Work in progress is work that you have done for your clients but haven’t billed yet. Work in progress is indicated on activity slips by a value other than zero in the Left to Bill field.

Your accounting records will only reflect a sales transaction when you bill the activities. However, some accountants consider that, from an accounting perspective, your clients owe you for your work in progress even if you haven’t yet billed your clients for it.

If your work in progress routinely represents a significant amount of money, you should consider adjusting your accounting records to reflect this. Consult your accountant for advice on how to do this.
