TL;DRThe cost of a SaaS accounting solution varies significantly, with off-the-shelf options typically ranging from $30 to $300 per month, while custom builds can cost $15,000 to $60,000+ upfront. Building a custom solution is ideal for businesses with unique workflows, complex integration needs, or specific reporting requirements, whereas buying an off-the-shelf solution is better for SMBs needing quick setup, budget constraints, or standard accounting processes.

A SaaS accounting solution can either be a custom-built platform tailored to your unique financial workflows or an off-the-shelf software package you subscribe to. The best choice depends on your business size, complexity, and specific needs.

What are the costs of a SaaS accounting solution?

The cost of a SaaS accounting solution varies wildly. Off-the-shelf options typically range from $30 to $300 per month for basic plans, with advanced features or more users pushing the price higher. For example, a small business might pay $50/month for QuickBooks Online's Plus plan, while a larger company needing payroll and advanced reporting could spend $200/month or more.

Custom SaaS accounting solutions, on the other hand, involve a significant upfront investment. A full build can range from $15,000 to $60,000+, depending on the complexity of features like automated invoicing, multi-currency support, custom reporting, and integration with other business systems. This price includes the design, development, testing, and initial deployment of your software. Ongoing costs for custom solutions are typically lower than subscriptions, mainly covering maintenance, hosting, and occasional updates.

When should you build a custom SaaS accounting solution?

Building a custom SaaS accounting solution makes sense when off-the-shelf software doesn't fit your business. This is common for companies with:

A Discovery Sprint, which costs $2,500–$5,000, is the first step to determine if a custom build is the right path. It clarifies your exact needs and outlines the scope of a custom solution.

What features should a SaaS accounting solution have?

For businesses needing more, custom solutions can add advanced features like automated tax calculations, multi-entity consolidation, advanced job costing, or bespoke dashboards that pull data from various sources. This is part of everything Steve builds, ensuring your financial tools work perfectly together.

How do you implement a SaaS accounting solution?

Implementation varies based on your choice. Off-the-shelf solutions usually involve signing up, configuring basic settings, and migrating your data. This can take anywhere from a few hours to a few weeks, depending on the volume and complexity of your historical financial data.

Implementing a custom SaaS accounting solution is a more involved process. It starts with the Discovery Sprint to define requirements, followed by design, development, rigorous testing, and deployment. This typically takes several months. Post-launch, user training and ongoing support are critical for successful adoption. We also ensure your new system is supported by effective marketing, whether through Google Search ads to find new clients or SEO to improve organic visibility.

Choosing the right SaaS accounting solution is a strategic decision. For many businesses, an off-the-shelf product is sufficient.
