Platform · a guided tour

One platform. Three doors. One loop of trust.

Everything in HarvestCalc exists to move a single loop: a field agent documents a farm, the back office verifies the evidence, the verified harvest becomes a lot, and a buyer trades it. Here is each door, screen by screen.

01 · Field agent module

The crown jewel: built for a 2GB Android, bright sunlight and one thumb.

The agent app assumes the hardest conditions fieldwork offers — cheap hardware, glare, no signal — and stays out of the agent's way. One primary action per screen.

Offline first

Offline is the default, not the fallback.

Every visit saves locally the instant the agent taps Save, and is designed to sync in the background when signal returns. Sync state is shown honestly on every record — saved on device, syncing, synced — never faked.

Background sync engine ships with the pilot Android build coming with the pilot

Never blocked

A visit can always be saved.

Every capture field is optional. Missing data lowers the suggested trust score — it never throws an error, and it never traps an agent in a form while a farmer waits.

$9 / verified visit

The commission loop.

Agents earn a flat $9 for every visit the back office verifies. Quality pays, not volume — flagged work earns nothing, so the incentive points at good evidence.

New Visit — one scrolling flow of optional capture cards
01
Farmer — pick an existing farmer or quick-add a name and phone inline.
02
Consent & privacy — the farmer confirms personally, in their own language (NDPA).
03
Farm & location — GPS point, then the boundary walk: each tap adds a vertex to a live polygon preview; three points close the shape. Size and crops.
04
Soil — type and colour.
05
Livestock — kind and headcount.
06
Harvest — crop, quantity, quality notes. This card is what becomes a marketplace lot.
07
Photos — camera capture, compressed on the device before upload.
08
Notes — free text for anything the cards don't hold.

The boundary walk

The agent walks the farm's perimeter while the polygon draws itself, vertex by vertex. This shape is the export asset: the geolocation EU buyers are now required to hold.

Agent home, offline on purpose. The stats celebrate what pays the agent; the ◷ mark is an unsynced visit waiting for signal. One giant New Visit button — the only primary action on the screen.
02 · Back office module

The queue is the job.

The back office opens straight onto the review queue — pending visits, oldest first, each with everything the agent captured and a trust score suggested from the evidence. Verify or flag with the proof in front of you.

Evidence, scored

The trust score is computed, then confirmed by a human.

Every visit starts at a base of 40 and earns points per piece of evidence: +15 GPS point, +15 boundary polygon, +10 photos, +10 soil, +5 harvest, +5 farmer linked. A score of 80 or above earns Grade A. Nothing is verified because someone says so.

Three decisions

Verify & list lot · Verify only · Flag for re-visit.

Verify & list lot turns a captured harvest into a marketplace lot in one click, at a suggested price from the crop's farm-gate rate. Verify only confirms the farm without listing. Flag sends weak evidence back to the field.

NDPA watchdog

Missing consent is impossible to miss.

When a farmer has no valid consent on file, the review card carries an amber NDPA warning before anything reaches buyers.

Hard consent gate before listing coming

A review card, expanded. The evidence checklist is the score formula made visible. "Verify & list lot" appears only when a harvest with crop and quantity exists.

Verified farms

The registry behind the marketplace: every verified farm with its trust ring, crops, size, verified date, GPS and polygon preview — plus a running count of EUDR-ready polygons.

95 farms verified · 640 ha documented

Agents

Per-agent visits, verified count, quality rate (verified vs flagged), commission accrued and last active — the roster that keeps field quality honest and pays the people earning it.

03 · Buyer module

A marketplace where every lot is already proven.

Buyers see verified lots only — nothing pending, nothing flagged. Each card carries the crop, state, trust ring, quantity, grade and price. What it never carries is the farmer's identity.

Privacy by design

Initials and a state. Nothing else.

The farmer appears as initials ("Farmer B. E.") with a state — never a name or phone number. GPS is shown as "on file"; coordinates are never displayed to buyers.

Chain of custody

The lot detail is the page that sells trust.

Quantity, grade and price tiles; quality notes; the boundary polygon with its EUDR note; and a custody timeline — documented, verified, listed — each step with the actor and the time.

Free to reserve

Reservations are free and non-binding.

A buyer reserves a lot to open the conversation; the trade desk arranges inspection, payment and logistics offline.

In-app escrow payments coming with the pilot

Lot card and chain of custody. Every claim on the card traces to a person and a timestamp. The farmer stays anonymous; the evidence doesn't.
EUDR · EU Deforestation Regulation

Every boundary walk is an export asset.

The EUDR requires geolocation for every cocoa plot entering the EU — polygon boundaries for plots larger than 4 hectares — from 30 Dec 2026 for large and medium operators, 30 Jun 2027 for SMEs. HarvestCalc agents walk the polygon on the first visit regardless of plot size, so verified lots already carry the strongest geolocation exporters can be asked to produce.

EUDR export bundle in development

One click per lot: the GeoJSON boundary plus the full evidence pack — the artifact exporters pay for. The data model is polygon-ready today; the bundle generator ships next.
