The accountant

Gets the bookkeeping copy and the KPO book. Record payments as they arrive.

Hours get logged as you go.

Start the timer when you begin and stop it when you finish, on a computer or a phone. Every entry goes to a client, project and task, so at month end it is clear what gets billed to whom.

Timer or manual entry: Forgot to start it? Correct the start time or add the hours later.
Work, breaks and time off: Breaks and time off are logged but never end up on an invoice.
Month calendar: A dot under a day means time was logged, so gaps show at once.
Weekly hours: Everyone sees how much they worked this week against their working hours.
Unbilled this month: The hours and the amount waiting to be allocated, right on the home page.
Team reports: Who worked how much, by client, project and day.

Here's what it looks like.

Real screens from the app, on a computer and on a phone. The companies and clients are made up; everything else works just like this.

Allocate time September's hours for Acme GmbH, split across three companies: the two paušal ones fill up to their limits and the rest goes to the VAT-registered company. One click creates three invoices. Limits How much each company has invoiced this year, how much is left of the 6 million and when it will be reached at this pace. Invoice An issued invoice with its payments, corrections through credit notes, and a PDF for the client and one for bookkeeping.

Numbers Deoba keeps an eye on for you.

6,000,000 RSD¹: The annual flat-rate limit, for each company. Warnings at 80, 90 and 95 % and an estimate of when you'll reach it, so you can plan the move to bookkeeping or an LLC in time.
8,000,000 RSD¹: The VAT registration threshold over the last 12 months, for companies outside the VAT system.
70 %¹: The largest client's share of a sole proprietor's revenue, for the independence test.
01/2026: Invoice numbers without gaps, for each company separately, starting over every January.

Your accountant gets what they ask for.

Every invoice has two PDFs: one for the client, in their language, and one for bookkeeping, always with the NBS middle rate and the amount in dinars.

The KPO book for flat-rate companies, as the PDF form
Revenue invoiced outside Deoba counts toward limits and the KPO
All your data in one click, as a ZIP

A real KPO book from Deoba: ten entries for 2026, with the total turnover — Real PDFs from the demo account, in Serbian as your accountant needs them: the bookkeeping copy of an invoice and the KPO book.

The real bookkeeping copy of invoice 02/2026: EUR 4,259.50, the NBS middle rate and the amount in dinars — Real PDFs from the demo account, in Serbian as your accountant needs them: the bookkeeping copy of an invoice and the KPO book.

To SEF in one click.

When an e-invoice is required, Deoba sends it to SEF as soon as you issue it, with your company's API key, and the buyer gets it in their SEF inbox, with no email. Before sending, it checks that the buyer has an account. The same goes for advance invoices, credit and debit notes and cancellations.

Which invoices go to SEF, by your company and the buyer
	Domestic buyer	Public sector	Foreign client
VAT payer	SEF the buyer gets it on SEF	SEF the buyer gets it on SEF	PDF you send the PDF
Paušal	PDF you send the PDF	SEF the buyer gets it on SEF	PDF you send the PDF

SEF: Deoba sends the invoice and the buyer gets it on SEF, so no email is needed. PDF: you download it and send it from your company's address, as before.

Questions before you sign up.

How much does it cost?

Nothing while the beta lasts. We'll announce paid plans at least 30 days ahead, and you can download your data whenever you like.

I only have one company. Do I need Deoba?

It works with one: time tracking, invoices, the limit and the KPO book. But it's built for the day a second company comes along.

How is the flat-rate limit counted?

By what's invoiced, not what's collected. An invoice counts in the year the work was done (the turnover date), a storno lowers the year it's made in, and foreign-currency invoices at the NBS middle rate on the turnover date.

Does Deoba send invoices to clients?

When the invoice goes to SEF, yes: the buyer gets it in their SEF inbox as soon as you issue it, with no email. Other invoices, no: you download the PDF and send it from your company's email address, so the client gets it from the company that issues it.

Some of this year's revenue was invoiced outside Deoba. What now?

Add the company's earlier revenue on the Limits page. It counts toward the limit, and with the invoice number and date it goes into the KPO book too.

Does Deoba send invoices to SEF?

Yes, when it's required: for VAT-registered companies invoicing domestic buyers, and for public-sector buyers. The invoice goes to SEF when you issue it, with your company's API key, and so do advance invoices, credit and debit notes and cancellations.

Honest about the beta.
