I too have hit this ridiculous limit. Hired nearly $50k worth of talent over two businesses in the last couple of years now upwork wants to charge me extra to invite more than three freelancers? In addition, they have taken away all the reporting etc unless you pay a fee each month. It's getting ridiculous.
As part of the Basic plan you have access to several reports:
-Transaction report. This gives you a detailed view of all your Upwork transactions. Please, hover your mouse over Reports tab and then click Transactions to access it.
-Freelancer work diaries. Visit the Contract Room for any project to see a freelancer’s Work Diary.
-Weekly Summary email. Account admins will get this weekly email report, which includes details such as the hours logged by your freelancer(s).
Based on data about how clients use reports, we expect that the tools above will give the majority of clients the information they need to manage their projects. However, in cases where clients need more information, we are offering the paid Client Plus plan.
