Customer relationship management (CRM) is the practice of recording and organising every interaction with prospects and customers in one place. The term also names the software used for it. A CRM stores contacts, deal stages, notes, and next steps, so the history of a relationship survives when a person leaves.
In practice a CRM is a list of deals moving through stages: new lead, contacted, demo booked, offer sent, won or lost. Each deal carries a value, an owner, and a date. That structure answers questions a plain spreadsheet cannot: how many offers are open, which ones have gone quiet, and what you can expect to close this month.
A short example. You have 40 open deals worth 120,000 euros in total. Historically, 25 percent of deals at the offer stage close. If 16 of the 40 deals sit at offer stage and average 3,000 euros, the weighted expectation from that stage is 16 times 3,000 times 0.25, so 12,000 euros. Without recorded stages you would be guessing.
Founders often buy a CRM too early or fill it too late. With fewer than 20 contacts, a shared spreadsheet works. The moment two people touch the same customer, or you forget a follow-up, a CRM earns back its cost. The second mistake is treating it as a storage box. A CRM only helps if every deal has a next action with a date. Deals without one are the ones that get forgotten.
Do not confuse a CRM with an email marketing tool. Marketing tools send messages to many people at once. A CRM tracks individual relationships and what was promised. Some products do both, but the jobs differ. If your plan lists a CRM under operating tools, include the monthly cost per user and the hours needed to keep the data clean.
