An invoicing tool?
 

I recently transitioned from a management position in the operations department to starting my own independent consulting firm. During my years in the corporate world, I never had to think about the mechanics of invoicing—it was all handled by a specialized accounting department using enterprise-grade software.
Now that I'm running my own bookkeeping, I've realized that while I need professional results to maintain my brand's reputation, I'm not yet at the point where a monthly subscription to a full suite of services is justified. Now I'm looking for that sweet spot: a tool that's functionally robust yet cost-effective.
