Full sales development output. No full-time hire. No ramp. No seat to fill when it doesn't work out.
A fractional SDR is a sales development function you access at a fraction of the cost and commitment of a full-time hire. Same output — prospecting, outreach, qualification, calendar delivery — without the salary, benefits, management overhead, and 90-day ramp that come with bringing someone in-house.
The term gets used loosely. Some vendors use "fractional SDR" to mean a part-time contractor who sends emails. Others mean a shared-resource pool spread across multiple clients. Neither model works well for marketing agencies, because neither can deliver white-label output — the non-negotiable requirement when your client thinks the meetings are coming from you.
FlowCraftPro's fractional SDR model is built differently. It runs as a fully managed, fully branded outbound function — dedicated infrastructure, vertical-specific sequences, BANT qualification on every reply — delivered under your agency's name. Your client never sees a third-party vendor. You get the meetings, the margin, and the credit.
The math kills the full-time SDR argument fast.
A full-time SDR costs $50k–$80k loaded — plus tools, management, and 60–90 days of ramp before the first consistent booking
Agencies that treat sales development outsourcing as a productized function — rather than a hiring decision — cut that timeline to 14 days and eliminate the fixed cost entirely.
Fractional eliminates every line item except results: no salary, no tools budget, no onboarding
Because it's productized, fractional SDR packages cleanly as a retainer add-on with 2–3x markup and no delivery risk
The first-5-meetings guarantee passes through to your client — the risk sits with us, not with you
Three phases across 90 days — infrastructure, launch, and optimization.
The full function — not a part-time email sender.
Domains, warmup, DKIM/SPF/DMARC, inbox rotation — under your brand, not ours. The layer most vendors skip and the reason most outbound burns out after three months.
Pre-built sequence libraries for HVAC, plumbing, roofing, solar, med spa, dental, legal, accounting, and IT outsourcing. Nine verticals, each with its own pain hooks and ICP criteria baked in.
Prospect-level research at scale. The AI agent crawls each prospect's site, pulls a vertical-specific signal, and writes a first line that reads as hand-researched. Not a token swap. Not mail-merge.
Every reply reviewed and routed. Meetings only go to your calendar after Budget, Authority, Need, and Timing are confirmed. Prospects who clear three of four enter a nurture sequence.
Branded invites from your domain. Confirmation and reminder sequences. Automated rescheduling — 60% of no-shows recover with one follow-up.
Every client-facing touchpoint carries your brand. Calendar invite, confirmation email, reminder, reporting — all yours. FlowCraftPro is never visible.
The terms get used interchangeably. For practical purposes, the distinction comes down to scope and framing.
| Fractional SDR | Outsourced SDR | |
|---|---|---|
| Framing | Partial sales development function | Full SDR function, external |
| Best for | Agencies testing outbound or adding it as a client service | Agencies replacing or augmenting an existing SDR motion |
| Commitment | 90-day minimum | 90-day minimum |
| Output | Qualified meetings on calendar | Qualified meetings on calendar |
| White-label | Yes | Yes |
| Guarantee | First 5 meetings free | First 5 meetings free |
