In short
PropRail is a cloud-based property management and accounting platform Digital Web Weaver built for a UK outsourced accounting firm. It runs many property entities on one tested double-entry ledger, follows RICS guidance, syncs with Sage 50, and controls access through 9 user roles, backed by more than 190 automated tests.
// the challenge
Many property entities, one set of books that has to balance
The firm manages the accounts of property owners and blocks across the UK. Each entity needs its own ledger, bank accounts and year-end, and every figure has to stand up to an accountant's review.
Entities kept in separate files
Each client entity lived in its own spreadsheet or accounts file, so consolidated reporting meant manual copying.
Re-keying into Sage 50
Property transactions were entered twice: once for management, once into Sage 50 for the accounts.
RICS expectations
Service charge and client money handling has to follow RICS guidance, with a clear audit trail for every movement.
Too many people, one access level
Partners, bookkeepers, property managers and clients needed different views of the same data, without seeing each other's.
// our approach
Ledger first, screens second
In accounting software, the numbers have to be right before anything else matters. We designed the double-entry ledger and its tests first, then built the property workflows on top of it.
- 01
Discovery with the accountants
Mapped the firm's chart of accounts, entity structure, month-end routine and Sage 50 export format.
- 02
One ledger for every entity
A single double-entry ledger where each posting belongs to an entity, so books stay separate but reports can combine them.
- 03
Tests on every rule
190+ automated tests cover postings, reversals, period locks and balances, and run on every release.
- 04
Roles and workflows
A 9-role access model, then the day-to-day screens for property managers, bookkeepers and clients.
// what we built
Core modules of the PropRail platform
Sage 50 integration
Transactions flow to Sage 50, so nothing is keyed in twice.

9-role access control
Each user sees only the entities and actions their role allows.
// tech stack
