Pricing calculator to write to scheduler to QBO

Looking to convert an excel pricing calculator into a tool that will write to allow event scheduling (under development in SQL, but also need a temp solution) and output to Quickbooks online for revenue recognition. Example, sales agent prices 10 events, need to capture this as 10 rows with name, program, price, client detail, deal number etc. this would need to plug into SQLserver once ready, but until then it needs to allow to plug in dates for each event. The dates and $ would drive revenue recognition. It would be nice if it could output into QuickBooks online via API. Looking for time and cost quotes and type of solution. Calculator interface and logic with writing into a database, temp scheduling solution form, output into Quickbooks online of price times quantity based on scheduled date. Ability to pull data for planning.
