Sip-and-Puff Assistive Device Sales Core Five Startup Costs
Inventory and Demo Products Startup Expense
Inventory Buy Plan
Year 1 needs 8,300 units: 1,200 premium controllers, 2,000 mobile controllers, 800 mounting arms, 4,000 filter kits, and 300 sensor modules. Modeled revenue is $7.725M; direct unit cost is $1.009M, or about 13.1% of sales. That does not include tubing, connectors, packaging, or MOQ spillover.
Build the Buy List
This line covers resale stock, long-term demo kits, accessories, hygienic tubing, filter kits, switches, mounts, connectors, sensor modules, spare parts, and packaging. Price it from vendor quotes and minimum order quantities, then split inventory from demo CAPEX. One clean rule: resale units hit inventory; demo kits sit on the asset side.
Quote each SKU at MOQ.
Track demo kits separately.
Order spares by usage.
Control the Spend
Keep the first buy tight. Order only what covers launch demand, demo rooms, and repair risk, then replenish from actual pull-through. That avoids cash sitting in slow parts. The mistake to avoid is mixing resale stock with demo hardware, because it distorts gross margin and working capital.
Buy fast movers first.
Delay slow spares.
Use one demo kit per site.
Separate Demo CAPEX
Put long-life demo kits in CAPEX, not inventory, because they support sales over multiple cycles. Resale units are working stock and should stay on the balance sheet as inventory. Here’s the quick math: buying the wrong bucket skews cash need, margin reporting, and reorder decisions before Month 1.
Compliance and Professional Services Startup Expense
Compliance setup
Start here: this expense covers business formation, resale permits, supplier agreements, privacy and accessibility policies, product documentation, accounting setup, legal review, and quality procedures. If you pursue Medicare billing, add DMEPOS accreditation. The checklist changes with state rules, payer strategy, and sales channel, so don’t assume every item applies on day one.
Monthly run rate
Here’s the quick math: plan $3,500 monthly for legal and patent fees, $2,200 for administrative and software licenses, and $1,800 for cloud and health-data storage. That is $7,500 a month, or $90,000 a year, before compliance audits or filing surprises.
Separate setup from monthly support
Add audit costs if required
Keep channel-specific fees visible
Keep it lean
Use templates for formation papers, policies, and SOPs, then pay for review instead of full drafting. Ask vendors for fixed-fee scopes and separate one-time setup from monthly support. Do not cut privacy, accessibility, or quality work just to save a few hundred dollars.
Use templates first
Negotiate fixed legal scopes
Update docs by channel
Billing path risk
If you plan Medicare billing, budget extra for DMEPOS accreditation and related audit work. If you sell direct or through rehab partners, the checklist can be lighter, but state rules and sales channel use still change the work. The right budget follows the route you choose.
Website, Ordering, CRM, and Support Systems Startup Expense
Launch stack cost
This expense splits into one-time setup for the website and workflow build, plus monthly software from Month 1. For this device business, the stack must handle product pages, secure intake forms, quote workflow, order processing, customer relationship management, inventory tracking, helpdesk, video support, and remote setup.
One-time build
The setup quote should cover an accessible site, product pages, secure forms, quote routing, order processing, and support tools. Get fixed bids for page count, form count, integrations, and training. Use separate line items for design, build, testing, and launch so the startup budget does not bury software in the one-time cost.
Monthly run rate
Model recurring cost at $2,200 per month for administrative and software licenses, plus $1,800 per month for cloud and health-data storage from Month 1. That is a $4,000 monthly base before payment fees, which are not provided and should stay out of the model until a processor quote is signed.
Data risk controls
This stack handles intake, support, and health-related data, so use secure forms, role-based access, backups, and logged changes from day one. The main risk is broad access to customer records. Keep storage and support tools scoped to what staff need, and tie the setup to the same rules used for every order and remote session.
Insurance, Warranty, and Returns Readiness Startup Expense
Readiness Costs
For a launch like this, insurance and returns readiness sit in pre-opening expense and working capital, not CAPEX. Plan for product liability, general liability, cyber coverage for customer data, and workers’ compensation if you hire. The known anchor is $4,200 per month for product liability insurance.
What To Fund
Budget returns support with warranty reserve, return shipping, replacement handling, and RMA processing. Here’s the quick math: use 35% of Year 1 shipping/logistics cost as a planning input, then layer replacement exposure from direct unit costs of $392 premium controllers, $195 mobile controllers, $60 mounting arms, $11 filter kits, and $188 sensor modules.
