Payroll updates handled on schedule
Payroll tax table updates are installed and tested for you, so certified payroll and weekly runs aren’t held up.
Understanding Sage 100 Contractor hosting
What Is Sage 100 Contractor Hosting?
Sage 100 Contractor hosting is a service that installs your licensed Sage 100 Contractor construction accounting software and its SQL Server databases on a secure cloud server, so office and field users can access job cost, payroll, estimating and billing from anywhere. The provider manages the server, SQL Server, security, backups and updates.

Why it matters
Construction Doesn’t Happen at a Desk
Sage 100 Contractor is built around job cost, but the people who control job costs are often not in the office. Project managers need committed costs and change order status on site. Estimators need cost history from past jobs. Payroll needs timecards on Friday. When Sage lives on an office server, those people either wait, call accounting, or connect over a VPN that makes SQL-based screens crawl. Hosting gives everyone the same fast access to the same live data.

| SQL Server upkeep | Your responsibility | Managed for you | Your responsibility |
| Payroll tax table updates | You install them | Installed and tested for you | You install them |
| Concurrent users | Yes, in the office | Yes, from anywhere | One per office PC |
| Disaster recovery | Your backups | Off-site, tested backups | Your backups |

Ongoing managementThe stakes
The Risks of Running Sage 100 Contractor in the Office
Construction offices often run Sage on whatever server was bought years ago. These are the problems that follow.
Field Teams Working Blind
+
When project managers can’t see current costs, overruns get spotted late and change orders get billed late.
Delayed job cost visibilityOutdated SQL Server and Windows
+
Recent Sage 100 Contractor versions need Windows 10 or Server 2016 or later and a current SQL Server. Older servers block upgrades and miss security patches.
Sage system requirementsPayroll Interruptions
+
A server failure on payroll day is the worst-case scenario for a contractor with crews waiting to be paid.
Payroll continuityRansomware Targeting Contractors
+
Construction firms are frequent ransomware targets because downtime is so costly. Tested off-site backups are the difference between hours and weeks.
Business continuityWhat Hosting Changes
Moving to a managed cloud environment replaces the weakest parts of a local setup:
- Single office server → redundant data center infrastructure
- VPN or open remote desktop → MFA-protected, encrypted sessions
- Forgotten backups → automated, off-site and restore-tested
- Ad-hoc patching → managed Windows, SQL and application updates
- Data on laptops → data that stays on the server
Before you move
Sage 100 Contractor Hosting Checklist
These details shape your hosted setup and your cutover date.
Your Current Setup

- How many companies and years of history? This sets storage and SQL sizing.

- What connects to Sage 100 Contractor? Timecard, field and reporting tools need testing.
Questions for Any Provider
- Who installs payroll tax updates? Updates shouldn’t wait on your schedule.
- Is SQL Server included and maintained? Ask which version and who patches it.
- Can field users print and scan? Plan printing for trailers and remote offices.
- How fast can you restore a company? Ask for a tested recovery time.
