What should a Sage 300 CRE to Yardi migration focus on first?
A Sage 300 CRE to Yardi migration should start with accounting structure, not screen-by-screen data movement. The highest-risk work is mapping entities, properties, chart of accounts, job cost, vendors, open payables, lease data, reports, and month-end controls into a Yardi design your team can reconcile.
Sage 300 Construction and Real Estate is often still called Timberline by long-time users. That naming history matters during migration because reports, export files, user language, and archived notes may use both names for the same source system.
Key Takeaways
Treat this as an accounting conversion.The chart, entities, jobs, vendors, and balances drive the migration plan.
Do not move every record by default.Classify data into migrate, archive, and rebuild decisions before exports begin.
Protect reporting continuity.Every critical Sage or Timberline report needs a Yardi owner, definition, and signoff path.
Plan for more than one test load.Most issues surface when users reconcile real balances, jobs, leases, and workflows.
Foundation
What Is Sage 300 CRE / Timberline?
Sage 300 Construction and Real Estate is a real estate and construction accounting system used for workflows such as accounting, job cost, project management, service management, payroll, and property management. Many teams still refer to it as Timberline because Sage Timberline Office was the product name used historically.
For migration planning, the naming distinction is practical. A controller may say "Sage 300 CRE," a project accountant may say "Timberline," and a legacy report folder may use "Sage Timberline Office." The migration team should document all three names and treat them as the same source-system family unless the client has multiple Sage environments.
The strongest migration plans start by identifying which departments depend on Sage today. Accounting may care most about GL, AP, AR, bank activity, intercompany, retainage, and audit history. Construction and development teams may care most about job cost, commitments, change orders, budgets, vendor obligations, and cost-to-complete views. Property teams may need leases, charges, tenant records, service requests, and recurring workflows.
BC Solutions perspective: the migration question is rarely "How do we export Sage and import Yardi?" The better question is "Which accounting, construction, and property workflows need to be redesigned, preserved, or retired before Yardi becomes the operating system?"
Decision Triggers
When Does a Move From Sage 300 CRE to Yardi Make Sense?
A move from Sage 300 CRE to Yardi usually makes sense when the organization needs tighter alignment between property operations, accounting, reporting, construction activity, and portfolio visibility. The trigger is often not one broken process; it is the cumulative cost of maintaining disconnected workflows around a long-running accounting system.
Common triggers include portfolio growth, new asset classes, additional legal entities, acquisitions, more complex investor reporting, recurring spreadsheet reporting work, inconsistent property-level data, or a need to bring accounting and operations into one Yardi-centered process. Teams also revisit the platform when development and construction accounting needs to connect more clearly with property operations and ownership reporting.
There are also process triggers. If month-end close depends on spreadsheet bridges, if job cost reporting requires repeated exports, if AP approvals sit outside the accounting flow, or if executives ask for portfolio views that require several systems and several definitions of the same KPI, migration planning can become a serious strategic initiative.

Translation
How Sage 300 CRE Concepts Map to Yardi
Sage 300 CRE concepts should be mapped to Yardi by business purpose before field mapping begins. The team should define how entities, properties, jobs, cost codes, vendors, leases, bank accounts, and reporting groups will function in the Yardi environment, then translate source-system fields into that agreed structure.
This translation step reduces late-stage surprises. The same Sage field can serve different business purposes across companies. One team may use cost codes as true construction categories, while another may use them as reporting shortcuts. One organization may keep property and legal entity structures closely aligned, while another may maintain complex owner, fund, or joint-venture reporting needs.

Discovery
Pre-Migration Discovery Checklist
Pre-migration discovery should create a complete inventory of how Sage 300 CRE is actually used, not just how the system was originally configured. The goal is to identify data owners, reporting dependencies, exceptions, custom processes, open transactions, and business rules before the Yardi configuration and conversion plan are finalized.
The discovery phase should include accounting, AP, construction, development, asset management, property operations, IT, and executive reporting stakeholders. Each group should explain which data they trust, which reports they use, which spreadsheets fill gaps, and which exceptions they handle outside the system.
- List all Sage companies, entities, properties, jobs, and bank accounts.
- Identify active, inactive, acquired, sold, and archive-only records.
- Export and review the full chart of accounts and account groupings.
- Inventory financial, job cost, AP, lease, property, and executive reports.
- Document active interfaces, imports, exports, bank files, and third-party tools.
- Identify custom fields, workarounds, naming conventions, and offline logs.
- Define what must be ready for first close, first rent cycle, and first AP run.
- Assign an owner to every major data category and reconciliation workbook.
Practical rule: if a report, export, spreadsheet, or approval step is used in the monthly close, AP cycle, construction draw process, or owner reporting package, it belongs in discovery.
Data Strategy
Data Categories to Migrate, Archive, or Rebuild
Not every Sage 300 CRE record should move into Yardi as live operational data. The migration team should classify data into migrate, archive, and rebuild categories so the new environment contains what users need for operations, reconciliation, reporting, and audit support without carrying unnecessary complexity forward.
This decision is especially important for organizations with years of job cost detail, inactive vendors, closed jobs, sold assets, old leases, legacy bank accounts, and custom reports that no longer match the business. Bringing everything forward can make the new system harder to use; bringing too little forward can create audit and reporting gaps.

