What do we fix?

Got a summons from the tax office?

Don’t panic. We’ll check what the summons is about, prepare a response, and represent you before the office. If needed, we’ll correct declarations, clarify doubts, and minimize the risk of a penalty. In most cases everything can be settled without a fine.

Your previous accountant disappeared or stopped responding?

Unfortunately, this happens more often than you might think. In such a situation there’s no point wasting time and nerves — you can safely move your accounting to our office. We’ll ensure a smooth handover of documentation, contact with the authorities, and a clean-up of matters left by the previous accountant. We work on time, transparently, and are always available — by phone, email, or online.

Is your paperwork a mess, or missing entirely?

In many companies documents are “somewhere in the emails” or scattered across several folders. We bring it all together, create a secure electronic document workflow, and make sure nothing is missing. We put things in order once and for good.

Do you have arrears in VAT, CIT, or ZUS?

We know the procedures and the realities. We’ll help you prepare applications to pay in installments, file overdue declarations, and tidy up your tax history. We negotiate with the authorities. We can also apply for a write-off of interest or enforcement proceedings.

Missing records or errors in the books?

We fix incorrect bookings, make corrections, rebuild VAT registers, and analyze the consistency of invoices and transfers. If needed, we consult a lawyer or a certified auditor. Our goal is a clean account and peace of mind.

Have data in another system and don’t know how to move it to Optima?

We migrate databases from accounting software, CRMs, or custom systems without losing information. We use our own REST COM API modules, making the process fast, secure, and fully automatic. We can also connect current data sources (e.g. an order panel or WMS) with Optima.

About us

We are a well-coordinated team of accountants, analysts, and specialists who combine experience in accounting, financial analytics, and tax and business advisory — all so you can sleep soundly while your business grows without stress from the authorities. We specialize in difficult cases: we tidy up documentation left by previous accountants, handle KSeF, VAT, PIT, and CIT, and support you in day-to-day settlements and tax planning. We work with legal and tax advisors, giving you access to expert knowledge without the cost of permanent employment.

A partnership on your terms

We talk like humans, without bureaucratic jargon — we explain the numbers and the rules as if you were our business partner. We’re available by phone, email, or online, we respond instantly, and you focus on growing your company instead of chasing deadlines. We take full responsibility for the processes, contact with the authorities, and monitoring changes in the law.

Modern and efficient at every step

We rely on digital tools: a secure document workflow through mobile apps, automated settlements, and up-to-date reports available 24/7. Less paper, faster decisions, lower costs — organized data helps you in talks with your bank or investors. Many clients came to us after problems with previous offices and stay for years.

  • This is a service for companies that inherited a mess in their documents or settlements. We carry out a full audit of your accounting situation, identify errors in records, declarations, and settlements, and then make corrections — from clearing arrears to explanations before the authorities. Once everything is in order, you have a clean slate, up-to-date financial data, and confidence that the past won’t weigh on your business.

Comarch Optima integration via COM API

We offer an advanced service integrating the Comarch Optima system with your external tools (e.g. an online store, order panel, or WMS system) via COM API.

This solution enables automatic synchronization of key data – orders, invoices, inventory levels, prices, and counterparties – without the need to re-enter data manually.

  • Migration of your entire database to Comarch Optima.
  • Automatic integration with your current systems (store, warehouse, CRM).
  • Real-time synchronization – always up-to-date data.
  • Streamlined work for the accounting and operations departments.
  • Fewer errors and time savings.

How does it work?

1. Analysis of the client’s current database and system.

2. Preparation and deployment of REST COM API modules.

3. Data migration and validation.

4. Continuous synchronization and the option to automate further processes.
