Warehouse JSON
3PL packing slip API
Multi-brand packing slips from the JSON you already have. Accent and logo per client. Not a WMS.
Third-party logistics teams need a document that matches the carton, not a marketing page. Slipmill prints from the JSON you already store for the wave or the order. Each client can send its own brand.name, brand.accent, and logo_url.
You keep the WMS, rates, and carriers. We are not a warehouse system. We print the slip. Tracking is an optional field if you have it at render time.
Scale is the plan when volume is the job: 15,000 included renders and metered overage.
