Inventory and unit counts

Miko Product Rentals manages availability based on your unit count: the number of physical units you own of each rentable item. This is separate from Shopify's own inventory quantity and is managed entirely within Miko.

Where to find it

Open Apps → Miko Product Rentals → Rental Products, click the product, and look under Inventory and duration for Units available. Products with variants also have a Variants section, with units for each variant.

How to set it up

1. Open the product

   In Rental Products, click the product you rent out.

2. Set the unit count

   Under Inventory and duration, set Units available to how many can be out at the same time.

3. Set units per variant

   If the product has variants, click Sync variants, then set the units for each variant and click Save variant.

4. Save

   Click Save settings.

Per-variant inventory

If your product has variants (for example, Small Kayak and Large Kayak), each variant has its own unit count and its own availability pool. A booking for the Small Kayak variant does not affect the availability of the Large Kayak variant. You can set a different unit count for each variant from the product rental settings page.

Example

How unit counts work

If you own 3 kayaks, set the unit count to 3. When a customer books a kayak for a given date range, one unit is reserved for those dates. A second customer booking the same item for an overlapping date range reserves another unit. Once all 3 units are booked for a date range, those dates show as unavailable to any further customers browsing the date picker. A unit is held from the moment the order is placed, and capacity is checked again when payment is captured. If two orders still clash, the later one is flagged Needs review on the Bookings page rather than being refused, so you can contact the customer.

Leaving buffer time

Consider setting your unit count conservatively if you need time between rentals for cleaning, maintenance, or transit. For example, if you own 3 units but realistically can only turn around 2 rentals at a time, set the unit count to 2. Blocked dates can close off specific days, but they cannot yet be added from inside the app.
