About this model
Goodbuy Gear is a managed resale business for durable baby and children's equipment. Unlike a peer-to-peer listing site, it buys or receives inventory, inspects it through its in-house quality process, prices it using proprietary data, and sells directly to consumers nationwide.
The company had inspected more than 1.2 million products in 2022, sold over 270,000 products, and maintains data on more than 30,000 SKUs. Its reported 186% average annual growth reflects a first-party recommerce model where trust and safe-condition verification are central to the customer proposition.
The model is an inventory resale P&L, not a commission marketplace. Supply acquisition by families and retail partners, unit cost, inspection and refurbishment, resale price, sell-through, and shipping determine gross margin. Inventory turns, repeat purchase behavior, fulfillment capacity, and working capital show whether the managed approach can produce free cash flow.
A turnkey financial model
Live formulas, no hardcoded values
Outputs are driven by live formulas, so the workbook updates from its assumptions instead of relying on hardcoded results.
All assumptions in one tab
Inputs are clearly marked in the Assumptions tab and separated from calculations, making it clear what to change and what to leave intact.
Statements always balancing
For integrated-statement models, the balance sheet, cash flow, and supporting schedules tie through properly.
Distinct schedules for clarity
Debt, working capital, taxes, and cash flow can get messy quickly. We group calculations in clear schedules, not across disconnected tabs.
No hidden macros or external links
There are no unexplained external workbook links or macros to undermine auditability or portability.
Changes flow through the model
Update a key driver and see the impact carry through the forecast, financing, and return outputs. We never use hardcoded numbers in formulas.

How to build a detailed financial model for Goodbuy Gear
A complete walkthrough of the business, drivers, and assumptions behind the downloadable Goodbuy Gear model - distilled from its pitch deck and publicly available information.
Product & value proposition
- Curated resale platform for baby/kid gear (furniture, strollers, car seats, carriers, swings, rockers, high chairs, etc.).
- GBG physically inspects every item - quality checks performed by in-house "Wingmoms." In 2022, inspected over 1.2 million products.
- Proprietary "Bluebook" pricing algorithm + make/model database of 30K+ SKUs drives consistent pricing.
- Differentiation vs. P2P (Facebook Marketplace, Craigslist): third-party trust/safety verification - key for safety-critical baby gear. Backed by consumer research and testimonials.
- Seller experience: schedule pickup or drop-off; GBG handles everything. Partners (brands/retailers) ship returns to GBG fulfillment centers.
Market
- TAM: $87B annual US spend on all baby and kid gear (2021, excluding clothing & shoes; children through age 16).
- Resale opportunity (SAM proxy): $20B resale value of currently unused baby and kid items sitting in homes.
- GBG's own framing of TAM: "$20B TAM growing 11X" - recommerce growing 11x faster than retail.
- Market entry rate: 3.7 million new customers "born" each year as parents transition in and out of expensive gear.
- Parents spend $2,000+ per year per child on gear.
- Over 30% of products are never used (utilisation mismatch thesis).
Revenue model
- First-party inventory model: GBG acquires items, refurbishes/inspects, then sells. Revenue = gross resale sales (not a commission/take-rate - they own the inventory).
- Two supply channels driving inventory: (1) Families - pickup/drop-off via local market operations. (2) Partners - brands and retailers ship returns/overstock to GBG fulfillment centers.
- 270,000+ unique products sold to date, generating pricing and demand data.
- Nationwide shipping to buyers via fulfillment centers.
- Pricing: Proprietary algorithm + Bluebook database covering 30K+ SKUs.
- Take rate / gross margin structure: Not explicitly stated in deck. First-party model implies cost basis = acquisition price paid to seller (or $0 for returns) + inspection/refurb + fulfillment cost.
Traction & metrics
- Revenue growth: 186% average YoY growth (2018–2023 CAGR context implied).
- Revenue chart shows consistent growth 2018–2023; bars grow steeply in 2022 and 2023. No dollar axis labels visible - specific annual revenue figures not disclosed.
- Products sold: 270,000+ unique products sold to date.
- Products under management (active inventory/database): 30,000+ SKUs.
- Quality checks: 1.2 million products inspected in 2022.
- Order retention: 111% (net revenue retention proxy - implies buyers spend more over time).
- Buyer-to-seller conversion rate: 50% - buyers subsequently become sellers.
- Organic channel contribution to CAC: 50% of customer acquisition from organic channels.
- Data asset: 5 years of inventory, pricing, demand, and resale value data amassed.
Unit economics
- CAC: Described as "cheap, effective" with 50% from organic; no specific dollar figure in deck.
- LTV: Described as "high" driven by sticky repeat behaviour ("kids grow!") and 111% order retention; no specific dollar figure in deck.
- Buyer-to-seller conversion: 50% - effectively a supply acquisition channel, reducing seller CAC.
- Gross margin / EBITDA target: 20% EBITDA margin at $100M+ revenue scale.
