Business-Transforming Innovations: How Companies Are Implementing Pay-as-You-Go and Subscription Models

Business innovation has already transformed subscription revenue from an “IT experiment” into a market worth $492.34 billion in 2024 —a 435% increase over the past decade. Subscription-based companies generate 3–5 times more revenue per customer over the customer lifecycle compared to traditional one-time purchase models. This article compiles practical scenarios on how to launch a subscription and installment payment plan in a way that removes price barriers, stabilizes cash flow, and avoids disrupting operational processes.

What Are Pay-as-You-Go and Subscription Models?

Installment payments are a financial arrangement in which a customer divides the total cost of a purchase into installments and pays them according to a schedule over a fixed period. For businesses, this is a way to close a deal without causing “price shock” for the buyer, while still receiving payment guarantees.

A subscription is a business model in which a customer pays regularly for access to a product or service, and the company generates predictable revenue from recurring payments. This model works best in niches where the product is used continuously or where customers return to it regularly: from video streaming and music to cloud services and professional education.

From a technical standpoint, the subscription business model is implemented through various monetization formats:

1. A SaaS subscription is a standard monthly or annual payment for access to software (CRM, accounting, analytics).
2. Freemium — the basic version of the product is provided for free, while advanced features are unlocked with a paid subscription. This lowers the barrier to entry and allows you to sell value after users have tested the product.
3. A product subscription is the regular delivery of physical goods or the provision of a service for a fixed fee, where convenience plays a key role, outweighing the desire to save money on one-time purchases.

Once this distinction is made, it becomes clear which option to launch first. A subscription model is a “long-term” strategy that boosts customer retention, while pay-as-you-go provides immediate results by increasing conversion rates specifically on high-value orders.

Recurring payments form the technical foundation for subscriptions. Payment providers, such as Fondy, define them as “no-acceptance” payments: the customer enters their card details once, agrees to the terms, and subsequent charges are processed automatically without their involvement. This tool has become the standard for businesses where service continuity is critical.

However, recurring payments solve only part of the problem. There is a separate category of situations where a customer wants to receive a product right away but isn’t ready to pay the full amount at once. This is the business pain point we address at eDilo. Our service allows customers to split payments into installments, which is critically important for the B2B sector and high-value purchases where a traditional subscription model isn’t feasible.

How Pay-as-You-Go and Subscription Models Work in Business

The subscription-based business model changes the very essence of sales: the company isn’t selling a “box” of goods, but rather access over time. As long as the customer sees value, they’ll keep paying. But to prevent this process from turning into chaos with manual invoicing, you need a clear system of pricing, billing, and renewal rules.

The process for starting a subscription usually goes like this:

1. Defining the core value proposition. The team determines exactly what the customer is paying for every 30 days. This could be access to a knowledge base, usage limits for the service, or regular content.
2. Creating a pricing matrix. Develop 2–4 distinct plans with clear differences.
3. Billing settings. Businesses can choose between a “payment calendar” (where the schedule is stored on the payment gateway’s side) and API integration (where the logic is managed within the product). Fondy notes that security is key here. Card data is stored in encrypted form on the provider’s side.
4. Launch churn management. Set up automatic reminders, scenarios for failed charges, and customer win-back tools, as well as a transparent unsubscribe process to avoid negative experiences.

Installment payments work differently. In this case, the company sells the same product as before but changes the financial structure to make it easier for the customer to agree to the deal. In the B2B segment, this approach often becomes the deciding factor in closing deals for equipment, transportation, or medical solutions—where the purchase price is objectively high.

The process for implementing phased payment consists of the following steps:

1. Analysis of product categories. The minimum purchase amount is determined—the point at which the total amount will actually influence the purchase decision.
2. Establishing the terms. The deadlines, payment schedule, and rules for the initial payment are set.
3. Integration of a ready-made solution. The business connects to the service (for example, eDilo) and integrates it into all sales channels: the website, sales proposals, and sales scripts.
4. Sales Department Training. Managers learn to present installment payments not as a concession or discount, but as a convenient financial tool.

In this process, our eDilo service addresses a key need: the buyer is able to pay in convenient installments, while the seller maintains the original price and the speed of the transaction. This approach is particularly effective when a customer isn’t asking for a “lower price” but is looking for a way to “pay differently.”

