QuickBooks Online (QBO) has always been about giving businesses more control over their numbers, and this has covered everything from tracking sales to managing invoices. It helps people stay organized without needing to be accounting experts. But until now, there was one area where users felt limited: custom fields.
That’s changing. Intuit has opened up the Custom Fields API, but only to its Platinum Partners. And since G-Accon became a Platinum Partner in May, we’re among the very few who can bring this powerful new feature directly to you. We’ll explain what custom fields are, why they matter, and how they can save you time, and what makes G-Accon’s access unique.
What Are Custom Fields in QuickBooks Online (QBO)?
Custom fields are exactly what they sound like: extra fields you can add to your QBO forms and reports. These fields let you capture information that doesn’t normally appear in standard QuickBooks templates. Think about an invoice. Normally, it has basics like customer name, date, item, and total. But what if you also want to track:
- A project code
- A delivery date
- A client’s internal reference number
- A sales rep’s name
With custom fields, you can add those details. They appear on your invoices, sales forms, and even in your reports, giving you more flexibility. For accountants and bookkeepers, these fields are a game-changer. They allow firms to track details that matter to their clients without relying on workarounds or messy notes outside the system.
Why the Custom Fields API Matters
QuickBooks has allowed some custom fields for a while, but the new Custom Fields API takes things much further. An API (application programming interface) is what lets software connect and share information.
By using the API, apps like G-Accon can now:
- Sync custom fields directly into Google Sheets
- Automate reporting that includes those fields
- Consolidate data across multiple companies while keeping unique details intact
- Build templates that use client-specific information
Before, many firms had to manually add extra notes into spreadsheets or re-enter information that didn’t fit into QBO’s built-in categories. That meant wasted time, more errors, and less clarity. The API fixes that problem by making custom data part of the normal workflow.
Why It’s Exclusive to Platinum Partners
Here’s the big part: not everyone has this feature.
Intuit only gave access to the Custom Fields API to its Platinum Partners. That’s the highest tier in Intuit’s program, and there are only a handful of companies in that group.
G-Accon reached Platinum status in May 2025, and because of that, we can release the Custom Fields API to our QuickBooks Online customers right now.
What does that mean for you? It means that by working with G-Accon, you get tools and features that most other QBO users don’t. While others are still waiting, you can already take advantage of:
- More detailed reporting
- Less manual entry
- Stronger customization
- A competitive edge in how you use your data
How G-Accon Puts Custom Fields API to Work
At G-Accon, our mission has always been to connect QuickBooks with Google Sheets in a way that saves time and reduces errors. The Custom Fields API fits right into that mission.
Here’s what you can do now:
1. Smarter Reporting
Let’s say you manage multiple projects for a client. You can create a custom field for “Project Code” in QBO.
With G-Accon, that field syncs directly into Google Sheets. No extra typing, no messy copy-paste.
Your reports show exactly which project each invoice or payment belongs to.
2. Multi-Entity Consolidation
If you handle multiple companies, custom fields let you keep track of company-specific details while still consolidating your numbers. For example, one company might need a “Branch ID” field, while another might need “Sales Territory.” G-Accon can bring them all into one master report.
3. Custom Templates
Want to build a dashboard that includes custom data? With G-Accon’s integration, you can create templates in Google Sheets that pull in both standard QuickBooks numbers and your custom fields. That means your templates reflect the way you work, not just the way QuickBooks works.
4. Real-Time Sync
Custom fields update in real time just like the rest of your QuickBooks data.
Change something in QBO, and it flows into your connected Sheets instantly.
Why This Matters for Accountants and Firms
For firms, the benefits go beyond saving time. Custom fields make it easier to deliver insights that actually matter to clients. Imagine being able to say, “Here’s not just how much revenue you earned, but how much came from Project A versus Project B.” Or, “Here’s your profit margin by sales rep, not just by product.”
That’s the kind of detail that helps clients make better business decisions, and it’s the kind of insight that turns accountants into trusted advisors.
By using custom fields through G-Accon, firms can:
- Offer more valuable reports without extra manual work
- Reduce human error in data entry
- Tailor dashboards to client needs
- Free up staff time for higher-value advisory work
What Sets G-Accon Apart
Yes, other apps will eventually catch up. But right now, G-Accon is one of the only tools that can give you access to the Custom Fields API. That’s because of our Platinum Partner status.
This isn’t just a badge; it’s recognition that G-Accon is trusted by Intuit at the highest level. It also means we get early access to new features, direct support, and the ability to bring these benefits to you before most of the market.
So when you use G-Accon, you’re not just using a connector between QBO and Google Sheets. You’re using a partner with exclusive access and deep integration that others simply can’t match.
