The 13 Best Accounting Package Integrations in 2026

Your accounting software is the financial foundation of your business, but it can't-and shouldn't-do everything alone. By connecting specialized apps for payments, payroll, e-commerce, and more, you eliminate manual data entry, reduce errors, and create a single source of truth for your company's performance. This guide introduces the best accounting package integrations available today, showing you how to build a connected, automated system that supports your business as it grows.

1. Shopify

As the dominant force in e-commerce, Shopify's integrations are essential for any online seller. Rather than manually inputting daily sales, refunds, and fees, this connection syncs transaction data directly into your accounting software. It automatically creates sales receipts or invoices, tracks taxes collected, and logs payment processing fees, making reconciliation a matter of minutes, not hours. Beyond sales, it can sync inventory levels and customer information, providing a clear link between your storefront performance and your financial statements.

• Pros:
  • Reduces manual data entry for sales, taxes, and fees, saving significant time.
  • Provides real-time visibility into revenue and profitability per product.
  • Automatically segregates sales tax liabilities for easier filing.
• Cons:
  • Some accounting platforms require a third-party connector app (like A2X or Bold), which adds a monthly fee.
  • Advanced inventory syncing between multiple sales channels and accounting software can become complex.
  • Mapping payouts, which group multiple orders, can be confusing without a dedicated connector app.
• Pricing:
  • Shopify's base plans start at 29 per month. The integration itself is often free through the platform's app store, but a robust connector app may cost an additional 20-$100+ per month depending on order volume.

Who it's best for: E-commerce businesses of any size that use Shopify as their primary online storefront.

2. Stripe

Stripe is a leading payment processor for online businesses, and its accounting integrations are built to handle the complexities of digital transactions. Connecting Stripe to your books automates the entire payment lifecycle. It records an invoice as paid the moment a transaction succeeds, logs the associated processing fees, and tracks refunds. This automation is most valuable during reconciliation, where it can match the grouped deposits (payouts) that hit your bank account back to the individual customer sales, a task that is notoriously difficult to do manually.

• Pros:
  • Automates the reconciliation of bank deposits by matching payouts to corresponding sales and fees.
  • Provides line-item detail for every transaction, fee, and refund without manual effort.
  • Supports multi-currency transactions, simplifying international sales accounting.
• Cons:
  • Chargebacks and disputes still often require manual intervention and journal entries.
  • Transaction fees can add up quickly, becoming a significant expense to track.
  • Native integrations sometimes lack the detail of a dedicated third-party connector for mapping complex payouts.
• Pricing:
  • Stripe charges a per-transaction fee (e.g., 2.9% + 30¢). The accounting integrations themselves are typically free.

Who it's best for: Any service business, SaaS company, or e-commerce store that accepts online payments via credit card or digital wallet.

3. Gusto

Payroll is more than just cutting checks; it involves tracking wages, benefits, and tax liabilities. Gusto simplifies this by not only managing a company's HR and payroll processes but also by syncing detailed summary journal entries directly into your accounting system. Each time you run payroll, the integration automatically posts the correct amounts to your wages expense, employer tax liability, and other relevant accounts. This removes the risk of manual miscalculations and ensures your financial reporting is always accurate and up-to-date with your largest expense.

• Pros:
  • Drastically reduces payroll accounting errors by automating journal entries.
  • Provides detailed categorization of payroll expenses, including wages, bonuses, and taxes.
  • Ensures your liability accounts for payroll taxes are always current.
• Cons:
  • The monthly per-employee cost can be high for companies with a large part-time or seasonal workforce.
  • Advanced job costing features may require a higher-priced plan or a separate integration.
  • Mapping custom chart of accounts fields during setup can require some accounting knowledge.
• Pricing:
  • Gusto's plans start at a base fee of around 40 per month plus an additional 6 per employee per month.

Who it's best for: Small-to-medium-sized businesses looking for a full-service payroll and HR solution that seamlessly connects to their books.

4. Salesforce

For sales-driven organizations, Salesforce is the central hub for all customer activity. Integrating it with your accounting package bridges the gap between your sales team and your finance team. When a deal is marked "Closed-Won" in Salesforce, the integration can automatically trigger the creation of a draft invoice in your accounting system. This ensures faster billing, reduces the chance of deals being missed, and gives leadership a unified view of the sales pipeline and its impact on revenue projections.

• Pros:
  • Creates a seamless workflow from sales lead to final payment, speeding up the cash cycle.
  • Eliminates duplicate data entry for customer information and sales orders.
  • Provides a holistic view of customer data, including sales history, contact information, and payment status.
• Cons:
  • The cost of both Salesforce licenses and the integration connector can be very high.
  • Implementation is often complex and may require a dedicated consultant to set up data mappings and workflows correctly.
  • Can be excessive for small businesses with straightforward sales processes.
• Pricing:
  • Salesforce itself is a premium product with costs varying widely. Integration often requires a paid third-party application or a high-tier Salesforce plan.

Who it's best for: Medium to large businesses with dedicated sales teams that need to connect complex sales workflows directly to their financial operations.

