Nersa owns and uses proprietary accounting software programs for client bookkeeping and supervision, and accountants can travel to client premises when needed.

The business model is professional services-based, with revenue generated through fee-based, quote-based engagements tailored to client needs, billed on a pay-as-you-go basis. Go-to-market is sales-led, relying on referrals, organic web presence, direct phone/email outreach, and content marketing. The firm offers no software-as-a-service products, has no technology platform beyond internal accounting tools, and has no external investors, funding, or publicly disclosed financial information.
