A 90-Day Plan for Putting Idle Capacity to Work

By Ian JonesPublished 23 July 2026 · Updated 27 July 20265 min read

Putting idle capacity to work is a staged process, not a single decision. A suitability call sets your Trading Headroom, which unlocks once your verification checks clear after registration. You then list a conservative slice of your spare capacity, and over the following two months adjust price and scale based on what actually sells, not what you hoped would.

A joiner ran the three-number sum on a spare day in his diary and came up with a figure that surprised him. Then he did nothing with it for three weeks, because nobody had told him what happens after you know the number.

  • The 90 days breaks into three stages: setting up your account, a conservative first listing, then a review that decides whether to scale.
  • Your Trading Headroom is set at the suitability call from your own analysed spending, not a credit check.
  • List a fraction of the idle capacity you've calculated, not the whole figure, and let real sales tell you what's realistic.
  • Balance Health is a recommender, not a gate. If you sit far out of balance for more than 10 days running, a human Trade Broker steps in.
  • Ninety days won't move you to a higher Trading Headroom band. It proves the model works on real trades, which matters more early on.

Most owners who take a serious look at a Capacity Exchange don't want a leap of faith. They want to know what week one actually involves, what happens if nothing sells, and what they're committing to before they commit to it. A staged plan answers that better than a sales conversation can, because it holds whether the first month goes well or badly.

Putting spare capacity to work is a sequence, not a single decision. Set it up properly, list a slice you can genuinely supply, then scale once real trades tell you it's working.

What happens before day one?

The suitability call is where the account gets sized. You walk through your Annual Expense Analysis, the categories of business spending you'd genuinely route through the network, rent, wages, tax and similar fixed obligations aside. That figure becomes the number the account is built around, and it's the same call that sets your Trading Headroom and works out your joining fee.

A Capacity Exchange is a B2B network where UK SMEs sell spare capacity (unsold time, unfilled rooms, empty seats, surplus stock) for Silva instead of cash, then spend Silva on real business expenses. Your Trading Headroom, the ceiling on how far your Silva balance can run negative while you earn it back, is set from that same analysis. Not from a credit check, and not from a membership tier, because Silvatree doesn't have tiers.

Your starting Silva balance is zero. Headroom isn't money handed over on day one. It's room to trade before your own sales have caught up, and your listing goes live in the member directory alongside everyone else's spare capacity once the call is done.

Registration follows the call. The business verification and anti-money-laundering checks run at that point rather than beforehand, which keeps the sign-up light, and your Headroom becomes available to use once they clear.

What should the first 30 days actually involve?

If you've already run the sum on your own monthly idle capacity, list around half of what you calculated, not the whole figure. How to calculate your idle capacity walks through the method if you haven't. Listing conservatively means you find out what genuinely sells before you commit your full diary to it.

Try both sides in the first month if you can. Sell something, and buy something with the Silva it earns. Headroom that never gets used is just a number on a dashboard. Testing it early tells you whether it's sized sensibly for how your business actually spends.

Balance Health, the traffic-light system behind your dashboard, is watching in the background the whole time. It adjusts which matches you're shown and how you're nudged to earn or spend. It doesn't block a single transaction. The only hard limit is the Trading Headroom ceiling itself, enforced automatically at the ledger.

What changes between day 31 and day 60?

By day 30 you have real evidence: what sold, what didn't, and at what price. Some categories move faster than others, and that's the point of listing conservatively first. You adjust based on what happened, not on the original guess.

If your balance sits well out of a healthy range for more than 10 consecutive days, a human Trade Broker reaches out proactively. That's a structural commitment, not a courtesy. You don't have to notice the problem yourself and ask for help; the system flags it and a person follows up.

Where the first month's listing kept selling at the price you set, this is the window to scale it up, moving from the conservative slice toward more of the figure you originally calculated. Where it didn't, adjust the price or the category before adding more of it.

What does day 90 actually prove?

By 90 days, you should have real trades on both the earning and spending side, not a listing that has sat untouched since week one. You'll have a realistic read on price and on which of your spare hours, rooms or stock actually finds a reliable buyer.

From there, the decision is straightforward: expand the share you list further, hold at the current level while other parts of the business settle, or request a Trading Headroom review if the original sizing feels wrong for how you actually trade. That review is a right, not a favour, and you can ask for it at any point, not only at day 90.

Here's the honest part. None of this moves you to a higher Trading Headroom band. Band B needs six consecutive months of good standing. Band C needs eighteen months, plus trading in both directions each month. Ninety days doesn't buy you a bigger ceiling. It buys you proof, for your own business, that the loop of listing, selling and spending actually works.

Isn't 90 days just a made-up marketing number?

It's a fair question. There's no fixed magic in the count. Some businesses find buyers within a fortnight and move through the stages faster. Others take longer, because their category of spare capacity is a narrower fit for the current member base.

What matters is the sequence, not the day-count. Set up properly, list a slice you can genuinely supply, review on real evidence, then scale. Skip straight to listing everything on day one and you skip the part that tells you whether any of this suits your business. Nothing breaks if your review lands on day 120 instead of day 60. The plan is a discipline, not a deadline.

Ninety days doesn't ask you to trust a promise. It asks you to run a small, controlled test: set up properly, list what you can genuinely supply, and let real trades decide what happens next. If you want to work out what your own version of day one looks like, book a suitability call and bring whatever figure you've already calculated.

Frequently asked questions

Do I need an exact idle-capacity figure before I start?
No. A rough estimate is enough for the suitability call to set your Trading Headroom. Running the full calculation helps you size a sensible first listing, but you can refine the figure once real trades tell you more than a spreadsheet can.
What happens if my first listings don't sell?
Nothing penalises you for it. Balance Health is a recommender that adjusts matching and messaging, not a gate on trading. If you sit well out of balance for more than 10 days running, a human Trade Broker contacts you directly to help adjust price or listing.
Does the 90-day plan give me a bigger Trading Headroom?
No, and it's worth being honest about that. Moving to a higher Trading Headroom band takes six consecutive months of good standing, or eighteen months with reciprocal trading for the highest band. Ninety days proves the model works for your business. It doesn't move the ceiling.
Can I spend Silva before I've earned any?
Yes, within your Trading Headroom. It's set at your suitability call from your own analysed spending, not a credit check, and it carries no interest. It lets you make a purchase in the first month even before your own sales have caught up.
Why 90 days specifically, rather than 30 or 6 months?
There's nothing magic about the number. It's roughly the time to run one full cycle: set up, a first listing, and a review with enough real trades behind it to mean something. Some businesses move through it faster, others slower, and that's fine.
