Sound familiar?

Your sales numbers never seem to agree.

Facebook says one thing. Your bank says another. Your spreadsheet says something else. So you make budget decisions on a gut feeling and hope you backed the right ad.

Same week. Same ads. Three different answers.

The ad platforms grade their own homework

Facebook and the other ad platforms count their own sales, and they count generously. The tool spending your money should not be the one deciding how well it did.

Tracking quietly stops working

Phone privacy updates and disappearing cookies broke the old way of tracking sales. Most tools fill the gaps with guesses you have no way to check.

You are renting your own numbers

You pay every month for reports that live in someone else's system. The day you leave, all your history leaves with them.

A better way

One dashboard that tells you the truth.

Hollow watches your funnel from your own website, then matches every visitor to the real money landing in Stripe and PayPal and the real amount you spent on ads. The result is one honest picture of what is working, in an account that belongs to you.

No guesswork

Every sale tells you how sure it is.

Some sales tie back to a customer by their own email, rock solid. Others are a best estimate. Hollow puts a plain-language label on each one, right where you see it, so you always know what is proven and what is a guess.

How it works

Up and running in minutes, not weeks.

1

Add one line to your site

Copy a small snippet into your website or funnel. It works everywhere, including GoHighLevel, and even catches leads on pages that other trackers miss.

2

Connect your accounts

Link Stripe, PayPal, and Facebook in a few clicks, plus GoHighLevel and Kit if you use them. Everything is kept safe and private.

3

Watch it fill in

Sales show up the moment they happen, ad spend updates on its own, and every sale is tied back to the ad that earned it.

Questions

Good questions, straight answers.

Do I have to switch away from my CRM or ad accounts?

No. Hollow reads from the tools you already use and lines everything up. It becomes your single source of truth for where sales come from, without ever changing anything in your other tools.

How long does setup take?

Minutes. Add the snippet, connect your accounts, and a friendly step-by-step guide walks you through the rest, showing only the tools you actually use.

Does it work with GoHighLevel?

Yes, including funnels where people click a button and get sent to another page, which is exactly where most trackers lose the lead.

What about all the privacy and cookie changes?

Hollow runs on your own website instead of relying on the third-party tracking those changes broke. That is the whole point.

Do you own or sell my data?

Never. Your data is yours, in your own account. Export it whenever you like, and keep it if you ever decide to leave.

Does it only work with Facebook?

Sales tracking works no matter where your traffic comes from. Facebook ad-spend syncing is live today, with Google and TikTok on the way.

Monthly or yearly?

Either, and you can cancel anytime. Paying yearly works out to two months free compared with paying monthly.

Pricing

Simple pricing. Everything included.

One flat price for the whole platform: every report, unlimited dashboards, and your entire team. No per-sale fees, ever.
