Which plan to pickSimple works for a small team in one state. Move to Plus once you need time tracking, next-day pay or staff in more than one state, which is where most growing businesses land. There's no contract, so you can switch any time.Run the 7-day trial on contracts you actually negotiate, then ask for a quote. Get the per-seat price and any minimum term in writing, as third-party reports put prices anywhere from under US$200 to around US$350 per user a month.In the US, start on Growing unless you send fewer than 20 invoices a month. In Australia, pick the plan that covers the number of people on your payroll. New customers get a large discount for the first 3 months, so check the current offer before you buy.
