Duplicate leads in the CRM: where they come from and how to clean them up
Sado AI team · · 4 min read
In short
Duplicate leads appear in a CRM when one customer comes through several channels (a call, Instagram, a website form) or calls twice, and each contact opens a new lead. To clean them up, make the phone number in one format (+998 XX XXX XX XX) the key, check regularly with the CRM’s duplicate search and merge cards rather than delete them. To stop new ones, set a rule: a new contact from a customer with an open deal goes into that deal. Before a calling campaign, remove repeated numbers.
Where duplicate leads come from
For example, Dilshod asks for a price on Instagram in the morning, calls at lunchtime and fills in the website form in the evening. The CRM now has three leads and three managers in charge. The usual causes:
- One person writes or calls through several channels, and each channel creates its own lead.
- The customer couldn’t get through the first time and called again: another lead.
- The number is written differently: +998 90 123 45 67, 901234567, 998901234567. To the CRM those are three numbers.
- A manager creates a lead by hand without searching the number first.
- A list imported from Excel overlaps with old contacts in the CRM.
The harm is clear too: two managers call the same customer, the customer gets annoyed, the second manager can’t see the first conversation, and the report shows many leads and a low sales rate.
How to clean up existing duplicates
- Pick one key: the phone number. Bring all numbers to one format: +998 XX XXX XX XX.
- Run the CRM’s own duplicate search: both Bitrix24 and amoCRM have one. Search by number first, then by name.
- Merge cards, don’t delete them. The second lead may hold a call recording, a note or a task; merging keeps the history in one card.
- Which card stays: usually the oldest or the most complete. Its manager stays in charge.
- One number, two people (a husband and wife, a shared office line)? Don’t merge: make two contacts and leave a note.
- Check regularly, for example once a week. A year of duplicates can’t be cleaned in a day.
How to stop new duplicates
Agree one table with your managers on what to do in each case:
| Situation | What we do |
|---|---|
| A customer with an open deal calls again | No new lead; the call goes into that deal |
| The deal is closed and the customer returns a year later | A new deal, but on the old contact |
| The same day via Instagram and a call | One lead, both sources in the note |
| One number, two different people | Two contacts, a “shared number” note |
Ask for the number on your website form with a fixed mask (+998 and nine digits). And have managers search the number before creating a lead; it takes five seconds.
Before a calling campaign
If a number is on the list twice, the customer may be called twice. So remove repeats before you upload the Excel file to the portal’s Auto-calls section. The portal accepts numbers written in different ways and shows how many were accepted after the upload. How to prepare the list: calling a list from Excel.
A number that said “don’t call me” isn’t called again, however many times it appears on the list. More: AI outbound calls.
An AI operator makes clean-up easier
Sado keeps the number, recording, full transcript and a short summary of every call. A manager merging two leads can read both conversations and quickly see which card is more complete.
The Bitrix24 integration is ready, and our team connects amoCRM with you. When connecting, we agree which pipeline and stage new leads land in and who owns them. Merging contacts itself stays a CRM tool and a manager’s job. How calls land in the CRM: CRM and calls.
Questions
Can I just delete a duplicate lead?
Better to merge it. The second lead may hold a call recording, a note or a task, and deleting it loses them.
How often should we check for duplicates?
Weekly if you get many leads, monthly if few. And always before a calling campaign.
What if two people share one number?
Don’t merge them. Make two separate contacts with a “shared number” note, so a manager calling knows whom to ask for.
