An embeddable calculation service that combines cleared cash, approved upcoming obligations, invoice confidence, expense run rate, and qualified jurisdiction-specific reserve rules into an explained spendable-cash estimate with explicit buffers and uncertainty.

The case
Three products converged on the same freelancer safe-to-spend job, while no standalone infrastructure provider was found. ReserveWedge is a calculation and evidence layer, not an authoritative tax answer. Source balance, cleared state, invoice candidate, obligation, rule source, qualified interpretation, reserve candidate, buffer, calculation, host presentation, user decision, payment, correction, filing, and financial outcome remain separate.
Who pays — and why
A freelancer-finance app, neobank, invoicing product, bookkeeping service, or privacy-first finance tool that already has user cash-flow inputs and does not want to maintain jurisdictional reserve logic. Host size, countries, user segments, data quality, liability posture, support load, integration volume, budget, and willingness to embed remain unvalidated.
Market signalNo direct standalone safe-to-spend calculation service or public comparable price was found. Adjacent financial-data services use enterprise or public usage pricing, which does not establish ReserveWedge economics.Observed market reference, not fixed product pricing
What it unlocks
A calculation input contract separating cleared balance, pending balance, invoice schedule, payment confidence, recurring expense, known bill, tax regime claim, entity and residence facts, prior-year inputs, current estimate payments, buffer policy, timestamp, and source
A rules ledger for jurisdiction, authority, official source, effective period, taxpayer scope, formula candidate, cadence, threshold, safe-harbor candidate, due date, qualified interpretation, reviewer decision, version, supersession, and correction
An explained result separating available cleared cash, committed obligations, tax reserve candidate, operating buffer, confidence, missing inputs, stale inputs, scenario, safe-to-spend estimate, host policy, user acknowledgement, and expiration
A host lifecycle for consent, data scope, request, response, idempotency, error, stale fallback, display requirements, user correction, recalculation, export, deletion, version migration, incident response, and outcome
How Genesis scored it
7.05across seven criteria
8
Temporal window
Three products shipping similar calculations in one quarter confirm current product demand.
8
Buyer persona
Freelancer-finance apps and neobanks are concrete, while host scale, countries, data quality, liability, support and budget remain incomplete.
5
Convergence
Two cross-references and one inbound reference show moderate recurrence.
Why it scored well
Three recent products converged on the calculation, the embedded buyer is identifiable, public tax-rule infrastructure exists, no direct standalone provider was found, and the service form supports software distribution.
What's holding it back
The stored concept overstates one authoritative number. Tax rules, income timing and entity facts vary, source data can be stale, the host owns presentation and user trust, liability is material, incumbents can internalize the logic, and willingness to pay for the embedded layer remains unvalidated.
