Custom prices are per-customer overrides that sit on top of your pricing tiers — one-off deals for a specific customer (or customer tag) on a specific product (or slice of the catalog). Nebo's Painting Service gets a special price on REGAL SELECT MATTE -BASE 2, regardless of their Painter tier.
In the POS mode, open Products in the left sidebar — Custom prices is the second top tab across.

When a customer is attached to a sale, Rundoo rings each line like this:
A custom price isn't just one row for one product at one price — it's a small rule with four parts.
| Part | Choices | What it means |
|---|---|---|
| Assign to | Customer · Customer tag |
Who this price applies to. Customer targets one customer (optionally narrowed to a specific Job). Customer tag targets every customer carrying that tag — handy for broad cohorts like VIP or Employee. |
| Products | By rules · By product · All products |
What this price applies to. By product picks items one at a time. By rules scopes by Vendor, Department, Class, Fineline, or Product tag — so you can say "all Benjamin Moore, all paint sundries, this whole fineline." All products is the blanket option. |
| Pricing strategy | Discount · Margin · Dollar |
How the price is computed. Discount is a percentage off a reference tier (15% off Tier 1 Msrp). Margin targets a gross margin percentage off cost (30% margin). Dollar is a fixed price ($42.99). |
| Schedule and location | Start date, expiration date, one or more locations | When and where the price is live. A price that started yesterday with no expiration applies indefinitely at every location you picked. Set an expiration to auto-retire it — useful for short-term deals you don't want to remember to turn off. |
<aside> 💡
Custom prices stack on top of tiers — they don't replace the tier assignment. If a customer has 3 custom prices for specific SKUs, those 3 items ring at the custom price and every other item rings at their tier price. You don't have to duplicate the whole tier.

Use By rules for catalog slices (vendor, department, class, fineline, or product tag) and All products for blanket overrides.Discount, Margin, or Dollar, then fill in the corresponding input. Discount and Margin require a Reference tier (so the system knows what to discount from); Dollar doesn't.
