I purchased the Pro1C version here, which cost almost 25 thousand. This is a one-time payment, with no monthly or yearly fees like most builders. I specifically needed this version for full integration with the 1C system. Now I can export and import products by catalogs, characteristics, and other parameters, track the status of warehouses and orders in real-time, as well as generate and export original invoices and bills with all necessary details (signatures and stamps in Word, Excel, HTML) and much more. The license comes included, so everything is official. We chose a different hosting provider that we have been working with for a long time and trust, as the disk space here is quite limited. The builder is fairly standard, the process is familiar, and there are many modules and blocks, so everything necessary for the full operation of a serious online store is available.
