Main differences between ABRA Aiva and ABRA Flexi
ABRA Aiva is a comprehensive ERP system that adapts to a company's processes, including custom modifications. ABRA Flexi is an accounting and business system built around a quick start, standardized processes, and cloud operation. For many companies this means less effort spent on system administration and lower costs, but it is important to know where the two systems differ.
Area | ABRA Aiva | ABRA Flexi |
Operation | installation on your own server or the ABRA online service | cloud in Amazon Web Services data centers in the EU; running on your own server is also possible |
Working with the system | primarily a desktop application | web application in a browser (including on tablets and mobile phones), with an optional desktop application for Windows, Linux, and macOS |
Updates and backups | by agreement and depending on your own operation | in the cloud, regular and automatic; we take care of backups and security |
Licensing | based on the selected modules and system configuration | monthly or annual subscription per user who actively works in the system, in three plans |
Inventory prices | calculated at warehouse closing | calculated continuously, as soon as an inventory document is created |
Customization | custom modifications, workflows, extensive parameterization | labels, user relations, configurable print reports, ready-made add-ons, and an open REST API |
When to consider the switch carefully
⚠️ If you use extensive custom modifications, approval workflows, more complex manufacturing, or specialized modules in ABRA Aiva, we recommend discussing the switch with a sales representative first. Together we will verify how your processes can be covered in Flexi and which add-ons or API integrations may be needed.
Licenses and pricing
ABRA Flexi licensing is simple and predictable:
You pay only for active users. Paid access is required for everyone who enters data in the system (issues invoices, posts entries, works with inventory).
Read-only users are free, in unlimited numbers.
Unlimited number of companies and documents within a single license.
Monthly or annual subscription. With annual payment you get one month free.
You can change your plan at any time in the application, in the Licenses and subscription section.
The plans differ in the scope of features. Choose based on which ABRA Aiva modules you will need in Flexi:
Plan | Who it's for | What it includes |
Basic | sole proprietors and small companies without employees | accounting and tax records, invoicing, inventory, bank and cash register, assets, cost centers |
Business | small and medium-sized companies with employees | everything in Basic, plus payroll and HR, quotes, inquiries, orders, projects, price list tree, Excel imports, payment reminders, point of sale, batches and expiration |
Premium | medium-sized and larger companies, accounting firms | everything in Business, plus FIFO inventory valuation, warehouse locations, bill of materials, contracts and recurring invoicing, Intrastat, EDI, user queries, and custom reporting |
Current prices for each plan, API access, extended support, and services can be found in the ABRA Flexi price list. Prices are shown excluding VAT.
ℹ️ In addition to the license, also factor in the data migration. It is performed by our consultant at an hourly rate according to the price list, typically 4 to 8 hours per accounting entity, depending on the volume of data. REST API access and extended support (phone support, faster response) are optional purchases.
What we migrate from ABRA Aiva
For the transition, we have prepared a migration bridge that transfers code lists, the address book, opening balances, and document history. The Cooperation during migration section describes what we will need from you for the migration.
⚠️ The migration is not a 1:1 copy of your accounting. Accounting in Flexi continues from opening balances, paid documents are transferred as non-accounting history, and unpaid invoices are transferred as remaining amounts due. As a result, for example, individual accounting entries, inventory movements, payroll, assets, as well as inquiries, quotes, and contracts, including their code lists, are not migrated. We therefore recommend keeping ABRA Aiva as read-only, for example for tax authority audits.
Cooperation during migration
To make the migration go smoothly, we will need the following from you:
A backup of your company data from ABRA Aiva version 23.1 or later.
An activated ABRA Flexi license and a newly created company into which the data will be loaded.
ABRA Flexi access for the consultant who will perform the migration. You will set up a user account for the consultant in the new company.
ℹ️ Large data volumes. For companies with tens of thousands of invoices (on the order of 10,000 to 100,000), the import can take several hours and must run without interruption the whole time. We therefore schedule the migration with a sufficient time buffer.
⚠️ During the migration, do not work with data in ABRA Flexi, meaning do not create or edit any records until the consultant confirms that the migration is complete. Concurrent changes may disrupt the import.

