How to Connect Xero with Bigin by Zoho (With or Without an AI Agent)
Connect Xero payments and invoices to Bigin deals, optionally as an AI agent that keeps the pipeline in step with the books and pauses for a human before a payment reminder reaches a customer.
How do you connect Xero to Bigin by Zoho?
You connect Xero to Bigin by having Xero’s On New Payment Received trigger drive Bigin actions: the workflow pulls the payment with Get Payment, finds the matching account with Search Records, moves the deal with Update Deal, and logs the detail with Add Note, so a payment in the books becomes an updated deal in the pipeline. Bigin has no triggers of its own, so the workflow always starts from the Xero side. FlowRunner is a visual AI-agent orchestration platform where automations run autonomously and pause for human judgment on the steps that carry real consequence. The same connection can run as an AI agent that reads each payment and each aging invoice, keeps the pipeline current on its own, and pauses for a named human before Email Invoice puts a payment reminder in a customer’s inbox.
The problem it solves
Right now the bridge between your books and your pipeline is a person with two tabs open. A payment lands in Xero. Someone opens Bigin, hunts for the deal, drags it to the right stage, and types a note about what was paid. On a good week that happens same day. On a normal week it happens Friday, in a batch, from memory. Sales runs calls against a pipeline that says an account is still unpaid when the money cleared Tuesday, and the renewal conversation opens on the wrong foot.
The edges are worse than the happy path. A partial payment comes in and nobody adjusts the deal value. An invoice slides past due and the account owner finds out when the customer mentions it. A credit note gets issued in Xero and the deal in Bigin still shows the original amount. Chasing overdue balances turns into an awkward relay: finance flags it in a spreadsheet, sales is supposed to nudge the customer, and half the time the nudge never goes out or goes out twice. Nobody can say afterward who decided to send what.
How it works: the connection
The connection listens to Xero and writes to Bigin. Here is the plain version, grounded in the real connector actions.
- Trigger: Xero fires On New Payment Received when money lands against an invoice.
- Read: The workflow calls Get Payment and Get Invoice to pull the amount, the invoice number, and the contact behind it.
- Match the account: It calls Search Records in Bigin to find the contact and the open deal tied to that account. If the contact is new to the pipeline, it calls Create Contact so there is a record to work against.
- Update the pipeline: It calls Update Deal to move the deal to the stage your team uses for paid or partially paid work.
- Log the detail: It calls Add Note on the deal with the invoice number, amount, and payment date, so the history is on the record instead of in someone’s head.
- Assign the follow-up: When a balance remains, it calls Create Task in Bigin so the account owner has a dated to-do instead of a vague intention.
That is the “just connect them” answer. Payments become stage moves, balances become tasks, and the pipeline stops lying about the books. A second path runs the same way for aging: On Invoice Updated fires when an invoice status changes, and the workflow refreshes the deal and its notes so overdue accounts are visible where sales actually works.
Can an AI agent run it? (and why a human stays in the loop)
Yes, and this is where the connection stops being a sync and starts being a collections and pipeline assistant. Instead of a fixed script that always runs the same steps, an AI agent reads each event and picks the Xero and Bigin actions it needs as tools. Get Invoice, Get Aged Receivables, Search Records, Update Deal, Create Task, Email Invoice: these are the agent’s toolbox, and it chooses which to use based on what the payment or the aging report actually says.
The consequential step is the one that reaches a customer. Every morning the agent reviews the aging picture with Get Aged Receivables and Find Invoices, and for each overdue account it weighs the context: how long the relationship has run, whether a payment just arrived, whether a credit note is pending. When a reminder is warranted, it does not just fire Email Invoice. It drafts the ask and invokes a human-in-loop flow it holds as a callable tool. The workflow pauses and posts to your channel: “Invoice [number] for [account] is [days] overdue, balance [amount]. Approve sending the reminder?” The approver clicks once. Only then does Email Invoice go out, and the Bigin deal note records who approved it and when.
A ninety-day-old balance at a strategic account should not get the same treatment as a small invoice that slipped a week, and a threshold rule cannot tell them apart. The agent can, and when it is not sure, it stops and asks. Prospects call this the digital andon cord: like Toyota’s quality control pull cord, the workflow stops the line the moment it hits uncertainty, and your team pulls it back into motion with one click.
FlowRunner vs Zapier
Most teams connecting Xero to Bigin reach for Zapier first, and for good reason. Zapier’s connector library is enormous, its editor is quick to learn, and its template gallery includes ready-made Xero and Bigin combinations you can clone in an afternoon. For a one-way “new payment updates a deal” push, it is a fast, proven path.
