Select one of the three options below based on your configuration. | **Note:** The options in this step may vary depending on your [time and duration settings](https://helpdesk.resmarksystems.com/en-us/article/how-can-i-set-up-the-date-and-time-of-my-inventory-in-resmark-17ysuwj/). This step is disabled if you selected [Variable Dates](https://helpdesk.resmarksystems.com/en-us/article/how-can-i-set-up-the-date-and-time-of-my-inventory-in-resmark-17ysuwj/). If so, skip to the [next step](https://helpdesk.resmarksystems.com/en-us/article/how-do-i-set-up-my-product-inventory-general-settings-f7lgwh/). ### Options 1. [Time = Repeat several times per day](#3-option-1-repeat-several-times-per-day) 2. [Time = Do not repeat several times per day > Duration = Start and end the same day](#3-option-2-do-not-repeat-several-times-per-day-gt-start-and-end-the-same-day) 3. [Time = Do not repeat several times per day > Duration = Span multiple days](#3-option-3-do-not-repeat-several-times-per-day-gt-span-multiple-days) --- ### Option 1: Repeat Several Times Per Day If your time settings look like this, you are in the right place: ![Time settings showing Repeat several times per day](https://storage.crisp.chat/users/helpdesk/website/51cecd630a16380/file-orqdrp0zvl_1mvufr3.png) In this step, you will define the start and end time for your inventory and how often it repeats per day. For example, if your initial appointment **start time** is 9:00 AM and your product **repeats** every 120 minutes, Resmark will generate inventory at 9:00, 11:00, 1:00, and so on until the **end time**. No start times will be created beyond your defined end time, but appointment durations can exceed it. To begin, define your product duration and how often inventory repeats (as shown in the screenshot below). This setting is flexible and allows for overlapping inventory or gaps between appointments. ![Duration and repeat interval settings](https://storage.crisp.chat/users/helpdesk/website/51cecd630a16380/file-z7i6qds1nh_1ibpehq.png) Here are additional examples of how this feature could be used: **Duration** = 2 Hours, **Repeat** = 60 Minutes Your product starts every hour after the initial start time. Since the product lasts 2 hours, there will be an overlap between each appointment. **Duration** = 1 Hour, **Repeat** = 120 Minutes Your product starts every two hours after the initial start time. Since the product only lasts 1 hour, there will be a 1-hour gap between each start time. Next, set your start and end times. The default is 9:00 AM to 5:00 PM. **Start Time:** The start time for your first appointment of the day. **End Time:** The cutoff start time for your final appointment of the day. Appointment durations can exceed the end time, but new appointments cannot begin after it. You can customize hours by day or apply the same hours to all days. Uncheck the box above a day if you are closed on that day. In the example below: **Duration** = 1 Hour 30 Minutes **Repeat Every** = 120 Minutes (2 hours) **On The Following Days** = 9:00 AM to 6:00 PM (Sunday through Saturday) ![Configuring start and end times by day of the week](https://storage.crisp.chat/users/helpdesk/website/97d8bc2a71839800/05d1137f-09ff-45da-ae3d-48bc02_f677mf.gif) With this configuration, the following timeslots are created (Sunday through Saturday): 9:00 AM to 10:30 AM 11:00 AM to 12:30 PM 1:00 PM to 2:30 PM 3:00 PM to 4:30 PM 5:00 PM to 6:30 PM | **Note:** In the previous example, 5:00 PM is the latest timeslot available due to the **Repeat Every** and **End Time** restrictions. If the end time were changed to 7:00 PM, it would meet the 120-minute repeat requirement and add an additional 7:00 PM to 8:30 PM appointment. After completing this step, continue to [General Settings](https://helpdesk.resmarksystems.com/en-us/article/how-do-i-set-up-my-product-inventory-general-settings-f7lgwh/) to define a few more options before generating your inventory. If there are unique days with special hours (such as holidays or promotional dates), you can adjust those after your inventory is generated. --- ### Option 2: Do Not Repeat Several Times Per Day > Start and End the Same Day If your duration settings look like this, you are in the right place. If not, try [Option 3](#3-option-3-do-not-repeat-several-times-per-day-gt-span-multiple-days). ![Duration settings showing Start and end the same day](https://storage.crisp.chat/users/helpdesk/website/51cecd630a16380/file-jxmibqe3vs_18v2k1c.png) On this step you can: * Set your product start time * Set your product end time * Add additional time slots * Disable days that you are closed ![Configuring time slots and disabling closed days](https://storage.crisp.chat/users/helpdesk/website/2a486d1a5b5c8c00/815a7762-1c7d-4eb6-881a-f42526_1o0ot0k.gif) From the example above, the settings are: **Sunday:** 9:00 AM to 11:00 AM **Monday:** 9:00 AM to 11:00 AM **Tuesday:** Closed **Wednesday:** Closed **Thursday:** 9:00 AM to 11:00 AM **Friday:** 9:00 AM to 11:00 AM **Saturday:** 8:00 AM to 10:00 AM; 12:00 PM to 2:00 PM; 4:00 PM to 6:00 PM After completing this step, continue to [General Settings](https://helpdesk.resmarksystems.com/en-us/article/how-do-i-set-up-my-product-inventory-general-settings-f7lgwh/) to define a few more options before generating your inventory. If there are unique days with special hours (such as holidays or promotional dates), you can adjust those after your inventory is generated. --- ### Option 3: Do Not Repeat Several Times Per Day > Span Multiple Days If your duration settings look like this, you are in the right place. If not, try [Option 2](#3-option-2-do-not-repeat-several-times-per-day-gt-start-and-end-the-same-day). ![Duration settings showing Span multiple days](https://storage.crisp.chat/users/helpdesk/website/119c452634331800/51d36ff2-df8d-4af6-af62-c063c5_19f68ht.png) If your products span multiple days, the first thing you need to do is define the duration of your inventory. Set the default number of days your product lasts. You can also customize the duration for certain start days (see example below). ![Setting multi-day duration with per-day customization](https://storage.crisp.chat/users/helpdesk/website/f04e670108aa3800/3dbecd4b-d5df-44d0-a09b-196bce_15m7zrb.gif) Next, define the **start time** and **end time**. You can customize start times for each individual day or apply the same time to all days.
