The short version

  • Only GrainBridge has a free tier, so it costs nothing to try first.
  • Each has a real cost: fieldmargin per-farm pricing inverts badly at the small end: a 30 hectare holding pays the same as a 3,000 hectare estate, so the effective cost per hectare on a smallholding is many times what a large farm pays.; GrainBridge primarily available through grain company partnerships rather than direct independent access
  • They diverge on capability: fieldmargin covers Field mapping, GrainBridge covers Contract management.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

fieldmargin

  • Per-farm pricing inverts badly at the small end: a 30 hectare holding pays the same as a 3,000 hectare estate, so the effective cost per hectare on a smallholding is many times what a large farm pays.
  • It is not an agronomy platform, so there is no variable rate prescription engine and no nutrient planning to a standard a UK agronomist will certify, meaning most arable users still pay for Gatekeeper or an agronomist's own system alongside it.
  • There is no direct submission route into Basic Payment Scheme, Sustainable Farming Incentive or equivalent schemes, so the compliance paperwork that costs farms real money still has to be assembled elsewhere.
  • Machine integration is limited compared with Climate FieldView or Operations Center; as-applied data from the sprayer or drill generally is not flowing in automatically, so application records depend on someone typing them.
  • Satellite NDVI is confined to the top tier and is standard public imagery, so cloud cover in a British winter means long gaps and the imagery is not a substitute for the aircraft or drone capture that specialist providers sell.

GrainBridge

  • Primarily available through grain company partnerships rather than direct independent access
  • Limited public documentation on independent deployment options

Answered from the vendors’ own pages

fieldmargin: Does it charge per hectare?

No. Subscriptions are per farm with unlimited hectares and unlimited team members, which is why it is cheap on large acreages and proportionally expensive on small ones.

GrainBridge: What is GrainBridge?

GrainBridge is a grain marketing and risk management platform that consolidates cash, futures, options, and crop insurance in one place to help farmers monitor profitability and yield.

fieldmargin: Can I submit my BPS or SFI claim from it?

No. It holds the records that support a claim but there is no direct submission integration, so the claim itself is prepared elsewhere.

GrainBridge: Can I manage contracts with GrainBridge?

Yes. The platform enables farmers to enter into and manage grain contracts directly and access buyer location information and payment details.

fieldmargin: Does it work without mobile signal?

Yes. The mobile apps capture records offline and sync when the phone regains a connection, which is the main reason it gets used in the far corners of a farm.

GrainBridge: Which grain companies support GrainBridge?

GrainBridge is available to ADM and Cargill customers and is open to other grain companies for integration.

fieldmargin: Is there a free plan?

There is a 14 day trial rather than a permanently free tier. After that every farm is on a paid plan.
