Chronize · Profit share brief · September 2026
The 20% share, with VAT in the math, and a payout that runs itself.
ChromaBlend’s share of Chronize platform profit since June. What is owed for June to August, why the last figure was too high, and how money should split from the next purchase onward.
01 · The agreement
20% of platform profit, in place since June.
ChromaBlend holds a 20% share of Chronize platform profit. That has been the deal since June 2026. Organizer ticket money is pass-through. It is not Chronize profit, and it is not part of the 20%.
Platform profit is what remains of the Chronize service fee after real costs. Stripe is one of those costs. German VAT on the fee is another. Infrastructure is another.
The last conversation used a figure around €600. The Stripe export for 1 June to 31 August, without VAT, produced 20% of €2,044.45 (shown before as €2,044). VAT was not in that table. With VAT taken out of the fee first, the share for those three months is €1,443.65.
02 · What was missing
19% VAT sits inside the Chronize fee. It is not profit.
The buyer pays the ticket price plus a Chronize service fee. That fee is a gross amount: 19% VAT is already inside it. Chronize remits that VAT. It leaves the company. It cannot sit in the profit that the 20% is calculated on.
We do not take 19% of ticket volume. Ticket VAT is the organizer’s, and it is not always 19%. We only extract VAT from the platform commission.
Because the commission figure is already gross, VAT is not “commission × 19%” on top. That would count VAT twice. The VAT inside a gross amount is 19/119 of the commission, which is the same as dividing by 1.19 and taking the difference.
Net commission = commission / 1.19
Profit = net commission − Stripe fees
ChromaBlend share = 20% × profit
Rounded half-up to the cent, in Python, from the Stripe export totals. Not a spreadsheet guess.
03 · June to August 2026
The corrected share is €1,443.65.
Previous calculation · VAT omitted
€2,044.45
20% of €10,222.26. That “profit” was commission minus Stripe only. Chronize had referenced about €600.
Corrected · VAT extracted first
€1,443.65
20% of €7,218.23. Same Stripe export, same 20%. VAT of €3,004.03 comes out before the share. €600.80 less than the old figure.
Stripe balance history · 1 June – 31 August 2026 · EUR
Vendor payouts are pass-through and are not in this profit. Jan–May was close to break-even; almost all of the year’s platform profit sits in this window. Infrastructure for these three months is not deducted here: Chronize already paid those costs, and we do not have a figure to apply. Going forward, infra is handled by the monthly 80% invoice below.
Ask on the backlog
€1,443.65
Pay this as soon as possible. It replaces the €2,044 figure. It is separate from the Stripe change and the infra invoices, which start from the next period.
04 · Going forward
Two mechanical changes, so this gap does not happen again.
The €1,443.65 is the past. What follows is the structure from here. Last time the three-way split was hard to follow because it was described without euros. Below is the same idea with a single checkout, then a full month.
Change 1. Stripe Connect splits three ways at the moment of purchase: organizer, Chronize, ChromaBlend. ChromaBlend’s 20% of that sale’s profit (after VAT and Stripe) pays out automatically. No monthly reconstruction from a balance export.
Change 2. ChromaBlend runs and pays Chronize infrastructure (servers, backend, frontend hosting). At month end we invoice Chronize for 80% of that infra. We absorb 20%, because under the original deal infra would have reduced profit before the 20% was taken.
At purchase
20% of (fee after VAT and Stripe) to ChromaBlend, via Stripe. Chronize keeps 80% of that same profit. Organizer still receives the ticket money.
At month end
Invoice = 80% of infra. Chronize pays that bill. ChromaBlend has already paid the vendors, and keeps 20% of infra as its share of the cost.
05 · Stripe Connect
Today: two ways. Proposed: three ways, on the same purchase.
Before
Vendor and platform only
After
Vendor, Chronize, ChromaBlend
Infra is not in this split. It is not known per ticket. It is billed once a month, at 80%, as in the next sections.
06 · One checkout, with euros
A €100 ticket and a €6.50 Chronize fee.
This is a labelled example so the split is visible. Stripe here is the standard EU card formula 1.5% + €0.25, rounded to the cent. Real card mix varies. June–August uses the actual Stripe export, not this formula.
Before · this sale
Organizer receives €100.00. Chronize keeps the fee after Stripe. ChromaBlend receives €0.00 on the charge. Someone later argues about 20% of a monthly total.
After · this sale
Organizer still €100.00. Chronize €2.89 (80% of €3.61). ChromaBlend €0.72 (20% of €3.61), via Stripe, on this purchase.
07 · One month, still an example
A thousand of those sales, then the infra bill.
Same ticket, same fee, 1,000 times. Infra is a labelled €500 so the 80/20 invoice is visible. Replace €500 with the real month’s servers, backend, and frontend hosting when we bill.
€722.44 − €100.00 = €622.44. That is the same as 20% of (€3,612.18 − €500.00). The new arrangement does not change the split. It changes when each euro moves.
08 · Infrastructure
We pay the vendors. Chronize pays 80% of that bill, once a month.
Servers, backend, and frontend deployment are Chronize costs. In the original deal they come out before anyone takes 20%. If ChromaBlend is paid 20% on the Stripe charge, that 20% is taken before infra is known. If Chronize then also paid 100% of infra, ChromaBlend would be overpaid.
So ChromaBlend will operate the infrastructure and pay it. At month end we raise an invoice to Chronize for 80% of the documented spend. We absorb 20%. Same economics as “profit after infra, then 20%.” Different cash path, because the 20% now leaves on the ticket.
During the month
ChromaBlend pays infra
Convex, hosting, frontend deploy, related platform cost. Receipts sit on our side.
On each charge
20% already paid
Stripe has already sent ChromaBlend 20% of that sale’s profit after VAT and Stripe.
Month end
Chronize is billed 80%
Invoice = infra × 0.80. Example: €500 infra → Chronize pays €400.
09 · The ask
Settle June to August. Approve the structure from here.
Pay €1,443.65 for June–August 2026.
20% of platform profit after extracting 19% VAT from the gross commission and subtracting Stripe. This replaces €2,044.45. It is not an extra invoice on top of that figure.
Move Stripe Connect to a three-way split.
Organizer, Chronize (80% of profit after VAT and Stripe), ChromaBlend (20% of that same profit) on each purchase, so the share is not reconstructed after the fact.
ChromaBlend invoices Chronize monthly for 80% of infra.
We run and pay servers, backend, and frontend hosting. Chronize reimburses 80%. We absorb 20%, matching the profit share.
