What it catches

Ad budgets that ran overComing soon

Yesterday's spend on every daily Google Ads budget, compared with the budget. When one runs more than 20% over, you hear about it the next morning.

Invoices that went unpaid

QuickBooks invoices that are past their due date and still unpaid, gathered into one email. Each is flagged when it goes overdue, and once more at 30 days.

Questions

Can you change my ads or invoices?

No. We only read: budgets and spend from Google Ads, unpaid invoices from QuickBooks. We never change a campaign, budget or invoice.

Is my data safe?

Access to your accounts is stored encrypted, and when you cancel it's revoked and deleted. We don't sell your data or use it for advertising.

Will you email me every day?

Only when something needs attention. Each problem is flagged once, not every morning; overdue invoices get one reminder at 30 days. You'll also get one email when you connect, with what the first check found, and during a free trial, a short all-clear if a week goes by quietly.

What's the difference between Basic and Pro?

Basic watches one service: QuickBooks. Pro, which watches Google Ads and QuickBooks together, opens once Google Ads alerts do. You can switch plans anytime from your subscription settings.

Is there a free trial?

Yes: 14 days free. We take a card at signup so alerts carry on without a gap, and the first charge is when the trial ends. Cancel before then and you pay nothing.

How do I cancel?

Anytime, on your own: every email we send links to your subscription settings, or manage it here. You keep the service until the end of the month you paid for.

Which tools do you support?

QuickBooks Online now; Google Ads soon.
