The client

The situation before De Marketing

An accounting firm with 12 years in the Nuevo Leon market. A 3-person sales team operating without a CRM — follow-ups via WhatsApp and memory. A business-card-style website with no conversion capability.

Leads were lost due to lack of follow-up — the team had no CRM

Spending $5k/month on Google Ads with no results tracking

Generic website that didn't differentiate the firm from competitors

Low close rate (15%) due to unstructured sales process

Key insight

The problem wasn't generating leads — they were already spending on Google Ads. The problem was that leads were falling through the cracks. Integrating a CRM with follow-up automation tripled the close rate without changing the team. The lesson: before investing more in acquisition, make sure your sales process has no leaks. In accounting firms, where contracts are recurring, every lead you close has extremely high LTV.

Is your firm losing leads due to lack of follow-up?

We integrate marketing + CRM so your team closes more without growing headcount.
