A small-business CRM rarely works alone. Sales teams also use email, accounting software, online stores, marketing tools, and phone systems. When those tools don’t talk to each other, staff copies data by hand, and records fall out of date. The right connections turn a simple pipeline into a working system.

This guide covers the top integrations for Bigin by Zoho CRM. It explains what each one does, who benefits, and where the limits sit. It draws on Zoho’s own help pages and community announcements, with independent sources for context. Recommendations are marked as such.

What Should You Know at a Glance?

Bigin calls its add-ons “toppings”. You find them in the Bigin Marketplace or under Settings.
Zoho builds several toppings itself, including links to Zoho Projects, Zoho Sign, and Zoho Campaigns, and partners build others.
Documented third-party connections include Google Workspace, QuickBooks Online, Shopify, Mailchimp, and Constant Contact.
Bigin’s page lists more than 100 cloud telephony vendors in its telephony marketplace, plus open APIs for custom connections.
QuickBooks works only with QuickBooks Online, and WhatsApp needs a workaround or partner extension in the sources reviewed.
Pricing changes over time, so confirm current plans on Zoho’s pricing page before you buy.

How Does Bigin by Zoho CRM Relate to Integrations?

Bigin by Zoho CRM is a pipeline-centric CRM built for small businesses. Zoho’s help documentation describes it that way, and the design explains why integrations matter so much. A pipeline CRM tracks deals through stages, but it relies on other tools for email, billing, marketing, and communication. Each connection brings data into the pipeline or sends it out.

This article follows directly: which integrations deliver the most value for a Bigin user, and how should you choose among them? Bigin’s integrations page groups connections into Zoho apps, third-party apps, telephony, and open APIs. The sections below follow similar logic, but add context on use cases, limits, and Setup.

Why Do Integrations Matter for a Small-Business CRM?

What Problems Do Integrations Solve?

Integrations remove duplicate work. Without them, a salesperson types a customer’s details into the CRM, then retypes them into an accounting tool and a mailing list. Each copy creates a chance for error. As a result, teams argue about which record is correct.

Integrations also add context. When a CRM shows order history or email campaign activity, a salesperson prepares better for each call. This is an expert observation about how connected data tends to help, not a vendor claim.

What Is a Topping?

A topping is Bigin’s term for an add-on that extends the CRM. Zoho’s P r ojects announcement shows the setup path: Settings, then Toppings, then Built by Bigin. Partner toppings appear in the Marketplace.

Some toppings carry an extra cost. Zoho’s Bigin 360 announcement states that Express and Premier users pay extra for certain toppings, while Bigin 360 includes some of them at no added cost. Check which toppings your plan includes.

How Else Can Bigin Connect to Other Software?

Bigin offers three other routes. First, Zoho Flow connects Bigin to a large catalog of cloud apps without code. A CRM Masters blog post puts the catalog at more than 1,000 apps, but treat that figure as a consultant’s claim and confirm it with Zoho. Second, Zapier offers similar automation. Third, Bigin’s open APIs let developers build custom connections.

Bigin’s integrations page also invites partners to publish extensions in the Marketplace. As a result, the list of available integrations keeps growing, so you should always check the current Marketplace.

Which Zoho Apps Integrate Best with Bigin?

How Does the Zoho CRM Integration Work?

Many companies outgrow Bigin and move to Zoho CRM, and Zoho offers a bridge. Bigin’s integrations page describes a connection that syncs modules such as Contacts and Companies. In contrast, Zoho’s Bigin for Zoho CRM help article describes an extension that makes one-way changes in Bigin from within Zoho CRM.

The help article adds that you can add contacts, accounts, and deals from Zoho CRM to Bigin, and that workflow rules can do this automatically. It also states that the extension is available in the US, EU, IN, AU, CA, and JP data centers. Confirm the sync direction and your data center before you plan around this connection.

How Does Zoho Campaigns Help with Email Marketing?

Zoho’s Campaigns integration post explains that you can sync Bigin contacts into Zoho Campaigns and send email campaigns to them. You can choose an immediate or periodic sync, and set criteria so only matching contacts transfer.

