What this is costing you today
Invoicing is a separate chore
You take payment at the till, then key the whole sale in again somewhere else to issue the invoice.
You don't know what's in the stockroom
You find out a product ran out when a customer is already asking for it.
Closing the till eats your evening
Balancing cash, cards and notes by hand at the end of the day — and it still doesn't add up.
Everything you need to sell formally
- Issue the FEL invoice on the same screen where you take payment
- Send the receipt to the customer's WhatsApp as the sale closes
- Deduct stock automatically, per location, with every sale
- Close the till with the cash-up and reports already calculated
- Run several locations from a single account
- Ask the AI assistant what sold and what's running out
Why FlowPOS rather than a notebook or a generic app
| Criterion | FlowPOS | Notebook | Generic app |
|---|---|---|---|
| FEL electronic invoicing | Included, issued through SAT-authorised certifiers | Issues no electronic document at all | Usually needs a separate system bolted on |
| Sending the receipt over WhatsApp | The customer gets their invoice on WhatsApp as the sale closes | Hands over a slip of paper written by hand | Typically prints or emails only |
| Inventory kept current | Deducted automatically with every sale, per location | Requires counting by hand to know what is left | Depends on the plan; often charged separately |
| Several tills in one location | Multiple simultaneous tills, each with its own close | One notebook per till, balanced by hand | Frequently limited to one till per location |
| Multiple locations | All in a single account, with consolidated reporting | One notebook per location, nothing consolidated | Usually one subscription charged per location |
| Billing in quetzales | Priced and billed in GTQ by a Guatemalan company | Not applicable | Many charge in dollars and invoice from abroad |
| Support in your hours | We reply on WhatsApp during your business hours | Not applicable | Email or chat, often in another time zone |
