Weight Presets

Admin

Weight presets define the standard weight options available for cannabis products sold by weight. Instead of manually entering a price for every product-weight combination, you configure preset weights once and pair them with Quality Tiers to generate a full pricing matrix.

You can modify these defaults, add additional presets, or remove ones you do not use.

Accessing Weight Presets​

  1. Log in to the Admin Panel.
  2. Navigate to Weight Presets (accessible from the admin menu when cannabis features are enabled).
  3. The weight preset list loads, showing all configured presets.

Understanding the Weight Presets Table​

The index page displays a table with the following columns:

ColumnDescription
CheckboxSelect presets for bulk actions.
NameThe display label for the weight (e.g., "3.5g").
Weight (g)The weight value in grams.
Sort OrderThe display order of the preset on the POS and in lists.
ActiveWhether the preset is currently active.
POS VisibleWhether this weight appears on the POS register.
ActionsEdit and Delete buttons.

A Select All checkbox at the top selects all presets. Selected presets can be removed using the Delete Selected button for bulk deletion.

Adding a New Weight Preset​

  1. Click the New Weight Preset button.
  2. Fill in the fields:

Name​

The display name shown on the POS register and in reports.

  • Required: Yes
  • Example: "3.5g", "Half Oz", "2g"

Weight Value (grams)​

The weight value in grams. This is used for compliance calculations (equivalent gram tracking) and inventory management.

  • Required: Yes
  • Format: Decimal (e.g., 3.5)
  • Must be greater than zero.

Active​

Checkbox to set whether the preset is active. Inactive presets are not available for use.

POS Visible​

Checkbox to control whether this weight appears as an option on the POS register.

  1. Click Save Weight Preset.
Common additions

Some stores add a 0.5g preset for pre-rolls or a 2g preset for budget options. Add whatever weights make sense for your product catalog.

Editing a Weight Preset​

  1. Click the Edit button on the preset row.
  2. Modify the name, weight value, active status, or POS visibility.
  3. Click Save Weight Preset.
Editing weight values

Changing the weight value on an existing preset affects compliance calculations going forward. Historical sales retain their original weight values. If you need to track a different weight, consider creating a new preset instead.

Removing a Weight Preset​

  1. Click the Delete button on the preset row.
  2. Confirm the deletion.

You can also delete multiple presets at once:

  1. Select presets using the checkboxes.
  2. Click Delete Selected.
  3. Confirm the deletion.
Impact on pricing matrix

Deleting a weight preset removes the corresponding weight from all Quality Tier pricing matrices. All prices for that weight across all tiers will be lost. This action cannot be undone.

Weight Presets and the Pricing Matrix​

Weight presets form the rows of the quality tier pricing matrix. Each preset gets a price for each active quality tier:

              AA      AAA     AAAA    AAAA+
  1g        $8.00   $10.00  $12.00  $14.00
  3.5g     $25.00   $32.00  $40.00  $48.00
  7g       $45.00   $58.00  $72.00  $88.00
  14g      $80.00  $105.00 $135.00 $165.00
  28g     $140.00  $190.00 $250.00 $310.00

When you add a new weight preset, a new row appears in the matrix with empty prices. You must navigate to Quality Tiers (at /admin/quality_tier_settings) to fill in the prices for the new weight.

How Weight Presets Work on the POS​

When a budtender selects a product with quality tier pricing:

  1. A weight selector appears showing all active, POS-visible weight presets.
  2. Each option displays the weight label and the calculated price for that product's quality tier.
  3. The budtender taps the desired weight.
  4. The item is added to the cart with the correct weight and price.

Products Without Quality Tiers​

For products that use weight presets but do not have a quality tier (e.g., accessories sold by weight), the product's base price is used regardless of the selected weight. In this case, weight presets serve as a convenience for selecting the correct weight for labeling and compliance, not for price calculation.

Weight Presets and Compliance​

Weight presets feed directly into compliance tracking:

  • Equivalent gram calculations -- Each sale records the weight in grams for daily purchase limit enforcement.
  • SLGA reporting -- Weight data is included in Saskatchewan Liquor and Gaming Authority reports.
  • Daily limits -- The system tracks total grams sold per customer per day. Weight presets ensure accurate gram calculations.
Accurate weights are critical

Incorrect weight values in presets will produce incorrect compliance data. Always verify that the weight value matches the actual product weight. A "3.5g" preset must have a weight value of exactly 3.5.

Scale Integration​

If your store uses a digital scale (enabled via Settings > Edit Settings > Hardware & System tab), budtenders can weigh products directly on the POS:

  1. Place the product on the scale.
  2. The POS reads the weight via Web Serial API.
  3. The system finds the closest matching weight preset.
  4. The budtender confirms or adjusts the selection.

This is useful for products sold as loose flower where the exact weight may vary slightly.

Best Practices​

  • Stick to standard weights -- 1g, 3.5g, 7g, 14g, and 28g cover the vast majority of use cases. Only add custom presets if you have a genuine business need.
  • Sort logically -- Order presets from smallest to largest. This is intuitive for budtenders.
  • Keep labels short -- "3.5g" is better than "3.5 grams (eighth)" on the POS register. Space is limited.
  • Audit quarterly -- Remove presets for weights you no longer sell. Fewer options means faster checkout.
  • Test on the POS -- After making changes, open the POS register and verify that the presets appear correctly.