Pros and Cons of Pay-as-You-Go and Subscription Models

Subscription revenue provides businesses with a stable stream of payments and deep customer loyalty, as the product becomes part of the customer’s daily routine. Market experts, including Tranzzo, cite the subscription model as one of the major trends in e-commerce precisely because of the predictability of revenue and the opportunity to build long-term relationships with the audience.

Paying in installments gives businesses another important advantage—it shifts the customer’s focus from the total cost to the size of the monthly payment. This removes the psychological barrier of “it’s too expensive right now.” If a company sells expensive equipment or comprehensive services, this tool often saves a deal that might otherwise fall through.

However, it’s important to assess the risks objectively, as these models do not tolerate errors in the processes. According to Fondy, up to 20% of churn in subscription-based businesses occurs not because the customer wants to leave, but due to technical glitches: they forgot to top up their card, or the transaction was declined by the bank. This means that subscription services require high-quality automation and customized scenarios for retry attempts.

To make it easier to analyze, we’ve summarized the main pros and cons in a table:

The benefits for the business become apparent in the financial statements (P&L) as early as the first quarter. Subscriptions smooth out seasonal fluctuations in revenue, and recurring payments minimize the human factor in the payment process. Paying in installments, in turn, speeds up decision-making on high-cost items. The sales team has to negotiate less, as the conversation shifts from “give me a discount” to “choose a payment plan that works for you.”

Are Installment Payment Models Beneficial for Businesses and Customers?

The answer is clear: yes. A subscription guarantees stability through recurring payments, and paying in installments significantly increases conversion rates on large transactions without forcing businesses to undercut prices. The benefit for the customer is also clear: it’s an opportunity to free up budget and launch a project or purchase an asset without waiting for the “perfect moment.”

Business Benefits: The Numbers That Matter

Subscription revenue forces a company to think about the long-term economics, and this is where systematic profit is generated. LTV (Lifetime Value)—the lifetime value of a customer—becomes the key metric. It is often calculated as the average revenue over a period divided by the churn rate. For example, with an average monthly spend of 1,000 UAH and a churn rate of 5%, the LTV would be 20,000 UAH. This allows for a radical shift in the approach to marketing budgets.

Paying in installments yields quick results. As analysts at MC.today note, implementing tools such as “pay in installments” in retail can boost sales by 35–40%. Even if these figures may differ in the B2B sector, the underlying mechanism remains the same: businesses don’t lose a client at the final stage of negotiations due to a lack of funds “right here and now.”

An added bonus is automation. The payment provider can automatically retry charge attempts after a failed transaction and send reminders. This saves managers time and maintains a steady revenue stream without the need to manually “chase down” every payment.

Benefits for customers: affordability and budget control

Paying in installments gives the customer what matters most—control. Instead of a single large payment that can throw you off track, you get a clear payment schedule. Banking products, such as PrivatBank’s “Instant Installment Plan for Business,” offer terms of up to 24 months, allowing customers to comfortably spread out their financial burden.

Subscriptions are a win because of their convenience. Customers don’t risk losing access to an important service because they forgot to pay a bill, since the system works automatically. This also eliminates the risk of errors that can occur when entering payment details manually.

eDilo Case Studies: High-Value Transactions Without Discounts

The effectiveness of installment payments is best illustrated by real-world transactions where a lump-sum payment would be problematic:

1. Logistics. The Kyiv Carriage Works signed a contract worth approximately 2,000,000 UAH. The buyer, PP “Fishka Nov,” purchased two railcars, paying the amount in installments over 6 months via eDilo. Without this tool, the deal might not have gone through due to the high barrier to entry.
2. Sports and Tourism. Veliki.ua sold a batch of 8 electric bicycles to “Infocenter Karpaty” for approximately 360,000 UAH. The client used a payment plan to launch the rental service. This is a classic example of how a purchase becomes an investment. The equipment starts paying for itself right away, while payments are spread out over time.
3. Manufacturing. INSORTEX sold an industrial crusher worth 360,797 UAH to a sole proprietor. For small agribusinesses, this is an opportunity to scale up without cash flow gaps.
4. Medicine. One of the most telling examples is the sale of the “Vi One” medical device, valued at approximately 1,896,300 UAH. The clinic received the equipment on a 12-month installment plan, which allowed it to immediately begin providing new services to patients.

A business that ignores flexible payment models risks being left behind, where every transaction requires a Herculean effort to overcome the price barrier. Ultimately, stable revenue goes to those who make the purchasing process seamless and the product’s value indispensable.
