Before you start

Cédula de identidad — a visa alone is generally not enough
Proof of income or of the source of funds
Proof of a Guayaquil address, usually a utility bill
An Ecuadorian mobile number

Step-by-step

1
Get the cédula before attempting a full account
Ecuadorian banks work from the cédula. A visa in your passport is not the same thing, and applications without one are commonly refused without much explanation.

2
Choose between a bank and a cooperativa deliberately
The banks — Guayaquil, Bolivariano, Pacífico, Pichincha, Produbanco — have the branch networks and the better apps. The cooperativas de ahorro y crédito often pay noticeably better on savings and sit under a different regulator. Understand which supervisor stands behind your money before you choose.

3
Bring documentation of where your money comes from
Source-of-funds rules are applied strictly and a large inbound transfer without paperwork will be held. In a port city with a heavy trade-finance culture the scrutiny is if anything greater. Arrive with statements and a letter from the sending institution rather than answering questions retrospectively.

4
Understand the ISD before you move money out
The Impuesto a la Salida de Divisas is charged on funds leaving Ecuador, including outbound transfers and some card transactions abroad. The rate has been reduced repeatedly in recent years — confirm the current figure with the SRI rather than assuming, and factor it in before planning regular transfers home.

Set up transfers, payments and the municipal accounts
Interbank transfers, utility payments and mobile payment services work well. Note that your municipal property and business taxes are paid to the Alcaldía de Guayaquil on its own portal, separately from anything the SRI collects.

6
Keep small notes and expect coin change
Ecuador uses US notes and mints its own centavo coins alongside American ones. Breaking a fifty in an ordinary shop or a market is genuinely difficult. Withdraw in twenties and hoard small notes — it is a real daily habit here, and in a city where you would rather not be counting cash in the street it matters more than it sounds.

Things most newcomers don’t know

Dollarisation removes an entire category of financial risk, and people undervalue it until they have lived without it.

There is no exchange rate to watch, no spread on your salary, no devaluation eroding savings, no parallel market and no need to hold a second currency. Compared with Argentina, Peru or Colombia the mental overhead of managing money simply disappears, and a price quoted to you in 2026 means the same thing in 2028.

The ISD is the tax nobody warns you about, and it is charged on money going out.

The Impuesto a la Salida de Divisas applies to funds transferred out of Ecuador and to certain foreign card transactions. For someone paying a foreign mortgage, supporting family abroad or repatriating savings it is a recurring cost that does not exist in most countries. The rate has been cut several times as policy has shifted, so check the SRI's current figure — but do not plan a cross-border money flow without knowing it exists.

Guayaquil's banks understand trade finance in a way the capital's do not.

This is where the export economy banks. Letters of credit, export documentary collections, foreign-currency-denominated trade lines and the paperwork that goes with shipping perishable goods are ordinary business for a Guayaquil branch manager. If you are setting up anything that touches import or export, the relationship you want is here rather than in Quito — and it is one of the few genuinely commercial advantages the city has over the capital.

Carrying cash is a security decision, not just a convenience one.

Card acceptance is good in the malls, the northern suburbs and Samborondón and much patchier in the markets, the centre and among tradespeople — so some cash is unavoidable. In Guayaquil the standard local practice is to withdraw inside a bank or a mall rather than at a street ATM, to split notes between pockets, and never to count money on the pavement. Express kidnapping and ATM-followings are the specific risks residents plan around.
