SEON grew fast. Their sales team had the freedom to structure deals however customers needed: usage-based pricing, custom thresholds, product bundles. That flexibility helped them sign hundreds of new customers in a short window.

It also created 700 unique pricing plans - which is a lot.

Finance managed all of them through one Excel spreadsheet. Sophisticated, yes. Sustainable, no. The spreadsheet calculated usage across products and features, then output invoices as PDFs. No line items visible to customers. No audit trail for finance. Just a monthly ritual that consumed more time as the customer base grew.

“I was skeptical if there was any solution out there that could relieve the team from an eternity of manual billing. Solvimon impressed me with their flexibility and user-friendliness.”

— János Mátyásfalvi, CFO

Challenge
SEON evaluated subscription platforms, open-source tools, dedicated metering solutions, and modern billing platforms. Most couldn't handle the pricing complexity without custom engineering. Building in-house wasn't viable—they needed to focus on fraud prevention, not billing infrastructure.

Solution
Solvimon was the only platform that could ingest all 700 pricing plans without workarounds. Built by the team that scaled Adyen's billing engine, we already understood usage-based pricing at volume. The migration took less than two weeks.

Within the first month live: 75% of invoices previously done by hand were fully automated. Revenue leakage (previously invisible in the spreadsheet) surfaced across 10% of invoices. Finance and commercial teams gained shared visibility into pricing definitions and deal structures.

The SEON team went live with Solvimon’s Integrated Metering, Pricing, Automated Invoicing capabilities, and HubSpot integration, completing their onboarding in just under 2 months.

Impact

“In terms of cooperation, I could hardly imagine a better example than what we have experienced. I am very glad to have chosen Solvimon as our partner.”

— Gergely Tolgyesi, Director of FP&A

The estimated impact: 5 FTE worth of manual billing work eliminated. Finance stopped managing spreadsheets and started managing growth.
