Migration · Sage 100 Contractor to ServiceTitan
This pair is different from the others on this page, and the difference matters more than any technical detail: these two systems do substantially different jobs. Sage 100 Contractor is a construction accounting and job costing system. ServiceTitan is a service operations platform. One is not a newer version of the other.
Which means the honest version of this engagement usually is not a migration at all — it is a split. The service operation moves to ServiceTitan; the accounting and job costing stay somewhere that does accounting. Anyone quoting you a straight replacement has not understood what you currently run.
Sage 100 Contractor holds accounting, job costing, payroll, and service management together, and extraction can reach all of it. ServiceTitan is a service operations platform with a defined intake that expects service-shaped data. The gap is not access — it is that a large portion of what Sage holds has no corresponding object in the destination. The assessment's primary job on this pair is telling you precisely which of your data has a home and which does not, so the decision you make is informed.
Each of these gets its own record count in the assessment and its own line in the reconciliation report. Depth of history is a scope decision made with real numbers in front of you, not an assumption baked into a quote.
Customers and service locations
Customer records split into customers and service locations as ServiceTitan expects them, derived from the Sage customer and job structure.
Service history
Historical service calls with dates, technicians, and work performed, where the service management side of Sage was actually used.
Equipment at location
Installed equipment attached to the correct location, recoverable where recorded and reconstructed with clear labelling where it exists only in service notes.
Service agreements
Agreement terms, covered equipment, billing schedules, and renewal dates, reconciled as their own step.
Open receivables
Current customer balances — with an explicit decision about whether ServiceTitan or the retained accounting system is authoritative going forward.
Price book and cost data
Service items and materials mapped into ServiceTitan's price book structure, informed by Sage cost data where it is usable.
Technicians
Technician records including inactive technicians whose historical work must stay attributed.
Written down before you spend anything, because the alternative is finding out in week six. This list is specific to Sage 100 Contractor to ServiceTitan; the assessment turns it into your list, with record counts attached.
— Job costing. This is the headline and it deserves to be stated plainly: ServiceTitan is not a construction job costing system. Committed costs, cost codes, and job-to-date detail have no destination, and if job costing is central to your business, the answer is that you keep an accounting system rather than that you migrate it.
— The general ledger, accounts payable, and financial statements. These stay in an accounting system — Sage, retained, or a replacement chosen deliberately.
— Payroll, including certified payroll and prevailing wage reporting. Out of scope for a service platform and needs its own home.
— Subcontractor management, lien waiver tracking, and compliance documentation. Construction-side objects with no service-platform equivalent.
— Progress billing, AIA-style billing, and retainage. Service billing and construction billing are different problems.
— Sage internal record IDs. ServiceTitan issues its own; anything keyed externally needs the mapping table.
None of this is in either vendor's documentation. It is the category of thing that looks fine in a test load and produces a wrong number in month two, which is why the process puts a full sandbox load and a reconciliation you sign in front of any production cutover.
01
The assessment on this pair frequently concludes that you should run both — ServiceTitan for service operations, an accounting system for the books — with a defined integration between them. That is a genuinely good outcome and it is worth paying for the clarity, even though it is not the answer people expect when they start.
02
Contractors running Sage often manage service informally, in a module they use lightly or alongside paper. If that is the case, there is less service history to migrate than expected — which lowers the migration cost and raises the amount of structure that has to be built new.
03
If accounting stays in Sage and operations move to ServiceTitan, invoices exist in both. Which system is the source of truth for each object has to be decided during mapping and enforced by the integration afterwards, or the two drift apart within a quarter.
04
Many contractors run both. If yours does, the cleanest structure is usually to stop pretending one system should serve both — and that reframing, more than any field mapping, is what makes the engagement worth its price.
01 — 02
A read-only audit of your Sage 100 Contractor instance produces record counts, a risk register, and a fixed quote. Then a field-by-field mapping document you sign before any code runs.
03 — 04
The complete migration runs into a ServiceTitan sandbox — not a sample. You spot-check records you choose, and sign a written reconciliation. If the counts don't tie, we don't cut over.
05 — 06
Scheduled around your calendar with the rollback plan written in advance, followed by 30 days of included corrections for the things that only surface in real use.
Complex in essentially every case, because the engagement includes a systems-architecture decision and usually an integration design alongside the migration itself. The assessment is what makes a fixed migration price possible, and its fee is credited toward the migration if you proceed.

For a pure service business with no construction work and simple accounting needs, possibly, paired with a standard accounting package. For a contractor doing project work with job costing, certified payroll, or progress billing, no — and I would say so during the assessment rather than after you had paid for a migration that leaves half your operation homeless.
It stays in an accounting system. There is no version of this migration where job costing lands in ServiceTitan, and any proposal implying otherwise is worth questioning closely. The realistic outcome is ServiceTitan for service, Sage or a replacement for the books, integrated deliberately.
First, clarity — a written account of which of your data has a home in ServiceTitan and which does not, which is the thing nobody will give you before you have signed. Second, the migration of the service side. Third, the design of the boundary between the two systems, which is what determines whether this works in a year.
Particularly then. On this pair the assessment frequently changes the plan, and finding out that you need a split architecture rather than a replacement is worth considerably more than the assessment costs. You own the report regardless.
The assessment is the read-only audit — what data exists, what is extractable, what will be lost, and a fixed-price quote for the migration itself. It is priced at $1,500 – $2,500 depending on scope, fixed before anything starts, and the report is yours whether or not you go further.

Nothing is committed by this form. No payment, no contract, no scheduling sequence. It starts a conversation.
If your destination vendor can handle it, I'll say so. Some conversions genuinely don't need an independent migration.

The most expensive mistake in this category is losing source-system access before the extraction is done. The assessment is read-only, fixed-price, and yours to keep either way.
