How pricing logic works in a Quotify form

· 4 min

The price your customer sees at the end of a Quotify form isn’t magic. It’s a sum of the choices they made along the way. This article explains how those choices roll up into a number, so you can plan your form’s pricing rules before you build it.

The building blocks

Almost every Quotify form is built out of just four kinds of pricing rules:

1. Fixed prices per option

The simplest case. Each option (a checkbox, a radio choice, a dropdown item) has a price attached. Pick the option, the price goes into the total.

Example: “What kind of clean do you need?”

  • Regular clean: £80
  • Deep clean: £140
  • End-of-tenancy: £220

Selecting “Deep clean” adds £140 to the total. Selecting nothing adds £0. Done.

2. Per-unit multipliers

Used when a number directly drives the price, usually a quantity, an area, or a duration. The customer enters or selects a number, and you multiply it by a per-unit rate.

Example: “How many bedrooms?”

  • £40 per bedroom

A four-bedroom property adds £160 to the total.

This is where most service quotes get their muscle: per-room, per-hour, per-square-metre, per-guest, per-window.

3. Conditional add-ons

Optional extras the customer can layer on top — usually rendered as a multi-select list. Each add-on has its own price.

Example: “Any add-ons?”

  • ☐ Inside oven (+£25)
  • ☐ Inside fridge (+£20)
  • ☐ Ironing service (+£35)

The customer ticks what they want, the total grows accordingly.

4. Percentage surcharges (and discounts)

Some prices aren’t a flat figure, they’re a percentage of everything else: a weekend rate, a rush fee, a premium-finish uplift, or a bulk discount. Set any option’s price to a percentage instead of a pound amount and Quotify works it out from the rest of the quote.

Example: “When do you need it?”

  • Standard: +0%
  • This weekend: +15%

On a £300 job, the weekend option adds £45. Multiple percentages stack additively (10% + 20% is +30% of the base, not compounding). There’s a full walkthrough in charge a percentage, not just a flat fee.

How they combine

Most real-world forms use several of these together. A house-cleaning quote might look like:

  1. Clean type (fixed price) picks the base
  2. Bedrooms × per-room rate (per-unit) scales it
  3. Add-ons (conditional) layer extras on top
  4. A weekend rate (percentage) lifts the lot when it applies

Total = base + (bedrooms × rate) + add-ons + any percentage surcharges

That’s it. A handful of rules, infinite combinations.

Designing your pricing: the order that matters

When you’re sketching out a form, work in this order:

  1. What’s the base of the price? A category, a service tier, a “type of job”. This is usually your first question.
  2. What scales it up or down? Quantities, sizes, frequencies, anything that multiplies. These are usually questions 2-4.
  3. What’s an optional extra? Add-ons go near the end so they feel like genuine choices, not required steps.

This order also matches how customers think about pricing (“what kind of thing, how much of it, plus what extras”) so the form feels intuitive while it’s quietly doing the maths.

Showing your working

By default, Quotify shows the customer a live total as they answer. If your pricing has multiple components, you can also show a detailed breakdown, useful for higher-ticket services where the customer wants to see why it costs what it costs.

For pricing that genuinely depends on something you can’t capture in a form (site condition, access, supplier costs that change), use an estimate range instead of a single number. It sets expectations honestly and protects your margin.

Common pitfalls

Over-engineering the rules. It’s tempting to add multipliers for every possible variable, but every extra rule adds friction for the customer. If a factor adds less than 10% to the price, consider rolling it into the base rather than asking about it.

Underpricing the base. Quotify’s pricing logic is only as good as the numbers you put in. If your base rate doesn’t cover your actual costs, multipliers won’t save you. They’ll just make the underpricing scale. Sense-check the output against your real jobs before going live.

Hidden surcharges. If your real-world quote always ends up higher than the form’s number (travel, parking, weekend rates), bake those into the form too. Customers expect the form’s number to be close to the final invoice; anything more than a 10-15% gap erodes trust.
