Invoice Rules / Bundled Sales

Navigate to: Invoice Extra > Invoice Rules

 

Invoice rules (also called bundled sales) let you automatically add related items, apply discounts, or enforce package deals when a main “trigger” item or combination of items is sold. This works across:

 

Invoices

Quotations

Job Cards

Sales Orders

 

How It Works:

When the main/trigger item (or stock group) is added to a document:

The system automatically adds the bundled item(s).

Predefined discounts, quantities, or descriptions apply instantly.

 

Benefits:

Speeds up sales and invoicing – no manual addition of common extras.

Ensures customers get complete packages (e.g., tyre + valve, service kit).

Reduces errors and missed upsell/cross-sell opportunities.

Supports trade-ins, mandatory accessories, and promotional bundles.

 

Real-World Examples

Car Battery Trade-In

When selling a new car battery, a customer may receive a discount for trading in their old battery.

The used battery must be loaded as a trade-in item.

When the new battery is sold, Smart-IT automatically adds the trade-in item to the invoice.

 

Tyre and Valve

When selling a tyre, a valve is also required.

When the tyre is added, Smart-IT automatically adds the valve to the invoice.

 

Service Packages — Selling a “2000 km Service” item auto-adds oil, filter, labour, etc., with bundled pricing.

 

Monetary Value Above Minimum Amount (Threshold Discount)

You can give the customer an automatic discount if their invoice subtotal exceeds a certain amount — no specific trigger item required.

How to set it up:

Set Minimum Total Inclusive to your threshold (e.g., R5,000).

Skip the Requirements section (leave it empty — no stock group or item needed).

Go to the Action Tab:

Add an Is Discount item (create one in Stock Main if needed; mark it as “Is Discount” in Additional Info tab).

In the Line Total Inc = Total Discount % column, enter the discount percentage you want to give (e.g., 5% or 10%).

The system applies this discount automatically when the invoice total (inclusive) reaches or exceeds your minimum threshold.

This is perfect for volume-based promotions like “Spend R5,000 or more → get 7% off your entire order.”

How to Set Up an Invoice Rule – Step-by-Step

 

1. Go to: Invoice Extra > Invoice Rules

2. Click Add Rule (or edit an existing one)

3. Enter a clear Rule Name (e.g., “Tyre + Valve Bundle”, “Battery Trade-In”, “2000km Service Package”).

4. Filters & Checks (controls when the rule triggers)

Match Only Once — Enable if the match must take place only once, for example, You sell a tyre and client gets a valve.  Sell 2 tyres, client still gets only 1 valve.

Minimum Total Inclusive —  The rule will not apply if the document total is below the specified amount.

              Example:

              If the minimum is R3,000 and the tyre value is R2,000, the rule will not trigger.

Type — Limit to Cash clients, On Account, or Any.

Web Orders — Include or exclude rules from applying to online/web orders.

Requirement Filter (AND / OR)

        Determines how multiple requirement rows are evaluated.

        Example (Dunlop and Pirelli rows):

AND – Both Dunlop and Pirelli must be sold to trigger the rule.

OR – Selling either item will trigger the rule.

Branch — Select a specific branch or leave blank for all branches.

 

5. Requirement

specify the triggers/requirements for the rule. The requirement filter setting at top specifies if all items are required (AND) of any of the requirement items (OR).

Stock Group / Stock Item

Choose whether the rule applies to:

A Stock Group (e.g. Tyres – any tyre triggers the rule), or

A Specific Stock Item (e.g. a particular tyre).

 

Quantity

Specify the quantity to add.

 

Action Tab

Invoice_Rules_Action

 

 

6. Action Tab

Add Item — Choose the item(s) to auto-add (e.g., valve, trade-in battery, oil filter).

Line Description — Custom text for the added line. (Blank for default)

Line Discount % —  Apply a discount percentage to the added item.

Line Total Inc = Total Discount % — Discount % on the document total inclusive. Use only with “Is Discount” items (Stock Main > Additional Info tab).

Line Qty (for added item):

Set to 1 → Quantity matches the trigger item exactly (e.g., 4 tyres → 4 valves) and cannot be changed manually.

Set to 0 → Allows manual adjustment of the added item’s quantity.

 

Once saved, test the rule by adding the trigger item to a new invoice/quote/job card — the bundle should appear instantly.

This feature turns complex sales into one-click simplicity, improves consistency, and boosts average order value through smart automation.
