About Sengi

The story of the Sengi team began with the concern of one of the main members of the team to manage the finances of self-employed individuals and freelancers, and given the background we had in managing personal finance. Today, after almost 5 months, it has become a 24-hour concern of all members of the Sengi team. In the first days of 2022, our team released the first version of its new product called Sengi Business Management. The need for this product was identified during the 5 months of experience of the Sengi team in the personal accounting application, and both products are available today. We try to produce the financial management solution in our two products in the simplest possible way, which is very practical and user-friendly.

Most solo professionals lose money without realizing it

You send invoices.
Clients pay.
Revenue looks fine.

But underneath:
- Fixed-fee projects quietly expand
- Scope creeps in without warning
- You only notice the problem when the project is already unprofitable

Traditional invoicing tools record the past.
They don’t protect your margins.
