I am working for a commercial landscaping company. We have many contracts and the month to month work taking place varies greatly for each customer. Some of the contracts are pay per service and our revenue entries match up with our cost. The majority of our work is paid in monthly increments or lump sums that do not align with our costs. The monthly close process should consist of entries to adjust earned or deferred income/revenue for our regions. I realize the proper method is almost doing what construction companies do which is a WIP and utilize quantities on each project to develop a true earned revenue adjustment number. The problem is, we have so many small projects and they constantly vary I would be tying up so many valuable people for days on end to get this monthly number remotely close. We are using quick books and currently researching a replacement. Any recommendations here would be great as well. What would be the best way to estimate our correct revenue each month?
