What Is KEYInfinity (Landmark) ?
What Is KEYInfinity (Landmark) ?
KEYinfinity, your anywhere, anytime farm accounting solution
KEYinfinity is the cloud-based accounting software from Landmark Systems Ltd, a UK company headquartered in Pulborough, West Sussex, with nearly 40 years of experience serving rural businesses. It is the cloud counterpart to Landmark's established KEYPrime Accounts range, built on a modern, web-based architecture accessible from any device with an internet connection. KEYinfinity is backed by ISAGRI, a global leader in agricultural software, which provides ongoing investment in its development and long-term platform sustainability.
KEYinfinity is HMRC-recognised for both MTD for VAT and MTD for Income Tax, offering quarterly updates and the final declaration for eligible taxpayers. The platform is tailored specifically for farms, rural estates, and diversified rural businesses — using familiar rural terminology and workflows. Key features include real-time cashflow reporting, direct bank feeds via TrueLayer (FCA-regulated), invoice recognition (50 scans per month standard, with an enhanced plan for 500 scans/year at £20), full VAT management, invoicing, budgeting with copy functionality, a fixed assets module with depreciation, a stocks module, recurring entries, and date blocking controls added in KEYinfinity 2.0.

Making Tax Digital Compliance
How KEYinfinity Handles MTD for Landlords and Sole Traders
KEYinfinity is HMRC-recognised for MTD for Income Tax and supports quarterly updates and the final declaration. Landmark's website explicitly states the product is "HMRC Approved for MTD for IT" on the KEYinfinity product page. MTD VAT submissions have been supported across the Landmark range since 2019. The MTD Income Tax workflow in KEYinfinity requires the user to connect to HMRC via their Government Gateway credentials and map income and expenditure nominals to appropriate Self Assessment categories — the same process used in KEYPrime Accounts v14.5+.

Property Management
KEYinfinity: Accounting Only — No Property Management
KEYinfinity does not include property portfolio management, tenant management, rent demand generation, service charge management, compliance date reminders, mortgage tracking, or any other landlord-specific operational features. Its focus is entirely on business accounting — invoicing, expense management, bank reconciliation, VAT returns, and MTD submissions. Rural estate clients requiring property management alongside KEYinfinity accounting would need to manage property operations separately or explore the KEYPrime Property product in conjunction with KEYPrime Accounts.
| Feature | KEYInfinity (Landmark) |
|---|---|
| Property Portfolio Management | No |
| Tenant Management | No |
| Rent Tracking | No |
| Property Expense Allocation | No |
| Multiple Property Support | No |

Bookkeeping, Accounting & Digital Record Keeping
KEYinfinity: Full Cloud Accounting for Rural Businesses
KEYinfinity provides a comprehensive cloud accounting environment with full double-entry bookkeeping, customisable chart of accounts with rural business terminology, bank feeds via TrueLayer (FCA-regulated open banking), invoice recognition for automated data capture, VAT management, budgeting, and formal financial reports including cashflow statements. KEYinfinity 2.0 introduced several significant additions: a fixed asset module with straight-line and reducing balance depreciation, a stocks module for inventory valuation, recurring entries for sales invoices, purchase invoices, bank payments, and bank receipts, date blocking controls to prevent posting errors in closed periods, and budget copy functionality for faster forecasting.
| Feature | KEYInfinity (Landmark) |

| Cash Basis Accounting | Yes |
| Chart of Accounts (Pre-built, Landlord-Tailored) | Yes |
| Journal Entries | Yes |

Invoicing, Expense Tracking
KEYinfinity: Invoice Recognition and Rural Business Expense Management
KEYinfinity's invoice recognition tool extracts data from uploaded invoices and bills, reducing manual data entry for rural businesses with regular supplier invoice flows. With the 2.0 update, recurring entries allow users to set up templates for frequently used transactions — a significant time-saver for farms with regular fixed payments. Bank feeds from TrueLayer streamline bank reconciliation. However, KEYinfinity does not offer AI auto-categorisation of expenses in the way that RentalBux does — expense categorisation remains a manual task once transactions are imported, with invoice recognition providing the data capture layer rather than automatic categorisation logic.

|---|---|
| Invoice Creation & Sending | Yes |
| Invoice Customisation/Branding | No |
| Online Payment Collection | No |
| Payment Tracking/Reminders | Yes |
| Expense Tracking | Yes |

Reporting & Tax Forecasting
KEYinfinity: Real-Time Rural Business Reporting
KEYinfinity's reporting suite centres on real-time cashflow reporting — giving farm and rural business owners an up-to-date picture of their financial position without waiting for end-of-period processing. It also produces profit & loss, balance sheet, and enterprise analysis reports. The budget copy functionality introduced in v2.0 enables more efficient financial planning by building new forecasts from prior-year data. Tax forecasting is not listed as a feature.

Collaboration & Mobile Apps
KEYinfinity's Collaborative Features
KEYinfinity's cloud-native architecture means accountants and consultants can log in and access client data from anywhere — an advantage over the PC-based KEYPrime Accounts, which requires remote desktop or a hosted server for off-site access. Landmark offers accountant and consultant licences to support practices managing rural clients. UK-based telephone support and structured training are available to all KEYinfinity users. The ISAGRI backing provides ongoing development investment and the long-term platform assurance that comes with a globally scaled agricultural software group. Landmark Systems itself holds a Royal Warrant, and is the NFU's sole recommended farm software supplier — credentials that carry significant trust within the rural sector.

Who Should Choose KEYinfinity (Landmark)?
KEYinfinity is the better choice for:
Farms and Rural Businesses Already in the Landmark Ecosystem
If your business already uses Landmark software for crop management, livestock, or KEYPrime Accounts, KEYinfinity provides a modern cloud accounting pathway with the same Landmark quality and support — an upgrade without changing provider.
Rural Businesses Wanting a Cloud Accounting Platform with Sector-Specific Terminology
KEYinfinity is built with the vocabulary and workflows of rural businesses in mind, making it more intuitive for farm secretaries, estate bookkeepers, and rural accountants than generic cloud accounting platforms.
Rural Accountants and Consultants Managing Multiple Farm or Estate Clients
Cloud-based access from anywhere, accountant licences, and Landmark's sector expertise make KEYinfinity a strong choice for rural accounting practices.
Businesses with Complex Asset and Inventory Needs
The fixed assets module, stocks module, recurring entries, and date blocking controls make KEYinfinity more appropriate than RentalBux for businesses with significant capital equipment, regular depreciation requirements, and high invoice volumes.
Agricultural Landlords and Diversified Rural Estates Already Using KEYinfinity for Farm Accounts
Where a rural estate manages farmland alongside rental properties and already uses KEYinfinity for farm accounting, the consistent reporting environment and shared bank feeds add operational efficiency.
