What Is Boostr?
Core Purpose
Boostr is Nimbbl's conversion optimization engine. It determines which payment and offer options are shown to each customer based on real-time eligibility, applies targeted incentives to motivate purchase completion, and surfaces affordable installment plans to reduce price-based abandonment. Boostr works behind the scenes with Sonic (checkout UI) and Orbit (payment processing) to make every checkout more relevant and more likely to convert.
Benefits
For merchants, Boostr delivers measurable outcomes: higher completion rates because customers see only options they can use, more efficient offer spend because targeting limits waste, higher average order values because EMI and subventions make larger purchases accessible, and fewer failed payment attempts because eligibility is validated before options are presented.
Capabilities
Personalisation
Personalisation adjusts the checkout experience for each customer in real time. Boostr validates which payment modes, saved instruments, and delivery options are eligible for the current customer and order, then surfaces only the options that will work. Features include Magik UPI (detecting and surfacing the customer's preferred UPI app), saved cards with per-card EMI and currency options, real-time Pay Later and cardless EMI eligibility, and smart address auto-fill with delivery checks.
The result is a checkout where every option shown is one the customer can complete, which reduces friction and increases the likelihood of payment success.

Incentivisation
Incentivisation gives you an offer engine for creating discounts, cashbacks, and targeted promotions that are evaluated and applied at checkout. You define the offer type (percentage or fixed-amount discount, standard or gamified cashback), set targeting rules by order value, payment mode, card attributes, UPI flow, or product, and configure usage limits to control spend. Boostr evaluates eligibility in real time and shows the customer the best applicable offer before they confirm payment.
Offers drive conversion by giving customers a tangible reason to complete checkout, while targeting and limits ensure your offer budget is spent where it has the most impact.

Affordability
Affordability makes higher-value purchases accessible by surfacing EMI options with accurate pricing and applying subventions that reduce or eliminate interest costs. Boostr discovers eligible EMI schemes for the customer and order, calculates monthly amounts with all fees included, and applies no-cost or low-cost EMI subventions when those programs are configured. Brand EMI subventions are also supported where product brands fund the interest subsidy.
For merchants, affordability converts price-sensitive customers who would otherwise abandon checkout. Customers who see a manageable monthly payment are far more likely to complete a purchase than those facing the full amount upfront.

How Boostr Works with Other Products
Boostr works alongside other Nimbbl products to deliver a seamless checkout experience. Sonic provides the checkout UI that displays the personalized payment options, offers, and EMI plans that Boostr determines for each customer. Orbit handles payment processing and executes the actual payment once the customer selects an option that Boostr has surfaced. Pulse manages routing decisions and takes into account the payment mode and partner path that Boostr's eligibility checks have identified as available for the customer. Together, Boostr decides what to show, Sonic presents it, Pulse routes it, and Orbit processes it.
