"Show me vendors with TIN mismatches in the last 30 days."
Agents that work your vendor base while you sleep.
Every VendorKeep tenant ships with a roster of named watchers. They run continuously, surface what needs your eye, and never act without approval on anything irreversible.
W-9 freshness
Watches every contractor for missing or stale W-9s. Sends reminders on a smart cadence; escalates after silence.
"Reminder #2 for fresh W-9 (3y stale) — Heritage Office Supply"
TIN watcher
Validates TINs against IRS records in real time. Opens a triage item the moment a B-Notice arrives.
"B-Notice received from IRS — Granite Peak Audits"
Renewal watcher
Scans every contract for renewals. Surfaces 30/60/90-day windows with negotiation context attached.
"12 contracts in 60-day window, 4 in 7-day window"
Cap watcher
Watches per-vendor spend caps. Flags any vendor approaching or exceeding their YTD limit before the next invoice posts.
"YTD $36.8k of $40k cap (92%) — Bluebird Studio"
Spend anomaly
Detects unusual spending patterns vendor-by-vendor. Calls out month-over-month spikes, classification changes, and missing invoices.
"MoM spend +312% (avg $4k → $16k) — Mosaic Marketing"
Duplicate vendor
Finds vendor records that look like duplicates. Compares names, EIN roots, addresses, and bank info to flag merge candidates.
"94% name similarity, same EIN root — Acme Sign / Acme Signs LLC"
Every action shows the input, the reasoning, the output — and waits for your approval on anything irreversible. No black-box AI.

Sync from Campfire, Rillet, or Ramp — or upload a CSV. Vendor records, payments, and GL data flow into one tenant scoped to your EIN.
Watchers go to work
W-9 freshness starts onboarding contractors. TIN watcher validates in real time. Renewal watcher tracks every contract. They run continuously, surfacing what matters.
You stay in control
Every action shows input → reasoning → output → approval. Your AI of choice queries the same data, with the same controls.
One platform. No more stitching tools together.
Vendor onboarding & verification
Contractors get a single link to complete their W-9, sign their contract, and submit their info. Real-time IRS TIN matching catches mismatches before they cost you. The W-9 freshness and TIN watcher run in the background — no chasing required.
- W-9 + contract e-signature in one onboarding link
- Real-time IRS TIN matching with automatic B-Notice handling
- Configurable workflows per vendor type — COIs, MSAs, banking
Contract management
Templates, redlines, signing flow, and a renewals queue with auto-renew controls. The Renewal watcher surfaces every contract approaching expiration with negotiation context attached — so you renegotiate on your terms, not theirs.
- Reusable contract templates with clause libraries
- Side-by-side redline diff between proposed and current
- Renewal alerts at 30, 60, and 90 days
Filing & reporting
Year-round filing readiness, not a January scramble. 1099-NEC, 1099-MISC, and the full series — federal and state. Pull payment data automatically from Campfire, Rillet, and Ramp. When the year closes, filing is one click because the data is already clean.
- Federal + state filing for the full 1099 series
- Continuous filing-readiness scoring across the year
- Audit-ready exports — every action, every approval

AI clients (via MCP)
Every vendor onboarded.
Every contract tracked.
Every 1099 filed.
Built-in agents do the work. Your AI of choice drives it.
Bank-grade controls. Built in.
Vendor PII is sensitive. Agent access is powerful. We treat both like the audit risk they are.
Tax IDs in a separate vault
TINs and EINs live in a KMS-encrypted PII vault — never in the main database, never in logs.
PII never crosses the AI boundary
Raw TINs stay in the vault. AI clients only ever see masked values like ***-**-6789.
Three-tier action gating
Read tools are unrestricted. Mutating tools require an idempotency key. Destructive tools require human consent.
Per-agent OAuth scopes
Tenant admins decide what every agent can do. Tighter than your role permission matrix is always allowed; wider isn't.
Paired audit rows on every mutation
Every agent action is logged twice — invoked and outcome — with arg fingerprint to prevent replay.
Tenant isolation at the row level
Multi-tenancy enforced in the database, scoped to your EIN. Cross-tenant probes return "not found."

"I spent years as a controller and CFO chasing W-9s, stitching together compliance tools, and scrambling every January. VendorKeep is what I wished existed — one platform that handles vendor compliance year-round, with named agents doing the work and your favorite AI driving the workflow.
