Investigating cost
How much does custom internal software cost?
The honest answer: it depends on four things—scope, integrations, data quality, and how many different roles the system must serve—and anyone who quotes you a number before understanding those four things in your operation is guessing. We will not insult you with an invented price list. What we can do is explain exactly what moves cost up or down, and how Praxyt arrives at a fixed number you can actually evaluate.
The shape of Praxyt’s answer is this: a Workflow Opportunity Review maps the workflow and what the system must do, and produces a fixed build proposal. You see a real price attached to a real scope before you commit to a build—never an hourly arrangement where the total is discovered afterward.
The four things that drive cost
1. Scope: how many workflows, how many edge cases
One workflow—a quote approval queue, a backorder control tower—is a defined, contained build. Three workflows that share data are a larger one. And within any workflow, the edge cases are where scope lives: standard quotes are easy; customer-specific pricing, credit holds, and margin exceptions are the work. A good scoping process surfaces these early, because an undiscovered edge case is an undiscovered cost.
2. Integrations: what the system must talk to
A standalone tool is one price; a tool that reads and writes to your ERP is another. Modern ERPs with real APIs integrate cleanly. Legacy systems, EDI feeds, and vendor portals each add integration work—and the variance is huge, because it depends on systems you chose a decade ago. This is why integration reality is assessed before any number is proposed.
3. Data quality: what the system inherits
Clean customer and item data makes everything cheaper. If the new system must import fifteen years of inconsistent records, reconcile duplicate customers, or absorb logic buried in spreadsheet formulas, data work becomes a real line item. Nobody can price this from a feature list—it has to be looked at.
4. User roles: how many kinds of people it serves
A tool for one team with one permission level is simple. A system where sales, pricing, warehouse, and management each see different things—and customers see a portal on top—carries design and testing cost per role. Roles are worth it; they are also worth counting.
What makes a project smaller
- One workflow, chosen because it costs the most today.
- One or two integrations, against systems with modern APIs.
- Clean master data, or a deliberate decision to start fresh.
- A small number of user roles with clear boundaries.
- An owner on your side empowered to make decisions quickly.
What makes a project larger
- Multiple workflows bundled into one build because “we might as well.”
- Legacy integration, EDI, or systems with no API at all.
- Historical data migration with real cleanup required.
- Many roles, external users, or customer-facing portals.
- An unsettled process—software hardens whatever process exists, so redesign belongs before the build, not during it.
Common mistakes when budgeting
- Comparing the build to the software subscription and stopping there. The real alternative cost includes workaround labor, errors, and the deals that slow down—see the ROI calculator.
- Accepting hourly billing without a scope. An open-ended arrangement transfers all the risk to you.
- Shopping for the cheapest proposal. Under-scoped proposals are not cheaper; they are later and angrier.
- Padding the first build. A second phase decided with evidence beats a first phase bloated with speculation.
- Forgetting ongoing costs. Hosting and maintenance are modest but real; any honest proposal states them up front.
Frequently asked questions
- Because a published number would be fiction. Two projects with the same feature list can differ by a factor of three depending on integrations, data quality, and how many roles the system must serve. Any firm quoting a price before understanding your workflow is guessing—and you will pay for the guess either way.
- Fixed proposal, after a Workflow Opportunity Review. The review maps the workflow, identifies what the system must do, and produces a scoped build proposal with a fixed price before you commit to anything. You know the cost and the deliverable before the build starts, not after the invoices arrive.
- The review is a structured working session, not a paid consulting engagement. Its purpose is to find out whether a build is justified at all—including the cases where it is not—before either side commits to a project.
- Yes, and we recommend it. Build the one workflow that costs you the most, let it prove itself in daily use, then decide what the second phase is worth with evidence instead of projections. Phasing also keeps each build small, which is the single biggest cost control there is.
- Budget for hosting, maintenance, and refinement. These are modest next to the build—hosting for an internal system is not a large line item—but they are real, and any proposal should state them plainly rather than surprise you in year two.
- Sometimes, over a multi-year horizon. Per-seat pricing across a growing team, plus implementation consulting, plus the hours your people spend on workarounds, can exceed a fixed build cost in a few years. Sometimes the SaaS product is genuinely cheaper. The honest comparison is five-year total cost on both sides, including labor.
