. Pursor shows the four figures, which one disagrees and by how much, finds the cause and fixes it before the due date. The return still files on time, and nothing in your books is left unexplained.
Do I have to move my accounting system?
No. Pursor reads the ledger you already run and writes the sales tax accrual into it, by state. Nothing moves and nobody changes where they work.
About ten minutes. The finding is yours whether or not you move.
