HOW WE WORK

A straightforward start.

A well-defined engagement helps everyone understand what happens next.

01

Understand

Tell us about the business, the immediate priorities and the support you need.

02

We confirm scope, information requirements, responsibilities, fees and timing.

03

Deliver

We carry out the agreed work and communicate issues and next steps clearly.

COMMON QUESTIONS

Before we get started.

Can we engage you for just one service?

Yes. You can discuss a specific assignment, such as a tax review, bookkeeping clean-up, payroll support or an audit. The agreed engagement letter defines the work.

Do you support businesses operating in Zanzibar?

Yes. Tell us where your activities, staff and transactions are located so the engagement can address the relevant requirements. Our office is in Dar es Salaam, and the guide distinguishes Mainland Tanzania from Zanzibar.

Can you provide both bookkeeping and audit?

We assess independence and conflicts before accepting an audit. Where the combination would compromise independence or breach applicable requirements, the scope or service provider must be changed.

How do we get a fee proposal?

Email a brief description of your business, the service required and any deadline. Fees and the proposed scope are agreed before work begins.