Cash receipts, Cash disbursements | as non-accounting history | |
Chart of accounts (opening account balances) | opening account balances are created by an internal document, and for cash registers and bank accounts by opening movements; see setting up opening account balances |
ℹ️ How opening account balances are created: For example, if account 311 (Receivables from trade relations) has an opening balance of CZK 1,000 on the debit side and CZK 500 on the credit side as of the transition date, the migration creates an internal document with two lines, one for each side. Opening balances of cash registers (accounts 211) and bank accounts (accounts 221) are not created by an internal document, but by opening movements directly in the cash register and bank.
What is not migrated and how to handle it in Flexi
The migration bridge does not transfer certain areas. However, you can easily set them up in Flexi, often in bulk using Excel import.
Area | How to proceed in Flexi |
Payroll and HR | create employees and payroll data in Flexi; the procedure is described in the article How to get started with payroll (from the Business plan) |
Assets | create asset cards, including existing depreciation, by following the asset records guide |
Inquiries and quotes | Received inquiries, issued quotes, and other sales documents, including their code lists (from the Business plan) |
Contracts | recurring invoicing is handled by customer contracts (Premium plan) |
Manufacturing | simpler manufacturing and assembly is covered by a bill of materials (Premium plan); for more, see the We manufacture guide |
Accounting entries | only opening account balances as of the transition date are migrated; you can look up individual accounting entries from past periods in ABRA Aiva |
Inventory movements | only opening inventory balances are migrated; you can look up the movement history in ABRA Aiva |
Reports and print layouts | use the ready-made printouts and the configurable report editor; we can prepare custom-made layouts for you as a service |
Get started based on your type of business

Connecting to other applications via the REST API
ABRA Flexi offers an open REST API through which you can read and write data in practically all records, such as invoices, the address book, the price list, inventory documents, or the bank. It supports XML, JSON, and CSV formats and also allows exporting print reports to PDF. You can use it to connect an e-shop, a CRM, an inventory system, or your own applications.
API access is purchased separately from the license; for details, see the article API access licensing.
The daily request limit depends on the license plan; for the Business and Premium plans, the limit can be increased.
Ready-made integrations with banks, e-shops, and other services can be found among the ABRA Flexi add-ons.
Where to start:
API communication made simple for non-IT users explains what an API is and how to enable it in Flexi
How to get started with the Flexi API is a six-part series for developers, from logging in to XML and JSON examples

How the transition works
Inquiry and consultation. Send us an inquiry, and together we will review your processes and recommend a suitable license plan.
Trial. You can try ABRA Flexi free for 30 days, and the trial version converts seamlessly to a paid one once you place an order.
License and company setup. A new company is created in Flexi, into which the data is migrated.
Backup from ABRA Aiva. You prepare a backup of your company data from ABRA Aiva version 23.1 or later.
Data migration. The consultant migrates the data using the migration bridge. Do not work with data in Flexi until they confirm completion.
Finishing the setup. You review and complete the company settings, users, and their permissions, and connect your bank or e-shop as needed.
💡 The easiest approach is to switch at the start of a new accounting period, but the transition is possible at any time during the year. For a quick start, we recommend individual training focused directly on your processes.
Frequently asked questions
Do I have to cancel ABRA Aiva after the transition?
We recommend keeping ABRA Aiva at least for read-only use. The migration does not transfer the complete accounting history, and your original data will come in handy for audits or for looking up older documents.
Will unpaid invoices be migrated too?
Yes. Unpaid issued and received invoices and advance invoices are migrated with the remaining amount due, so you can match them with payments in Flexi as usual.
Will I have to install an application for Flexi?
No. When running in the cloud, you work in the web application in your browser. You can use the desktop application alongside it, but some features differ between the two interfaces.
How many user licenses will I need?
Paid access is needed only by those who actively work in the system. Colleagues who only view the data can have read-only access for free.
How long does the migration take?
The consultant's work itself usually takes 4 to 8 hours per accounting entity. We schedule the migration so that it disrupts your operations as little as possible.
