For independent bookkeepers and service businesses using QuickBooks Online
Overdue QuickBooks invoices? Get an email.
We check your QuickBooks once a day. You get an email when something needs attention.
See what's overdue right now. No card; we attempt to revoke access straight after. How we handle your data
No card. No CashWatchdog account. Intuit will show its standard broad accounting permission because it does not offer a narrower one; CashWatchdog only reads the overdue-invoice information needed for this check, then attempts to revoke access immediately. See exactly how the free check handles your data.

Bookkeepers: spot late invoices between client reviews
Watch up to 10 QuickBooks companies with one Bookkeeper subscription. When new invoices need attention, one email shows which company and customer to follow up with. You or the owner handles the follow-up. We never contact their customers.

What it catches
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.

Know when an invoice needs a person
QuickBooks Online already provides customer payment reminders and accounts receivable reports. Use those tools. CashWatchdog adds a short alert to you or your bookkeeper when an invoice first goes overdue, so you can decide whether a phone call or personal follow-up is warranted. It does not email your customers or run collections for you. Compare with QuickBooks.
Best fit: businesses that invoice on payment terms but cannot check overdue balances every morning. If most sales are paid on delivery, or you already monitor receivables daily, CashWatchdog may not add much.
Before you connect: QuickBooks asks for broad accounting access; Intuit does not offer a narrower permission for this connection. CashWatchdog uses it only to read the invoice and company information needed for alerts, never to edit your books. Tokens are encrypted and access can be revoked. We are not yet listed in the QuickBooks App Store. Review our access and security details.

Questions
When do daily checks run?
Checks are scheduled daily at 13:00 UTC: 9 AM Eastern during daylight saving time and 8 AM Eastern during standard time. This fixed schedule does not follow your local timezone. Email can arrive after the check finishes. We also try the first check when you connect; your account page shows the latest check status.
Doesn't QuickBooks already track overdue invoices?
Yes. QuickBooks Online has invoice lists, accounts receivable reports and optional customer payment reminders. Those are worth using first. CashWatchdog doesn't replace them: it sends you or your bookkeeper a heads-up when an invoice becomes overdue, without requiring a daily report check. See when it adds value.
Will CashWatchdog send reminders or collect payments for me?
No. CashWatchdog doesn't contact customers, follow up on unpaid balances or manage collections. It shows you which new overdue invoices may need attention; you decide whether to call, email, or use your existing QuickBooks reminder process.
Which businesses is it best for?
Businesses that invoice customers on payment terms and don't already check receivables every morning. If your customers mostly pay at delivery, or you already review overdue invoices daily, you probably don't need another alert.
Can you change my invoices?
No. We only read your unpaid invoices from QuickBooks. We never change an invoice, and we never send anything to your customers.
What permission does QuickBooks ask for?
Intuit's consent screen requests broad accounting access because it has no narrower permission for this connection. CashWatchdog uses that access to read overdue invoices and the company name, not change the books. Connection keys are encrypted, and you can disconnect from QuickBooks or from your CashWatchdog account. We aren't listed in the QuickBooks App Store yet. Read exactly what we access, store and delete.
Is my data safe?
We don't store copies of invoices in our database. We keep encrypted connection keys and minimal account data; alert emails do include customer names and balances, and our mail provider processes sent emails. You can revoke access at any time. See our security details and current limitations.
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 the plans?
Basic watches one service: QuickBooks. Pro, which watches Google Ads and QuickBooks together, opens once Google Ads alerts do. Bookkeeper watches up to 10 QuickBooks companies, such as your clients', with one email covering all of them. You can switch plans anytime from your subscription settings.
I look after several companies' books. Which plan?
Bookkeeper. It watches up to 10 QuickBooks companies from one account, where Basic watches one. You connect each company with its own Intuit sign-in, picking a different company each time: use the QuickBooks link in your welcome email, or Add another company on your account page, where you can also remove one. On a morning when something new has gone overdue, you get one email covering every company, and each invoice in it names the company it's from. If one company's connection stops working, the others are still checked and we email you to reconnect that one.
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 or year you paid for.
Which tools do you support?
QuickBooks Online now; Google Ads soon.
