Most tax engines answer a question the law didn't ask.

Sales tax is one return on the list.

StateWashington's state returns: the combined excise return to the Department of Revenue, and the returns other state agencies require, each with its own forms and rules.

CitiesCity returns: B&O tax returns and each city's own taxes and quirks, Seattle's included.

Manage, prepare, approve, automate.

Manage

Every client, every obligation, on one screen.

The dashboard shows each client's filing calendar, open obligations and current status across the Washington returns they file. What is due, what is ready, what needs a decision.

The client book: a client expanded to its three companies.

Prepare

Every return is built from the statute up.

Sundry analyzes the business activity of your clients and customers to decide what returns to file and what exemptions apply. Every transaction is checked. Nothing is sampled.

An exempt sale without proof is a taxable sale. Sundry asks your client's customers for their proof, reads it and checks it before the return.

If our determination or a proof we verified is wrong and your client underpays as a result, we refund what you paid us for that return. See the Sundry Guarantee. Override a determination and that one is your call.

How exemption proof works

The September month-end close: census audit, calculate, worksheet, e-sign and filed.

Approve

What they collected. What they owe. The difference.

The Sundry Worksheet puts all three side by side, by client, by company, by authority, by return. Drill in as far as you need to. Nothing goes forward until you say so.

How determination works

Automate

Your client signs off on the Sundry Worksheet.

The Sundry Worksheet is the endpoint: your client signs off on their liability. Sundry covers Washington state and local returns: the state combined excise return, city returns: B&O tax returns and each city's own taxes.

There's no training course. When you need to know something, ask Sal.

Grow the practice without growing the staff.

Many firms turn down state and local work, or take it on and lose money. The returns are low-value individually and expensive to do by hand, and the expertise needed to do them well does not scale across a small firm. Sundry does the hand work: the determination, the return and the proof behind every exempt sale.

This work has been unprofitable because it was manual.

That is the part that changes.

Grow the practice, not the staff.

Take on more clients' state and local returns with the people you already have.

This work lost money because it was manual.

The census, the proof chase and the worksheet were the hours that made state and local returns unprofitable. Sundry does those hours; your firm reviews and decides.