The sync also works in the other direction for engagement. Contacts who open and click campaigns appear in Bigin, and the campaigns show in the contact’s detail view. Opt-outs flow back too: the post states that opted-out contacts update as “Opt-out” in Bigin. This protects your team from emailing people who left your list.

How Does Zoho Projects Support Delivery Work?

The Zoho Projects integration suits service businesses that start work after a deal closes. According to the announcement, you can create a project from a closed deal’s record and assign team members to tasks. Administrators set up the integration and control which users can use it through profile settings.

The post also states that the Zoho Projects integration is available in all Bigin editions, including the Free plan. For example, a web agency could close a deal and create a project with design, development, and testing tasks in one flow. This connection needs a Zoho Projects portal, which you can create during Setup.

What Do Zoho Sign, SalesIQ, and Marketing Automation Add?

Zoho announced three further add-ons in a community post. Zoho Sign lets you send documents for signature from a Bigin record, and you install it from the Bigin Marketplace. Also, Zoho SalesIQ shows contextual Bigin data inside the SalesIQ chat window. The Marketing Automation connection requires you to map fields between the two systems in its integration settings.

Together, these three cover a common sequence: a website chat starts a conversation, the CRM holds the context, and a signed agreement closes the deal. Confirm plan and regional availability for each one before you rely on it.

Which Third-Party Integrations Do Bigin Users Choose Most?

Why Does the Google Workspace Integration Matter?

Google Workspace is the most common starting point for small teams. According to Bigin’s Google Workspace page, the integration syncs contact and calendar information between Bigin and Google Workspace. It can add your Google contacts to Bigin and bring other Google Workspace users into Bigin.

The page also describes calendar sync, which prevents a salesperson from managing two schedules, and a Gmail connection. The effect is practical: a team can keep working in Gmail and Calendar while Bigin captures the customer record. Review which contacts you import, because a full import can pull in personal or irrelevant contacts.

What About Microsoft 365?

A CRM Masters blog post lists a Microsoft 365 integration that covers Outlook, OneDrive, and Teams. That source is a consultancy blog, not Zoho documentation, so verify the exact scope in Zoho’s help center before you promise it to a team. A Zoho community thread also shows users hitting issues connecting business calendars to Bigin, which reinforces the advice to test before rollout.

If your company runs on Microsoft tools, run a short test with two users. Check email logging, calendar sync, and file access separately.

How Does the QuickBooks Integration Connect Sales and Accounting?

Zoho’s QuickBooks announcement states that customer data, invoices, expenses, and estimates synchronize between Bigin and QuickBooks. It also states that the integration works only with QuickBooks Online. You install it from Setup, then Topping, then QuickBooks, and you configure module sync.

The announcement lists two benefits: it removes duplicate data entry, and it lets you view outstanding payments and estimates in Bigin. A salesperson can then check whether a customer paid before they pitch an upsell. If you use QuickBooks Desktop, this topping does not apply, so ask Zoho about alternatives.

How Does the Shopify Integration Work for Online Stores?

Zoho’s Shopify topping announcement describes a two-way sync of contacts, products, and orders. After Setup, Bigin creates a “Shopify E-commerce Pipeline,” so you can manage orders in Bigin’s pipeline view. Opening a Shopify customer’s record also shows previous order history.

Setup requires your Shopify shop name, shop URL, and an access token, which you create by building an app in Shopify. A store owner can then spot repeat buyers and plan follow-ups. Allow time for the token setup, because it takes more steps than a one-click install.

Which Email Marketing Tools Connect Beyond Zoho Campaigns?

Bigin’s integrations page lists a Constant Contact integration, and the CRM Masters post lists Mailchimp. A Mailchimp connection syncs Bigin contacts into mailing lists for targeted campaigns, according to that post. Choose the tool your marketing team already uses, because switching email platforms costs more than any integration saves.