The difference shows up when the workflow has to make judgment calls about customers and money. FlowRunner is built around native human-in-the-loop and AI-agent orchestration, where the agent decides when to pause for a person.
| What matters for this pair | FlowRunner | Zapier |
|---|---|---|
| Human-in-the-loop on customer-facing reminders | Native. The agent invokes an approval flow as a callable tool and pauses before Email Invoice | Available by adding approval steps, not a native agent decision |
| Who runs the flow | An AI agent reads the payment and aging data, reasons, and picks actions as tools | Predefined step sequence you configure per Zap |
| Users included | Unlimited users on every tier | Priced by task volume; seats vary by plan |
| Bring your own AI keys | Yes, BYOK | AI features tied to Zapier’s own AI offering |
| Self-hosted option | Yes, cloud-hosted or self-hosted | Cloud only |
| Pricing model | Transparent workflow-based tiers | Per-task pricing that gets harder to predict as volume grows |
If all you need is a stage move when a payment lands, Zapier will do it well. If you want the pipeline reconciled against the books and a named human on every message that reaches a customer about money, this pairing is the better fit.
Before and after
| Category | Before | After |
|---|---|---|
| Pipeline accuracy | Deals sit in the wrong stage until someone batch-updates Bigin from the Xero screen | Update Deal moves the deal the moment On New Payment Received fires |
| Payment visibility | Sales learns an invoice was paid when the customer mentions it | Add Note puts the invoice number, amount, and date on the deal within seconds |
| Overdue follow-up | Finance flags overdue accounts in a spreadsheet and hopes sales sends the nudge | The agent reviews Get Aged Receivables daily and queues reminders for approval |
| Reminder accountability | Nobody can say who approved chasing which account | Every Email Invoice send carries an approver’s name and timestamp in the audit trail |
| New account setup | Contacts exist in Xero but never make it into the pipeline | Create Contact adds them to Bigin the first time their money shows up |
What you can build
Payment to pipeline, hands off. On New Payment Received fires. The agent pulls the detail with Get Payment and Get Invoice, finds the account with Search Records, moves the deal with Update Deal, and logs it with Add Note. The pipeline reflects the books without anyone retyping anything.
Overdue reminder with named approval. The agent reviews Get Aged Receivables each morning, drafts a reminder for the accounts that warrant one, and invokes the human-in-loop tool. Email Invoice only fires after a person approves, and the deal note records the decision.
Credit note reconciliation. On Credit Note Created fires in Xero. The agent finds the affected deal with Search Records, adjusts it with Update Deal, and adds a note explaining the credit, so the pipeline value never overstates what the account is actually worth.
New customer intake. On Contact Created fires when finance sets up a new account in Xero. The agent calls Create Contact and Create Company in Bigin, then Create Task for the owner to qualify the relationship, so billing-first customers still enter the pipeline.
Renewal health brief. Before a renewal conversation, the agent pulls Get Aged Receivables and Find Payments for the account, then posts a payment-history note on the Bigin deal with Add Note, so the account owner walks in knowing exactly how the money side has behaved.
Common questions
Is it free to connect Xero and Bigin on FlowRunner? You can build and run the connection on a $100 credit with no credit card, which is roughly 67 days free on the Growth tier at $45/mo. Both connectors are available on every FlowRunner tier, and every tier includes unlimited users and unlimited workflows.
Can I self-host the Xero to Bigin workflow? Yes. FlowRunner offers a cloud-hosted option and a self-hosted option, so the connection can run inside your own environment.
Does the AI agent need my own OpenAI or Claude key? FlowRunner uses a bring-your-own-keys model, so you connect the AI provider key you already have. You are not locked to one model.
What happens when the agent is unsure whether a payment matches a deal? The agent stops and invokes a human-in-loop step instead of guessing. It posts the Xero contact, invoice number, amount, and the closest Bigin candidates it found with Search Records, then waits for a person to pick the right deal or reject the match before anything is updated.
Which Xero events can drive a Bigin action? Xero offers eight triggers, including On New Payment Received, On Invoice Created, On Invoice Updated, On Contact Created, and On Credit Note Created. On New Payment Received and On Invoice Updated are the two most teams start with for pipeline sync, since Bigin has no triggers of its own and the workflow starts from the Xero side.
Does every overdue reminder require human approval? You decide. The agent evaluates each overdue invoice in context and escalates the ones that carry weight, such as a long-standing account or a large balance. A reminder email is only sent after a named approver signs off, and that approval is captured in the audit trail.
