Tracking

Scans, as they happen

Every label is tracked from the moment it is generated. Check a number any time, or let us tell you when its status changes — each event carries the facility that scanned it, so you can tell a delay from a dead end.

Pricing

Pay per label, by weight

Top up your balance and it draws down as you generate. No subscription, no per-carrier fee, and voided labels are credited back within 24 hours.

How pricing works

per label
Priced by weight bracket
Set per account and per series
Sub-accounts inherit yours unless you set theirs
Voided labels credited back within 24 hours
Rates depend on your volume and the series you ship on, so we quote them per account rather than publishing a single table.

Balance

credits

Top up your balance and it draws down as you generate. No subscription and no per-carrier fee — add credits by card or crypto, and see every charge in your ledger.
