Serve all your clients from one account
The Office Panel in Mobilna Faktura — a single client list, one-click access to a client's account, KSeF, KPiR and the lump-sum tax, ZUS and PIT returns, HR and payroll. The panel is free, you only pay for the clients you maintain at the office's cost.
For offices serving sole traders, lump-sum taxpayers and companies on KPiR
Why accounting offices choose Mobilna Faktura
Earn 30% on referrals
A client who signs up through your referral link means 30% commission on their subscription for 24 months. Your balance and the list of referrals are in the panel, with payouts from 50 zł.
Win clients from the office directory
When you register you tick a consent box and your office is listed in the directory of accounting offices on ksiegowosc24.pl — right where business owners look for an accountant.
All your clients from one account
A single list of the companies you serve, with a month and year filter. For each client you see their NIP and the number of sales and cost documents in the selected period.
One-click access to a client's account
The "Enter" button switches you to the client's account and gives you that company's full panel — with no separate login and no need to remember passwords to dozens of accounts.
Hand the data over to your own accounting software
Bulk export for many clients at once: a ZIP package in the format of InsERT Rewizor and Rachmistrz, Comarch ERP Optima, WAPRO Kaper and Fakir, RAKS SQL, Symfonia FK, enova365, Streamsoft Ala or Mała Księgowość RP — with import instructions inside.
The assistant knows your clients
In the panel and over MCP (Claude, ChatGPT) the assistant lists your clients, their taxes for the month and the documents flagged for clarification, and changes the status of a month — always after you approve it. For a client's purchases a suggested KPiR column is already waiting, and next to every client you see how many recurring invoices are still missing this month.
KSeF in every plan, at no extra charge
Every client has their own KSeF authentication. Sending invoices, KSeF numbers, UPO confirmations and importing purchase invoices — including in the client's free plan.
Pay for as many clients as you serve
The Office Panel is free. You only buy a company pack for clients whose accounts you maintain at the office's cost — the rest do not use up your pool.
What working with a client looks like — step by step
No implementation project and no training. You set up an office account in a few minutes and add your clients gradually.
- 1
You set up an office account
Register under "Create an office account". Once logged in, "Office Panel" appears in the menu. No implementation project and no upfront fee.
- 2
You add or invite clients
You create an account for a client from the panel or e-mail an invitation to an existing account — the link is valid for 14 days, the client accepts it and the accounts are linked.
- 3
You decide who pays
For each client you choose "at the office's cost" or "the client pays themselves". The second option does not use up your pool of companies.
- 4
You split clients between your staff
The office owner grants each accountant access to specific companies. By default a member of staff sees no clients at all.
- 5
You work and tick the month off
You enter the client's account, post the documents, file the returns, and on the list you mark the status: To be settled, In progress, Posted. Purchases with no KPiR column assigned come with a ready suggestion — you accept it or correct it.
What your client gains
The office sells this solution on — which is why the client also needs a reason to move to Mobilna Faktura.
- ✓ Issues invoices from a phone, tablet and computer — without installing anything
- ✓ Sends invoices to KSeF from their own account, with a KSeF number and UPO
- ✓ No longer carries documents to the office — you both work on the same data
- ✓ Receives e-mail reminders about ZUS, VAT and PIT deadlines
- ✓ Gets a free plan to start with, and moves up only once they grow
For clients running a sole trader business, point them to the page for the self-employed — it explains the offer in their own language.

What it costs the office
The Office Panel is free — you set up an account and serve your clients with no upfront fee. A client with their own subscription does not use up your pool. You only buy a company pack for the clients whose accounts you maintain at the office's cost. Annual prices are net of VAT (the VAT-inclusive amount you pay in the panel is shown next to each), and packs add up.
10 companies
804.88 zł
per year, net · 990 zł incl. VAT
6.71 zł net / company / month
20 companies
1455.28 zł

5.41 zł net / company / month
100 companies

The bigger the pack, the cheaper per company — from 6.71 zł net at 10 companies down to 4.74 zł net at 100. Payment is online, and once it is credited your pool grows automatically. You buy a pack in the panel — see the Office Panel.
Earn money and win clients
30% commission for 24 months
Every account has its own referral link. For clients who create an account through your link you receive 30% of their subscriptions for 24 months. Your balance, the list of referrals and payout requests are all in the panel — payouts from 50 zł.
The commission applies to client subscriptions; it does not cover purchases of company packs.
Directory of accounting offices
When registering an office account you tick a consent box and your details are listed in the directory of accounting offices on ksiegowosc24.pl — right where business owners look for an accountant.
The listing is free and optional — you tick the consent box yourself when creating the account.
✅ Mobilna Faktura fits if:
- • you serve sole traders, lump-sum taxpayers and companies on KPiR, and keep limited companies on the Księgowość plan,
- • you want your clients in one panel, without collecting passwords,
- • your clients issue invoices themselves, often from a phone,
- • KSeF matters to you without paying extra for a higher plan,
- • you would rather pay for the number of companies served than for each licence,
- • you have your own accounting software and want to hand your clients' data over to it in a single export.
⚠️ Look for a different solution if:
- • you need to file returns in bulk for many clients at once — you calculate, generate and export in bulk, but each return is filed from the client's own account,
- • you require a ready-made import from a specific competing program (the other direction, export to nine programs, is covered),
- • your clients do not want to work in a browser — the Office Panel has no installed desktop version.
We would rather say this outright than have you find out after moving your clients across.
