Every record, entered once
The store on one side, invoicing on another, Mercado Libre off by itself. The same sale gets entered three times, and one of the three ends up wrong.
| Not connected | Connected | |
|---|---|---|
| The sale | Entered in the store, in the system and again for invoicing | Entered once |
| The invoice | Someone issues it separately | Issued from the sale itself |
| The payment | Matched to the sale by hand | Tied to its sale |
| Mercado Libre | One account at a time | Every account on one screen |
The idea is simple: every record is entered once and shows up everywhere.
Selling in Argentina?
If your company sells in Argentina from abroad, you will soon deal with Mercado Libre, Mercado Pago and ARCA (formerly AFIP) electronic invoicing. At Pulso (pulsosoftware.com) we are based in Córdoba, Argentina, and we connect your own system to all three.
ARCA invoices are issued in the name of your Argentine entity; what we build is the connection, so they come out of your system without anyone entering them again.
ARCA (formerly AFIP) electronic invoicing
Since October 2024, Argentina's tax agency AFIP has been called ARCA (Decree 953/2024).
We connect your system to ARCA electronic invoicing, so the invoice is issued from the sale itself and nobody has to enter it again on another screen.
At MyA Importaciones, the invoice goes out automatically when a sale closes.
Payments with Mercado Pago
We have integrated Mercado Pago purchases inside online stores since 2023; those were our first integration projects.
When the store is connected to your system, each payment stays tied to its sale and nobody has to match payments by hand. If you don't have a store yet, we build that too: see ecommerce and website development.
Mercado Libre: every account on one screen
Selling on Mercado Libre through several accounts means logging into each one to see how every company is doing.
For a company in that situation we built a report that brings them all together on one screen: income, profit and margin for each company, already calculated and kept separate from the others. It's in production, and you can see the screen further down this page.
Evolux, an agency that scales brands on Mercado Libre, is also a client: their website is featured on our ecommerce and website development page.
The AI assistant we built answers in the online store and hands the chat over to the salesperson's WhatsApp. The full case is on our AI automation page.
And whatever you already use
We connect the tools you already use, and whatever you need later on. Each integration is written into the quote before we touch anything: what it connects to and what it includes.

What people ask before we start
Are AFIP and ARCA the same thing?
Yes. Since October 2024, AFIP has been called ARCA, short for Agencia de Recaudación y Control Aduanero, Argentina's revenue and customs agency. Many people still search for it as AFIP: it is the same electronic invoicing.
Can my system issue invoices through ARCA automatically?
Yes. We connect the system to ARCA electronic invoicing so the invoice goes out without being entered separately. At MyA Importaciones, the invoice goes out automatically when a sale closes.
Can I see several Mercado Libre accounts together?
Yes. For a company that sells through several accounts, we built a screen where it sees all of them together, with income, profit and margin already calculated and each company kept separate.
Can you integrate Mercado Pago into my store or system?
Yes. We have integrated Mercado Pago purchases inside online stores since 2023.
Can you connect a system you didn't build?
Yes, we connect what you already use. First we look at what system it is and how it can be connected, and that goes into the written quote.
How much does it cost?
We don't have a list price, because no two systems are alike. First we look at your operation, then we send a written quote with what it includes and how long it takes, before we touch anything. The first conversation and the quote are free.
