Proposal pricing psychology: what optional items do to a yes

A proposal priced as one number asks the client a yes or no question. A proposal priced as a base scope plus one or two optional extras asks a different question: which version do you want? That shift is the core of proposal pricing psychology, and it is why almost every well built quote carries at least one optional line.

The 18 proposal and quote templates counted for this article all follow that pattern. Every one has at least one optional item; eight have two; none has more than two. The table above lists them. It is a small sample, but it shows a deliberate restraint: enough choice to make the client an active participant, not so much that choosing becomes work.

One number invites a no

When a client sees a single total, the only lever they have is the price itself. They can accept it, reject it or ask for a discount. When they see a base with extras, they have other levers. They can drop the extras to fit a budget without asking you for anything, or add one because it solves a problem they had not raised.

This changes the conversation after the proposal too. A follow up about a single total is “have you had a chance to look at it”. A follow up about extras is “did you want the irrigation left in”. The second is easier to answer, and it assumes the job is going ahead.

The base and the extras

The base must stand on its own. If the core scope only works with an extra added, the extra is not optional; it is a hidden part of the price, and the client will feel misled when they find out.

Good optional items share three traits:

• They are useful but separable. Drone footage on a shoot, a care plan on a website, a beverage package on catering. The job is complete without them.
• They are priced clearly. A fixed amount, or a unit price with a quantity. “Price on request” is not an option.
• They make sense to add now. An extra shoot day costs less when it is booked with the first; a safety switch is cheaper to install while the electrician is on site.

How to set each price, from cost plus to value based, is in how to price a proposal and value based pricing vs hourly.

How many options

The best known study on this is Iyengar and Lepper’s work on choice overload. Shoppers offered a display of 24 jams stopped more often than those offered 6, but far fewer of them bought anything. Nielsen Norman Group draws the same lesson for interfaces: each extra choice adds effort, and too many make people abandon the decision.

For a small business proposal, one or two extras is the practical limit. The templates never go past two. If you find yourself listing five add-ons, group them into one package or move them into a later conversation.

Order and anchoring

Psychologists describe anchoring as the tendency for an earlier number to influence how later numbers are judged. In proposals, this is often turned into the advice to show a premium option first so the standard one looks cheaper. Use it carefully. A client can spot a decoy package that nobody is meant to buy, and it costs you trust.

A more honest use of order is to list items in the sequence the work happens, core scope first and extras after, with each extra’s price beside it. The client sees the base total first and then decides what to add. That is anchoring on the price you actually want them to accept.

Ticked or unticked

An optional item can arrive ticked, so the client removes it, or unticked, so they add it. Pre ticking raises the first total the client sees, which can make the whole proposal feel expensive. It also risks the client feeling something was slipped in.

Pre tick only what nearly everyone takes and would expect, such as travel for an out of town booking. Leave genuine upgrades unticked. In OneCraft each optional item has a selected by default setting, so the choice is per item. See optional line items for how the mechanics usually work in quoting tools.

Quantity the client controls

Some choices are not yes or no but how many: shoot days, session packs, square metres of turf, downlights in a kitchen. Letting the client adjust a quantity within limits you set is another form of option. It keeps the scope in their hands without opening it up entirely.

OneCraft items can be marked quantity editable with a minimum and maximum. The client’s view shows a quantity control, the totals update as they change it, and the accepted quantity flows to the invoice. A floor protects your minimum job size; a ceiling stops a client booking more than you can deliver.

The total the client sees

Whatever the client selects, the summary should show the money honestly: subtotal, any discount, the tax line, the total, and any deposit due now with the balance. If your prices include GST, the ATO allows the invoice to say the total includes GST when GST is exactly one eleventh. The point is that the client should never discover a number after accepting.

A worked example

Stillwater Films quotes a festival video. Pre-production $1,500, two shoot days at $2,200 each with the quantity editable from two to four, editing $2,800, and drone footage as an unticked extra at $750. The base subtotal is $8,700, GST $870, total $9,570. The client adds a third shoot day and the drone: subtotal $11,650, GST $1,165, total $12,815. They chose a bigger job than the one they were quoted, and nobody had to ask.

The quote with optional extras page shows how to build this, the quotation example shows a complete quote, and pricing in a slide deck rather than a document is covered in how to present pricing in slides.
