FloorSync / Compared
FloorSync vs Admaxxer for Stripe revenue, Meta Ads and GA4
Admaxxer is a marketing analytics and ad-ops platform: attribution reports, ad account dashboards, server-side tracking and an AI agent that works on your campaigns. FloorSync does one narrower job: it takes each Stripe event your server gets and sends the sales to Meta and GA4, with a ledger of what arrived.
Pick Admaxxer if you want attribution reports, MER and LTV views, or an agent that manages Meta and Google campaigns. Pick FloorSync if you want your Stripe sales in Meta and GA4 without a script on your site or a Stripe key, at a flat $29 a month.
| FloorSync | Admaxxer | |
|---|---|---|
| Price | $29 a month per business, flat, no event limit. 7 days free. | Starter $9 (15k tracked events a month), Growth $29 (100k), Pro $79 (750k), Scale $199 (3M), Enterprise $499 (15M). Events are hard-capped. 7-day trial on Starter and Growth. |
| What you add | Nothing on your website. One call in your Stripe webhook handler. | Its tracking script on your site (script tag, npm, or plugins for many site builders). |
| Stripe access | No Stripe key: your server forwards events it has already verified. | A restricted Stripe key (rk_…) pasted into Admaxxer, plus a webhook. |
| Where sales go | Meta Conversions API and GA4. | Meta Conversions API (a CAPI match rate on every plan). Connects Meta, Google, TikTok and Klaviyo ad accounts. |
| Renewals | Sent as purchases matched to the first buyer; counted apart in the ledger. | Renewals, trials and cancellations come in from Stripe for its revenue reports. |
| Before you pay | A dry run: the exact Meta and GA4 payloads and GA4’s validation answer, nothing sent. Try it below. | 7-day trial on your real site. |
| For your agent | agent-install.md, a ledger API, OpenAPI, llms.txt and an MCP endpoint; no model key needed. | An MCP server for Claude, ChatGPT, Cursor, Codex and more, and its own Maxxer agent, which runs on your own Anthropic, OpenAI or GLM key. |
| Reports | One small ledger: revenue, sales, renewals, refunds, what Meta and GA4 accepted, revenue per ad dollar. | Revenue attribution, UTM grid, MER, cohort LTV, creative grid; more on higher plans. |
| Support | Email. | Email; priority support and a success manager on higher plans. |

Where Admaxxer wins
- Attribution reports and dashboards across Meta, Google, TikTok and Klaviyo.
- An agent that can work on your campaigns, not just read results.
- Cheaper to start ($9 a month), if you stay under 15,000 events.
- Seats for a team.
Where FloorSync wins
- No Stripe key to hand over, and nothing on your website.
- Sends to GA4 as well as Meta.
- Flat price: no event cap to hit as you grow.
- Your own agent reads the ledger; no model key to supply.
What the FloorSync side looks like
One call in the webhook handler you already have, after Stripe’s signature check. Python, from the docs:
import hashlib, os, requests
# payload: the raw body bytes you passed to stripe.Webhook.construct_event(...)
try:
requests.post('https://floorsync.towers.app/api/v1/events/stripe', data=payload, timeout=10, headers={
'Content-Type': 'application/json',
'X-Floor-Key': os.environ['FLOORSYNC_KEY'],
'x-amz-content-sha256': hashlib.sha256(payload).hexdigest(),
})
except requests.RequestException:
pass
Try it on a renewal
What Meta and GA4 would get from a Stripe renewal, worked out in your browser. Nothing is sent.
