What are the most important features in a restaurant point of sale system?

The digital tab is the most powerful feature a restaurant point of sale system can offer. Digital tabs allow restaurant operators to give their guests complete control over their ordering and payment experience. And because the digital tab travels with the guest, guests get to order what they want, when and where they want it. Two-way text communication is also an important feature as it allows the quickest way to clarify ordering questions and ensure the guest knows what to expect in terms of fulfillment time.
