Approach

Keep your tax work, supporting records and the reasons behind each decision together.

Tax lives in too many places.

  • Workings sit in spreadsheets, support in PDFs and decisions in email. Import records, customs plans and related-party agreements are kept apart from the books. Reconciliation takes months, and transfer pricing is left until year end.

  • A question from the tax authority, an auditor or management means pulling figures and papers from many files and inboxes. Much of the answer depends on who still remembers.

  • Tax positions and their workings are rebuilt each year in new spreadsheets, often by different people. Last year’s reasoning is hard to find, so the same work is done again rather than done better.

The platform

How Setoff TaxOS, Protas and Jetbooks work together.

Every obligation on one board

Tax rules, permissions and workflow for every entity and jurisdiction.

The Cycles register in Setoff: every tax year of each Diamond Mining Group company, with its next due date, status, returns filed and exposure in KES.

Solutions

Five modules on one engine.

Hold compliance to a high standard, cut penalty risk and keep every decision on file when people leave. Your consultant works here too.

  • All tax typesTax auditMeet every tax audit prepared, with evidence requests, reviews and sign-offs managed in one workflow from planning to close.
  • VAT · PAYE · WHTMonthly returnsClose every month with VAT, payroll and withholding tax reconciled to your ledgers, filed on time, and every supporting document tracked.
  • OECD · LocalTransfer pricingKeep transfer-pricing documentation current all year, track intercompany agreements and flag exposures early.
  • HS codesCustoms taxesTrack shipment duties and every customs document, flag risk in each import declaration, and stay ready for post-clearance audits.

Setoff’s modules run on a proprietary cycle ledger and a rules engine, so a new jurisdiction means new rules, not a new module. The rules engine follows OECD standards and fits common-law tax systems; customs work follows the World Customs Organization standards that most customs declarations share.

Control

Nothing moves without the right person.

Security

Access to company records is controlled by assigned roles and permissions.

All security controls
  • 01Company records kept apartEach session belongs to one company, every request is checked against the person’s permissions, and the database returns only that company’s records. People and AI agents pass through all three checks.
  • 02Single sign-on (SAML)Sign in through Okta, Microsoft Entra ID or any SAML 2.0 provider, with your own two-factor rules. Users not on SSO sign in with an authenticator app or a security key.
  • 03Secure AWS infrastructureSetoff runs on AWS, with data encrypted at rest and in transit. You can also bring your own storage, so documents stay in an account you own, in the region your regulators require.
  • 04Locked to your networkAllow sign-in only from your office, VPN or data-centre IP ranges. Attempts from anywhere else are refused, even with valid credentials.

Integrations

FAQ

What teams ask before they start.

Whether you need AI agents, which jurisdictions are covered, where to start when the books are a mess, and how the plans work.

What is Setoff?

Setoff is the operating system for tax operations: one engine of tax rules, permissions and workflow that your team runs in TaxOS, that Protas agents run with the same controls, and that Jetbooks gets your books ready for.

How do TaxOS, Protas and Jetbooks fit together?

TaxOS is the engine and the workspace your team uses. Protas is a set of AI agents that do tasks inside TaxOS with the same permissions. Jetbooks is a one-off job that rebuilds messy records into books TaxOS can run on.

Do we have to use AI agents?

No. Your team can run everything in TaxOS. Protas agents can take on preparation work when you are ready, and nothing is filed without a named approver.

Which jurisdictions does Setoff cover?

Setoff covers jurisdictions across ECOWAS, EAC and SADC, with rules, forms and deadlines set per jurisdiction.

Where do we start if our books are a mess?

With Jetbooks. It rebuilds the books from whatever records exist, traces every entry to its source and loads the result into TaxOS.

How do the plans work?

You pay per person. Specialist is priced per module each person uses; Enterprise covers every module, from five people; Managed Enterprise adds a quoted fee for Setoff’s data work, includes Jetbooks and is billed annually. Each plan covers one company, with a discount for each further company in the same country.

What costs extra, and how do we start?

Extra AI tokens come in packs of 100K, and onboarding, data migration or deployment can carry a one-off fee. On Specialist and Enterprise, a Jetbooks job is quoted on its own. Book a demo and we follow it with a written quote that lists every cost.
