Build the revenue model into your app.

Subscriptions, advertising and marketplace commissions need more than a payment button. We help founders turn a pricing model into reliable access, payment, refund and reporting workflows.

Start with who pays, and why.

A subscriber pays for recurring value. A marketplace seller pays for a completed transaction or a service. An advertiser pays for eligible exposure or outcomes. We map the payer, value delivered and payment event before estimating the software.

This service suits a founder validating an app concept, a team adding paid tiers to an existing product or a marketplace improving commissions and reconciliation. Share the product stage and commercial assumptions so we can define a focused first release.

What we can build

01

Subscriptions & access

Plan entitlements, trials where appropriate, renewals, cancellations and restore-purchase journeys. Connect verified purchase events to backend access instead of trusting a client-side success screen.

02

Advertising integration

Integrate an agreed ad provider, placement rules and consent flows appropriate to your audience. Define where ads should not interrupt a task and measure the effect on retention.

03

Marketplace commissions

Model seller earnings, platform fees, refunds and payment-provider settlement. Give operations a reconciled record of what was collected, retained and paid out.

04

Paid features & upgrades

Design understandable feature limits and upgrade journeys. Keep pricing, access and cancellation information visible so customers know what their payment changes.

05

Payment reliability

Handle verified webhooks, duplicate events, retries, failed payments and refund updates. Agree supported providers, currencies and distribution markets before implementation.

06

Revenue reporting

Connect purchase, renewal, refund and usage events to an agreed reporting plan. Separate gross transaction value, recognised platform revenue and actual cash settlement.

From assumptions to a tested release

  1. Discovery: define audience, payer, product type, countries, platforms and existing systems. Record what is known and what still needs validation.
  2. Economics: compare revenue assumptions with provider charges, support, infrastructure and acquisition costs. Agree the primary revenue model and reporting definitions.
  3. Scope and design: specify screens, entitlements, payment events, admin controls and exception handling. Separate launch essentials from later experiments.
  4. Implementation and QA: test purchase, renewal, cancellation, restore, failed payment, duplicate notification and refund journeys in supported test environments.
  5. Release and measurement: prepare the agreed release, documentation and event tracking. Review actual conversion and retention before extending the product.

Deliverables agreed upfront

  • Revenue-flow specification and user journeys
  • Agreed app, backend and admin implementation
  • Payment-state and entitlement rules
  • QA evidence for scoped lifecycle scenarios
  • Integration notes and operational handover

What affects the estimate?

Platforms, existing code quality, billing providers, currencies, seller payouts, reporting depth and migration needs affect scope. We quote after reviewing these inputs.

Provider fees, advertising spend, store accounts and third-party subscriptions are separate unless explicitly included. Customer demand, income, app-store acceptance and ad yield cannot be guaranteed by a development project.

Choose payment flows for your product and market.

Digital content, physical goods and real-world services can have different store payment requirements. The implementation must account for distribution platform, region and programme eligibility. We review the relevant current documentation during scoping.

If you plan to hold customer funds, offer regulated financial products or run prize-based schemes, specialist legal and payment-provider review is a separate requirement to establish before a build scope is agreed.

Questions founders ask

Can you add monetisation to an existing app?

Yes, subject to reviewing its code, architecture, release setup and provider accounts. We scope the integration and any migration before committing to an implementation plan.

Which model will earn the most?

That depends on willingness to pay, retention, usage and costs. We can help compare scenarios and implement measurement; reliable conclusions require data from your product.

Can one app combine subscriptions and ads?

Yes. The access rules should define whether subscribers see ads and what happens when a subscription expires. Model the revenue streams without counting ad impressions from users who do not see them.

Do you provide users or guaranteed income?

No. This is software development and integration support. Acquisition campaigns and commercial targets need a separate plan and budget.
