Nothing is free and you get what you pay for. If its simple recs then just use Excel. If its a lot of assets or volume of data look into either IT building in-house or buying. I would not expect a free tool to work if your process is very time consuming. We use Cadency and does a lot like workflow, automatic extraction from downstream systems, connection to GL, etc that we use for about 2500 reconciliations monthly. Depends on what you want to accomplish or make easier.
