CONCEPT PREVIEWOpen record

The question to test

What supports your next
100 exempt sales?

And which questions does your current system already identify? A useful pilot separates previously unidentified gaps from alerts you already have.

01 Right legal entityThe buyer and the named entity align. 02 Right jurisdictionThe evidence applies to this sale’s state. 03 Right periodSale, receipt and actual validity are distinct. 04 Complete sourceThe required fields and source can be inspected.

A source-linked example

A document on file
is a starting point.

TX-091 has a candidate certificate. CE-21 names a different buyer entity and state. The record remains held while the reviewer inspects the exact evidence.

The accountant also rejects an imported generic expiry inference. Correcting that inference does not clear the entity or jurisdiction mismatch.

Five independent proposed workflows

One evidence job.
Five ways to begin.

Choose the repeat task your team needs to test. Each workflow has its own inputs, owner and proposed output.

01 / PROPOSED WORKFLOW

Transaction linkage

Trace an exempt transaction to the certificate proposed to support it. Keep the entity, state, date and source in the same review.

Before the conversation

A few useful answers.

The starting scope is narrow by design. The proposed pilot tests evidence value, not demo polish.

Is ExemptLink an operating product?

ExemptLink is a research-stage concept. This website demonstrates proposed workflows using fictional records. No production integrations, tax determinations or customer outreach are available.

How is this different from an existing certificate manager?

The category already has substantial overlap. A permissioned pilot must compare findings with your actual ECM and tax-engine alerts. The hypothesis is incremental review value, not a novel document vault.

Which taxes are in scope?

The starting scope is US sales-tax exemption evidence. VAT and income-tax substantiation are outside the current scope.

What data would a pilot need?

Start with a scoped conversation. A later agreed pilot needs permissioned historical sales and evidence through an approved transfer mechanism. Do not upload or paste records into this website.

Are the prices current offers?

No. USD 2,000 for a bounded pilot and USD 600–2,000/month for a later entity/state cluster are hypothetical test prices, subject to scope.

Who approves outreach or corrections?

Your named tax owner retains authority. Reviewing a sample does not grant permission to contact customers; scripts and recipients require separate approval.
