01 · Free first step
Initial inquiry
Describe the problem and identify what needs clarification. Any early budget range is preliminary, not a binding implementation quote.
Pricing
A clear scope. A fixed quote.
No surprise invoices.
Once we agree the deliverables, your implementation price is fixed. If the agreed work takes us longer than expected, we absorb that delivery overrun. Additional requirements are discussed and approved separately.
Know what you are buying
A small first step. A deliberate commitment.
02 · Paid planning, when needed
Reviewed solution proposal
A defined planning deliverable covering requirements, options, the delivery approach, assumptions, and estimates. We agree its price, timing, revisions, and implementation credit before purchase.
03 · Fixed quote for agreed scope
Implementation
A separate agreement with deliverables, acceptance criteria, dependencies, payment milestones, and the implementation price. You decide whether to proceed.
Buying a proposal does not commit you to implementation. Any proposal credit and eligibility conditions are shown before purchase.
A fair allocation of responsibility
We own our delivery estimate.
You should not have to pay more because agreed work took us longer than expected. A clear scope and acceptance criteria make that commitment practical for both sides.
If priorities change, we look for a sensible trade within scope first. Additional work starts only after you approve its price and schedule.
And we keep the project moving together.
We agree together what information, access, and feedback the project needs, and when. If something is delayed, we explain the impact, keep unaffected work moving where possible, and agree revised dates. Any additional work or cost needs your approval.
Review windows, reminders, and any pause or restart arrangements belong in the project agreement. We discuss a delay with you; we do not treat silence as permission to launch.
The whole cost
The build price is only one part of the picture.
Implementation and changes
The quote identifies what is included and excluded, the acceptance criteria, currency and taxes, and payment milestones. Optional phases or features are separate choices.
Running and supporting the solution
Hosting, third-party subscriptions, usage-based services, maintenance, and support are identified separately. Warranty, renewal, and handover terms are agreed before implementation.
Data, licence, and source code
You own your project data. Your working solution and agreed documentation are included, while DVM retains its software intellectual property. Source code is an optional, separately priced handover package, with licence rights to modify the solution, work with other developers, and commercialize it. Your quote explains the source option, applicable third-party licences, hosting, support, and handover before you commit.
