PARTNER BATTLECARD · SALESAI VS. SYNTHFLOW
THE RECOMMENDATION
Choose it when the client wants calls answered, leads contacted quickly, and compliant SMS follow-up without staffing a voice-agent build. Choose Synthflow instead for custom voice, complex transfers, white-label portals, or enterprise requirements. The feature index below is tied because it is unweighted; this is a fit recommendation, not a claim that SalesAi wins every feature.
01 / SPEED
Calls new leads within seconds of form or CRM activity.
02 / CONSENT
Opt-in, STOP, and Do Not Contact controls are built in.
03 / ENTRY
$249 per month plus usage, without a stated enterprise annual floor.

Sourced from public docs, changelog, and pricing as of September 16, 2026. Synthflow voice site docs.synthflow.ai and the official changelog where possible; third-party reviews are marked. Internal use — do not forward to prospects without removing the ‘lose’ column.
Feature-by-feature
Compare documented voice, messaging, platform, and partner-economics capabilities. A toss-up is a genuine trade rather than a forced winner.
How the scoring works
This is a verdict-based comparison index, not an independent performance test. Across 24 rows, a win earns 2 points, a loss 0, and a toss-up 1 for each product. SalesAi and Synthflow each total 24/48, with 8 wins apiece and 8 toss-ups. The unweighted index does not measure which product best fits a particular agency.
The 24–24 index is an unweighted tally, not the buying decision. SalesAi’s documented edge for this audience is immediate lead response, built-in texting consent, a ready-to-use agent, and a $249 monthly entry price plus usage. Synthflow wins other rows for advanced building and enterprise needs. Do not pitch SalesAi as the cheapest at every usage level; compare actual quotes at the client’s expected volume.
Inbound call handling
TOSS-UP
SalesAi 1 · Synthflow 1
Inbound agents answer, qualify, book, and route calls around the clock. Prompt and script-based flows.
Inbound agents built in Flow Designer with subflows as specialized agents; business hours per agent and specialized call intents.
Both cover inbound calls.
Speed-to-lead outbound calling
SALESAI
SalesAi 2 · Synthflow 0
Dials new leads within seconds of CRM entry or form submit; Double Call auto-redial; outbound number assigned per agent.
Outbound via API-triggered calls and campaigns via API; number pooling, voicemail drop, IVR/DTMF navigation, and no-input fallback.
SalesAi wins for immediate lead response: it calls within seconds of a form or CRM event. Synthflow offers richer API-driven outbound campaigns, number pooling, and IVR controls; this verdict is about speed-to-lead, not outbound breadth.
Live transfer to a human
SYNTHFLOW
SalesAi 0 · Synthflow 2
Warm transfer passes conversation, context, and intent; Live Transfer and Number Directory CTAs; secondary CTA.
Cold, Warm-with-Message, and Warm-with-Summary transfer; human detection to avoid voicemail; blind, warm, and cold transfer logic.

TOSS-UP
SalesAi 1 · Synthflow 1

In-call SMS and WhatsApp, post-call SMS on trigger, and cross-channel memory across voice, SMS, and WhatsApp.
Both connect voice and messaging.