5. Trello, Asana, & Monday.com

Service-based businesses live and die by their projects. Integrating project management tools like Asana, Trello, or Monday.com with accounting software converts project tasks and milestones directly into billable invoices. When a project stage is completed or tasks are marked as finished, the integration can add line items to a draft invoice automatically. This is especially powerful when combined with time-tracking features, ensuring every billable minute spent on a project is accurately captured and invoiced, preventing revenue leakage.

• Pros:
  • Ensures that completed project work is billed promptly and accurately.
  • Improves project profitability analysis by linking real-time project costs to final invoices.
  • Saves project managers from having to manually compile billing information for the finance team.
• Cons:
  • Many native integrations have limited functionality, often requiring a workflow automator like Zapier or Make to create powerful connections.
  • Can be difficult to customize for non-standard billing arrangements (e.g., retainers with overages).
  • Effective use depends on disciplined project updates from the entire team.
• Pricing:
  • The PM tools themselves offer free and paid plans (typically 10-25 per user/month). Integration connections may come with an additional cost through automation platforms.

Who it's best for: Agencies, consulting firms, and service providers that need to connect project delivery directly to client billing.

6. Avalara

Sales tax compliance is a huge burden for any business selling across multiple states. Avalara (and similar tools like TaxJar) removes this complexity by integrating directly into your invoicing or e-commerce checkout process. It uses the customer's shipping address to calculate the precise sales tax rate in real time, accounting for the thousands of different tax jurisdictions and rules. Furthermore, it tracks your economic nexus thresholds in each state and can automatically file and remit the taxes on your behalf, making it an indispensable tool for multi-state sellers.

• Pros:
  • Provides rooftop-accurate sales tax calculations for every transaction, eliminating compliance risk.
  • Monitors economic nexus thresholds and alerts you when you need to register in a new state.
  • Automates the process of filing returns and remitting payments to state authorities.
• Cons:
  • The subscription cost is an added overhead for businesses.
  • The initial setup requires careful configuration to ensure all product types and nexus states are correctly identified.
  • Some transactions, like those involving exemption certificates, may still need supervision.
• Pricing:
  • Pricing is typically based on transaction volume, but plans start at around $20 per month for basic services.

Who it's best for: E-commerce and SaaS businesses that sell to customers in multiple US states or internationally.

7. HubSpot

HubSpot is one of the most popular CRM platforms for small and medium-sized businesses, blending marketing, sales, and service tools. Its accounting integrations focus on creating a 360-degree view of the customer journey. When a contact becomes a customer in HubSpot, their information syncs automatically to your accounting software, ready for invoicing. This connection keeps records aligned, so both your sales team (working in HubSpot) and your finance team (working in your accounting package) have the same updated information on contacts, companies, and deal statuses.

• Pros:
  • Maintains data consistency between sales, marketing, and finance departments.
  • Faster invoicing process as soon as a deal closes in the CRM.
  • Many accounting platforms offer high-quality, native HubSpot integrations at no extra cost.
• Cons:
  • Deeper, bi-directional syncs that include invoice statuses or deal updates may require a premium connector.
  • Less feature-rich than enterprise-grade Salesforce integrations.
• Pricing:
  • HubSpot offers a free CRM with paid tiers for more advanced features. Most accounting integrations are free additions from the app marketplace.

Who it's best for: Businesses that use HubSpot as their core CRM and want to align their sales and finance data.

8. Expensify

Managing employee expenses can be a messy process of chasing down receipts and manual reimbursement calculations. Expensify digitizes and automates this entire workflow. Employees snap a photo of a receipt, and Expensify's OCR technology automatically extracts the key data. From there, managers can approve expenses, and the integration pushes the categorized, approved expenses directly into the accounting software as bills or expenses, ready to be reconciled. It removes manual data entry and provides clear visibility into employee spending.

• Pros:
  • SmartScan OCR technology nearly eliminates manual data entry from receipts.
  • Simplifies the approval workflow and automates reimbursements to employees.
  • Syncs expenses with correct chart of accounts categorizations (e.g., travel, meals, software).
• Cons:
  • Pricing is on a per-active-user basis, which can prove costly for larger teams.
  • Corporate card reconciliation is a feature generally reserved for more expensive plans.
  • The user interface is powerful but can be less intuitive for first-time users.
• Pricing:
  • Plans typically start around 5-10 per user per month.

Who it's best for: Companies whose employees frequently incur out-of-pocket expenses for travel, supplies, or other business needs.

9. WooCommerce & BigCommerce

While Shopify leads the hosted e-commerce space, WooCommerce (for WordPress) and BigCommerce are hugely popular alternatives. Like the Shopify integration, these connections are designed to sync sales orders, customer data, taxes, and shipping fees directly into your accounting platform. They replace the error-prone task of manually tallying daily sales and provide accurate financial reporting based on real-time store performance. WooCommerce, being open-source, often offers more customization flexibility through a variety of third-party plugins.

