What vendors need to estimate an iGaming build

What is the minimum useful estimate brief?

The minimum useful brief defines the business decision, product boundary, intended markets, delivery responsibilities, external systems, evidence requirements, timeline constraints, and acceptance method. It also separates confirmed facts from assumptions and open questions.

Ask vendors to return a range, confidence level, exclusions, dependencies, and the assumptions that move the range. A single number without those records is difficult to compare or govern.

Which product decisions change the estimate?

Describe the users, product type, core journeys, devices, languages, accessibility expectations, content volume, administration needs, reporting, and launch definition. For a game, include the rules, mathematics state, art and audio scope, client and server boundaries, and integration route. For a platform, include accounts, wallet, content, payments, identity, reporting, back office, and data migration.

Prioritize requirements as required for launch, planned later, optional, or explicitly excluded. This prevents every idea from being priced as an immediate dependency.

Which market information is necessary?

Name each intended jurisdiction and the assumed entity, license, product, and supplier roles. Provide known technical standards, testing path, language, currency, payments, identity, reporting, hosting, data, and responsible-gambling requirements.

If those decisions are not confirmed, ask for a paid discovery or separate assumption range. Do not ask a development estimate to stand in for qualified legal or regulatory advice. The United States market hub and Latin America market hub show why broad regions are not sufficient scope.

Which integrations need interface evidence?

For every external system, provide the owner, documentation, sandbox status, authentication method, data flow, rate or availability constraints, required events, error behavior, and contact path. Mark whether the vendor must only integrate, also procure, or operate the service after launch.

Unknown or unavailable interfaces should appear as explicit discovery items, not as invisible fixed-price assumptions.

Which delivery responsibilities belong in the request?

Area	Questions to answer before comparison
Product	Who owns priorities, decisions, content, and acceptance?
Design	What exists, which devices matter, and who approves the system?
Engineering	Who owns architecture, repositories, environments, reviews, and releases?
Quality	Who defines coverage, prepares data, fixes defects, and signs off?
Testing readiness	Which standards, laboratory, evidence, and submission tasks are assumed?
Operations	Who monitors, supports, restores, patches, and responds to incidents?
Handover	Which code, data, accounts, documents, licenses, and training must transfer?

What timeline evidence should the vendor receive?

Provide the real deadline, its business reason, fixed external dates, approval windows, internal availability, and dependencies. Ask the vendor to show discovery, design, implementation, integration, evidence preparation, external review, contingency, and launch support separately.

A requested launch date is not evidence that the scope fits. Require each proposal to state the staffing and decisions needed to make its schedule plausible.

How should proposals be normalized?

Give every bidder the same versioned question set and allow written clarifications visible to all participating bidders. Normalize price by scope, assumptions, taxes, licenses, third-party costs, internal work, support, change control, and exit obligations.

Use the development-partner framework to evaluate evidence after the estimates arrive. If Wizards may fit, its game-development services can be evaluated through the same process; Wizards operates GEN.
