Credit card processing for Seattle e-commerce sellers

Washington permits surcharging. The practical problem in Seattle is that cash usage is unusually low, so a cash-discount program has little behavioral effect — a surcharge or a straight interchange-plus restructure typically does more here. For a e-commerce business specifically, we would structure this as a surcharge or cash discount program sized against a $35–$400 average ticket. As of August 2026 that is our reading of the Washington position, and we re-verify it as part of every engagement rather than relying on a page like this one.

The only number worth comparing is your effective rate: total fees divided by total volume processed. For e-commerce sellers with a $35–$400 ticket and a card mix that is entirely card-not-present, the cost drivers are specific — missing or partial address verification data is the most common one we find. We derive your effective rate from three statements at no cost.

We are a Chicago practice and we work with merchants across the United States, Seattle included. Every engagement runs the same way regardless of geography — statements in, arithmetic out, in writing. One of the most card-heavy and cash-light markets in the country, which makes a cash-discount program less effective and a surcharge or interchange-plus restructure more relevant.

E-commerce sellers sit in an elevated-risk band. Most acquirers will write the category in Washington, but the underwriting looks closely at the specific exposures in this vertical, and a well-built file is what avoids a reserve.

Yes — all of our software is designed and built in Chicago. Sometimes. Subscription and wholesale hybrids frequently outgrow platform-native tooling. Builds are delivered with source code and full data export, with card, ACH and recurring billing embedded in the workflow.
