I will develop an online calculator for the cost of a pet portrait on order

I will create an interactive calculator for you that calculates the total cost of a custom pet portrait directly on your website — without having to correspond in direct messages for every number. The client selects the canvas or paper size, execution technique (pencil, watercolor, oil, digital painting), the number of animals in one portrait, execution urgency and the presence of a frame — and immediately sees the price and approximate delivery time. This relieves you of the routine of manual calculations and speeds up the customer's decision-making.

I will adjust the calculation logic to your current pricing system: base rate for size, coefficients for technique and for each additional animal, markup for urgency (for example, +30% for a deadline of less than three days) and frame cost by type and size. All multipliers will be placed in a separate settings file so you can change prices yourself without contacting the developer. I will adapt the calculator for mobile screens, add smooth animation for amount changes and a button to send a request with the ready calculation to email or messenger.

What is included in the work:
— analysis of your current price list and pricing logic;
— selection of size, technique, number of animals, urgency and frame in a single interface;
— automatic price and deadline recalculation in real time without page reload;
— adaptive layout for phones and tablets;
— form for sending a request with the final calculation to email or messenger;
— price settings file available for independent editing;
— brief instructions for making changes to rates.
