How to vet and onboard vendors as Small Finance Teams

Ops & SupplyFor Small Finance Teams2 apps11 steps~22 min to set up

Your vendor onboarding process is a mess of email threads, shared Google Drive folders, and a QuickBooks vendor list nobody trusts. A new SaaS vendor needs a W-9, a COI, an NDA, and AP setup — and you're chasing all four in separate tabs. Vetting means manually cross-referencing a vendor's invoice history in QuickBooks against what procurement says they approved, then checking a Stripe payout to confirm payment terms match. When a vendor renews or a contract auto-rolls, you find out because an invoice shows up that doesn't match anything in your records. With three people covering AP, AR, close, and board prep, no one has time to build a real process — so you wing it every time.

Outcome

What you'll set up

A vendor intake and vetting workflow that pulls existing payment history from QuickBooks and Stripe automatically, so you're looking at real spend data — not what someone said they'd spend — before you approve a new vendor.
A contract and obligation tracker that surfaces upcoming renewals, expiration dates, and approval status in one view, not buried in a Drive folder no one remembers to check.
An AP onboarding checklist app that walks each new vendor through W-9 collection, COI review, NDA sign-off, and NetSuite or QuickBooks vendor record creation as a structured workflow — not a chain of Slack DMs.
The Starch recipe

Apps, data, and prompts

The combination of Starch apps, the data sources they pull from, and the prompts you use to drive them.

Data sources & config

Starch syncs your QuickBooks data on a schedule (vendors, bills, payments, invoices) and your NetSuite data on a schedule (invoices, expenses, journal entries) — both as direct scheduled-sync connections. Stripe is also synced on a schedule for payout and charge history. For vendors who require contract signatures, Starch automates document workflows through your browser — no separate e-signature API needed. Contract Lifecycle Management is currently in development (coming soon — request beta access); in the meantime, the Project Management app handles the intake and review workflow.

Prompts to copy
Build me a vendor onboarding tracker that shows every new vendor request with status fields for W-9 received, COI reviewed, NDA signed, and AP record created. Pull in our QuickBooks vendor list so I can see if they already exist as a vendor before we start the process.
Create a contract renewal dashboard that shows vendor name, contract value, renewal date, owner, and whether we've reviewed auto-renewal terms. Send me a Slack message 60 days before any contract renews.
Show me all vendor payments from QuickBooks in the last 12 months where the vendor doesn't have a signed contract on file — sort by total spend descending.

Walkthrough

Step-by-step

1 Connect QuickBooks or NetSuite as a scheduled-sync provider so Starch has a live, auto-refreshing vendor list, bill history, and payment records — no manual exports.
2 Connect Stripe as a scheduled-sync provider so you can cross-reference vendor payouts against what's in the ledger, and flag any vendor you're paying via Stripe who isn't in your AP system.
3 Open the Project Management app and describe your vendor onboarding checklist: W-9 collection, COI review, NDA routing, AP record creation, and payment terms confirmation. Starch builds the workflow as a structured tracker with status columns and assignee fields.
4 Ask Starch to pull your existing QuickBooks vendor list into the tracker and flag any vendor marked active who has no bill in the last 180 days — these are your first audit candidates.
5 For each new vendor request, create a project card: type the vendor name, expected annual spend, and category. Starch assigns the intake checklist and notifies the right person on your team.
6 Use browser automation to pull vendor registration or compliance details from any web-based portal your vendors use — no API needed. Starch navigates, reads the relevant fields, and populates your tracker.
7 Build a contract obligation view: ask Starch to show all active vendor contracts with renewal date, contract value, auto-renewal clause (yes/no), and days until renewal. Set a Slack alert for anything renewing in the next 60 days.
8 For vetting, ask Starch to summarize 12-month payment history from QuickBooks for any vendor under review — total paid, invoice count, average days to pay, and any payment disputes. Use this before approving a rate increase or expanding scope.
9 When a vendor is fully onboarded (all checklist items complete), ask Starch to create the NetSuite or QuickBooks vendor record from the intake data — name, address, payment terms, tax ID — without re-keying it.
10 Run a monthly vendor audit: ask Starch to show every vendor where total spend in QuickBooks exceeds $10,000 and no contract is on file. Export the list, assign owners, and track remediation inside the same Project Management app.
11 When the Contract Lifecycle Management app launches (coming soon — request beta access now), migrate your active contracts into it for AI-assisted renewal drafting, clause tracking, and e-signature routing.

