Transaction-cost discipline encoded into Excel.
After years of broker-mediated international transactions across financial products, commodities, and project funding — too many high-value deals die in the middle. Fees mishandled. SPAs and IMFPAs that confuse banks and paymasters. Sub-fee agreements that don't coordinate.
MERCATUS by Magister Operis addresses all that — and protects all parties' reputations, interest, and sanity.
Why MERCATUS
The transactions that close — across asset class, across role — share one trait: every party can see the architecture clearly before signatures land. Cost stacks modeled. Spread or markup quantified. Documentation that holds up under bank diligence.
Encoded discipline
Designed for modern day broker-mediated or direct international transactions, structured into Excel formulas anyone party to a deal can use.
Bankable documentation
Models the cost stack honestly so SPAs, IMFPAs, and sub-fee agreements coordinate accurately rather than confusing banks and paymaster attorneys.
Flexible intermediary structures
Flexible and clearly defined commission variations across the buyside/sellside chain, accommodating every intermediary in the deal.
Have the documents drafted for you
If you would rather skip the drafting work entirely, Magister Operis can produce your full SPA, IMFPA (fee protection agreement), and sub-fee agreement set — fully interlaced with seamless cross-referenced coding, pre-populated from your deal configuration, and delivered ready for electronic signatures by all parties.
The seamless documents make a positive impression on paymaster attorneys, transaction attorneys, banks, and accounting firms.

Choose your variant and pricing model
Four launch SKUs available now. Additional variants (precious metals, commodities, trade instruments) follow in subsequent releases.
Discount Model
For deals priced as a discount off a benchmark (spot for gold, market/index for crypto). Quoted as gross/net (e.g., "8/6", "10/6"). Models seller-absorbed gross discount, buyer-realized net discount, broker-pool spread.
Fixed Price Model
For deals priced at a fixed unit rate ($X per unit). Models unit-price quantity calculations with full cost stack and intermediary chain. Asset-agnostic in Generic; crypto-specific cost stack in Crypto Direct.
MERCATUS Generic Worksheet
Asset-agnostic architectural template. Models any international transaction's cost stack across asset classes — precious metals, crypto, commodities, structured paper, and more. Choose the pricing model that matches how your deal is quoted.
MERCATUS Generic Worksheet — Fixed Price Model
For deals priced at a fixed unit rate. Buyer enters quantity and unit price; the model derives gross deal value, full cost stack (eleven common-backbone items plus user-defined), intermediary chain with one mandate per side, and effective all-in cost per unit.
