Evolv Accountants, a South African accounting and advisory firm, runs its client entities, SARS and CIPC compliance, UIF declarations, salary schedules, inbox and tasks on AtlasOS, the practice platform that Arke Technologies (Pty) Ltd owns and builds in Johannesburg. Evolv is the AtlasOS reference site.
An accounting and advisory practice carries its clients' deadlines as well as its own: income tax, VAT and PAYE with SARS, annual returns with CIPC, provisional tax, UIF declarations and salary schedules. Each client may be a group of related companies, trusts and individuals, and each entity keeps its own calendar.
When that work lives in spreadsheets, diaries and email folders, the people running the practice see the portfolio only by asking around, and a missed deadline tends to surface when a client or SARS raises it. Evolv describes the gap in its own words below: before AtlasOS, it did not have visibility across its entities.


Atlas OS gives us visibility across 89 entities that we simply did not have before. The compliance tracking alone has saved us significant time every month.
Evolv Accountants is our sister company. We state it so that you can weigh the evidence, and judge AtlasOS yourself in a demo.
Evolv is both the validation environment for AtlasOS and the reference architecture for every deployment that follows. New capability is proven in a working practice, against real SARS and CIPC deadlines.
That matters because practice software fails in the details: a deadline rule that is wrong for one kind of entity, or a task flow that does not match how a firm signs off its work. A working practice exposes those details every day.
AtlasOS is configured by profession. It is live for accounting and tax practices in South Africa, for audit and assurance firms in South Africa and for payroll bureaux, and it is available for nonprofits; legal practices are in scoping.

A practice holds identity numbers, tax numbers and payroll records for every client, so the architecture matters.

AtlasOS is the operating system for professional services firms, owned and built by Arke Technologies in Johannesburg. It brings client and entity management, SARS and CIPC compliance workflows, AI-assisted advisory, billing, a client inbox and firm branding into one platform, with each firm's data isolated at the database level. Visit the AtlasOS site (opens atlaspractice.app) for full product detail.
AtlasOS pricing is available on request after a demo, and is not published on this site. We first need to understand your firm, the entities you carry and the compliance work you do for clients. Book an AtlasOS demo through our contact page, or visit the AtlasOS site (opens atlaspractice.app) for product detail.
No. Evolv Accountants is our sister company, and we say so to let you weigh the evidence fairly. Evolv runs its compliance work, tasks and inbox on AtlasOS and is the reference site for the platform. The most useful test for your firm is a demo against your own workflows, entities and deadlines.
Yes, with people in charge. The AI-assisted advisory module lets staff ask plain questions of the practice's data, such as overdue tasks, compliance risks and client summaries, and it supports decisions without replacing judgement. We never train models on client data without explicit consent. Our page on how we use AI sets out the limits.
