Meet Packit: Catching Compliance Errors Before the Carton Ships

Introducing Packit by Crstl: B2B Routing Guides Compliance

The hidden tax of B2B compliance

Any brand that ships to B2B trading partners, such as retailers, distributors, wholesalers, and grocery and warehouse networks, knows the quiet tax of doing business with them: chargebacks. A mislabeled carton, a late or inaccurate ASN, a barcode an inch out of place. Every trading partner has its own rulebook, and each deviation is a fine waiting to happen. The frustrating part is that by the time a chargeback lands, the shipment is long gone and the error is unfixable.

Packit by Crstl exists to close that gap. It's a warehouse-floor app that turns any partner's packing and shipping requirements into a guided, verifiable workflow, so errors get caught at pack time, while the carton is still open and a worker can still fix it.

How it works

Packit walks warehouse and 3PL workers through a compliance checklist for each shipment, built from the trading partner's actual requirements. Instead of relying on tribal knowledge, or the one veteran who remembers how a given partner wants its labels, the rules live inside the checklist itself. That makes onboarding faster and correctness system-enforced rather than supervisor-dependent.

The standout piece is AI-powered photo verification. As workers pack, they photograph key compliance steps, such as a GS1-128 label on the front face of a carton. Each photo is automatically checked against that partner's specific criteria (correct placement, scannable barcode, unobscured, within the right margins). Within seconds, the worker sees one of four results inline: pass, fail, "not confident," or a processing error. A confirmed failure on a critical step blocks submission until it's fixed or a supervisor overrides it, while ambiguity or a technical glitch never punishes the worker the same way a real mistake does.

The result: a worker who labels a carton wrong gets immediate feedback to correct it before the carton is sealed, rather than discovering the problem weeks later in a chargeback notice.

Built to connect

Packit isn't an island. It includes a source-agnostic ingest layer, meaning any external system, whether an ERP, a WMS, an EDI platform (Crstl or any other EDI provider), can push purchase orders, labels, and ASN data straight into Packit through authenticated API calls. Admins create and manage their own API keys and permissions directly in the Packit UI, no engineering tickets required.

That eliminates one of the oldest sources of warehouse error: manual data re-entry. When PO data flows in automatically, workers see accurate, current order information the moment it lands in the source system, not hours later after someone re-keys it by hand (and introduces the very transcription errors that cause chargebacks).

The bigger picture

Packit completes the compliance loop end to end: an order arrives, a packing session begins, the shipment is verified and packed correctly, and the ASN is confirmed, with no human stuck in the data-entry path and no compliance step left to memory. For any business shipping to demanding B2B partners, it turns partner compliance from a recurring penalty into a solved, repeatable process.

In short: Packit is where trading partner requirements become a workflow workers can actually follow, and where AI quietly checks their work before it's too late to fix.
