Viktor Popovic rebuilt after 21 years running Ultimate Washer by creating Avendo, a platform that routes each merchant transaction in real time across multiple processors so the lowest price wins without any lock-in. The most striking detail is that he now charges processors only ten cents per successful transaction and nothing to merchants, a direct response to the opaque statements and stagnant rates he accepted for over a decade.
• After 14 years with one processor, Viktor saw volume grow while rates stayed fixed because statements were four to ten pages of line items that owners handed to accountants rather than challenge.
• Avendo collects one application and set of documents, then forwards them to multiple processors; once several underwrite the merchant, the system lets those processors bid live on every card transaction.
• The merchant dashboard shows only the final approved amount, statement, and chargeback tools; all routing logic, fallback decisions, and price responses stay hidden in the backend and complete in milliseconds.
• A queue was added after live testing showed that transaction logging, not authorization, created stalls; the two backend teams met, mapped the bottleneck, and inserted the queue so results could be written without blocking the flow.
• Weekly rotating tests now run across system segments to catch similar issues before they scale, because the architecture must duplicate cleanly for future markets such as Canada.
• Viktor’s prior experience with seven separate product databases taught him that disconnected tools force constant manual updates; Avendo’s teams therefore meet at least weekly to keep every new component on a single source of truth.
