The best accounting software for app integration
Starting price$38 per month
Free planFree trial
QuickBooks Online leads on US ecosystem depth, with 750 plus integrations covering payments, e-commerce, payroll, CRM, and reporting. Most US accountants know it, and most business apps build their QuickBooks connection first, which means Shopify, Stripe, PayPal, and Salesforce links tend to be mature and well supported. Simple Start starts at 38 dollars per month on recent list prices, with a free trial for evaluation.
The trade is seat math and tier gating. Users are capped by tier, from one on Simple Start to 25 on Advanced, and some integrations need higher plans. Intuit also raises prices regularly. For a US business whose stack must connect to the ledger without custom work, QuickBooks Online offers the deepest ready-made ecosystem.
What we like- 750 plus integrations
- Largest US accountant network
- Deep Shopify and Salesforce links
Watch out for- Per-seat pricing punishes growth
- Some integrations need higher tiers
- Prices rise often
#2Xero
Best for: Largest app marketplace4.4/5 on
G2 (1,832 reviews, checked Oct 2026)
Visit xero.com
Starting price$29 per month
Free planFree trial
Xero leads on marketplace size, with 1,000 plus apps covering payroll, point of sale, inventory, reporting, and industry tools. Unlimited users on every plan means the whole team and the accountant get in without seat math, and bank feeds are widely praised as faster and more reliable than rivals. Starter starts near 29 dollars per month on recent list prices, with a free trial.
The limits are caps and US gaps. Starter caps at 20 invoices and 5 bills per month, so steady businesses should treat the next tier as the real entry price, and US payroll runs through a Gusto integration rather than natively. Fewer US accountants know Xero than QuickBooks. For a growing team that wants the widest app choice without seat costs, Xero leads.
What we like- 1,000 plus marketplace apps
- Unlimited users
- Strong bank feeds
Watch out for- Starter caps invoices and bills
- US payroll runs through Gusto
- Fewer US accountants know it
#3Zoho Books
Best for: Zoho suite integration4.4/5 on
G2 (329 reviews, checked Oct 2026)
Visit zoho.com
Starting price$20 per month
Free planYes
Zoho Books suits teams already running Zoho apps, since it connects natively to Zoho CRM, Inventory, Projects, and Payroll beside a marketplace of 50 plus outside apps. A free plan covers businesses under 50,000 dollars in revenue, while paid plans start near 20 dollars per month, or 15 dollars on annual billing. Bank feeds and reconciliation run on all plans.
The trade is breadth. The outside marketplace is smaller than Xero or QuickBooks, so a niche app may need Zapier as a bridge, and advanced inventory sits on higher tiers. For a budget-conscious team building its stack inside Zoho, the native suite links beat a larger but looser marketplace.
What we like- Free plan under 50,000 dollars revenue
- Deep Zoho suite links
- 50 plus marketplace apps
Watch out for- Marketplace is smaller than Xero or QuickBooks
- Advanced inventory needs higher tiers
- Support varies by region
#4FreshBooks
Best for: Service billing integrations4.5/5 on

Starting price$23 per month
Free planFree trial
FreshBooks suits service businesses that bill by time or project and want their tools connected to invoicing. Its 100 plus integrations cover payments, time tracking, CRM, and project tools, while built-in time tracking and client payment links keep billing inside one flow. The Lite plan starts near 23 dollars per month on recent list prices, with a free trial.
The limits are caps and depth. Lite caps billable clients at five, inventory is absent, and accounting depth is lighter than QuickBooks or Xero for businesses with stock or complex books. For a freelancer or agency whose stack centers on billing clients well, FreshBooks integrates cleanly where it matters.
What we like- 100 plus app integrations
- Strong invoicing and time tracking
- Client payment links
Watch out for- Lite caps billable clients at five
- Inventory is absent
- Accounting depth is lighter than rivals
#5Wave
Best for: Free accounting with basics4.3/5 on
G2 (328 reviews, checked Oct 2026)
Visit waveapps.com
Starting priceFree
Free planYes
Wave suits micro-businesses that need free accounting with basic connections. Core accounting and invoicing cost nothing, PayPal links cover payments, and Zapier bridges to hundreds of other apps for teams willing to build simple automations. Setup takes minutes, and a Pro plan near 19 dollars per month adds automatic bank imports.
The trade is depth. Native integrations are limited next to QuickBooks or Xero, bank feed refreshes are limited on the free tier, and the product centers on single users rather than teams. For a solo operator who needs free books plus PayPal and Zapier, Wave covers the essentials.
What we like- Free core accounting
- PayPal and Zapier links
- Simple setup
Watch out for- Integrations are limited
- Bank refresh limits on free tier
- Single-user focus
Starting priceSee website
Free planFree trial
Sage suits mid-market teams that want a managed marketplace beside accounting that scales toward ERP. Its marketplace covers payroll, payments, CRM, and industry apps, with Sage Intacct as the step up for companies that outgrow small-business plans. A free trial covers evaluation before committing.
