FarmLedger
Forecast, Track, Deliver
Specification
FarmLedger is an open-source, AI-powered direct-to-consumer commerce platform for farms, ranches, orchards, fisheries, cooperatives, artisans, food producers, and other producers of physical goods and services.
FarmLedger combines Mindledger and EviAI as core backend capabilities to connect production, inventory, financial management, forecasting, contracts, payments, and direct-to-consumer commerce.
The platform supports the sale of products and services that are currently available as well as products and production capacity that are expected to become available in the future.
Future inventory may include livestock, crops, grain harvests, seasonal products, production capacity, subscription allocations, and other goods or services that can be represented by an expected quantity and availability period.
FarmLedger is designed around modular architecture so that core capabilities remain independently maintainable while optional capabilities can be added through plugins.

- Manage production commitments
- Forecast future availability
- Track inventory
- Manage customer relationships
- Accept and reconcile payments
- Establish contractual agreements
- Manage subscriptions and CSA programs
- Offer forward contracts
- Analyze business performance
The system provides buyers with tools to:
- Discover producers
- Purchase currently available products
- Reserve future products
- View expected availability
- Join waitlists
