Every great business innovation starts as a diagram on a whiteboard. Lines and boxes connect ideas, map out customer journeys, and define complex operational processes. But translating that elegant diagram into a living, breathing, and scalable business function is where the real challenge begins. Manual processes are brittle, custom-coded monoliths are difficult to change, and workflows often remain siloed and inefficient.
What if you could capture the logic from that whiteboard and turn it directly into a robust, versioned, and instantly deployable software component?
This is the core promise of Services-as-Software, a paradigm that transforms how we build and run business operations. With service.do, you can define any business capability as code, deploy it as a simple API, and deliver value on-demand. It's time to move from complex diagrams to executable workflows.
Let's break down this powerful concept. Services-as-Software is the practice of encapsulating a specific business function—like 'process a payment,' 'onboard a new customer,' or 'generate a quarterly report'—into a self-contained, deployable software component.
Think of it like this: your business process is a recipe. Traditionally, you'd have to follow that recipe manually every time, or build a whole custom kitchen just to make that one dish. With Services-as-Software, you package that recipe into a smart appliance. Now, anyone who needs that dish can just press a button (make an API call) and get a perfect, consistent result every time, without needing to know anything about the kitchen (the underlying infrastructure).
This approach allows you to version, scale, and reuse your core business logic just like any other piece of modern software.
The service.do platform is built around a simple, powerful mantra: Define. Deploy. Deliver. It provides the tools and infrastructure to embrace Business-as-Code without the operational overhead.
It all starts with defining your service's logic in a clear, readable format. Instead of clunky visual builders or restrictive configuration files, you write simple code that represents your business process. This is Business-as-Code.
Using TypeScript, you can define the precise inputs and outputs of your service, ensuring a strong contract for anyone who uses it. The business logic itself lives inside an async run function.
Here’s a look at a Customer Onboarding service defined on service.do:
import { Service, type Context } from '@do/sdk';
// Define the input and output schemas for your service
interface OnboardingInput {
name: string;
email: string;
plan: 'free' | 'pro' | 'enterprise';
}
interface OnboardingOutput {
customerId: string;
welcomeEmailSent: boolean;
status: 'complete' | 'failed';
}
// Create a new Service instance with your business logic
export default new Service<OnboardingInput, OnboardingOutput>({
name: 'customer-onboarding',
description: 'Onboards a new customer, creating an account and sending a welcome email.',
async run(input: OnboardingInput, context: Context): Promise<OnboardingOutput> {
console.log(`Starting onboarding for ${input.email} on plan ${input.plan}`);
// Business logic goes here.
// e.g., call user.create, email.send, billing.setup agents
const customerId = `cust_${context.invocationId}`;
return {
customerId,
welcomeEmailSent: true,
status: 'complete',
};
},
});
The beauty of this approach is its clarity. Any developer or technical stakeholder can read this file and understand exactly what the service does, what it needs, and what it produces.
Once your service is defined, what about servers, scaling, and security? You don't have to worry about them.
The service.do platform is fully serverless. You simply commit your code, and we handle the rest:
You get to focus entirely on the business value your service provides, not the plumbing required to run it.
Your deployed service is now a powerful, reusable asset, delivered as a simple API. Any authorized application, team, or even partner can now execute your complex "Customer Onboarding" workflow with a single, straightforward API call.
This turns your operations into composable building blocks. Need to onboard a user from your mobile app? Call the API. Need to bulk-onboard users from a CRM import? Call the same API. Your business logic is centralized, consistent, and easy to integrate everywhere.
If you're familiar with microservices, you might see some parallels. Both focus on breaking down large systems into smaller, independent components. However, .do Services are purpose-built for a specific, powerful pattern: agentic workflows.
A .do Service is designed to be an orchestrator. Its primary job is to coordinate other agents and services to complete a complex business task. In our customer-onboarding example, the service itself might not contain the logic to create a user in a database or send an email. Instead, it would make calls to other specialized agents:
This creates a highly modular and resilient system. If you need to change your email provider, you only update the email.send agent; the customer-onboarding service logic remains untouched. This orchestration-first design, combined with the serverless "Business-as-Code" approach, is what makes service.do unique.
You can model almost any business process you can imagine. If you can describe it as a series of steps, you can build it as a service. Our customers are building:
The possibilities are limited only by the processes you want to automate and scale.
Stop leaving your core business logic trapped in spreadsheets, confusing diagrams, and monolithic codebases. By embracing Business-as-Code with service.do, you can transform your operations into scalable, versioned, and reusable software assets.
