From discovery to implementation

We first review your workflow, existing systems and constraints, then agree the scope and acceptance criteria. A controlled pilot helps validate the approach before wider rollout. Documentation, training and handover form part of the agreed plan. Deliverables, timing and support are confirmed in the proposal.

What determines cost and timing?

Cost and timing depend on feature scope, integrations, data preparation, access controls, security requirements and ongoing support. Third-party licences, cloud usage and maintenance should be identified separately. An initial consultation helps define the assumptions, deliverables and acceptance criteria before proceeding.

Deliverables to confirm before accepting a quotation

Use this checklist to compare proposals and agree the relevant documents, responsibilities and acceptance criteria.

  • Scope and acceptance — List roles, screens, business rules and test scenarios, with clear boundaries for this delivery.
  • Data and integrations — Identify migration, APIs, permissions and third-party constraints, including who provides test access and samples.
  • Source code and handover — Agree code delivery, third-party licences, deployment accounts, operating documents and usage rights.
  • Maintenance and recurring costs — Separate fixes, new features, support hours and cloud, tool and model usage charges.

Planning example

This illustrative scenario explains planning and evaluation. It is not a completed client case study.

For an internal tool replacing Excel quotations, first document pricing rules, approval rights and quotation versions, then pilot with one department. Acceptance tests should cover calculations, permissions, exports and invalid input. Assess AI separately if document understanding is needed.

Frequently asked questions

Should we use an existing tool or commission custom software?
Start by checking whether existing tools meet your core workflow, permissions and integration requirements. Configuration may be enough for standard needs; custom work can address specific gaps.
Does every feature need AI?
No. Clear calculations, permissions and transaction rules generally benefit from predictable software. AI can help interpret unstructured content, with evaluation and human review where appropriate.
Is ongoing maintenance included?
Deployment and ongoing maintenance are different scopes. Updates, monitoring, fixes and support hours should be specified in the agreement.
What should the quotation cover?
The number of user roles, screens, features and approval rules. API connections, data migration and legacy-system constraints. Separate scopes for testing, deployment, documentation and maintenance.
What should we prepare for the initial consultation?
Current workflows, forms and examples with personal information removed. User roles, essential features and systems that must be connected. Budget range, target timing and data-handling constraints.
How do we confirm the deliverables meet our needs?
Agree real user scenarios and expected outcomes before acceptance testing. Compare task duration, errors and review effort for the same workflow. Evaluate AI features using sample cases, incorrect answers and human fallback procedures.
Should we improve an Excel workflow or build custom software?
Improve existing tools first when formatting, formulas or data cleanup address the main problem. Compare custom software when concurrent users, permissions, approval history or cross-system updates become constraints, including ongoing maintenance costs.
How should we compare software development quotations?
Use the same scope and acceptance checklist. Compare migration, API integration, source-code rights, deployment accounts, the defect-fixing period and maintenance. A total price alone can hide differences in scope and third-party fees.
How do we scope internal tools, customer portals and mobile apps?
Start with complete user tasks, permissions, data, interfaces and device capabilities. Compare existing tools, responsive web, PWA and native delivery before defining custom work.
How do UAT and feature changes relate?
Use agreed requirements and expected outcomes to distinguish defects, clarifications and additions. Approve cost, schedule and testing impacts before updating the baseline; business owners accept complete tasks.
