Solvimon vs your home-built billing

Choosing billing infrastructure that grows with your business.

Overview

You built your own billing. It worked until it stopped supporting you.


An engineer writes a script that generates invoices, connects it to Stripe or Adyen, and moves on. It works for 18 months.

Then you add usage-based pricing. Then a second entity. Then an enterprise customer with a custom contract. Then AI features with variable inference costs.


Now you have 2-3 engineers maintaining billing code instead of building product - and that means you scaled past what billing v1 was designed for.

The billing tax

What your home-built system actually costs.

What you see

Feature

What it costs you

What it costs you

2-3 engineers maintaining billing code

~$1M/year in fully loaded costs (people + opportunity cost)

2-week month-end close cycles

Pricing changes blocked behind engineering sprints

Engineering sprints diverted to billing fixes

Enterprise deals delayed by billing limitations

Manual reconciliation between systems

Revenue leakage from manual processes. We often see 5-10% undetected in home-built systems

Most companies don't measure the billing tax because it's spread across engineering, finance, and ops. It shows up as slower hiring, slower launches, and slower closes (not as a line item).

Maintained by engineers who'd rather be building core product

At $10M in billed revenue, Solvimon costs $40K/year. Your home-built system costs your best engineers.

Built for AI

Variable inference costs need variable pricing infrastructure. Stripe Billing has no native concept of credit wallets, token burn-down, or multi-pivot rate cards. Solvimon does:

Hybrid pricing models

Bill seats, usage, and credits in one ledger. No separate systems to reconcile. Configure pricing as your product evolves.

Multi-Entity Native

Launch new geographies without new accounts. One system handles invoicing across all entities with proper tax calculation and compliance.

Credits & Tokens

First-class credits with burndown, rollover, and multi-pivot rate cards. Handle different resource types (API calls, agent runs, image generation) with different economics.

Why Solvimon

Helping AI businesses reach the next level

The Solvimon platform is extremely flexible allowing us to bill the most tailored enterprise deals automatically.

Ciaran O'Kane

Head of Finance

Solvimon is not only building the most flexible billing platform in the space but also a truly global platform.

Juan Pablo Ortega

CEO

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

Working with Solvimon is a different experience than working with other vendors. Not only because of the product they offer, but also because of their very senior team that knows what they are talking about.

Steven Burgemeister

Product Lead, Billing

Our billing works fine. Why would we switch?

Ask your engineering team how many hours they spend on billing. Ask finance how long month-end close takes. If the answers are "too much" and "too long" that's the signal.

Can we migrate incrementally?

Yes. Run Solvimon alongside your existing system. Migrate customer cohorts, not the entire base at once. No big-bang cutover required.

What about our custom logic?

Solvimon's contract engine handles custom pricing, commitments, and deal-specific terms. The logic in your orchestration code today becomes configuration.

How long does implementation take?

Depends on complexity. Typical: 4-8 weeks. The migration is a one-time investment. The billing tax is ongoing.

What if we need something you don't support?

Talk to us. We built Adyen's internal billing. We've handled edge cases at €970B+ in annual volume. Your edge case is probably a pattern we've seen before.