Finished agent vs. builder
SALESAI
SalesAi 2 · Synthflow 0
A ready-to-use agent with best-practice starting flows and an outbound speed-to-lead workflow; sold at $249 per month plus usage.
A no-code builder, not a receptionist; estimate of 8–20 operator hours to a production agent, plus ongoing tuning.
Less agency build work.
SMB purchase path
SALESAI
SalesAi 2 · Synthflow 0
$249 per month plus voice-minute and SMS usage gives an SMB agency a stated starting price. It does not include a claim of dedicated management or custom setup.
Synthflow is a self-serve builder, but its public pricing shifted toward enterprise; reported enterprise contracts start at $30,000 annually. Verify any agency-specific offer.
SalesAi has the clearer documented monthly SMB starting point. This is an access verdict, not a promise of additional services.
Support model
TOSS-UP
SalesAi 1 · Synthflow 1
Confirm the current support channels and response commitments for the $249 monthly plan. Do not promise dedicated management, scheduled strategy calls, or optimization services as part of this price.
Ticket-based; Slack access limited to first 30 days; reported post-customer responsiveness is a pain point.
Support commitments need confirmation for both offers. Do not infer a dedicated service tier from the $249 monthly price.
Partner margin model
TOSS-UP
SalesAi 1 · Synthflow 1
The current offer is $249 per month plus voice-minute and SMS usage. Do not assume a referral commission, wholesale schedule, or reseller margin without current partner terms.
Agency owns rebilling through Stripe; margins are markup over per-minute cost plus BYOK fees. No referral commission structure documented.
SalesAi partner margin is not established by the $249 monthly offer alone. Confirm current resale terms before comparing agency earnings.
Security & compliance certifications
SYNTHFLOW
SalesAi 0 · Synthflow 2
SOC 2 badge on site; SMS consent and audit trail enforced.
SOC 2, HIPAA, PCI DSS, GDPR, ISO 27001, PII redaction, 2FA, MSA/DPA, and 99.99% uptime SLA claim.
Broader published certifications.
White-label & multi-client packaging
SYNTHFLOW
SalesAi 0 · Synthflow 2
$249 per month plus voice-minute and SMS usage. Confirm number, client-account, and branding limits in the current plan; no white-label portal is claimed here.
Unlimited sub-accounts, branded client portal on custom domain, per-subaccount minute allocation, Stripe rebilling and agency/white-label tools.
More agency packaging tools.
Price predictability
SALESAI
SalesAi 2 · Synthflow 0
$249 per month plus usage for voice minutes and SMS. The fixed monthly charge is clear; total spend still varies with usage.
Pure pay-as-you-go: quoted from $0.08–0.09/min; effective rates vary with LLM, telephony, and add-ons.
Simpler base commitment.
Usage pricing
TOSS-UP
SalesAi 1 · Synthflow 1
$249 per month plus metered voice-minute and SMS usage. Current per-unit rates and included amounts should be confirmed before a cost comparison.
About $0.15–0.24/min effective; volume rates to $0.07/min at enterprise scale. Only successful minutes billed.
No universal per-minute price winner can be established from the stated SalesAi offer and the available Synthflow estimates. Quote both at the same expected monthly volume.
Home-services fit
SALESAI
SalesAi 2 · Synthflow 0
Positioned on capture leads, chase quotes, book jobs; FSM integrations and trade-specific roleplay demo.
Native ServiceTitan, Housecall Pro, and Jobber, but positioned at BPQ, healthcare, fintech, and telecom; no public contractor case studies.
Purpose-built contractor pitch.
SMB entry point
SALESAI
SalesAi 2 · Synthflow 0
$249 per month plus voice-minute and SMS usage. No enterprise annual commitment is stated for this offer.
Fixed monthly tiers ($29–$899) retired in 2026; no free tier; enterprise contracts start at $30,000/year. SMB support degrades to tickets after 30 days.
Clear SMB entry.
Pricing side by side
Synthflow’s public pricing changed shape in 2026 — its official page now shows only an enterprise floor. The per-minute figures below are third-party and should be treated as ranges.
SalesAi pricing
$249 per month plus usage for voice minutes and SMS. Total monthly spend depends on usage. Confirm current rates, included limits, and any account or number terms before quoting.
Synthflow pricing
Pay-as-you-go, no subscription — quoted starting around $0.08–0.09/min, with effective rates around $0.15–0.24/min after model, telephony, and add-ons. Enterprise contracts start at $30,000 annually; agency and white-label pricing is reported separately. Verify current rates before quoting.
What a partner hears, and what to say back
Honest answers. If the objection is true, say so and move to the ground we hold.
“Synthflow has 200 integrations and native ServiceTitan, Housecall Pro, and Jobber. You have a webhook.”
True on count. Ask which three the client actually uses. If they’re on a supported FSM, we connect natively too; if not, a post-call webhook pushes outcome, transcript, and contact to what matters. CRM choice is not the buying decision — a running agent is.
“Their transfers are better — whisper, AI summary, SIP, dynamic routing.”
They are. If the client runs a PBX, on-call rotations, or a contact center, Synthflow’s transfer stack is the right tool. For a two-truck HVAC shop, warm transfer with context to the owner’s cell is the whole requirement, and we do that out of the box.
“It’s pay-as-you-go with no platform fee. Why pay $249 a number?”
Synthflow’s pay-as-you-go model may cost less at low volume; we cannot claim a universal price win. SalesAi has a clear $249 monthly charge plus voice-minute and SMS usage. Compare total spend at the client’s expected volume, then weigh the build and operating effort separately. Do not imply setup services are included.
“I want to white-label. Synthflow gives me a branded portal, sub-accounts, and Stripe rebilling.”
We don’t have a branded portal in this comparison. Synthflow’s agency plan is built for white-label rebilling. SalesAi’s stated offer is $249 per month plus usage; confirm branding and resale terms before promising an agency margin or client portal. If owning the branded portal is essential, Synthflow has the stronger documented fit.
“Synthflow is SOC 2, HIPAA, PCI, ISO 27001. What are you?”
SOC 2, and we enforce SMS consent at the platform level. For healthcare or payments, Synthflow’s certification list wins and we should say so. For home services, the compliance that bites is TCPA on texting — the mandatory consent opener, STOP/DNC handling, and audit trail are ours by default; on Synthflow the operator builds them.
“My team can build and test agents faster on their Flow Designer, and roll back if it breaks.”
Their tooling is better for teams that want to be builders. Test Center, simulations, versioning with rollback, and Auto-QA are advantages we should acknowledge. The comparison for an SMB agency is whether it wants to own that build-and-tune work or start with SalesAi’s $249 monthly agent plus usage.
“They pivoted to enterprise. Does that matter to me?”
It matters if your clients are small. Fixed tiers were retired, enterprise starts at $30K a year, and support goes ticket-only after 30 days. An agency reselling to $1–5M contractors is now Synthflow’s least-served segment, and SalesAi’s Core one.
