Every box, its renter and its paperwork

The mailbox desk shows each box with its renter, rent, paid-through date and whether its PS Form 1583 is verified, and calls out the boxes waiting on a form and the ones past their paid-through date.

What software can and cannot do for a CMRA

USPS publishes no API or file upload for its CMRA Customer Registration Database, so each PS Form 1583 is entered by the store in the USPS web application. No mailbox software can file it for you, Pack and Kin Studio included. What the roster does is tell you which boxes opened, closed or changed before each quarterly certification. The CMRA compliance guide walks through the rules.

Questions

What store owners ask first

Does it track Form 1583 for each box?
Yes. Each rental shows whether its PS Form 1583 is verified, and the CMRA box-holder report lists every holder for the store’s own records. Entering the forms in the USPS database is still done by the store.
How do I pay for shipping labels?
From a prepaid wallet on your account. Pack and Kin Studio fronts each label at purchase and takes it from that balance, which also means a label cannot be bought against an empty wallet. Funding it is the one setup step between your first sign-in and your first label.
Which carriers can I ship with?
USPS, UPS and FedEx: rating, label purchase, voids, return labels and claims on all three. We would rather name three carriers that work than a longer list that does not.
Is it really free?
The plan is. You pay for the labels you buy, any add-on pack you deliberately switch on, storage beyond the free 1 GB, and a fee when you top up your shipping wallet with a credit card, shown before you confirm it. There is no card to enter to apply, and nothing expires.
How do I get started?
Request an invite. Our team reviews every application, sets your store up with you, and emails your sign-in. Then fund the wallet and ring the first sale.

The rest of the counter

The register, the three carriers, mailboxes and the books share one set of records on the free plan; kiosks are an add-on.