Worked example

Q1 2026 Vendor Audit — 14 Vendors, $340K in Uncontracted Spend

Sample numbers from a real run
Cloud infrastructure vendors (AWS resellers, Datadog MSP)142,000
Professional services — recruiting, legal, consulting98,000
SaaS renewals auto-billed to card (no PO)67,000
Facilities and office vendors33,000

In Q1, the finance team asked Starch to cross-reference 12 months of QuickBooks bill payments against the contract folder in Google Drive. Starch pulled all 214 vendor records from QuickBooks (scheduled sync), matched vendor names against the Drive file list (browser automation — no Drive API configured), and surfaced 14 vendors with combined payments over $340K who had no signed contract on file. The largest exposure was $142K to three cloud infrastructure vendors — all billed monthly, all on auto-renew, none with negotiated SLAs. Starch built a remediation tracker in the Project Management app with one task per vendor: owner assigned, contract template linked, deadline set. The finance team went from 'we think we have contracts somewhere' to a prioritized list with responsible owners in one afternoon. When the Contract Lifecycle Management app launches, the same vendor list will feed directly into the CLM for renewal drafting and e-signature collection.

Measurement

How you'll know it's working

Days to complete vendor onboarding (W-9 through AP record creation) — target under 5 business days
Percentage of active vendors with a signed contract on file — track monthly, target 95%+
Total AP spend with uncontracted vendors — should trend to zero after first audit cycle
Contract renewals reviewed at least 30 days before auto-renewal date — tracked per quarter
Duplicate or ghost vendor rate in QuickBooks — number of vendors with no bill in 12 months but still marked active
Comparison

What this replaces

The other ways teams handle this today, and how the Starch version compares.

Google Drive + email + manual QuickBooks exports
Zero incremental cost, but the process lives in someone's head and breaks every time that person is out or leaves the company.
Coupa or Zip (procure-to-pay platforms)
Purpose-built for vendor intake and PO workflows, but priced and configured for enterprise procurement teams — not a 3-person finance function at a 200-person company.
DocuSign + HubSpot for contract tracking
Handles e-signatures and CRM-style deal tracking well, but doesn't connect to your actual AP spend in QuickBooks or NetSuite, so vetting still requires manual cross-referencing.
Airtable + Zapier for a DIY tracker
Flexible and affordable, but you build and maintain every automation yourself — and none of them sync directly to your live QuickBooks or NetSuite data without additional configuration work.
On Starch RECOMMENDED

One platform — contract lifecycle management, project management all running on connected data. Setup in plain English; numbers stay current via scheduled syncs and live agent queries.

FAQ

Frequently asked questions

We use NetSuite, not QuickBooks. Does Starch connect to NetSuite for vendor and AP data?
Yes. Starch syncs your NetSuite data on a schedule — invoices, expenses, journal entries, and balance sheet data are all available. You can build your vendor tracker and audit workflows on top of live NetSuite data the same way you would with QuickBooks.
The Contract Lifecycle Management app is listed as coming soon. What can I actually use today?
The Project Management app handles the intake and review workflow today — vendor onboarding checklists, status tracking, assignee management, and Slack alerts for upcoming renewals. You can describe your exact process to Starch and it builds the workflow. The CLM app (coming soon) will add AI-assisted contract drafting, a clause library, and e-signature routing on top of that foundation. You can request beta access now to get notified when it launches.
Can Starch pull W-9s or certificates of insurance from vendors automatically?
If your vendors submit documents through a web portal you can log into, Starch can automate that process through your browser — no API needed. For email-based document collection, Starch connects to Gmail or Outlook (both are scheduled-sync providers) and can surface attachments matching a vendor name. Starch won't automatically parse a PDF W-9 for tax ID accuracy today, but it can flag which vendors haven't submitted one and track that status in your onboarding workflow.
Is Starch SOC 2 certified? We have to tell our own compliance team what tools handle vendor data.
Starch is not SOC 2 Type II certified today. That's worth knowing before you route sensitive vendor documents like W-9s or contracts through it. Many small finance teams use Starch for the workflow tracking and QuickBooks/NetSuite data surfacing, while keeping raw document storage in a Drive folder or their existing document management tool.
Our QuickBooks has 400+ vendors and some are clearly duplicates or inactive. Can Starch help clean that up?
Yes. Ask Starch to pull your full vendor list from QuickBooks (synced on a schedule), filter for vendors with no bill in the last 12 months, and show you duplicates by name similarity. You can review the list and decide which to merge or inactivate. Starch won't write changes back to QuickBooks directly — you'd make the edits in QuickBooks — but it gives you the prioritized list to work from instead of manually scrolling a 400-row vendor screen.
We don't have a formal procurement process — vendor requests come in through Slack. Can Starch handle that?
Starch connects to Slack (available as a connection for custom apps). You can build an intake workflow where a Slack message in a designated channel triggers a vendor onboarding task in the Project Management app — automatically creating the checklist, assigning an owner, and logging the request. Describe the flow to Starch and it builds the automation.