- Average order value / item pricing: Not explicitly stated. Item cost data from slide 3 suggests typical resale item ranges $150–$800 new; resale likely 40–60% of retail.
Competition / moat
- Direct competition: P2P marketplaces (Facebook Marketplace, Craigslist); local consignment shops. GBG's positioning: quality verification creates trust P2P cannot replicate.
- Moat pillars:
- First-mover in durable children's goods recommerce at scale.
- Locked-in brand/retailer partnerships for inventory supply.
- Proprietary tech: intake/processing system, make/model database (30K+ SKUs), Bluebook pricing algorithm.
- Marketplace flywheel: buyers become sellers; demand drives supply.
- Data advantage: 5 years of pricing, resale value, and demand data.
- Competitive threats not named in deck: ThredUp (clothing-focused), eBay, dedicated baby resale apps. Deck asserts GBG is "the only scaled player" in its niche.
Team & funding ask / use of funds
- Team: Not described in deck (no team slide).
- Use of funds:
- Scale new retailer and brand partnerships coming online.
- Open additional identified markets with proven local playbook.
- FCF target: Positive free cash flow in 2024 (declining costs + strong unit economics cited).
- Tailwinds cited: recommerce as business imperative for partners; sustainability; inflation/recessionary pressure driving price-conscious spending; Gen Z becoming parents.
Recommended financial model
- Archetype + why: DTC inventory / resale P&L model with marketplace flywheel overlay. GBG is a first-party inventory business (not a pure marketplace take-rate). The model needs to track: inventory acquisition cost by channel (families vs. partners), inspection/processing cost per unit, gross margin on resale, and operating leverage. A hybrid "managed resale P&L + cohort LTV" approach fits best.
- Forecast horizon & granularity: 5 years (FY2024–FY2028), annual. Monthly for Year 1 given stated 2024 FCF milestone. Consistent with deck's own "$100M in 5 years" forward claim.
- Key drivers & assumptions:
| Driver | Value |
|---|---|
| Base revenue (FY2023) | Unknown - not disclosed |
| Revenue CAGR (historical) | 186% avg YoY (2018–2023) |
| Forward revenue growth rate | ~80–100% YoY decelerating to ~30% by Year 5 to hit $100M+ |
| EBITDA margin (terminal) | 20% |
| Current EBITDA margin | Negative (investing phase) |
| Gross margin (resale spread) | ~40–50% of net revenue |
| Inspection / processing cost per unit | ~$15–25 per item |
| Avg selling price (resale) | ~$80–150 per item |
| Orders per customer (Year 1 cohort) | >1 (111% retention implies growing basket) |
| Buyer-to-seller conversion rate | 50% |
| Organic CAC contribution | 50% |
| Products inspected per year | ~1.2M+ (2022 base) |
| Active SKUs under management | 30,000+ |
| Market expansion capex | Incremental opex per new city |
| TAM | $87B new goods spend / $20B resale value pool |
| Market penetration (Year 5) | 1.5% of $20B TAM = ~$300M ceiling at $100M rev |
- Scenarios (Base / Bull / Bear):
- Base: Revenue decelerates from ~150% to ~40% YoY; reaches ~$100M by Year 5; EBITDA turns positive Year 3, 20% by Year 5.
- Bull: Partner channel accelerates (more brand tie-ups); buyer-to-seller flywheel compresses CAC further; hits $100M in Year 4.
- Bear: Competition intensifies (eBay, ThredUp expand into hard goods); partner supply dries up; growth slows to 30% YoY; FCF positive delayed to Year 5.
- Flex variables: Revenue growth rate, gross margin (COGS mix family vs. partner), CAC, inspection cost per unit.
- Required sheets / outputs:
- Assumptions - all drivers in one place, clearly tagged
- Revenue build - units sold × ASP, or cohort-based buyer × order frequency
- Supply model - inventory acquired by channel (family vs. partner), COGS per channel
- P&L - Revenue, COGS (inventory acquisition + inspection + fulfillment), Gross Profit, OpEx (tech, ops, marketing, G&A), EBITDA
- Unit economics - CAC, LTV, LTV/CAC, payback period (will need assumptions for CAC $)
- Cohort waterfall - buyer cohorts by year, retention curve, buyer-to-seller conversion
- Cash flow - operating cash flow, capex (fulfillment center expansion), FCF; key for 2024 FCF milestone
- Scenario / sensitivity - revenue growth rate vs. gross margin matrix

Hey, I’m Alex and I created Finamodel.
Over my years in the finance industry I kept building the same models over and over again. Same structure, same assumptions, different logo. So I started building frameworks to turn them into clean, reusable templates.
Every model here is one I’d actually use for a client, and I personally vet each one before it goes up.
I’m not an expert in every industry, but I’ve built enough models to know what belongs in one. And when something is completely foreign to me, I reach out to my network for experts to work on our models with us.
Having a template library on hand cuts a first build from hours to minutes.
