Why it matters

Every month, money slips through the cracks.

You bill your customers for shipping in PostalMate. Your carriers bill you separately — bundled onto a credit-card statement that lands weeks later.

When a carrier quietly charges more than you collected — an address correction, a dimensional-weight bump, a fuel or residential surcharge — that gap comes straight out of your margin. Across hundreds of packages, it adds up fast.

Drop & Cross lines the two up, package by package, so nothing slips by unnoticed.

Surcharges you never billed for

Catch corrections and weight adjustments the carrier added after the sale.

Mismatches, found instantly

Matched by tracking number across thousands of rows in a moment.

A clean record to act on

One tidy spreadsheet you can file, share, or use to chase a refund.

How it works

Three steps. About a minute.

No installs, no accounts. Just drop in two files and cross-check them.

Private by design

Your numbers never leave your browser.

Drop & Cross runs entirely on your own computer. There's no upload, no server, and no account — your billing files are read and matched locally, and the moment you close the tab, they're gone. That's exactly why we can offer it free.

What you get

One spreadsheet that tells you everything.

Every package from your PostalMate report, lined up against the carrier's charge and the difference between them.

Red — the carrier charged more than you collected. Money to chase.
Blue — you charged more than the carrier billed. You're ahead.
Black — an exact match. Nothing to do.

Good to know

Questions, answered.

Is it really free?
Yes — completely. No account, no limits, no card required. The tool runs on your own machine, so there's nothing for us to charge for.
Is my billing data safe?
It never leaves your browser. Your files are read and matched locally on your computer — nothing is uploaded to a server, and nothing is stored. Close the tab and it's gone.
What files do I need?
Two: your PostalMate Reconcile Carrier Billing report (CSV), and a carrier invoice or card statement — a UPS or FedEx invoice, or an American Express statement, in CSV, Excel or PDF.
Which carriers are supported?
UPS and FedEx invoices, plus American Express statements. The tool matches every shipment by its tracking number, so as long as the tracking numbers line up between the two files, it'll find the pairs.
Does it work offline?
Yes. Once the page has loaded, you can disconnect from the internet and it'll still run — everything happens in your browser.
Do I need to install anything?
No. It runs in any modern web browser — Chrome, Edge, Safari or Firefox. There's nothing to download or set up.
What is PostalMate?
It's the point-of-sale and shipping software that many independent mailbox and pack-&-ship stores run on. If you bill customers for shipping through PostalMate, this tool is built for you.
