From the founder

I built Invoice Guard HQ after watching small businesses lose money to billing errors nobody caught. It started as a personal tool. Now it quietly protects other people's bottom lines too.

Trust before connection

Start with a local CSV scan before connecting anything.

The fastest path is the browser-only pre-scan. Your CSV rows stay in the browser tab, and you can review duplicate risk, billing anomalies, and currency conversion anomalies before deciding whether provider import is worth it.

Why This Happens Even to Smart Teams

You're not careless. Your systems simply aren't built to catch these hidden overlaps.

Multiple systems

Invoices move through Stripe, PayPal, and manual spreadsheets that rarely share a single review trail.

Slight variations

Small differences in invoice numbers, amounts, or vendor names slip through under normal review pressure.

Timing and entry errors

Double click errors, failed then retried payments, and corrected invoices create hard to spot duplicates that look fine on the surface.

Multi-currency billing

The same charge can carry an origin amount and a converted amount, or appear in two currencies across exports. Conversion anomaly checks compare those amounts at current exchange rates and flag mismatches that point to rate errors, wrong-currency entries, or overcharges.
