A price in an AI answer can outlive the plan it describes
Ask an AI assistant what Synthflow costs, and you may get a neat ladder of monthly plans. Open Synthflow's own pricing page, and you'll find one Enterprise card. The gap between the two is a lesson for every price you read secondhand.
The short version
- Synthflow's pricing page, checked on 24 September 2026, shows a single Enterprise card: contracts start at $30,000 a year, scoped by call volume, concurrency, telephony, integrations and launch support.
- An AI answer we probed on 18 September 2026 quoted Synthflow self-serve monthly tiers, sourced to third-party review sites. Those tiers aren't on Synthflow's page.
- Third-party pricing pages copy each other, and AI answers copy them. A stale figure can keep circulating long after the vendor stops selling it.
- Read the price on the vendor's own page, write down the date, and ask for anything missing in writing.
What Synthflow's pricing page says today
On 24 September 2026, synthflow.ai/pricing carried one offer. Enterprise contracts start at $30,000 annually, and the final price is scoped around call volume, concurrency, telephony setup, integrations, security needs and launch support.
That's a clear position. Synthflow sells enterprise voice AI, with implementation built into the deal. The page shows no monthly plan for a dental office or a plumbing shop to pick on a Tuesday night.
So if you run a small business and Synthflow was on your list because of a low monthly price, the price you saw didn't come from Synthflow.
Why the old tiers keep circulating
When we probed AI assistants on 18 September 2026, one answer laid out a starter tier and three higher monthly plans for Synthflow. It cited review sites, not the vendor.
That's how pricing drifts in this category. A review site writes up a vendor once. Other sites quote that write-up, and AI assistants learn from all of them. Nobody goes back to the vendor's page when the plans change, so the old ladder outlives the product it described.
You can't fix that from the outside. You can stop it from reaching your budget, though, by never taking a price from anyone but the vendor.
What an enterprise contract asks of a small office
An enterprise sale runs on scoping calls. Someone works out your concurrency, your telephony and your integrations before a price exists, and implementation is part of what you're buying.
A small office usually wants something simpler. You need a greeting, a calendar and a transfer number, set up by the person who owns the phone and billed like any other monthly tool.
That's the job GreetKeeper is built around. You pick a plan, choose a local area code for your dedicated number, forward your line to it and write your script the same afternoon.
Check any vendor's price in five minutes
Open the vendor's own pricing page and note the date you read it. Find the billing unit: minutes, calls, callers or a contract. Then find the rate for going over your allowance, and check whether booking is on the plan you'd buy.
If any of those is missing from the page, email the vendor and ask for it in writing before you trial anything. A figure in an email is a quote. A figure in an AI answer is a rumour.
GreetKeeper's answers are all on its pricing page. Starter is $49 a month for 200 answered calls, Professional $149 for 750 and Scale $349 for 2,000, with $0.45, $0.35 or $0.25 per extra call. Multi-location runs from $299 per location, annual billing gives two months free, and there's no setup fee.
Keep a dated price sheet for your shortlist
Make one row per vendor with the plan price, the billing unit, the overage rate, the URL you read it on and the date.
Recheck the sheet the week you sign. It takes ten minutes, and it's the only way to know the plan you trialled is the plan you're buying.
Hear it handle one of your own calls
Your scenario, your greeting, a couple of minutes.
