Every rule here either turns customers away or lets through orders you can't fill. Getting the numbers right is the job.
Daily caps that match real output. Caps can sit on a product, a collection or a customer, and they reset at midnight in the store timezone. Set that timezone in the Schedule section before anything else.
Per-customer limits for drops. On the Pro plan, logged-in buyers are tracked by customer ID and guests by a hashed email. Strict login closes the guest loophole but also blocks guest checkout. That is a business call, not a setting.
Delivery dates and time slots. The Advanced plan adds a picker on product and cart pages, time slots with their own capacity caps, and blackout dates. An expert sizes each slot to what your drivers or kitchen can handle.
Pickup at several locations. Scheduled in-store pickup works across multiple locations. Someone has to decide which slots each location offers and test the flow at each one.
Counter and web on one count. POS and online orders draw down the same limits in real time. Staff need to know what a sold-out slot looks like before a customer asks. POS setup specialists cover that side.
Shipping inside Japan. OrderRules exports orders in Yamato, Sagawa and Japan Post layouts and can import tracking to create fulfillments. Worth an expert if your team ships domestically there.
Too small to outsource. Store hours, a holiday calendar and one daily cap on the free plan take minutes. Set them yourself.
