Revenue protection

Catch the errors that
slip through every day.

Every order that arrives by email but never gets invoiced is revenue you've already earned — and never collected. Every wrong item, wrong customer, or missing field is a problem waiting to happen. Invoice Auditor catches all of it automatically.

Know which overdue invoices to chase first. Fix incomplete invoices before your customer calls asking where their order is.

Built for cold-calling
A simple queue your sales team can work through: see the lead, reveal the contact, call, mark it done, move to the next.
For your sales team

Your invoices already know
who your best customers are.

Invoice Auditor doesn't just protect revenue — it helps you find more of it. Your sales team gets a ready-made pipeline of new businesses that look like the customers you already sell to best, with contact details you can reveal when you are ready to call.

No separate lead-gen tool to learn, no list to import. It's already running on the customer data you have.

10 free leads every month, included
Move inventory

Your invoices know who buys
what you already have.

Invoice Auditor reads every line of every invoice you have ever sent — so when stock sits still, it already knows who to call and writes the email that moves it.

📦

Move Inventory

Pick any model sitting in your warehouse and see every customer who has bought it before, with their numbers next to their names. Not a report — a call list.

✉️

Weekly Sales Ad

Picks the stock that has stopped moving, prices it to move, and drafts the sales email with your name at the bottom. You read it, you send it.

Detection

What gets flagged automatically

Orders never invoiced
Email orders with no matching QuickBooks invoice — revenue you've earned but never billed.
Wrong item or quantity
Catches when the item, condition, or quantity on the invoice doesn't match what was ordered.
Duplicate invoices
Same customer, same amount, a few days apart — likely invoiced twice. Flagged before you chase a payment that already came in.
Unit price mismatch
Detects when the price per item on the invoice differs from what was agreed in the email.
Incomplete invoice fields
Missing tracking numbers, PO numbers, due dates, and billing emails — flagged before your customer calls asking where their order is.
Overdue invoice prioritization
Overdue invoices scored by risk so you know which ones are worth chasing and in what order.
Who it's for

If you invoice from email and want to grow, this is for you

Any business where orders come in by email, invoices are created in QuickBooks, and someone is responsible for bringing in new customers.

Distributors & wholesalers
High order volume, changing prices, multiple SKUs — a wrong item or missing invoice adds up fast. Catch every error, and find more customers like your best ones.
Product sellers
Wrong item, wrong variant, wrong condition — catch picking errors before the invoice goes out, while your sales team works a list of new leads.
Sales teams
Stop cold-calling from stale lists. Work a pipeline of real businesses that already look like your best customers, with phone numbers ready.
Bookkeepers
Audit QuickBooks invoices across multiple clients automatically. Catch errors your clients don't even know they're making.
Service businesses
Make sure the scope, hours, and price on the invoice matches exactly what was agreed by email.
Businesses with disputes
Customers pushing back on invoices? Get an automatic audit trail showing exactly what was ordered vs. what was billed.
Fully automated

Connect once.
Never check manually again.

Invoice Auditor runs automatically in the background, 24/7. The moment an invoice is created or updated in QuickBooks it's checked automatically. New sales leads are discovered the same way. You only see something when there's a problem — or an opportunity.