Zoho also published partner toppings for email validation built by Upwise Professionals. According to the announcement, they validate email addresses automatically and can verify up to 100 addresses with one click. Clean addresses reduce bounces, which protects your sender reputation.

How Can You Add Telephony and Messaging to Bigin?

Which Telephony Options Does Bigin Support?

Bigin’s integrations page states that, besides its built-in telephony, customers can connect to more than 100 cloud-based telephony vendors from the telephony marketplace, without hardware. A sales team that calls many prospects benefits most. Calls are logged against contact records, so managers can see who spoke to whom.

Before you choose a vendor, check coverage in your country and the features you need, such as call recording. Vendor availability and pricing vary, so compare quotes.

How Do You Connect WhatsApp?

WhatsApp is a common request. A Zoho community post from 2025 says Zoho was building a native integration and offered two workarounds. The first uses Twilio or MessageBird extensions from the Bigin Marketplace, built by the partner Ulgebra, which record WhatsApp messages as notes on contacts or deals. The second uses Zapier or Zoho Flow to connect Bigin with Woztell.

That post is several years old, so check whether Bigin now offers a native option. A CRM Masters blog post lists WhatsApp automation for reminders and follow-ups, but it does not replace Zoho’s own documentation. Verify messaging costs and WhatsApp’s business terms separately.

How Do Zoho Flow, Zapier, and APIs Fill the Gaps?

When Should You Use an Automation Platform?

Use Zoho Flow or Zapier when no native integration exists for your tool. A flow connects a trigger, such as a new Bigin contact, to an action in another app, such as adding a row to a spreadsheet. Simple flows require no coding.

For example, an illustrative consultancy could trigger a flow when a deal reaches the “Proposal Sent” stage. The flow could create a follow-up task and notify a manager in a chat tool. Keep flows simple at first, and document each one so colleagues can maintain it.

When Do Open APIs Make Sense?

Bigin’s integrations page states that you can connect Bigin to any third-party application through its APIs. APIs suit companies with developers or an implementation partner. They also suit special cases, such as syncing a custom internal tool.

On the other hand, custom builds need maintenance. If Bigin or the other system changes, the integration may break. So, prefer native connectors and automation platforms before commissioning custom code.

Which Integrations Should You Prioritize?

How Do the Top Integrations Compare?

The table below summarizes the integrations covered above. It reflects the sources cited, and you should confirm details in Zoho’s current documentation.

Integration	Best for	Key function	Watch out for
Google Workspace	Teams using Gmail and Calendar	Contact and calendar sync	Review imported contacts
Microsoft 365	Teams using Outlook and Teams	Email, files, calendar (per a consultancy post)	Verify scope in Zoho docs
QuickBooks Online	Sales and accounting alignment	Syncs customers, invoices, expenses, estimates	Works only with QuickBooks Online
Zoho Campaigns	Email marketing	Contact sync, opt-out updates	Needs a Campaigns account
Zoho Projects	Service delivery	Create projects from deals	Needs a Projects portal
Shopify	Online stores	Syncs contacts, products, orders	Token setup required
Zoho Sign	Contracts	Send documents for signature	Confirm plan availability
Telephony vendors	Call-heavy sales	Call logging	Check regional coverage
WhatsApp	Messaging	Notes on contact records	Workarounds in sources reviewed

How Do You Match Integrations to Your Business Type?

Start with your main workflow. Service businesses benefit most from Google Workspace or Microsoft 365, Zoho Projects, and Zoho Sign. Retailers benefit most from Shopify and an email tool. Teams that sell by phone benefit most from a telephony tool.

Do not install everything at once. Pick the one or two integrations that remove your most repeated manual task, then add others as needs appear. This approach keeps the system simple, which fits Bigin’s purpose.

What Criteria Should You Check Before Installing?

Use this checklist for each topping:

Data direction. Does data flow one way or both ways?
Plan fit. Does your Bigin edition include the topping, or does it cost extra?
Permissions. Who can set it up, and who can use it?
Data volume. Do record or sync limits apply?
Support. Does Zoho or a partner maintain it?
Regional availability. Does your data center support it?

