Pricing migrations and billing reconciliation

Done by someone who's seen what breaks.

When SaaS companies move from per-seat to usage-based, introduce hybrid pricing, or discover their Stripe and CRM data don't reconcile, the engineering work is rarely the hard part. The hard part is the operational complexity nobody scoped:

Grandfathered plans
Entitlement drift
Finance reporting that no longer ties out
Customers on contracts written before the new model existed

I'm Tomas. 20 years as a senior engineer and architect, the last 3 spent specialized in SaaS billing — Stripe, pricing migrations, entitlements, the operational reality between billing systems and the rest of the business. I do two things: pre-migration risk assessments and billing reconciliation audits. Fixed scope, fixed fee, named deliverables.

How an engagement runs

30-minute scoping call. We confirm fit, scope the work, agree on dates. No pitch deck, no follow-up dance.
Two to three weeks of focused work. I work against a written brief. Your team provides access and answers questions; I do the analysis.
Deliverable and readout. You get the written deliverable and a 90-minute leadership readout. Then we're done. No retainers, no scope creep, no ongoing dependency.

Not sure which fits?

Book a 30-minute scoping call. I'll tell you which engagement maps to your situation, or whether neither does. Fee, timeline, and start date are confirmed on the call.
