Door-to-door subscriber acquisition for rural and small fiber ISPs

A contracted door-to-door crew adds subscribers to a rural fiber network the way it does in a subdivision: reps knock the homes the network passes, sign orders on the porch, and the ISP pays a fixed fee per activated subscriber. The rural difference is one input, homes per road mile, which sets doors per rep-day and therefore cost per activation; this page shows that math at 5, 10, and 20 homes per mile, the NRTC benchmarks, and the minimum market size for a crew.

Doors per rep-day at 5, 10, and 20 homes per road mile

The formula: doors per rep-day = knock hours × 60 ÷ (minutes at the door + minutes between doors). Cost per activation = cost of a rep-day ÷ activations per rep-day. Every input below is an illustrative assumption labeled [estimate]. The rep-day cost stays as C; the output that matters is the multiplier between densities.

• Knock hours per rep-day: 6 [estimate].
• Minutes at the door, averaged over answers and no-answers: 5 [estimate].
• Minutes between doors: 1 at 20 homes per mile, 2.5 at 10, 5 at 5 [estimate]. Spacing is 5,280 feet per road mile divided by homes per mile; at 5 per mile that is 1,056 feet, then a driveway or a gate.
• Funnel, held constant across densities: 40% of doors answer, 10% of answers order, 85% of orders activate [estimate].

A territory at 5 homes per mile costs the crew about 1.7 times as much per activation as one at 20, so a vendor quoting one rate for both has mispriced one of them; ask how the rate was built. Minutes between doors moves the number most, which is why rural crews route by road segment and knock every home on a road in one pass [field experience].

The rural benchmarks to plan against

NRTC's 2024 Rural Broadband Operations Benchmarking Report (84 respondents, 33 states, relayed by Telecompetitor) is the one public rural benchmark we have found that reports acquisition cost, ARPU, and churn together: customer acquisition cost $135, ARPU $74 a month, churn 0.9%, lifetime value just over $5,000, and 64% facing a competitor at 100/20 Mbps or better. The relay does not say what the $135 includes; read it as a floor for an established local operator [inference]. At $74 ARPU, each $100 of acquisition cost takes about 1.4 months of revenue to recover; fiber subscriber acquisition cost by channel covers payback by channel.

RVA's 2024 to 2028 forecast put fiber past about 42% of small-town and rural homes against 55% in cities and suburbs, with about 22 million rural homes unpassed at RVA's early-2024 count (Telecompetitor). The national average take rate is 46.5% on unique passings (Fiber Broadband Association, April 2026); a rural build well below that a year after lighting has room a mailer will not close [inference].

Greenfield markets with no cable competitor

Where the alternative is DSL, fixed wireless, or satellite, the porch conversation is an upgrade, and NRTC's 53% band is the ceiling to aim at [inference]. Drop length changes the rep's job: an average buried drop under 100 feet cost $556 and one over 500 feet $675 (Cartesian 2025 survey via CCG Consulting), so the rep confirms drop route and install window on the porch; an order that cancels before install is a chargeback the vendor eats. In a build that lights one fiber serving area at a time, the crew knocks each area as it releases.

Copper-telco footprints being upgraded to fiber

Two rural copper footprints, 20 states and 18 states, are mid-upgrade. Brightspeed, which bought Lumen's ILEC operations in 20 Midwest and Southeast states in a sale that closed 2022-10-03 (Telecompetitor), describes its footprint as rural and suburban communities across 20 states (Brightspeed). Kinetic by Windstream serves 18 states, had passed 2 million fiber premises by mid 2026 (Kinetic), and lists door-to-door sales as a dealer program option in its $2 billion build (Kinetic dealer page).

For a small ISP whose footprint overlaps one of these, the planning number is NRTC's 33%: every home activated while the incumbent is still on copper is a home its fiber launch has to win back [inference]. A crew can knock every home in one fiber serving area before the incumbent lights fiber there.

Minimum viable market size for a crew

A crew of 4 reps, 5 days a week, 3 weeks: 60 rep-days. At 36 to 60 doors per rep-day that is 2,160 to 3,600 door attempts, enough for a first pass and a return to no-answers across roughly 1,100 to 1,800 homes passed [estimate]. Below about 1,000 homes passed, the fixed cost of moving a crew in (travel, lodging, permits, onboarding) spreads over too few activations [estimate]. Knoqly's one published deployment was a 1,317-address market: penetration went from 2.43% to 19.74% in 14 days, 228 new subscribers [Knoqly deployment data]. Smaller footprints work when adjacent towns are batched into one route or each fiber serving area is knocked in the week it lights [field experience].

Travel crews, lodging, and permits across county lines

Reps travel in and are housed near the territory for the run. Driving scales with density: in a 5-homes-per-mile territory a rep covers 40 to 80 miles a day including the drive from lodging [estimate], which at the IRS business rate of 76 cents per mile (July 1 to December 31, 2026, IRS) is $30 to $61 per rep-day before lodging. These costs sit inside the vendor's per-activation rate, so a rural rate reads higher than a suburban one, and crews are scheduled in blocks of consecutive days.

Permits follow jurisdiction lines, and a rural market crosses several. The county, the towns inside it, and each city can issue its own peddler or solicitor permit, with its own fee, hours, and badge requirement. Knoqly looks up each jurisdiction's solicitation rules before the crew knocks and agrees with you who files where a permit is required; ask for the permit process, per jurisdiction, in writing before the crew arrives. Who handles permits, CPNI, and badges when sales are outsourced covers the split of duties.

How to get more subscribers for your ISP: the sequence

1. Pull penetration by fiber serving area. Areas lit 6 months or more and under 30% penetration are the crew's first list [estimate].
2. Send mail and run local digital 2 to 3 weeks ahead so the knock is expected [field experience]. Those channels land between $150 and $300 per subscriber [field experience].
3. Confirm install capacity before the crew arrives. Orders sold into a backlog cancel, and every cancel inside the window is a chargeback.
4. Contract per activated subscriber with a chargeback window, billed from your own install report so you pay only for accounts that activated.

The fiber take rate calculator takes serviceable addresses, current penetration, revenue per subscriber, terminal take rate, crew size, and cost per subscriber for door-to-door and for your other channels, then charts four years of penetration, revenue, and cumulative acquisition spend for both paths side by side. What a contracted crew does and costs covers the engagement; a discovery call covers your territory.
