Beyond Xero & Intuit: The Hidden APIs CPA Firms Should Be Mining (and Why It Matters)
3 MIN READ
Jessica Kentch, Founding Partner
In the race to modernize, most accounting firms are already familiar with pulling data from Xero or Intuit QuickBooks Online. And that’s a great start.
But if your API strategy stops there, you're leaving a mountain of insight—and efficiency—on the table.
Today’s leading firms are no longer thinking just in terms of financial reporting. They’re thinking in systems. That means pulling in data from multiple apps across the client stack—not just ledgers.
Let’s explore some of the most valuable APIs outside of Xero and Intuit, why they matter, and how they unlock deeper advisory, automation, and client value.
First, Why Should CPA Firms Care About APIs?
An API (Application Programming Interface) is a digital bridge that lets you connect and pull data from cloud apps automatically. Instead of downloading reports manually or using CSV exports, APIs allow for live data feeds, automation, and custom analytics.
For modern CPA firms, this means:
⚡ Faster, more accurate reporting
📊 Real-time dashboards for clients
🧠 Deeper insights across operations, sales, and behavior
🔁 Automated workflows that reduce admin and error
💥 Competitive advantage through data-rich advisory
APIs You Should Be Paying Attention To
Here are key platforms CPA firms can (and should) be integrating—especially those serving clients in retail, eCommerce, SaaS, or services:
🧩 1. Karbon (Practice Management)
Why it matters:
Karbon holds a goldmine of operational data—deadlines, task status, client communication, email metadata, and staff workload. By tapping its API, firms can:
Track real-time WIP and bottlenecks
Analyze team capacity and turnaround times
Create dashboards that connect productivity to profitability
Monitor SLAs and improve client experience
Use case: Create a live dashboard that shows overdue client deliverables by team or task type, pulled directly from Karbon.
🛒 2. Shopify (eCommerce)
Why it matters:
For retail clients, Shopify is the heartbeat of their business. The API lets you pull:
Sales trends
Returns and refunds
Average order value
High-performing SKUs
Seasonal patterns
Use case: Build a profitability dashboard that links Shopify sales with Xero COGS and Karbon advisory touchpoints—great for VC-backed clients.
🧾 3. Stripe (Payments)
Why it matters:
Stripe is the preferred gateway for startups and SaaS companies. Pulling in data from Stripe helps with:
Revenue recognition (ASC 606)
Churn analysis
MRR and ARR tracking
Failed payments and dunning workflows
Use case: Use Stripe’s API to identify at-risk accounts (based on failed payments or high churn) and push tasks to Karbon to intervene.
👩💻 4. HubSpot / Salesforce (CRM)
Why it matters:
Connecting CRM data allows firms to:
Correlate sales velocity with cash flow
Forecast based on pipeline
Track client acquisition cost (CAC)
Match marketing spend to financial outcomes
Use case: Build CAC vs. LTV dashboards by syncing HubSpot data with ledger-level billing in QBO or Xero.
📧 5. G Suite / Microsoft 365 (Email & Calendar APIs)
Why it matters:
These APIs help you:
Track client engagement (email opens, response times)
Measure internal meeting load
Automate reminders for deadlines and follow-ups
Build staff utilization models
Use case: Alert managers when key client communications haven’t been responded to in 48 hours—automated via Gmail API + Karbon integration.
🔎 6. Gusto / Rippling / Wagepoint (Payroll APIs)
Why it matters:
For clients with growing teams, payroll APIs offer insight into:
Headcount trends
Labor cost breakdowns
Department-level spend
Employee retention
Use case: Create a burn-rate dashboard that pulls payroll, bank balance, and invoicing data together to show runway in real time.
📦 7. Inventory Tools (e.g., DEAR, Cin7, TradeGecko)
Why it matters:
These tools connect finance with operations. You can extract:
Inventory turnover
Stockouts vs. overstock
SKU-level margins
Fulfillment timelines
Use case: Help retail clients forecast cash needs based on inventory cycles, not just sales.
Why This Matters: From Bookkeeping to Advisory Intelligence
When you expand your API ecosystem, you stop being a bookkeeper—and start becoming an intelligence layer for your client’s business.
It lets you answer questions like:
"Which products are driving profit, not just revenue?"
"Where are we losing margin due to refunds or churn?"
"How long before this client runs out of cash?"
"What clients are at risk of leaving based on communication trends?"
This is the level of service that earns premium fees, builds long-term relationships, and transforms your firm from a cost center to a strategic partner.
Final Thoughts: Build Your Data Stack, Not Just Your App List
Your client’s accounting software is just one piece of the puzzle. The real insights come when you connect the dots across platforms—and APIs are how you do that.
