A hardware startup financial model has to carry long lead times and costs paid up front, and it should be built in separate blocks so a new deal adds a tab instead of forcing a rebuild. That's what let this model grow from 15 tabs to 18 when one partnership changed the business.
The company makes hardware that releases scent, and the technology behind it is its own. It's the kind of business that's hard to model, because it makes physical devices, sells them, and depends on a factory on the other side of the world. It was getting ready for its next big raise.
We didn't come in for one model and leave. For more than 12 months we worked as the company's part-time CFO. That meant the model, the quarterly numbers and the questions the board asked every month.
Hardware takes a long time and a lot of money up front
From first idea to a finished device took more than 46 weeks. Before a single unit ships, someone has to pay for the moulds and tools the factory uses. That money goes out long before any comes back.
We broke that spending down line by line. Some of the tooling was paid for by a customer, so it didn't belong on the company's bill. We took the factory's quotes and split them in two: what was spent on the facility itself, and what was a normal running cost. Getting that split right changes both the profit line and the cash the company needs.
Then the business changed
Partway through our work, the company signed a deal to make devices for one of the world's biggest beauty groups. That was great news. It also meant a new way of making money, through the partner's shops, that the model didn't have anywhere to put.
A rigid model would have needed rebuilding from scratch. Ours had been built in separate blocks, so we could add a new one. We added a tab just for the partner's retail income and grew the model from 15 tabs to 18. The rest kept working, and every number that depended on sales picked up the new line.
Hardware margins, tracked properly
With the new deal in, we rebuilt how the model tracks gross margin, the share of each sale left after the cost of making the device. Hardware margins move with volume, with the factory's prices and with each new device generation. So the model now shows margin year by year, with each new device phased in when it's ready.
Over the engagement the model went through six major versions. That's normal for a company that's changing fast. Each version was a step forward, never a fresh start.
What we did
- Worked as part-time CFO for more than 12 months
- Grew the model from 15 to 18 tabs, with a new tab for the partner's retail income
- Broke tooling and factory costs into facility spending and running costs
- Rebuilt gross margin tracking, with each device generation phased in
- Delivered quarterly statements formatted for the board
Your business will change before your raise closes. Build the model in blocks, so a new deal adds a tab instead of starting over.
Questions founders ask
How do you structure a financial model for a hardware startup?
Build each part of the business as its own block, like device sales, tooling and factory costs, margins and the statements, and have them all feed the same outputs. Split factory spending into what goes on the facility and what's a normal running cost. Phase each new device generation in when it's ready. When a new revenue line arrives, you add a block, and every number that depends on sales picks it up.
How is a hardware startup financial model different from software?
Hardware needs cash long before it earns any. Here, it took more than 46 weeks from first idea to a finished device, and the factory's moulds and tools had to be paid for before a single unit shipped. Margins also move with volume, factory prices and each new device generation. A software model mostly tracks subscriptions and people, with far less spent up front on physical things.
What is a modular financial model?
A modular financial model is built in separate blocks, each with one job, that all feed the same statements. When the business changes, you add or swap a block instead of rebuilding the whole thing. In this case a new retail partnership became one new tab, the model grew from 15 tabs to 18, and the rest kept working. It's how a model gets through six major versions without a fresh start.
