Service

Hire the outcome, not another tool.

Most AI products give your team something new to run. Here the work is done for you, and AI agents do it behind the scenes.

AI software

Paperhound service

  • Handled end to end
  • No setup project
  • Paperhound verifies each form and follows up with the vendor on any mismatch, so you do not have to
  • You pay only for completed W‑9s

The problem

W‑9s are easy to ask for and hard to finish.

01

Vendors do not respond

The request sits in their inbox while your team sends reminders by hand.

02

Mismatches surface late

The name and tax ID on the form do not match, and you find out at the worst time.

03

The work lands on your team

Someone reads every form, chases every vendor and keys the result into the vendor master.

How it works

From vendor list to finished forms, in three steps.

Paperhound builds the AI agents that chase and orchestrate every vendor. You do not need to manage or worry about any of it.

  1. 1

    Connect your books

    Paperhound’s agents find the vendors you paid this year and which of them have no current W‑9 on file.

  2. 2

    The agents collect

    The agents email each vendor and follow up regularly. Where there is a phone number, they call. You can see the status of every vendor at any time.

  3. 3

    Verify and post

    The agents verify the tax ID and name, resolve any mismatch directly with the vendor, and post the completed form into your books.

Pricing

Pay per completed W‑9.

A W‑9 counts as completed when it is verified and posted into your books. A vendor who never responds costs you nothing.

Fit

Built for bookkeepers and finance teams.

Who this is for

Bookkeepers and accountants who handle vendor paperwork for clients, and finance teams that want the W‑9 chase off their plate before year-end.

Not a fit if

  • You want software to run yourself.
  • You already have a verified W‑9 on file for every vendor.

FAQ

Frequently asked questions

What counts as a completed W-9?

The form is collected from the vendor, the tax ID and name are verified, and the form is posted into your books. Anything short of that costs you nothing.

Is this software we have to learn?

No. Paperhound is a service. Paperhound needs read access to your books. AI agents run the work and deliver the finished W-9s. You do not log in to anything or configure anything.

What if a vendor never responds?

The agent keeps following up: emails on a regular schedule, and phone calls where there is a number. You see the status of every vendor. You pay only when the W-9 is completed.

How do you verify a W-9?

Paperhound checks the tax ID and the vendor's legal name against the form. When something does not match, Paperhound follows up with the vendor directly, so your team does not have to.

Is our vendor data safe?

Paperhound's agents connect directly to your email and your accounting system. They run in the USA on AWS-hosted infrastructure and use models such as ChatGPT and Claude.

Which accounting systems do you work with?

QuickBooks Online, Xero, NetSuite, Sage Intacct, Oracle Fusion, Zoho and Workday.

When should we start?

W-9s are easiest to collect before January. Starting in the fall leaves time for follow-ups and for fixing mismatches.
