02 / Questions
Frequently asked questions
- How do I start?
- Choose a plan, open an account and you have a 30-day free trial — no card required. You pay only once you decide to stay.
- Annual or monthly billing?
- Your choice, for every plan: annual billing comes with a lower monthly price (e.g. Kancelarija 23 € instead of 25 €). The features are the same whichever way you pay.
- How do the plans differ?
- By modules, never by quantity: Sveska is invoicing with SEF e-invoicing and the KPO income ledger, Knjiga adds received e-invoices, bank statements, VAT and e-delivery notes, and Kancelarija adds inventory, work orders, fixed assets, payroll and business trips. Everything a plan contains is unlimited.
- Is there a charge per invoice?
- No. Everything a plan contains has no quantity limits — invoices in every plan, and inventory lines in Kancelarija too. There are no volume surcharges.
- How many users can work in the programme?
- Sveska includes 1, Knjiga 2, Kancelarija 3 and Biro 3 users. On the Knjiga, Kancelarija and Biro plans each additional user is 5 € a month; an agency team in a client company linked through Biro does not use the client’s seats.
- Can I move to a bigger plan later?
- Yes, by yourself and at any time, directly in the programme: a bigger plan applies immediately with a prorated charge for the remaining days, a smaller one from the end of the paid period. Your data and documents always stay — only modules get unlocked or locked.
- What does support look like?
- Through chat in the app (Help → Chat), by phone on working days from 9 to 15 and by email. You see chat replies in the app, and if you are not in it at that moment they also reach you by email. Support is free and included in the subscription — there is no per-minute charge and no hourly training fee.
- How does my accountant work in duplo?
- You invite them to your team with the Accountant role — whether in-house or external. They see everything, keep the books through the Accounting add-on, and do not issue documents in your name; from a single account the same accountant works in every company that invites them, at no extra charge. If the accountant has the Biro plan, you LINK UP instead of sending an invitation: their team then does not use your user seats. More on the Accountants page.
- What is the Biro plan (Accountants tab)?
- The plan for accountants and agencies: Kancelarija + Accounting for your own firm, 3 users, 30 € a month billed annually (34 € monthly). You run client companies under the same subscription at 1 € a month per company (0,5 € from company 21 onwards) — each gets the whole programme. You open the company of a client who does not use duplo (the client has no access, only your team works in it); with a client who already pays for duplo you link up — your team keeps the books in their company without using their seats.
- What if my client already uses duplo?
- The company is not duplicated. From the Clients page you send a link request by PIB (tax ID); the owner of the client company accepts it and your team joins as Accountant — their plan, SEF key and people stay theirs, and the link costs the same as a client company (1 €/mo). If the client stops working on their own, with both sides confirming you take over running the company from the end of their paid period — on the same data, with no gap in the books.
- Can a client work in a company I run for them under Biro?
- In a company you opened — no: it has only the Accountant role, and nobody issues invoices in it except you as the agency owner; if the client wants to invoice and view data themselves, they register their own company (their own plan) and you link it up. That is why we ask first: will the client work in duplo themselves?
- What is the Accounting add-on?
- A bookkeeping layer over the documents you already keep: journal entries are created automatically from invoices, bank statements, payroll, inventory and imports and take effect immediately, the partner ledger and statement of open items are real-time, and the trial balance, general ledger and journal are available at any moment. 8 € a month billed annually (9 € monthly) on the Knjiga and Kancelarija plans, 30-day trial, in beta.
- What if I run several companies?
- A plan covers one company. Accountants and agencies run client companies through the Biro plan (1 € a month per company). A second company of your own (a holding) is registered on a separate account — the same person can be a member of several companies and switches between them in the header.
- What does “coming soon” mean?
- Features marked “coming soon” are in development and will be included in the plan at no extra charge as soon as they are ready. The price does not change because of them.
- Where is my data?
- In the European Union (Frankfurt), separated per company. You can export your data whenever you like, free of charge.
