Switch from SRFax to DDSFAX

Why dental practices leave SRFax

SRFax is a Canadian-headquartered cloud fax product with a focus on regulated transmission. The Healthcare tier prices in the $151 to $193 a year range depending on the page cap, and the regulated contract language is included on every Healthcare plan, which means the contractual scope is right for a dental practice. The trouble is the structural one: the page caps are aggressive, the overage rate is among the higher in the category, and the platform charges a $25 port-out fee that, while small, signals where the product priorities sit.

Walk through the cap. SRFax Healthcare's entry tier is 200 pages a month. That is not enough for any dental practice with a regular insurance verification workflow — 200 pages is roughly two weeks of normal sending. The next tier up adds capacity to 500 pages, which is closer to dental reality but still under the realistic monthly volume for most practices. Above the cap, overage runs $0.04 per page, which compounds quickly. A practice that runs 600 pages a month on the 500-cap plan pays the base $193 plus $48 in overage across the year — a real cost of $241, before counting any of the higher-volume months.

DDSFAX is $189 flat for unlimited pages. There is no overage band, no soft cap, no cap-tier upgrade path. The price is the same whether the practice runs 100 pages a month or 5,000. For a typical dental volume in the 350 to 800 page range, DDSFAX is straightforwardly cheaper than SRFax Healthcare's realistic all-in cost, and the savings widen as volume grows.

The $25 port-out fee on SRFax is small in absolute terms, but it points to a product philosophy where leaving costs something. DDSFAX charges $0 to port out, ever. Your number is yours. That commitment matters less in any given migration moment and matters more across the multi-year horizon — there is never a friction point that makes a future switch awkward.

The other consideration is geographic routing. SRFax is a Canadian platform that routes some traffic through Canadian infrastructure, which can introduce subtle latency or delivery quirks for U.S.-based dental practices, particularly when the receiving fax endpoint is on a legacy T.38 gateway. DDSFAX runs U.S.-domestic infrastructure with redundant carrier paths, which produces a lower observed failure rate on the long tail of receiving endpoints — the obscure analog fax machines at older specialist offices that still see meaningful U.S. dental traffic.

Product surface is generalist vs. dental. SRFax's dashboard supports any regulated workflow — dental, medical-adjacent, legal — and the directory and tagging are unstructured. DDSFAX organizes around dental from the start: payer directories, lab directories, referring practice directories, and the inbound log is pre-tagged for prior authorizations, claims correspondence, and referrals. The hours of setup work that SRFax requires to make the directory match a dental shape are not necessary on DDSFAX.

Migration is clean despite the $25 port-out fee. SRFax releases numbers in three to five business days. The DDSFAX migration team files the LOA, schedules the carrier handoff, and handles the small port-out cost as part of the kickoff if the practice prefers a single-line cutover with no SRFax interaction. Most practices choose to absorb the $25 themselves to keep the migration simple.

The breakeven against SRFax depends heavily on the cap tier and the monthly volume. A practice on the 200-cap plan running 400 pages a month is paying $151 base plus realistic $96 overage = $247 a year on SRFax, vs. $189 on DDSFAX — a $58 savings. A practice on the 500-cap plan running 700 pages a month is paying $193 base plus $96 overage = $289 a year, vs. $189 — a $100 savings. In both cases, DDSFAX is cheaper, more predictable, and dental-shaped.
