Invoicing is essential for every business, yet most still rely on slow, manual processes that waste time, delay payments, and create compliance risks. For SMEs, this isn’t just frustrating—it directly impacts cash flow and growth.

But invoicing doesn’t have to be a bottleneck. With the right e-invoicing API, you can automate the entire process, ensure compliance, and even turn invoicing into a revenue stream for your business. Here’s how to do it fast and effectively.

Who Are SME’s

SMEs (Small and Medium-sized Enterprises) are businesses that fall within a certain size range based on employee count, revenue, or assets. The exact definition varies by country and industry, but they are crucial to economies worldwide because they drive innovation, create jobs, and contribute significantly to GDP. They often face challenges like limited funding, regulatory complexities, and competition from larger businesses.

In Dubai and the UAE, SMEs make up the majority of businesses and are heavily supported through government initiatives, funding programs, and incentives, especially in sectors like tech, trade, and services.

 

 

Problem With Invoicing

Every business has to invoice, yet most companies worldwide still do it manually. The problem? Manual invoicing is time-consuming and costly. Beyond that, invoices must be issued, delivered, checked, and then paid—whenever the recipient decides to do so.

Adding to the complexity, ever-changing regulations increase the likelihood of mistakes, fines, and wasted time trying to stay compliant. To address this, governments worldwide are gradually introducing mandatory e-invoicing. While the initial integration costs can be high, e-invoicing streamlines invoicing processes and significantly reduces long-term costs for SMEs. For governments, it also drastically reduces the risk of fraud in business transactions.

For companies, however, implementing e-invoicing presents a challenge. They either need to build an in-house solution, which is extremely expensive and takes at least a year, or integrate a third-party provider—but finding the right invoicing API can be difficult.

 

 

E-invoicing As Solution

E-invoicing (electronic invoicing) is the process of sending, receiving, and processing invoices electronically in a structured digital format. Unlike traditional paper or PDF invoices, e-invoices are created, transmitted, and stored using standardized data formats like XML or EDI (Electronic Data Interchange).

The key difference is that e-invoices are machine-readable—essentially a piece of code transmitting invoice data from one system to another. Most software solutions allow you to convert e-invoices into PDFs for easier human readability, but the actual transmission happens with e-invoices, not through the PDF itself.

This automation streamlines the entire invoicing process: invoices are automatically generated, validated, issued, received, re-validated, archived in both systems, and in many cases, paid instantly—eliminating manual work and reducing errors.

 

 

Get The Most Out Of Invoicing

Streamlining your invoicing is a great step, but SaaS platforms, Neobanks, B2B software programs, and other service providers can take it even further. As mentioned before, integrating e-invoicing for your own business can be a lengthy, and expensive process—one that many companies simply choose to avoid.

That’s where you come in. By integrating the right invoicing API, you can offer invoicing as a service to your clients, making your platform more attractive and positioning it as a one-stop-shop solution. Since your clients already trust your platform, they are far more likely to use your invoicing feature rather than searching for an external solution—boosting loyalty and keeping them engaged.

Beyond that, you can turn invoicing into an additional revenue stream by choosing the right pricing model:

Usage-Based Pricing – Clients pay per invoice issued, allowing for scalable growth alongside their business. However, revenue remains unpredictable.

Subscription + Usage-Based Pricing – Clients pay a set monthly fee to unlock invoicing with some included benefits, while additional usage is charged separately. This model provides more revenue predictability while still offering flexibility.

Flat Subscription Model – Clients pay a fixed monthly fee for unlimited invoicing. This creates a stable, predictable revenue stream, though it carries the risk of clients not seeing enough value to commit long-term.

 

 

Choose The Right Invoicing API

There are thousands of invoicing APIs worldwide, but most are localized to a single country, new to the market (and therefore full of bugs and failures), or lack the necessary features to integrate seamlessly into your platform and upsell to your clients. That’s why choosing the right invoicing API is critical. Here are the most important features to look for:

Allow Multiple Users to Connect and Issue – If you want your clients to use the invoicing feature, the API must support multitenancy. This ensures that each client can issue invoices, brand them as their own, and keep data fully separate without accessing other users’ information.

Achieve an In-House Look – Clients trust your platform. If they see that invoicing is handled by a third-party provider, they might become sceptical—not only of the feature but of your platform as a whole. That’s why white-labelling is essential. The API should allow you to brand and colour the invoicing system your way, making it feel like a fully built-in solution.

Global Invoicing Compliance – Most invoicing APIs are localized, which may work if you operate in just one country with no plans for expansion. However, many businesses operate across multiple countries, requiring:

Strong Security Measures – Your API must protect your and your clients’ data. Invoices must be securely stored for long-term archiving, and regulatory compliance must be watertight. Look for an API with a proven security track record and industry experience.

Credible API with Market History – Many APIs appear overnight, but lack history, experience, and the ability to keep up with evolving regulations. Choose an API with:
