What did you collect this period, at which rates, and does it agree with your own books? That's the whole question a sales-tax return starts with, and this plugin answers it from the invoices you already raised. Gridzu itself is free; the suite of four plugins is what you pay for.

Pick a period and every invoice you raised is grouped by the rate it charged: taxable sales, tax collected, exempt sales counted apart. Voided invoices are skipped and named; an undated one is named too rather than guessed into a period.
Each line recomputes taxable sales times the rate and compares it with what was actually charged. Rounding passes; a hand-edited figure is flagged — before you copy it onto a form, not after.
With the Accounting plugin, the worksheet stands next to the ledger's own liability account: held at the start, collected, paid over, still holding. When the two disagree, it says so and says why — usually invoices not posted yet.
A table of your places and their combined rates — state plus city plus county as one number. Yours to keep current, visible on every invoice that used one, and zero is a real rate: five states have no sales tax at all.
One click writes the worksheet down as a filing, so next quarter can see what this one said. Paying it over posts through the same door as everything else — the liability comes down, the bank comes down, and it can't post twice.
Taxes reads the invoices the CRM or Accounting already raised. It keeps no duplicate list to drift out of step — its own tables are just your rates and your filings.
It is the worksheet half of sales tax. What you collected, by rate, over any period, with every figure traceable to the invoices behind it and checked against your own ledger.
It is not a filing service, and it computes no returns. Gridzu totals what you charged and shows the working; it submits nothing to any state or agency, and nothing here is tax advice. The return — the form, the deadline, the e-file — is yours or your accountant's.
It is not a rate service either. The rates are yours, kept by you. Software that quietly “knows” every county's rate is software that is quietly wrong somewhere, and sales tax is the wrong place to find that out.
for the whole suite — Taxes comes with the CRM, accounting and payroll, not sold on its own. Gridzu itself is free.
You buy it inside Gridzu, not here — install the app, sign in, and Taxes is a button on the toolbar waiting to be switched on. All four land on your account the moment you pay, with nothing to enter twice.
