You didn't start a business to become a bill collector.
Biz Critical's Invoice Chasing agent connects to the books you already use — QuickBooks, Xero, or FreshBooks — and follows every invoice past its due date. A friendly nudge, then a firmer one, then a final notice. Sent under your name, in your tone. You hear from it only when a client actually needs you.
→ Live and chasing invoices in 5 business days, or the setup fee is on us.It was never a data problem.
QuickBooks, Xero, and FreshBooks already tell you exactly what's overdue. What they don't do is the awkward part — actually chasing your clients for money. So it happens late, inconsistently, or not at all.
By the time you send a reminder, 30 or 60 days have gone by, and the client has moved on mentally. Every one of those days is cash sitting in someone else's account instead of yours.
Four things happen automatically. One thing happens only when it should.
Watches your books
Synced to QuickBooks, Xero, or FreshBooks the moment an invoice goes out. Nothing new for you to check.
Tracks days overdue
Every invoice is scored against your cadence — Day 7, Day 14, Day 30+ — and nothing gets chased twice.
Writes in your voice
Each message is drafted for that client, that invoice, that tier — friendly first, firmer next, final if it comes to that.
Sends under your name
Email from your own inbox, SMS at the final tier. Every send and every reply logged.
A dispute, a VIP client, a promise to pay — anything that isn't routine skips the agent and lands straight in your inbox. It hands off; it never decides for you.
Live in 5 business days.

Ten questions to score your own invoice follow-up before you automate it. No email required to read it — the opt-in below is only if you want us to follow up.
Most owners who've read this far already know the answer to one or two of these — the checklist just makes it concrete enough to act on.
- Do you know your average DSO (Days Sales Outstanding) off the top of your head?
- Can you pull an aging report — 0–30 / 31–60 / 61–90+ — in under two minutes?
- Does every invoice show clear terms: due date, late fee, accepted methods?
- Is there a standing cadence (Day 7 / 14 / 30), or does follow-up happen "whenever"?
- Does the reminder go out even when you're slammed, or does it get skipped?
- Do you have a firm-but-polite second reminder ready, or write it from scratch each time?
- Is there a clear point where a slow payer gets a phone call instead of another email?
- Do you track which clients are chronically slow, so terms can change before the next job?
- Is every reminder sent logged somewhere, or does it live only in your memory?
- If a client disputes an invoice, do you hear about it the same day?
