How to screen custom software development opportunities
Compare federal custom programming opportunities by the application, users and deliverables. New development, modernisation and modifications to an existing system require different discovery work and technical evidence.
- Identify the required functions, integrations, data sources and acceptance criteria.
- Check the existing stack, source-code access and responsibility for third-party components.
- Review the required security, accessibility, testing and documentation deliverables in the official scope.
- Confirm deployment, training, maintenance and ownership terms before proposing a delivery model.
Use the buyer-assigned classification for discovery, then verify the complete scope, eligibility and current amendments in the official notice. Related requirements may be advertised under other classifications.
Build your estimate before you bid
- Estimate discovery, development, migration, integration, testing and deployment separately.
- Allow for review cycles, environments, licences, documentation and any support period included in the scope.
Is ongoing support included in a development contract?
Check the deliverables and option periods. A development price may also need to cover defect correction, hosting, user support or maintenance; do not assume these are separate purchases.
Use the bid / no-bid checklist · Plan your response milestones
Software contract example: turn features into acceptance evidence
GovBidFit planning example · Illustrative assumptions, not a live solicitation or market price.
Imagine a hypothetical application with three user roles, two external integrations and a migration from an existing database. A feature list alone misses the work required to prove permissions, handle integration failures and reconcile migrated records.
- Create a deliverable map for each role and workflow. Describe what the user must be able to do and what observable test would demonstrate that it works.
- For each integration, record the interface owner, test access, data format, failure behavior and ongoing dependencies. Flag any access you need from the buyer before committing to a schedule.
- Plan a trial migration with source counts, rejected-record handling, reconciliation and sign-off. Separate development, acceptance testing, deployment, documentation and any required support period.
Use the solicitation to establish the required security, accessibility and deployment conditions. Identify whether source-code handover, licensing, hosting and ongoing support belong in the response. List unresolved dependencies as questions rather than quietly assuming the buyer will provide everything on day one.
How do I assess a federal software development bid?
Compare the requested outcomes with your team's delivery evidence, integration access and test capacity. A short feature list can still require substantial migration and acceptance work; map those obligations before committing to a delivery date.