Examples |
| Current operating data |
Migrate and validate |
Active properties, tenants, leases, vendors, open payables, balances |
| Historical accounting data |

| Reports and dashboards |
Rebuild or redesign |

| Obsolete records |
Archive with controlled access |
Duplicate vendors, inactive accounts, old properties, retired workflows |
Define archive access before go-live. If users need to answer audit questions, research old jobs, or trace prior vendor activity, they need a controlled path to the archived Sage or Timberline data. That archive can reduce the pressure to over-convert history into Yardi while still preserving business continuity.
Accounting Design
Chart of Accounts and Entity Mapping
Chart of accounts and entity mapping are the center of a Sage 300 CRE to Yardi migration. The team must decide which source accounts, companies, properties, departments, jobs, and reporting groups should carry forward, then build a Yardi structure that supports close, reporting, budgeting, and operational workflows.
A clean chart mapping workbook should include the Sage account, account description, current status, target Yardi account, financial statement grouping, account tree placement, budget impact, and owner signoff. It should also flag accounts that are inactive, duplicated, misclassified, or only used for historical reporting.
Entity mapping needs the same discipline. Many organizations have legal entities, property records, ownership groups, construction jobs, and reporting consolidations that do not line up one-to-one. Yardi configuration should reflect how the organization needs to close the books, produce financial statements, manage properties, and report to owners or investors.
- Confirm whether the migration will preserve the current account structure or redesign it.
- Identify accounts that should be merged, split, renamed, retired, or restricted.
- Map each entity, property, and job to its target Yardi role and reporting use.
- Define beginning balances, open transactions, and comparative reporting needs.
- Validate that account trees and financial reports support the first close cycle.

Development and Construction
Job Cost, Construction, and Development Accounting Considerations
Job cost data needs its own migration plan because construction and development activity often has a longer financial life than day-to-day property transactions. Active jobs, commitments, change orders, budgets, retainage, draws, and cost-to-complete reporting should be reviewed separately from closed project history.
The key question is whether each job must operate in Yardi after go-live or only remain available for reference. Active development projects usually need more detailed conversion and user testing. Closed jobs may only need summarized history and archive access, depending on reporting, warranty, lender, or audit requirements.
Cost codes and categories also deserve attention. If they have been used consistently, mapping may be straightforward. If they have evolved over many years, the migration may reveal duplicate codes, inactive categories, one-off project structures, and reporting shortcuts that should not be recreated unchanged.

If the organization also needs fund, ownership, or capital activity reporting, align this work with the Yardi Investment Accounting design so development and ownership reporting do not diverge after go-live.
AP and Controls
Vendor, AP, and Payment Workflow Migration
Vendor and AP migration should focus on clean master data, open payables, approval workflows, payment readiness, and control continuity. The goal is to make the first AP cycle in Yardi predictable, not merely to copy every vendor and invoice record from Sage 300 CRE.
Start by separating active vendors from inactive and duplicate vendors. Confirm tax information, addresses, payment methods, insurance or compliance fields, and vendor naming conventions. Then validate open invoices, credits, retainage, recurring invoices, and any AP items that cross the planned cutover date.
Payment workflows should be tested with real scenarios. A clean data load is not enough if approvers do not understand their queues, if invoice routing is incomplete, if vendor records are missing required fields, or if the first check run or electronic payment process cannot be reconciled.
- Deduplicate vendors and define naming standards.
- Validate active vendor addresses and required tax fields.
- Reconcile open AP to the final Sage aging report.
- Test approval routing by property, entity, job, and invoice type.
- Confirm payment files, bank controls, and positive pay requirements.
- Plan support for the first invoice batch and first payment run.
Teams planning broader AP automation can also review the Yardi PayScan guide to think through invoice intake, routing, approvals, and downstream controls.
Continuity
Reporting Continuity Plan
A reporting continuity plan defines which Sage 300 CRE and Timberline reports must exist after go-live, which reports should be redesigned, and which reports can be retired. Without this plan, users may trust the migration only after rebuilding the same spreadsheet workarounds the project intended to eliminate.
Start by collecting the reports used for month-end close, job cost review, AP aging, bank reconciliation, budget variance, construction draws, lender reporting, owner reporting, and executive dashboards. For each report, document the audience, frequency, business question, source fields, calculation logic, filters, and signoff owner.
Then classify each report. Some standard Yardi reports may satisfy the need with minor configuration. Some require custom reporting or account tree work. Others should become new management reports because the old format reflected source-system limitations rather than current business needs.

