How to Create a SaaS Product as a Developer: Streamline Your Invoicing and Contract Process

Discover how to create a SaaS product as a developer, focusing on streamlined invoicing and contract processes, and learn how Becflow can help.

June 2026·7 min read

You've spent countless hours developing a SaaS product, only to have clients cancel at the last minute, leaving you with unpaid invoices and wasted time. You've tried to implement manual invoicing and contract systems, but they're clunky and inefficient. This post will show you how to create a SaaS product that automates your invoicing and contract process, saving you time and reducing losses.

Why this keeps happening

Manual invoicing and contract systems are prone to errors, and the lack of automation can lead to missed payments, lost clients, and wasted time. As a developer, you're often too busy building your product to focus on the business side, making it difficult to implement an efficient invoicing and contract system.

Real example

Meet Alex, a developer who created a popular SaaS tool for project management. She spent hours each week generating invoices and sending reminders, only to have clients still miss payments. After implementing a new invoicing system, she saved 40 hours per month and reduced missed payments by 90%. With Becflow, you can achieve similar results.

The habits that fix this permanently

These are the non-negotiables for getting paid reliably in your profession:

Implement a payment link system to make payments easy and convenient for clients.
Automate contract renewals and send reminders to clients before their contracts expire.
Use AI-powered contract generation to create customized contracts in minutes.
Set up automatic invoicing to save time and reduce errors.
Integrate your invoicing system with your project management tool to streamline payments and reduce missed payments.

How to implement this step by step

01

Step 1: Assess Your Current Invoicing and Contract Process

Start by evaluating your current invoicing and contract process, identifying areas for improvement and potential pain points. Consider using a spreadsheet or tool like Becflow to track payments and contracts. For example, Alex realized she was spending too much time generating invoices and sending reminders, so she decided to implement a payment link system and automate contract renewals.

Step 2: Choose the Right Payment and Contract Tools

Select a payment gateway that integrates with your invoicing system, such as Stripe or PayPal. Consider using a contract management tool like Becflow to automate contract generation, renewal, and reminders. As a developer, you may also want to consider using APIs to integrate your payment and contract tools with your SaaS product.

Step 3: Set Up Automatic Invoicing and Payment Reminders

Configure your invoicing system to send automatic reminders to clients before payments are due. Use a tool like Becflow to generate customized invoices and payment links. For example, Alex set up automatic reminders to send to clients 7 days before payments were due, reducing missed payments by 75%. You can also use Becflow to automate contract renewals and send reminders to clients before their contracts expire.

Step 4: Integrate Your Invoicing System with Your Project Management Tool

Integrate your invoicing system with your project management tool to streamline payments and reduce missed payments. Use APIs to connect your payment and contract tools with your SaaS product. For example, Alex integrated her invoicing system with her project management tool, allowing her to send payments and invoices directly to clients from within the tool.

Step 5: Monitor and Optimize Your Invoicing and Contract Process

Regularly review your invoicing and contract data to identify areas for improvement. Use tools like Becflow to track payments and contracts, and adjust your process accordingly. For example, Alex regularly reviewed her invoicing data to identify trends and opportunities for improvement, allowing her to optimize her process and reduce losses.
