Yes.
You need a simple CRM — but more importantly, a renewal calendar with bulk messaging.
Why
2,000 clientes is past the point where a spreadsheet can survive daily renewal cycles — you'll miss expirations and lose customers to whoever calls them first. But your situation isn't "manage leads through stages," it's "know whose plan expires today, send them an offer, log the response." That's a customer database plus a broadcast channel, not Salesforce. With daily renewals, the killer feature is filtering by "expiration date = today" and pushing an offer in under 5 minutes.
What you actually need
- Zoho Bigin (free for 1 user, ~$9/user/mo paid) — import all 2,000 clientes with a "Renewal Date" custom field and a "Current Plan" field. Filter view: renewals in the next 7 days. That single view is the whole job.
- WhatsApp Business API via Respond.io or 360dialog (starts ~$30–50/mo) — send the daily renewal offer as a template message to today's expiring clientes in one batch, not one chat at a time.
- A habit — the 9am renewal run — every morning, open Bigin's "expiring this week" filter, send the WhatsApp offer template to today's list, mark "Offered" on each. Twenty minutes, done.
Do this today
Export your 2,000 clientes to a CSV with columns Name, Phone, Current Plan, Renewal Date, Last Offer Sent. Sign up at bigin.com, click Import → upload CSV → map "Renewal Date" to a date field. Then create a saved filter "Renewals next 7 days." By tomorrow morning you'll see exactly which clientes to call before they churn.
What to ignore
Skip HubSpot Marketing Hub, Salesforce, and anything with the word "Suite" in it — at 2,000 contacts and daily offers, HubSpot's contact-tier pricing jumps fast and you'll pay for 90% of features you'll never touch. Ignore anyone pitching you a "telecom CRM" platform with a custom demo — those are built for carriers with 200,000+ subscribers, not a small reseller.
What doing nothing costs you
If even 5% of your 2,000 clientes churn each cycle because nobody contacted them in time, that's 100 customers lost — at any recurring telecom ticket, that compounds into the single biggest leak in your business within a year.
When to revisit this
When you cross 5,000 clientes or hire someone whose only job is renewals — then you'll want proper segmentation and automated WhatsApp sequences, not manual daily sends.
