Avonni LWC Components

Compare the cost of custom LWCs and Avonni.

Estimate development, ongoing maintenance and subscription costs using assumptions you can change.

Estimate your project

Adjust the example values to compare building your own components with using Avonni.

Example values, not benchmarks. Internal use in one Salesforce production org.

Your project

Define the same project for both options.

Count distinct components your team needs to build or integrate: for example, a deal table, a planning calendar and a Kanban board = 3. Count a reusable component once; include additional integration work in your effort estimate.

Use your team's average hourly cost or your contractor's hourly rate. The same rate applies to work on both options.

Choose the number of years to compare. Both totals include initial work and ongoing costs over this period.

Count the people who build or use pages, Flows or apps containing Avonni components, not everyone in your Salesforce org.

Option A: Without Avonni

Your team builds, tests and maintains its own components.

After AI: 48 hours per component

Assumed time saving: 60% Adjust

Estimate hands-on development and testing time, not elapsed delivery time. One week means 40 working hours. Use an average across the components in your project.

Allow for release testing, bug fixes and ongoing changes. For example, 15% of a 120-hour build means 18 hours per component each year, before any AI reduction. For your project: 144 h a year before AI.

Option B: With Avonni

Your team integrates Avonni components. You maintain your integration; Avonni maintains the package.

After AI: 2.4 hours per component

Assumed time saving: 60% Adjust

Your team's time to integrate, adapt and test each Avonni component, including surrounding LWC or data code. This work is separate from the subscription.

Your team's time to test upgrades and maintain your integration and business-specific changes. Avonni maintains the package code.

Plan for the number of people above: Pro

Up to 10 people: Free. 11 to 75: Starter. 76 to 150: Pro. Over 150: Enterprise.

Pro list price: $10,800 a year ($900 a month, billed annually). Replace it with your quote if you have one.

AI time savings

Apply estimated time savings to both options. They do not reduce subscription costs.

60% means 100 hours becomes 40. If your estimates already include AI savings, set this to 0% to avoid applying the reduction twice.

Apply a separate reduction to annual maintenance on both options. Leave this at 0% if you assume no saving or your maintenance estimates already include AI.

Estimate over 5 years

Avonni costs less, by about

$56,976

Over 5 years: custom LWCs $132,480, Avonni $75,504 (Pro subscription included). An estimate from the assumptions shown, not a guaranteed saving.

How the estimate works

Components are counted once each: a component reused on several pages is not a new full build, and any extra integration work belongs in the effort estimates.

Without Avonni, your team builds custom LWCs. Initial work is components × build weeks × 40 hours, reduced by the time saved with AI on initial work, × your rate. Annual maintenance is the maintenance percentage of the original build hours, before AI, reduced by the time saved with AI on annual maintenance, × your rate.

With Avonni, your team integrates the components. Integration is components × integration hours, reduced by the time saved with AI on initial work, × your rate. Annual maintenance is components × maintenance hours, reduced by the time saved with AI on annual maintenance, × your rate. The subscription is the annual amount × years.

Each total is initial work, plus annual maintenance × years, plus the subscription × years. Each AI reduction applies once, to one set of hours, and never to the subscription. Each line is rounded to the dollar and totals add the rounded lines.

Assumptions

The starting values are examples, not benchmarks: they are not measured averages and have not been validated on customer projects. Avonni maintains the code of its managed package; your team still integrates, adapts and tests each component, which the integration and maintenance hours cover. Prices, rates and license count are assumed constant over the period.

Avonni prices used

List prices on avonni.app/pricing, read October 14, 2026, in USD before tax, billed annually. Up to 10 licenses: free, no time limit. Starter: $6,000 a year, up to 75 licensed users. Pro: $10,800 a year, up to 150. Enterprise: from $1,300 a month ($15,600 a year), priced on the number of people you license, so the estimate needs your quote. The calculator does not deduct the 10 free licenses from a paid plan.

Not included

Salesforce licenses and the work both options share, such as design, project management and training. Taxes and discounts, including nonprofit pricing. Experience Cloud portals, guest access, several production orgs and ISV or OEM use, which are quoted separately.

Before you quote it

This is an estimate from the inputs above, not a quote and not a guaranteed saving. It can favor custom LWCs, for example with few components, a short period or large AI time savings.
