Managing customers doesn't usually fall apart overnight. More often, slight gaps in the process slowly become bigger problems. Incidents like missed follow-ups, billing confusion, and unhappy customers will lead to revenue loss. Many businesses don't realise what's going wrong until customers start slipping away.
Here are some of the most common mistakes businesses make when onboarding and managing customers.
Treating Customer Onboarding as a One-Time Task
Many businesses see onboarding as "done" once a customer is added and billed. But customers come in through different channels. Sales calls, website signups, trials, and in-app. Forcing all of them into a single onboarding process creates confusion and error.
You'll often hear:

"I thought this customer already existed."
"Why do we have three records for the same customer?"

Zoho Billing supports multiple onboarding sources, sales-driven, self-service, API based and bulk import, which makes it easy for businesses to onboard customers into the system naturally without breaking internal workflow. This ensures onboarding remains consistent as acquisition channels expand.
Letting Customer Data Unorganised
As businesses scale, customer relationships become more complex. Some customers represent multiple branches. Others belong to specific categories, such as resellers or premium clients. Without structure, it becomes difficult to track who owes what and which terms apply.
Teams start asking:

"Which invoice belongs to the parent company?"
"Are these customers eligible for the same pricing?"

Zoho Billing's Customer Hierarchy & Customer Groups features bring order to growing customer data. Hierarchies help manage parent-child relationships, while customer groups let you apply pricing, payment terms, etc., consistently across similar customers.
Handling Customer Requests Manually
Customers frequently request basic actions such as downloading invoices, checking subscription status, updating billing details, or resetting passwords. When all of this goes through your support team, response times slow down, and customers get frustrated.
Common complaints sound like:

"Can you resend my invoice? I emailed yesterday. Why haven't I heard back?"

The Customer Portal feature in Zoho Billing shifts control to customers. They can view invoices, manage subscriptions, download statements, make bulk payments, update details, and reactivate subscriptions. This reduces dependence on support while improving transparency and trust.
Losing Customers for No Real Reason
When the trial expires or the payment fails, businesses often take extreme action, either by cutting access immediately or letting the unpaid subscription linger indefinitely. Both approaches lead to churn or revenue leakage.
Sales teams often say:

"We meant to follow up, but it slipped through."

The Free Plan option in Zoho Billing acts as a safety net. Trial users or customers with failed payments can be automatically moved to a limited-access free plan instead of being cut off completely. This keeps customers engaged and creates opportunities to convert or recover them later.
Poor Handling of Payment Failure
Payment failures are inevitable, but many businesses treat them as a one-off issue. Without a proper retry or reminder strategy, customers unintentionally churn, even when they are willing to pay.
Customers often say:

"I didn't even realise the payment failed."

With Dunning Management, Zoho Billing automates reminders, retries failed payments, and escalates communication based on configurable rules. You can also set up a secondary payment method to increase the likelihood of successful collections before cancellation.
Not Knowing The Customers At Risk
Many businesses react only after the customer leaves. By then, it's already too late. Without visibility into churn signals, teams miss opportunities to step in early.
This leads to hindsight comments like:

"We didn't know they were struggling."

Zoho Billing provides Reports, Churn Reports, including Under Risk Report & Renewals report that highlight customers with failed payments, downgrades, or cancellations. These insights help businesses proactively reach out, resolve concerns and prevent churn.
Making It Hard for Customers to Return
Customers may cancel for valid reasons, such as budget cuts, seasonal slowdowns, or internal changes. When returning requires starting from scratch, many don't come back.
Customer hesitates:

"Do we have to set everything up again?"

With In-term Reactivation in Zoho Billing, customers can resume a cancelled subscription without changing billing cycles or creating new invoices. This makes reactivation simple, quick, and frictionless, especially when enabled directly through the customer portal.
Being Aware is the Key
Customer management challenges rarely stem from a lack of intent; they come from disconnected systems, manual processes and limited visibility. Zoho Billing addresses these gaps by bringing structure, automation and flexibility across onboarding, billing, lifecycle management and retention.
By avoiding these common mistakes and using the right tools at the right time, businesses can reduce churn, improve customer satisfaction, and build relationships that last longer than a single invoice.

Report on opportunities showing only the last note added.
Hi I need to create a report that shows the most recent note added to each opportunity. This is so management can see what the latest update is according to the assigned salesperson. One workaround is to use the status field but this implies added manual work and mistakes as the salesperson would have to copy the existing status to a note before adding the latest status... otherwise the activity history would be lost. My current workaround is a report on Notes with Opportunities as the related module.