Use unit mix, not guesswork.
Keep reserves off CAPEX.
Update after carrier quotes.
Keep It Tight
Reduce waste by separating normal resale inventory from demo kits, then track each return by reason code. Don’t set claim rates without data. Price the reserve from carrier quotes, shipment volume, and expected replacement mix, and review it monthly once orders and support tickets start coming in.
Quote insurance before launch.
Track RMAs by product type.
Hold cash for returns.
Reserve Setup
Classify premiums and warranty funds as launch cash needs, not assets. If hiring starts early, add workers’ compensation before first payroll, and make sure cyber coverage matches how you store customer data. The real control is simple: fund the exposure up front so replacements, returns, and support don’t hit operating cash later.
Office, Fulfillment, Staffing, and Launch Marketing Startup Expense
Facility Setup
Workspace deposits, an ISO-capable facility or compliant storage, shelving, packing stations, shipping supplies, and customer support setup should sit in fixed assets and deposits, while launch stock stays in working capital. With a $12,500 monthly lease, the cash need depends on how many months of occupancy, fit-out, and first shipments you fund.
Training and Wages
Pre-opening staff and vendor training belongs outside the startup lump sum. Keep the model’s $37,700 fixed overhead before wages separate, and if the CEO is paid from Month 1, add $185,000 a year, or about $15,417 a month. That split keeps labor visible before sales ramp.
Train before first orders.
Track wages separately.
Use month-one cash only.
Launch Outreach
Marketing should fund accessibility-focused content, referral outreach, and calls on rehab clinics, ALS organizations, spinal cord injury groups, and assistive technology professionals. Budget $8,000 a month for marketing and trade shows, and treat it as working capital, because these channels pay back through demos, referrals, and installs, not instant volume.
Cash Map
Do not fold everything into one startup line. Split fixed assets, deposits, pre-opening training, and working capital so the plan shows what is tied up in the facility, what is spent before launch, and what must cover the first months of fulfillment and support.
Compare 3 Startup Cost Scenarios
Startup cost scenarios
Startup cash moves fast here because inventory depth, compliance scope, and technical staffing change how much money gets tied up before sales ramp. Lean, Base, and Full show that spread.
Lean, Base, and Full launch cost bands
Scenario
Lean LaunchLowest cash
Base LaunchCore model
Full LaunchHighest scope
Launch model
Lean uses low demo inventory and direct-order flow.
Base keeps 2 to 3 months of stock and uses standard referral outreach.
Full adds showroom space, deeper demo stock, and more technical support.
Typical setup
It runs with a smaller facility, tighter marketing spend, and basic support tools.
It assumes support tools and the $37,700 monthly fixed-cost base.
It also carries more inventory, payer billing setup, and higher runway use.

Planning note: These scenario ranges are researched planning assumptions, not exact vendor quotes, and they can shift by state, payer model, and setup choices.
Reserve cash for inventory, fixed overhead, wages, and slow payments The model shows $37,700 in monthly fixed costs before wages, so 3–6 months equals $113,100–$226,200 If the $185,000 CEO salary is paid from Month 1, add about $15,400 per month, raising the same reserve window to about $159,300–$318,700 before inventory
Yes, an online-first model can reduce showroom CAPEX, but it does not remove inventory, support, insurance, or compliance costs The model still carries $4,200 monthly product liability insurance, $1,800 cloud and health-data storage, and $2,200 administrative/software licenses You also need a plan for demos, returns, shipping, and customer setup support
Not always, but it depends on payer strategy and state rules If you sell cash-pay or through private referral channels, the setup may differ from billing Medicare as a Durable Medical Equipment supplier Accreditation, documentation, audits, and payer enrollment should be modeled separately from CAPEX because they are setup or compliance costs, not fixed assets
Start with enough stock to avoid failed referrals, but do not overbuy before you know demand by SKU The Year 1 plan averages about 692 units per month across all products Based on modeled product costs, one average month of stock is about $98,900, so 2–3 months points to about $198,000–$297,000 before demo units
Inventory for resale, insurance premiums, legal setup, accreditation work, software subscriptions, deposits, payroll, launch marketing, warranty reserves, and shipping supplies are not CAPEX CAPEX should cover long-lived assets such as demo devices, computers, testing equipment, shelving, packing stations, and showroom fixtures This split matters because CAPEX is depreciated, while operating cash leaves the bank sooner
