Total software delivery cost: count the work, not the headline figure

OutsourcingVN is operated by Netbase JSC, so we have a commercial interest in the proposals you compare, including our own. This guide gives you a worksheet to apply to every supplier and uses Netbase delivery records to show what drives the length of a bounded scope. It publishes no rates or ranges, because those depend on scope decisions only you and a supplier can make together.

What goes into the total cost of software delivery?

A total is only as good as the request behind it. Give every supplier the same outcome, users, systems, data, integrations, deadline, decision owner and acceptance evidence. The software project brief template gives that request a usable shape.

Then treat every unknown as a named assumption. A supplier may cover an uncertainty in discovery, exclude it or add contingency. Each is legitimate when visible; the problem is an integration, migration or approval cycle that appears in one proposal and is silently implied in another.

Which rows belong in the worksheet?

The last row is the one most often missing. A slow approval or an unavailable subject expert does not disappear because it is absent from a proposal.

What drives the length of a bounded scope?

Duration follows scope, dependencies and acceptance, not the category of project. These are durations registered for specific Netbase scopes; they are records of those scopes, not estimates for yours.

Three patterns stand out. Acceptance testing, handover and a support window appear as named items, not as leftovers. Integrations and migrations are counted item by item, such as the 11 extensions. And ranges widen where the work depends on something unknown at the start, such as the damage found in a compromised store.

Worked example: two proposals that looked different

A distributor asks two suppliers for a B2B ordering portal connected to its ERP. Proposal A's total is noticeably higher than Proposal B's. Mapped to the worksheet, the gap explains itself.

After the three questions, Supplier B revised its proposal to add migration, a test round and a bug-fix window. The two totals moved closer together, and the buyer could finally compare delivery approach instead of guessing at hidden exclusions.

How should the commercial shape be decided?

Most Netbase projects are agreed as fixed-scope contracts after discovery; milestone-based arrangements are also available. Netbase also offers dedicated development teams, on-demand support and fully managed delivery as secondary options. The engagement models guide explains who controls day-to-day priorities in each.

A bounded project moves estimation risk towards the supplier, which is why scope, acceptance and the change route matter. A capacity-led arrangement leaves sequencing with the buyer. A lower first total can be a different allocation of risk rather than less work.

Netbase's delivery lifecycle is discovery and strategic alignment; team assembly and architecture planning; agile execution with outcome-based milestones; modular components; training and rollout; and ongoing support. Project teams draw on business analysis, project management, solution architecture, development, QA and UI/UX roles, and typically range from 3 to 30 people. Check that each proposal staffs the roles its scope needs.

How do distributed delivery and security change the total?

Remote-first delivery adds written handovers, decision records and scheduled overlap to the work. Netbase stays accountable while teams may combine Netbase staff, approved specialists or disclosed partners, and onsite work is available on request and scoped as a separate project activity. The global delivery page describes the model, and the time-zone collaboration guide shows what to agree about overlap and escalation.

Security is an input, not a final checklist. Which environments the team may access, whether data can leave them, how credentials are issued and removed, and who approves a production change all affect effort. The data security and compliance guide lists the questions to settle before access is granted.

Which questions should you ask every supplier?

• What are your assumptions and exclusions? A good answer is a written list you can compare line by line.
• Which rows of the worksheet does your proposal leave to us? Look for named buyer tasks with dates.
• What evidence closes each milestone? Expect a test, a demonstration or a document, and a named signatory.
• How is a change request handled? Expect classification, estimate, approval and a record.
• What is in the handover? Look for documentation, access transfer, training and known limitations.
• What does support cover, and for how long? Expect a written period, scope and exit route.
• Which roles are on the team? Look for analysis, project management, architecture, development, QA and design where the scope needs them.
• How are milestones structured? Look for outcome-based milestones that can be accepted one at a time.

Turn the worksheet into a scoped conversation

Walk the worksheet with your product, finance, security and operations owners, record the unanswered rows and make them a discovery output. Project delivery shows how that output becomes a milestone with inputs and acceptance evidence, and the methodology explains how the records on this page are sourced. For a bounded build, see Custom Product Engineering.

OutsourcingVN is Netbase's own outsourcing-services platform. Submit a project with your outcome, systems, decision owner and constraints, and a person will reply with whether discovery or a bounded delivery scope is the right next step.