What Do Integrations Cost and Which Plans Matter?

Zoho’s Bigin 360 announcement describes a higher edition with increased feature limits for items such as mass emails, custom fields, and automation rules. It also states that certain toppings come pre-installed at no extra cost in Bigin 360, including Booking Pages, Email-In, and File Cabinet. In contrast, Express and Premier users pay extra for those toppings.

Third-party price trackers list per-user monthly prices for Express, Premier, and Bigin 360, but Zoho can change prices and vary them by region. Check Zoho’s pricing page for current figures. Also ask whether the topping you want carries its own fee, and whether the third-party tool needs a paid plan, such as a Campaigns or Projects subscription.

What Limitations Should You Plan For?

Which Technical Limits Appear in the Documentation?

Several limits surface in the sources reviewed:

The QuickBooks topping supports QuickBooks Online only.
The Bigin for Zoho CRM extension runs in six listed data centers.
The Shopify topping needs an access token from a Shopify app.
The Zoho Projects topping needs a Zoho Projects portal, and administrators control user access.
The WhatsApp options rely on partner extensions or automation platforms.

Zoho’s documentation changes as the product grows, so a limit today may disappear later. Always confirm before you commit.

What Operational Risks Should Teams Consider?

The biggest risk is not technical. Teams install integrations without defining who owns them. When a sync fails, nobody notices for weeks. Assign an owner to each integration and review sync results monthly.

Data quality is the second risk. A sync spreads bad data as fast as good data. Clean duplicates and standardize fields before you connect systems. In addition, check privacy rules for customer data, especially when you move it between tools.

How Do You Set Up and Test an Integration?

Follow a short, repeatable process for each new connection.

Define the goal. State the manual task you want to remove.
Check plan and region. Confirm availability and cost.
Clean your data. Remove duplicates and align fields.
Install in a test setup. Use a few records, or a sandbox if available.
Map fields. Match each field and confirm the sync direction.
Run a pilot. Let two or three users work with it for a week.
Roll out and monitor. Train the team and review sync results regularly.

Document every integration in a shared list. Include the owner, the purpose, and the date of the last review. This habit helps when staff change roles.

What Is the Bottom Line on the Top Integrations for Bigin by Zoho CRM?

The top integrations for Bigin by Zoho CRM fall into four groups: Zoho apps such as Campaigns, Projects, and Sign; productivity suites such as Google Workspace; business tools such as QuickBooks Online and Shopify; and communication channels such as telephony and WhatsApp. Bigin by Zoho CRM works best when you connect the tools that remove your most repeated manual work, not every tool available.

Start small. Pick one or two integrations, confirm plan, region, and sync direction, and pilot them with a few users. Then expand as your process matures. If a native integration does not exist, try Zoho Flow, Zapier, or the open APIs before you consider custom development.

Frequently Asked Questions

Does Bigin integrate with QuickBooks?

Yes, with QuickBooks Online. Zoho says customer data, invoices, expenses, and estimates sync between the two systems. The top plan does not support other QuickBooks versions.

Can I use Zoho Projects with the Bigin Free plan?

According to Zoho’s announcement, the Zoho Projects integration is available in all Bigin editions, including the Free plan. You still need a Zoho Projects portal, and plan terms can change, so confirm current availability.

Does Bigin work with WhatsApp?

The sources reviewed describe workarounds: Twilio or MessageBird extensions from the Bigin Marketplace, or Zapier or Zoho Flow with Woztell. Zoho said in 2025 that it was building a native option. Check the Marketplace for the current status.

Can Bigin connect to apps that have no native integration?

Yes. Zoho Flow and Zapier connect Bigin to many cloud apps without code, and Bigin’s open APIs allow custom connections. APIs need developer skills and ongoing maintenance.

Do integrations cost extra?

Sometimes. Zoho says Express and Premier users pay extra for certain add-ons, while Bigin 360 includes some at no extra cost. Also check whether the connected tool needs its own paid plan.
