Payment-processor planner

Reviewed Skip to the planner

Sellers choosing a card processor. The decision this page isolates is narrow on purpose: translate monthly volume into a processor class. Seats, volume, and included limits usually decide the class before a brand name does.

This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank Square and Shopify. It produces an explainable class so Square Payments and Shopify Payments can be compared as examples of that class.

The working method is: Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. Planning notes are grounded in Square. This page does not quote a price or rank a brand.

How to use this calculator

Sellers choosing a card processor. Translate monthly volume into a processor class. If you can answer monthly card volume in thousands, this page can produce a class you can shop against.

What this page will not do

  1. Enter the planning inputs

    Choose a processor class by recording monthly card volume in thousands. Use real measurements or counts, not a rounded marketing number.

  2. Keep optional extras off until they are real

    This tool has no optional add-ons. If a number is uncertain, calculate a range and keep the more conservative class.

  3. Read the planning class

    Calculate class and treat the headline as a class, not a product name. Matching examples below follow Starter, Growth, and Advanced.

  4. Compare official pages, then verify

    Open the official page for each example in that class. Confirm current specifications, dimensions, and terms. Decision Lantern does not quote a live price or complete an install review.
