Sales and customer relationships covers capturing and closing leads in a CRM, running your email, phone and text channels, and automating the repeat work. It also covers handling complaints and keeping past customers coming back for repeat jobs and referrals.
This area covers what happens once someone reaches out. It starts with a CRM, so every lead lands in one place and moves through clear stages to a signed job and a paid invoice. Next come the email, phone and text channels you use to talk with customers, with consent records for marketing. Then automation takes over the repeat steps, with a person still checking anything risky. Last is customer service, where complaints are handled fairly and past customers are brought back for repeat work and referrals.
