Three things costing you time and money today

You get paid, but nothing formal is recorded

Loose receipts, bank transfers with no backing document, and corporate clients who need an invoice you can't issue.

Formalise the payment without changing how you work

FlowPOS issues the FEL electronic invoice at the moment of payment, through SAT-authorised certifiers.

  • Invoice the individual client or the company that sent them
  • Credit notes and voids from the same system
  • The document goes out over WhatsApp immediately
Ask how I invoice my services

You decide without knowing which service pays best

You know what came in today, but not which service generated it, who delivered it, or what it cost to deliver.

Reporting by service, by team member and by location

Every payment is classified as it is taken, so the report builds itself.

  • Which services sold most, and which carried the best margin
  • What each team member produced over the period
  • Location-by-location comparison, without consolidating by hand

A client's history lives in three places

The appointment in one notebook, the payment in another, and what was actually done last time in someone's memory.

One record per client

Every visit, service, payment and invoice attaches to the same client.

  • Look up what was done and when, without asking anyone
  • Identify your regulars and what they are worth
  • Win back the client who hasn't been in for months
