Online fax pricing pages are masterworks of selective disclosure. The $9.95 is in 48-point type; the conditions that turn it into $19.40 are distributed across a footnote, a checkout screen, and a support article. Having audited every provider in our database, here are the six fees that actually appear on bills — and the question that defuses each.
1. The setup fee
eFax charges a $10 one-time setup fee on monthly billing and quietly drops it on annual plans. Others waive it during promotions and reinstate it later. It’s pure margin — there is no “setup.”
Ask: “Is there any one-time fee at signup, and is it waived on annual billing?“
2. The overage rate
Covered at length in our pricing breakdown, but worth repeating as a fee: the per-page rate past your allowance ranges from 3¢ (Nextiva, MetroFax) to a punishing 20¢ (CocoFax Lite) across mainstream providers. On a plan whose allowance you regularly exceed by 100 pages, that spread is up to $204/year — far more than the subscription price difference between providers.
Ask: “What’s the per-page rate after my allowance, and does the counter reset monthly?“
3. The monthly-billing premium
Annual billing runs 15–40% cheaper. Framed the other way: monthly billing is an 18–65% surcharge for flexibility you probably don’t need after the first month. CocoFax has the widest gap we track — its Lite plan doubles from $4.99 to $9.99 when billed monthly, and Fax.Plus effectively hands annual subscribers three free months.
Ask: yourself, honestly — “Will I still be faxing in six months?” If yes, annual.
4. The toll-free and vanity number surcharge
A local number is included in every plan we track. Toll-free numbers often cost $5–10/month extra, vanity numbers more. Unless your customers specifically expect an 800 number, this is decoration.
Ask: “What number types are included at the plan price?“
5. The porting fee
Moving your existing fax number in (or out) can carry a one-time fee — and the “out” direction is the one to care about, because it’s your exit cost. Most major providers port in free; fewer commit in writing to free port-out.
Ask: “What does it cost to port my number in — and out, if I leave?“
6. The legacy-plan tax
The sneakiest fee isn’t a line item. Providers launch better plans for new customers and leave existing subscribers on old pricing indefinitely. We’ve seen readers on $16.95 plans whose current-catalog equivalent is $9.95. Nothing in the product reminds you to check.
Ask: your own invoice, once a year. Compare it against the provider’s current pricing page, and against our live comparison. Re-shopping a commodity subscription every year or two is the single highest-ROI five minutes in this entire product category.
The clean-bill checklist
Before subscribing anywhere, you want written answers (screenshot the checkout page — it counts) to:
- Total at checkout today, including any setup fee
- Monthly price after any promo period ends
- Included pages, pooled or split, and the overage rate
- Number type included; toll-free surcharge if any
- Port-in and port-out costs
- Cancellation terms on the billing cycle you chose
Every provider in our comparison has these numbers in its data profile — that’s the point of the site. The fax industry counts on you not doing arithmetic. Disappoint it.
