Updated February 24, 2026 Step-by-step walkthrough
Step-by-Step Instructions
1. Open the Products Module
- Click the Products tab (box icon) in the left-hand sidebar.
- You will see your Catalog with all active products.
2. Select the Product
- Click the name of the product you want to configure.
- This opens the product’s detailed view.
3. Access Volume Pricing
- In the product detail view, click Volume Price.
- This is where you can create pricing tiers based on supply quantity.
4. Select the Supply Level (Per Eye)
- Choose the appropriate option based on supply:
- 2 Boxes (for One Eye) → typically used for a 6-month supply
- 4 Boxes (for One Eye) → typically used for a 12-month (annual) supply
Otto calculates multi-box pricing per eye, not per patient.
5. Enter the Price
- Enter the total price for the selected number of boxes per eye.
- Repeat this process for any additional supply levels you wish to offer.
6. Add Additional Discounts (Optional)
- You can continue adding pricing tiers for different supply quantities.
- Each tier must be entered individually.
7. Click Save
- Click Save to apply your volume pricing changes.
Understanding Multi-Box Pricing (Per Eye Calculation)
Otto calculates volume pricing per eye, meaning you enter half of the full patient supply and half of the total price.
Example: Daily & Bi-Weekly Lenses
- 3 Months = 1 box per eye
- 6 Months = 2 boxes per eye
- 12 Months = 4 boxes per eye
Example: Monthly Lenses
- 6 Months = 1 box per eye
- 12 Months = 2 boxes per eye
If a patient purchases lenses for both eyes, Otto automatically combines the per-eye pricing to calculate the full order total.
Important Notes
- Volume pricing must be configured individually for each product.
- Pricing tiers apply to both in-clinic quotes and online store purchases.
- Ensure pricing aligns with your rebate programs to maintain accurate annual supply quotes.
- If pricing appears incorrect in a quote, confirm that:
- The correct volume tier is saved.
- The pricing was entered per eye (not full supply).
When to Contact Support
- If volume pricing is not appearing correctly in quotes.
- If supply levels do not match expected rebate logic.
- If pricing appears inconsistent after saving.
