Contractors and energy services firms face a recurring choice: keep accounting and job cost software on a server in the office, or move to a hosted or cloud-based version. Vendors have been steering customers toward the cloud for years, and many make the case well. But the right answer depends on your people, your sites and your risk tolerance. This guide lays out the real trade-offs so you can decide on purpose.
Understand the options
There are really three arrangements, and vendors do not always use the terms consistently.
- On-premises: you own the server and run the software in your building or a data center you manage.
- Hosted: the vendor or a partner runs your existing software on servers in their data center, and you connect remotely.
- Software as a service: a multi-tenant platform built for the cloud, accessed through a browser or app.
Ask your vendor exactly which of these they are offering, because responsibilities differ for each.
Security considerations
What you gain in the cloud
- Professional infrastructure, with physical security, redundant power and monitoring that most small companies cannot match.
- Patching handled by someone whose job is patching.
- Often better built-in backup and disaster recovery.
- Easier secure remote access for field and home users, without exposing your own server to the internet.
What you still own
Moving to the cloud does not remove your responsibilities.
- User accounts, permissions and password practices remain yours.
- Multi-factor authentication must be enabled and enforced.
- Weak controls on payment approvals and vendor changes are not fixed by hosting.
- You need to understand how the vendor protects your data, who can access it and how incidents are reported to you.
What on-premises still offers
- Direct control over where data sits and who touches it.
- No dependence on an outside platform's availability beyond your own network.
- Potentially simpler compliance conversations in some situations, though this is not automatic.
On-premises is only as secure as the care you give it. A server that is rarely patched and reachable by remote desktop is a classic ransomware entry point.
Cost considerations
Compare total cost over several years, not the sticker price.
- On-premises costs: server hardware and replacement cycles, licenses, backup systems, power, IT labor and security tools.
- Cloud costs: recurring subscription or hosting fees, per-user charges, add-on modules and any integration costs.
Include the cost of downtime and the cost of the person who currently keeps the server alive. Ask for a written quote showing all modules and users, since add-ons are a common source of surprise.
Performance and connectivity
Field and office locations matter. A hosted system depends on a reliable internet connection at every location that uses it. If your accounting staff sits in an office with good connectivity, that is easy. If key people work from remote trailers, plan for failover. Large reports and batch processes can behave differently over a remote connection, so ask for a trial with real data.
Integrations and customizations
Spreadsheets, custom reports, bank files and integrations with project platforms may depend on direct database access. Some cloud arrangements restrict that access. List every integration and customization, and ask the vendor how each will work.
Compliance and contracts
If you handle sensitive customer or government information, ask whether a hosted environment is appropriate. For example, defense contractors handling controlled unclassified information need to be careful about where that data resides and what security requirements apply to the provider. Accounting data is not usually CUI, but project documents may be, so keep the distinction in mind.
Review the contract for these points.
- Data ownership and how you export your data
- Uptime commitments and remedies
- Backup frequency and retention
- Breach notification terms
- What happens if you leave, including data return and deletion
A simple decision framework
Score each factor from your own perspective.
- How strong is our in-house or provider IT capability?
- How reliable is connectivity at every location that uses the system?
- How heavily do we rely on customizations and direct database access?
- How sensitive are our uptime needs around payroll and billing?
- What are our budget and replacement cycle for hardware?
- How comfortable are we with the vendor's security answers?
If you lack strong IT support and connectivity is good, the cloud often wins. If you have heavy customization and a capable team, staying on-premises may be reasonable, with stronger security practices.
Whichever you choose
Enforce MFA, review permissions every quarter, test restores and document your plan.
