Technology & SaaS app development cost

It depends far more on scope than on the sector, and quoting a single figure here would be the least useful thing this page could do. What technology & saas does decide is the floor: 5 compliance regimes may apply, you will be asked to integrate with roughly 7 systems of record, and 6 distinct roles typically touch the workflow — all of that before a single feature. The calculator below is already set to this sector; answer the rest and it returns a cost range, hours, timeline, team and running costs for your own scope.

Typically $30,000–$70,000 over the equivalent single-tenant product, and considerably more if you retrofit it. The cost is not a tenant column on your tables — it is that every query, cache key, background job, export and test must be tenant-aware, and that a single missed filter is a data breach rather than a bug. That raises your security and QA bar permanently. Design for it from the start even if you launch with one customer.

When a deal depends on it, not before — but design so you can. SAML SSO, SCIM provisioning, audit logs and role granularity total $80,000–$180,000 of engineering, and SOC 2 Type II adds $20,000–$45,000 in auditor fees on top of the evidence work. Building it speculatively is premature. Building your auth layer and data model so it can be added without a rewrite costs almost nothing and saves a painful quarter later.

It is a planning estimate, not a quote. The band shown is roughly plus or minus 15–20% for a well-defined scope, and wider while requirements are still moving. It is built from engineering hours per discipline, converted at our blended delivery rate, so the hours are directly comparable to a real proposal line by line — but a firm price needs a technical specification, which is the step after budgeting.

No, deliberately. The headline figure is one-off development cost. Monthly cloud infrastructure, metered vendor fees and annual maintenance are calculated separately and shown alongside it, because they are recurring operating costs rather than capital build cost. Adding them together produces a number that means nothing.