• Pros:
  • Automates the flow of key sales data from your online store to your general ledger.
  • Inventory levels can be synced between your store and accounting software for better accuracy.
  • Reduces the time required for bank reconciliation by matching batched payments to specific orders.
• Cons:
  • The quality and reliability of integrations, especially for WooCommerce, can vary widely between different plugins.
  • Setup can be more technically involved than on a hosted platform like Shopify.
  • You may still need a separate connector app to properly handle details like payment gateway fees.
• Pricing:
  • WooCommerce is a free plugin, but the integration extensions often come with an annual fee (50-200). BigCommerce app costs vary.

Who it's best for: Online retailers who have built their stores on the WooCommerce or BigCommerce platforms.

10. Cin7

For businesses that sell physical goods-retailers, wholesalers, and manufacturers-managing inventory is just as important as managing cash. Dedicated inventory management platforms like Cin7 (or the now-integrated QuickBooks Commerce) provide granular control over stock levels across multiple channels and locations. The integration with your accounting software ensures that your biggest asset-inventory-and your Cost of Goods Sold (COGS) are always accurate on your financial statements. It syncs purchase orders, sales orders, and stock adjustments so your balance sheet reflects the true value of your inventory.

• Pros:
  • Keeps the inventory asset value on your balance sheet perfectly in sync with physical stock counts.
  • Automatically calculates and posts Cost of Goods Sold entries for accurate profit margins.
  • Synchronizes sales and purchase order data, reducing manual entry.
• Cons:
  • These are advanced, often expensive systems with a steeper learning curve than basic accounting inventory modules.
  • Implementation and data migration can be a significant undertaking.
• Pricing:
  • Inventory management suites are a premium service, with plans often starting at 200-400 per month depending on features and SKU count.

Who it's best for: Product-based businesses that have outgrown the basic inventory features within their accounting software.

11. Harvest

For freelancers, agencies, and consultants, time is literally money. Time tracking apps like Harvest let you and your team log hours against specific clients and projects. Its powerful accounting integration then converts those billable hours directly into professional invoices within your accounting system. You can pull unbilled hours and expenses tracked in Harvest right onto an invoice, ensuring that you bill for every minute of your work without having to manually sift through timesheets.

• Pros:
  • Creates invoices directly from tracked time and expenses, preventing lost billable hours.
  • Syncs payments received in your accounting software back to Harvest, marking invoices as paid.
  • Offers project budgeting features that help you monitor profitability in real time.
• Cons:
  • Depends on consistent and accurate time-logging by all team members.
  • The direct integration might not cover every feature-some advanced workflows might need a tool like Zapier to connect.
• Pricing:
  • Harvest offers a free plan, with a paid Pro plan running about $12 per user per month.

Who it's best for: Service-based businesses that bill clients on an hourly or project basis and need a simple way to create accurate invoices from their timesheets.

12. Zoho Apps

Zoho offers an entire suite of business applications, including its own accounting package (Zoho Books), CRM, project management, and inventory tools. If your business is heavily invested in the Zoho ecosystem, its deep, native integrations are a significant advantage. Zoho apps are designed to work together, providing a near-seamless flow of information from a sales lead in Zoho CRM to a project in Zoho Projects, and finally to an invoice in Zoho Books. This creates a tightly woven system that can feel like a custom-built ERP without enterprise-level cost.

• Pros:
  • Extremely tight integration between apps developed by the same company.
  • Offers a unified experience and a central dashboard for managing multiple business functions.
  • Can be more affordable than buying best-of-breed solutions from multiple different vendors.
• Cons:
  • While the integration is great, individual modules may not be as feature-rich as an equivalent standalone product (e.g., Salesforce or QuickBooks).
  • Committing to one ecosystem can lead to vendor lock-in.
• Pricing:
  • Zoho pricing varies by app, with many offering free tiers. Zoho One, an all-inclusive bundle, costs around 30-45 per employee per month.

Who it's best for: Businesses looking for an all-in-one suite of applications where tight integration across all functions is the top priority.

13. Custom API Integrations

Sometimes, an off-the-shelf solution won't work. Businesses with unique operational software or complex, proprietary workflows can use an accounting platform's Application Programming Interface (API) to build their own custom integration. This gives a company complete control over what data is synced, how often it syncs, and how it is mapped between the two systems. Although it's the most powerful option, it's also the most resource-intensive, requiring skilled developers to build and maintain the connection.

• Pros:
  • Offers limitless flexibility to connect any software and automate any workflow.
  • Provides a tailored solution that fits a business's exact operational needs.
  • Ensures data integrity and security by building to your own specific standards.
• Cons:
  • Requires significant investment in development time and money.
  • Custom integrations must be maintained and updated whenever the connected software's API changes.
  • Places the full responsibility for troubleshooting and support on the in-house team.
• Pricing:
  • Highly variable, as it depends entirely on the scope and complexity of the project. Costs can range from a few thousand dollars to tens of thousands or more.

Who it's best for: Larger enterprises or niche businesses with a dedicated IT team and specific workflow requirements that cannot be met by pre-built integrations.

Final Thoughts

Choosing the right integrations can transform your accounting software from a simple record-keeping tool into the command center of your business. By automating data flow between the tools you use every day, you not only save time and reduce errors but also gain the clarity needed to make smarter business decisions.
