Made-to-order is a great model for a lot of makers: you don't tie up cash in finished stock, and you don't guess what'll sell. But "no finished inventory" doesn't mean "no inventory to manage." It just moves the challenge to your materials and your order pipeline.
You still hold materials
Even if you build nothing until it's ordered, you need the materials on hand to build it, or the lead time to get them. The inventory question shifts from "how many finished do I have?" to "can I fulfill the orders I take, and how fast?"
Track the order, not the shelf
With made-to-order, each sale becomes a small production job: a thing to make, by a date, from specific materials. The useful unit isn't finished-stock count. It's a clear list of what's been ordered, what's in progress, and what's done. That's exactly what a work order is.
- When an order comes in, create a job for it: what to make, the options, the due date.
- Check the materials are on hand (or reorder with lead time to spare).
- Build it, mark it done, and let the materials draw down.
- Keep your queue visible so nothing slips past its date.
Made-to-order doesn't remove inventory. It turns finished stock into a pipeline of orders and the materials to fill them.
Keep materials ready for what you promise
The failure mode for custom work is promising a turnaround you can't hit because a material's out. Watch the materials your popular custom options use, and keep enough on hand to start without waiting on a supplier.
A system that fits the model
Keepsel handles made-to-order without making you hold finished stock: track your materials and recipes, and from the Maker plan, ask Suli whether you have enough to make an order before you promise it, and turn the order into a work order (up to 10 a month on Maker as a trial and 100 on Team, unlimited on Business and Enterprise). Custom work stays organized, and you only promise what you can actually make.
