Arithmetic you would otherwise do in a spreadsheet, with the assumptions shown so you can argue with them.

There are six calculators here, and each one answers a question you'd otherwise settle with a guess. What are unanswered calls costing you? Which billing model suits your phone? How much of the week is nobody picking up? The sums run in your browser as you type. There's no signup, and no email box standing between you and the answer.

One rule shaped all of them. Every number that describes your business comes from you. You won't find a built-in missed-call rate, a typical job value or an average receptionist wage, because we have no honest source for any of those. GreetKeeper is a new product with no customer data behind it, and we'd rather hand you an empty box than a statistic we can't defend. Each form opens with example numbers so you can see it work. They're labeled as examples, and they're there to be typed over.

The only fixed figures are our own plan prices, allowances and overage rates. Those are read straight from the pricing table, so a tool can never disagree with the pricing page. Where a tool compares us with another vendor, you enter that vendor's quote yourself. Prices move, and a stale figure inside a calculator does more harm than a blank.

Every page shows its formula in plain words and walks through one example by hand. Check the sums with a pencil if you like. You'll also find a short list of what the tool can't tell you, because a calculator that hides its limits is selling something. A missed call isn't always a lost job. A cheaper bill isn't always the better service.

Not sure where to begin? Match the tool to the question. The missed call cost calculator puts a dollar figure on the calls nobody answers. The answering service cost calculator sets a per-minute or flat quote beside per-call billing at your volume. The plan picker finds the lowest GreetKeeper bill for your call count. The receptionist comparison prices a hire against a service, on the wage you enter. The coverage planner adds up your closed hours. The volume estimator builds a monthly call count from one normal day. Start anywhere. Each page links to the next one you'll need.

A sensible order, if you're starting from nothing: estimate your call volume, plan your closed hours, then pick a plan. The cost comparisons make more sense once you trust the call count going into them.