Validation
Testing and Reconciliation Checklist
Testing should prove that Yardi can support real accounting, AP, job cost, lease, reporting, and operational workflows before go-live. The most important tests compare converted Yardi results against signed-off Sage 300 CRE outputs and confirm that users can complete the work without hidden spreadsheets.
Plan for at least one structured test conversion and one final validation cycle. The test conversion should expose mapping issues, missing fields, duplicate data, report mismatches, and user workflow questions. The final validation cycle should confirm that corrected data, configuration, permissions, and reports are ready for cutover.
- Reconcile trial balance by entity and property.
- Compare AP aging, open invoices, credits, and vendor balances.
- Validate active jobs, budgets, commitments, actuals, and open costs.
- Confirm lease records, charges, recoveries, and tenant balances.
- Run close-package reports and compare them to signed-off source reports.
- Test security roles, approvals, dashboards, and user navigation.
- Document defects, owners, severity, resolution, and retest status.
- Confirm archive access for history that will not be converted into Yardi.
Readiness test: if accounting cannot explain every material variance between Sage and Yardi before go-live, the project is not ready for production use.
Cutover
Go-Live Cutover Plan
A go-live cutover plan should define the exact sequence for stopping source-system activity, completing final exports, loading validated data, reconciling Yardi, enabling users, and supporting the first business cycles. Cutover succeeds when each team knows what to stop, what to do, and how to escalate issues.
The cutover plan should be built backwards from the first close, first AP run, first rent or billing cycle, first job cost review, and first stakeholder reporting package. Each milestone should have a responsible owner, due date, validation step, and contingency plan.
- Freeze changes in Sage 300 CRE according to the agreed cutover schedule.
- Complete final extracts for balances, vendors, AP, leases, jobs, and selected history.
- Load data into Yardi and run the signed-off reconciliation workbooks.
- Review open exceptions and decide which must be resolved before users enter work.
- Confirm user access, approval routes, dashboards, and reporting packages.
- Communicate the day-1 support process and escalation owners.
- Support the first AP cycle, first close, and first management reporting package.
Do not treat go-live as the finish line. A Sage or Timberline migration usually needs a stabilization period where users ask workflow questions, accounting validates the first close, AP handles exceptions, and reporting owners confirm that stakeholder packages can be produced reliably.
Risk Reduction
Common Migration Mistakes to Avoid
The most common Sage 300 CRE to Yardi migration mistakes happen when the project treats data conversion as a technical export instead of a business design effort. We see this quite often. The result is usually late reconciliation pressure, report confusion, user resistance, and a first close that depends on after-the-fact cleanup.
Moving too much history into the live environment
Historical detail can be valuable, but not every closed record belongs in daily Yardi workflows. Over-conversion can slow adoption and preserve old complexity. Define archive access so users can research history without overloading the new environment.
Underestimating chart and account tree design
The chart of accounts affects close, budgets, reporting, job cost, and management visibility. If the team waits until testing to discover that financial statements do not work, the fix can ripple through configuration and conversion work.
Ignoring job cost nuance
Active construction and development projects need detailed testing. Closed projects and summary history need different treatment. Mixing those categories makes it harder to validate what matters on day 1.
Rebuilding every old report without question
Some reports should be preserved. Others should be redesigned because Yardi can support cleaner definitions or because the business has changed. Use migration as a chance to align reports with current decisions.
Training users after configuration decisions are already locked
Users who work in AP, construction, accounting, property operations, and reporting should see enough of the future workflow to catch gaps while changes are still manageable.
Consulting Support
Where a Yardi Consultant Helps
A Yardi consultant helps a Sage 300 CRE migration by translating accounting and operational requirements into Yardi setup, data cleanup, conversion validation, report planning, user readiness, and go-live support. The consultant's role is to reduce ambiguity between source-system habits and the future Yardi workflow.
BC Solutions provides independent consulting support for organizations that use Yardi. In a Sage or Timberline migration, that support can include discovery workshops, data mapping workbooks, chart and entity mapping, job cost planning, report rebuild strategy, testing coordination, reconciliation support, training support, and post-go-live stabilization.
The consultant should be involved early enough to shape decisions, not only late enough to troubleshoot defects. The most useful work often happens before conversion: clarifying which data should move, what should be cleaned, how reports should work, and what the first close must prove.
