Exchange positions via clipboard.

With GAEB-Online 2023 you can select items in the table and copy them via the clipboard (Ctrl+C and Ctrl+V) directly to Word, Excel, OpenOffice or to an eMail program such as Outlook.

GAEB-Online 2023 Positionen per Zwischenablage austauschen


With the BoQ filter, an BoQ can be filtered according to various criteria in a matter of seconds. For example, you can display only positions with certain short texts. Or you can filter special areas of the BoQ via the position number (OZ). All filters can be combined with each other, e.g. show me all positions in section "1" that contain "shaft" in the short text and have the unit "pcs".


DA84 by Mail

Offers generated with GAEB-Online 2023 in D84 format can now be sent directly from the program by e-mail. Here too, GAEB-Online 2023 automatically recognizes the correct format and sends the appropriate quotation file to the recipient.

Excel-Price requests

As an estimator, you know the problem. In order to complete a quote for a builder, you have to ask your building materials dealer for the prices of certain items. Of course you can call them and ask for the prices or send the BoQ by fax. It would be simpler to use GAEB-Online 2023, where you can use the BoQ filter in GAEB-Online 2023 to filter the items to be requested in the list and export them to Excel with a mouse click. You send the Excel spreadsheet by e-mail to your building materials dealer. He fills in the prices directly in Excel and sends the file back to you. You enter your surcharges in the table and import the supplier's Excel table with GAEB-Online 2023. The missing prices are automatically added and your offer can be generated or printed as DA84.

Price requests

Split the BoQ for subcontractors

With the BoQ filter and the Excel export you can split a GAEB BoQ. GAEB-Online 2023 offers enormous advantages for orders with different subcontractors. You can use the BoQ filter to filter the BoQ using the ordinal numbers, for example, and create Excel tables for the various subcontractors. Your subcontractors calculate in Excel or another office program such as OpenOffice and send the completed spreadsheets back to you. If necessary, you still enter surcharges and import the Excel file with GAEB-Online 2023 into the offer file. Save the offer as DA84 or print it out, done.


GAEB-Online 2023 searches for any terms in all short and/or long texts of a GAEB tender. This makes it possible to find specific items or articles quickly and easily, even in large tenders.

Conditional formatting

GAEB-Online 2023 supports conditional formatting. Actually this is a function known from the world of Excel or OpenOffice. With conditional formatting, the display of a cell in the BoQ can be made dependent on conditions or rules. If the content of the cell changes, the display changes automatically. With conditional formatting it is possible to color cells of a table according to certain criteria.

Conditional formatting

When calculating GAEB-BoQs, this offers the possibility to store special rules that mark the BoQ or positions by color or symbols. You can define a rule that marks all positions without a price in red. Or, for example, mark all prices with a symbol if greater than 10,000 euros. The special feature: You can save rules and use them in the next tender.

Conditional formatting

Search window

With the new search window it is now even easier to search in the BoQ table. It allows to find in a BoQ the positions that correspond to several search criteria. For example, you can search and display all the positions that contain both "wall" and "construction site".

New search window

Show Structure tree only

A new interface with a new BoQ structure tree offers the possibility to navigate quickly in the BoQ and shows all relevant information in the table. With just one mouse click, the interface can be switched so that only the table is visible for quick price entry.

Structure tree


When opening a GAEB tender, it is analyzed by GAEB-Online 2023 within seconds and the item types are displayed graphically in the BoQ statistics. This is an important advantage especially for extensive BoQs to get a first overview as an estimator. Here you can immediately see how high the proportion of possible alternatives or requirement items is, which can then be calculated "tactically" if necessary.

Statistics of a GAEB-File

Fast print preview.

GAEB-Online 2023 has a quick print preview. In the preview you can directly print, navigate and browse the GAEB BoQ or your offer or export the data to other formats. All file outputs can also be sent directly by e-mail. A special feature is the watermark function to mark the preview of a quote e.g. as "confidential" or as "draft" or "confidential".

Print preview

Design expression

With the integrated RTF BoQ editor, GAEB-Online 2023 offers a powerful tool to freely design the print output of a GAEB tender according to your wishes. Alternatively, you can export the complete GAEB BoQ to a word processor such as MS-Word, OpenOffice or LibreOffice.

Print Table of contents

If desired, GAEB-Online 2023 automatically adds a table of contents for the first two area groups to each GAEB tender during printout. This provides a better overview when printing and can be used for quick navigation in the page view.

Print Bidder details list

Many public contracting authorities require bidders' details in invitations to tender. These must also be attached to the offer with a so-called bidder information list. In a bidder details list, all items that receive bidder details are listed and printed out. If desired, GAEB-Online 2023 creates a bidder details list from the bidder details entered in the bid.

Output as PDF

From the print preview, GAEB-Online 2023 can save a quote as a PDF at the click of a mouse or send it immediately as a PDF by e-mail. Here you can, for example, assign a password protection for the PDF or, when using a digital signature, also digitally sign the PDF.

With GAEB-Online 2023 prices can also be imported from DA84 files of the formats GAEB 90 (*.D84), GAEB 2000 (*.P84) and GAEB DA XML (*.X84) into an opened GAEB-BoQ.

OpenOffice and OpenDocument

In addition to Microsoft Excel®, you can also use GAEB-Online 2023 to create your quotation calculation directly in the free office packages OpenOffice (Apache OpenOffice®) or LibreOffice®. GAEB-Online 2023 generates the *.ods format (OpenDocument table document) directly.

10,000 positions in few seconds.

If you export a GAEB tender to Microsoft Excel® or to an OpenDocument table document for e.g. OpenOffice, it takes only a few seconds. On a standard computer with Windows 10, exporting a GAEB BoQ with 10,000 positions takes only a few seconds.

Excel: Check during import

When importing prices from Excel or OpenOffice, the calculation file is now checked for possible errors and the corresponding error line (row / column) is displayed directly. This allows quick corrections and fluent work when calculating with Excel.
