Subscription app for bookstores and publishers

Subscriptions, recommendations and release notifications

Subscription model and personalization. The app learns preferences, recommends series/authors, reminds about releases and makes repeat purchases easier. Before work starts, we agree the scope and the measures that will show whether it works for your business.

01What is not working todayDropping retention and one-off purchasesThe situation that costs the team time, sales or control of the process.

Bookstores and publishers fight for recurring purchases. Promotions alone are not enough - you need a product that builds habit.

  1. 01One-off purchases and low customer lifetime value
  2. 02Lack of personalization and recommendations
  3. 03Hard to communicate releases and preorders
  4. 04High customer acquisition cost
02How the solution could workSubscriptions and recommendations that drive retentionThe key parts of the system and the role each one plays in daily work.

Subscription model and personalization. The app learns preferences, recommends series/authors, reminds about releases and makes repeat purchases easier.

  1. 01Subscriptions (monthly boxes / credits)
  2. 02Personalized recommendations (collaborative filtering)
  3. 03Wishlists and followed series/authors
  4. 04Push notifications for releases and price drops
  5. 05Fast payments and 1-click reorder
03What our work provesExperience from a related areaSee what a related delivery proves and what should not be inferred from it.

This project demonstrates experience in a related area. We do not present it as proof that we delivered this exact scenario.

04What to measureWhat we will validate in your businessThe metrics to define before work starts and review after a pilot.

These are areas to measure, not promised outcomes. We will agree the baseline and target before work starts.

01

Metric to validate

Higher customer lifetime value

We will establish a baseline for higher customer lifetime value and measure the change using pilot data before treating it as an outcome.

02

Metric to validate

Retention

We will establish a baseline for retention and measure the change using pilot data before treating it as an outcome.

03

Metric to validate

Lower acquisition cost

We will establish a baseline for lower acquisition cost and measure the change using pilot data before treating it as an outcome.

05How we define the scopeFrom the problem to an agreed planFrom a clear problem to an agreed scope, price and delivery plan.
01

Define the problem

We examine the process, users, data and constraints, then agree which problem is worth solving first.

02

Map and test the flow

We design the key product journey and test it with the people who will actually use it.

03

Build and integrate

We build the product, integrations and tests together. Progress and decisions stay visible throughout.

04

Launch and measure

We release in stages, measure the agreed indicators and use the evidence to plan what comes next.

06What needs to connectSystems and integrations behind the solutionThe systems, data and integrations required for a safe launch.
