Simple mode

Build pricing rules in plain English

For straightforward pricing, simple mode lets you add term rows: a field, a multiplier, and an operator. No syntax to learn. Stack multiple terms to build up a complete price.

  • Add terms with dropdowns, no typing required
  • Multiply field values by fixed rates
  • Add flat fees, minimums, and maximums
  • Preview the result in real time as you build
/* Removal quote */
base  = bedrooms * £250
extra = access_fee IF floor > 2
miles = distance * £1.20

/* Apply minimum charge */
total = MAX(base + extra + miles, £150)

= £620.00

Three term rows in simple mode — no code written. The formula builder generates this automatically as you configure each row.

Advanced mode

Full expression power for complex pricing

For trade businesses with multi-variable pricing, advanced mode gives you a full expression editor with access to all 40+ built-in functions. Conditional pricing, banded rates, percentage uplifts — all in one place.

  • Full expression syntax with variables, operators, and functions
  • IF / ELSE conditional pricing branches
  • ROUND, MIN, MAX, CLAMP and other utility functions
  • Date functions: AGE(), DAYS_UNTIL(), WEEKDAYS()
  • Named variables for readable, maintainable formulas
/* Roofing quote — advanced mode */
area   = width * length
rate   = IF(material == "slate", £85, £55)
base   = ROUND(area * rate, 2)

/* Pitch surcharge over 35 degrees */
uplift = IF(pitch > 35, base * 0.15, 0)
labour = MAX(workers * day_rate, £850)

total  = ROUND(base + uplift + labour, 2)

= £2,340.00

Named variables, conditional branches, and utility functions — all readable at a glance. No external scripting needed.
