What this page is. Client-proof collection tools bought by freelancers and local service businesses — testimonial request emails, permission checklists, feedback forms, review-request wording, NFC review cards, and a review-request automation. This page is the after of a finished project: collecting proof, protecting it, and making the ask. It is not client onboarding: no intake or kickoff workflows — those live on our Client Onboarding page. The NFC cards are review-collection tools, never social content packs. The n8n kit is an email workflow, never an SEO or ranking product. The trades prompts are a wording toolkit, never a business-income play. Permission checklists are a tracking habit — the seller says so explicitly, and this page repeats it: they are not legal advice.

The ask, not the outcome. These kits sell asking systems — request emails, checklists, card taps, timed reminders — never review counts. Nothing here can promise reviews, and this page never claims otherwise. The anchor's own author says it best: no workflow can make a client leave a review.

About ratings. None of the six products below shows any ratings — not one. Don't read social proof into this page: it is "verified live and in stock," not a bestsellers list. Artifact detail (checklist items, prompt counts, workflow node counts, card quantities) does the selling.

Sellers appear twice. TinyOps Foundry sells both the free starter checklist (step 1) and the paid full workflow (step 3) — they sit in separate sections as starter vs. system, never adjacent as one upsell ad. kadenwprints sells both the supplier link (step 2) and the physical cards (step 5) — one supply story, not scattered.

Format notes. Step 5 is a physical product — shipping times and costs apply, not instant download. Step 6 needs n8n and some technical comfort; its compliance note is about sending automated follow-up emails responsibly, not legal advice. Step 4 needs access to a chat AI (ChatGPT/Claude).

Prices. Prices are set by each seller on Gumroad and can change; prices below were served in USD on a US fetch and may localize for non-US readers.

STEP 1 · THE FREE ENTRY · PERMISSION-FIRST STARTER

Free Testimonial Permission Checklist

$0.00 · TinyOps Foundry · no ratings shown

The permission-first entry: a Markdown checklist, a PDF convenience copy, a CSV tracker, and usage notes for recording testimonial permission before you publish anything — exact quote approved, name/company/title approved, logo and screenshots approved, NDA checked. The rule it enforces is simple: never publish a testimonial you can't prove you were allowed to use. Honest framing: no ratings; this is the free starter, not the system — the paid pack (step 3, same seller) contains its own permission checklist plus the full asking workflow, so we keep them in separate sections and never adjacent. Not legal advice: it's a tracking habit. Lowest setup bar on the ladder: free, download and start logging.

STEP 2 · THE $2.99 SUPPLY LINK · ORDER THE CARDS

NFC Review Cards Supplier

$2.99 · kadenwprints · no ratings shown

The supply-link slot: a vendor access link for ordering NFC tap-to-review cards in 25/50/150/500 quantities — the source behind the physical cards in step 5. Position: if you want the physical cards, this is where they come from. Honest framing: no ratings; and the source copy flirts with reseller framing — this page presents it strictly as the supplier for the cards, never as a business opportunity, and never income talk. Same seller as step 5: one supply story, kept together. Physical products mean real shipping times and costs — factor that in.

The asking systems

The complete workflows for when the free starter isn't enough: the full testimonial + mini case-study operating system, and the review-request wording kit for people who work with their hands.

STEP 3 · THE $3.49 FULL WORKFLOW · TESTIMONIALS + MINI CASE STUDIES

Testimonial & Mini Case Study Pack for Freelancers

$3.49 · TinyOps Foundry · no ratings shown

The full workflow slot: request emails, a client feedback form, a mini case-study template, a permission checklist, a tracker CSV, and a 15-minute setup guide. Position: the operating system for asking clearly, making it easy for the client to say yes, and not publishing anything without explicit approval. Honest framing: no ratings; same seller as the free starter — step 1 is the free checklist, this is the complete paid system, kept in separate sections so the page never reads as one upsell ad. Permission checklist included, but the seller's own disclaimer stands: not legal advice. Price note: the live listing serves $3.49 — we carry the live figure.

STEP 4 · THE $27 TRADES SLOT · REVIEW-REQUEST WORDING

The Trades Business AI Prompt Toolkit

$27.00 · Trades AI Pro · no ratings shown

The trades-buyer slot: 36 done-for-you prompts across 6 trades (contractor, plumber, electrician, roofer, landscaper, cleaning) and 6 categories — one category is Google-review requests, alongside negative-review replies, lead follow-up, estimate reminders, Facebook posts, and seasonal promotions. Honest framing: no ratings; and we name the fit exactly — only 1 of the 6 categories is review-focused, so this is a review-request + review-reply prompt set inside a trades marketing toolkit, never a complete review system. Format note: needs access to a chat AI (ChatGPT/Claude). Kept as a wording toolkit — never income or business-growth framing.

STEP 5 · THE $30 PHYSICAL TOUCHPOINT · NFC REVIEW CARDS

NFC Review Cards (25, 50, 150, 500)

$30.00 · kadenwprints · no ratings shown

The physical-touchpoint slot: NFC tap-to-review cards in 25, 50, 150, and 500 quantity tiers — the customer taps their phone and lands on your Google review page. Position: the card you hand a happy customer before they leave. Honest framing: no ratings; same seller as the step-2 supplier link — one supply story, not scattered. And this is a physical product: shipping times and costs apply, not instant download. The source mentions reseller framing; this page keeps it simple — it's the supplier for the cards you hand out, nothing more.

STEP 6 · THE ANCHOR · $49.00 · THE AUTOMATED ASK

n8n Google Review Automation Kit — Request + Smart Reminder (Client-Ready)

$49.00 · Vestra · no ratings shown

The anchor and the most on-niche product on this page: an importable n8n workflow (14 nodes) that sends review requests at the right moment, checks whether the client already reviewed, and sends a smart reminder without nagging — plus FR/EN setup guides, a one-page client checklist, and a compliance note on sending automated follow-up emails responsibly. Position: the ask happens consistently, at the right moment, without ever asking twice. Honest framing: no ratings; technical pick — you need n8n and some comfort with it. And the author's own honesty is this page's baseline, repeated verbatim in spirit: it doesn't promise you'll get more reviews. No workflow can. The compliance note is about responsible sending — never legal advice.

Why this page exists

NINE's free tier stays free because of pages like this one. Every product above was verified live with a visible price and picked for the ask-protect-amplify ladder: a free testimonial-permission checklist, a $2.99 NFC card supplier link, a $3.49 testimonial + mini case-study workflow, a $27 trades review-request prompt toolkit, $30 physical NFC review cards, and a $49 n8n review-request automation kit — the ladder from "never publish a testimonial you can't prove you were allowed to use" to "the ask happens consistently, at the right moment, without ever asking twice." Kept distinct from our Client Onboarding page (no intake or kickoff workflows here — these are proof-collection tools), and the NFC cards are review-collection tools, never social content packs. None of the six products shows any ratings, so this page is "verifiably live and in stock," not a bestsellers list. Nothing here promises review counts — these are asking systems. Nothing here is a paid placement.
