Frequently asked
- What is a flat-rate AI answering service?
- A flat-rate service charges one fixed monthly fee with no per-minute or per-call usage charges inside the plan. Your bill is the same whether you take 10 calls or 1,000, which makes budgeting predictable but can be wasteful at very low volume.
- Is flat-rate cheaper than pay-as-you-go?
- It depends on volume. Pay-as-you-go (per-minute or per-call) is cheaper at low call counts; a flat plan becomes cheaper once usage is high enough that metered billing would exceed the flat fee. Fixing a workload is the only way to compare them honestly.
- Do flat plans have hidden overage?
- Some flat plans cap usage (included minutes, calls, or unique customers) and bill overage beyond it. We record the published overage rate where a vendor states one and flag plans where the overage rate is not published rather than estimate it.