The limits are price clarity and weight. Pricing varies by product, bundle, and region, so the starting price here is written as See website, and setup needs more planning than QuickBooks or Xero. For a growing company that wants its accounting vendor to scale with it, Sage offers a managed path upward.
What we like- Managed app marketplace
- Payroll and payments links
- Scales toward ERP
Watch out for- Pricing varies by product and region, so check the pricing page
- Setup needs planning
- Small teams may find it heavy
#7Kashoo
Best for: Simple small-business links4.6/5 on
G2 (55 reviews, checked Oct 2026)
Visit kashoo.com
Starting priceSee website
Free planFree trial
Kashoo suits very small teams that want simple accounting with basic bank connections and no learning curve. Its interface stays plain, bank feeds pull transactions in, and a free trial covers evaluation. For a solo operator or tiny team that finds QuickBooks and Xero heavy, Kashoo keeps the ledger approachable.
The trade is ecosystem size. The integration list is small next to the leaders, reporting is basic, and pricing varies, so the starting price here is written as See website. For a business whose only must-have connections are a bank and a payment tool, Kashoo is enough, but growing teams will outgrow it.
What we like- Simple interface
- Bank connections
- Suits very small teams
Watch out for- Integration list is small
- Pricing varies, so check the pricing page
- Reporting is basic
#8FreeAgent
Best for: UK freelancer integrations4.3/5 on
G2 (45 reviews, checked Oct 2026)
Visit freeagent.com
Starting priceSee website
Free planFree trial
FreeAgent suits UK freelancers and small firms that want accounting with local tax features and clean bank connections. Bank feeds, PayPal and Stripe links, and UK-specific tax handling cover the daily routine for small service businesses, with a free trial for evaluation.
The limits are geography and ecosystem. Pricing varies by region, so the starting price here is written as See website, and the US app ecosystem is thin next to QuickBooks. For a UK freelancer or small firm that values local tax handling over a giant marketplace, FreeAgent fits well.
What we like- Bank feeds and payment links
- UK tax features
- Suits freelancers and small firms
Watch out for- Pricing varies by region, so check the pricing page
- US ecosystem is thin
- Payroll depth varies
How we chose
We ranked tools by integration count, connection quality, API access, bank feeds, ease of setup, and value at entry level pricing. We favored tools whose key connections sync both ways and stay maintained, since a marketplace logo for an abandoned integration helps nobody. We gave extra weight to bank feeds, payment links, and e-commerce connections, because those three integrations drive most daily automation for small businesses.
We also weighed entry cost honestly. Where published prices conflicted across sources, such as Xero Starter and FreshBooks Lite, we used the most recent commonly listed figures and noted that promotions change them. Where pricing varies by product and region, such as Sage, Kashoo, and FreeAgent, we wrote See website rather than guessing.
Buying guide
Start from the apps you already use. List your payment processor, store platform, CRM, payroll, and bank, then check each ledger for native connections to those five before looking at price. A native connection that syncs both ways beats a Zapier workaround that breaks silently, so test the exact sync you need during a trial rather than trusting a marketplace page.
Next, check tier gating. Some integrations need higher plans, and some caps, such as client limits or invoice caps, force an upgrade sooner than the headline price suggests. Import real data during a trial, run a full invoice-to-payment cycle through each connected app, and confirm that bank feeds refresh reliably for your bank.
Finally, plan for growth. A solo tool with a small marketplace may suit today but force a painful migration in two years, while a larger ecosystem costs more now and scales further. Pick the smallest ledger that connects cleanly to your must-have apps today, with a clear upgrade path for the apps you expect to add next year.
Frequently asked questions
What is the best accounting software for app integration overall?
Xero leads on marketplace size with 1,000 plus apps, while QuickBooks Online leads on US ecosystem depth with 750 plus integrations. The best pick follows which apps you already run.
Do I need native integrations or is Zapier enough?
Native integrations sync more reliably and usually handle two-way updates, while Zapier bridges gaps but can break silently and adds cost. Use native links for payments, stores, and payroll, and Zapier for edge cases.
How many apps do I really need connected?
Most small businesses need five: a bank feed, a payment processor, a store or CRM, payroll, and a reporting tool. Cover those five natively before chasing a large marketplace count.
Can I switch accounting software later without losing integrations?
Switching is possible but takes work: export data, rebuild connections, and re-test syncs. Picking a ledger with a clear upgrade path reduces the chance of a forced migration.
Does a free plan include integrations?
Sometimes. Zoho Books and Wave offer free plans with basic connections, while QuickBooks and Xero reserve full integration access for paid plans. Check integration limits on the free tier before relying on them.
