Creating pricing rules in X-1FBO gives you powerful control over how charges are applied — from basic fee overrides to dynamic fuel pricing. This guide walks you through how to build safe, effective pricing rules step by step.
Get Started - Choose the Rule Category
Before setting up a rule, choose where the rule should live. The category determines what type of pricing logic you’re applying.
Available Rule Categories:
Category | Used For |
Fees | Charges for services like lavatory, GPU, facility fees, parking, etc. |
Exceptions | Overrides retail pricing, typically for fuel or services. |
Customers | Pricing tied to specific customers or accounts. |
Payment Methods | Adjustments based on how the payment is made. |
Aircraft | Pricing based on aircraft type, weight class, or model. |
💡 Choose the category first, then build your logic inside that framework.
Define What the Rule Applies To
Next, choose what this rule targets:
Options:
Product/Service – A single item (e.g., Jet-A or Lav Service)
Category – A group of related products or services
All – Everything under the selected category
⚠️ Note: Rules applied to "All" affect every transaction in that category — use carefully.
Name the Rule and Set Priority
Rule Description (Name)
Give the rule a clear, descriptive name that reflects its purpose.
✅ Examples: “Jet-A Discount – AKI Jets – 100+ gal” or “Facility Fee Waived – Based Aircraft”
🚫 Avoid: “Test Rule”, “Customer X”, “Something Fuel”
Rule Priority
Set a priority to determine which rule wins when multiple match:
Lowest
Low
Medium (default)
High
Highest
Critical
🧠 Tip:
Use Critical for override-level rules (e.g., contractual pricing), and Lowest for broad, default pricing.
Set Rule Timing (Optional)
Control when the rule goes into effect:
From Date & Time – When the rule becomes active
To Date & Time – When it expires
✅ You can set rules in the past — helpful for backdated invoices.
🧠 Best Practice: When updating a price, don’t overwrite the old rule. Expire the old one and create a new one. This maintains pricing history and ensures accuracy on older invoices.
Define the Rule Conditions
Conditions are the filters that tell X-1FBO when this rule should apply. You can define one or more conditions, and the rule will only trigger when all selected conditions are met.
Available Conditions:
Customer – Specific account or operator
Aircraft Tail Number – One or more tail numbers
Aircraft Model – Specific aircraft (e.g., Gulfstream G550)
Aircraft Model Category – Groupings like Light Jet, Turboprop, etc.
Tenancy Type – Based or Transient
Flight Type – Arrival, Departure, or Turn
Fuel Minimum Quantity – Trigger only if uplift meets/exceeds this amount
Payment Method – Card, cash, contract, etc.
Contract Fuel – Yes/No
Promo Code – Applied during request
Customer Description – Freeform customer label/category
Set Up the Price (Price Computation)
Now it’s time to tell the system how to calculate the price. This is the core of the rule: it defines the math that gets applied when all your conditions are met.
You can choose one of the following pricing methods:
Methods:
Method | Description |
Fixed | Set a specific amount (e.g., $100 or $0 to waive fee) |
Previous List | This helps you create a rule that applies to another rule |
Retail | This sets your regular retail pricing for an item |
Week Cost | This is used to set the price based on your weekly (daily, monthly or otherwise) fuel price. |
Highest Lot Cost | Use highest available cost from available inventory |
True Cost | Use actual cost from the lot used for fueling. |
Formula | Use variables for custom math: |
Formula Variables:
Q= Quantity upliftedW= Aircraft Empty Weight (lbs)C= Fuel Capacity (gal)S= Aircraft SqFtT= Max Takeoff Weight (lbs)L= Length (ft)MLW= Max Landing Weight (lbs)
✅ Example: Create a ramp fee formula that scales by aircraft size or fuel capacity.
🧠 Pro Tip: Formula pricing gives you ultimate flexibility — but test carefully. Even small errors in logic can result in unintended charges.
Add an Additional Product (Optional)
Want a second product or service added automatically when this rule applies?
Use the Add Product option to insert another line item on the invoice.
✅ Example: If AKI Jets buys Jet A, and you want to also charge a Credit Card Fee, add it here. Both will be invoiced together when the rule fires.
Final Step: Save the Rule
After reviewing all inputs, click Save to activate the rule.
🧠 Best Practice: Test your new rule using a mock invoice or internal request to confirm it behaves as expected — especially if you're stacking logic or using formulas.
