Friction
IVU gets charged to a Florida customer out of habit.
Fix
Ask your CPA which tax applies for each customer destination and note it on the invoice yourself. 4invoices does not decide tax by destination.
Sales to the mainland US
Selling from Puerto Rico to customers in the states involves no currency exchange or ordinary customs, but each state has its own sales tax rules and IVU does not travel with the goods. Splitting sales by destination and documenting each one prevents charging the wrong tax or missing one that was owed.
A market without a border, but with many jurisdictions
Puerto Rico is part of the US customs territory and uses the dollar, so shipping goods to a customer in Georgia involves no ordinary customs and no currency change. What does change is the tax jurisdiction: each state’s sales tax, and sometimes those of counties and cities, is set by that jurisdiction with its own rates and exemptions.
IVU is a Puerto Rico tax and does not replace the destination’s tax. An Island merchant selling online to customers in several states must ask, for each state, whether it has to collect that state’s tax, how much it sells there and which records are required. The answer changes from state to state and is updated often.
Since the US Supreme Court’s 2018 Wayfair decision, many states require remote sellers to collect their tax once they pass certain sales or transaction thresholds. The thresholds vary by state; your CPA or a state tax advisor should confirm them.
How to organize sales by destination
The condition for answering any question about state taxes is having each sale tagged with its destination: state and, if needed, county or city. That tag is created at the moment of invoicing. Reconstructing it afterward is much harder.
In 4softcrm you record each client’s domicile; on each 4invoices document you write the destination state. With that habit, at quarter end you can give your CPA a list of sales by state. The system does not calculate any state’s tax or produce ready-to-file state reports.
An example: a shop in Caguas sells handicrafts through its website. In one year it bills $120,000, of which $70,000 to customers in Florida, $22,000 in New York and the rest spread over twelve states. With the breakdown in hand, its CPA sees in which states it is approaching a threshold and can plan the registration in time.
Review the state breakdown every quarter, not once a year. A quarterly look shows which states are growing and lets your CPA warn you before a threshold is crossed, rather than telling you afterward that you should have registered months earlier.
Business customers and certificates
Sales to other businesses may be exempt from state tax when the buyer resells the goods or uses them in exempt activities. To support that exemption, the seller keeps a certificate issued by the buyer, in the form the relevant state accepts. Without a certificate, the seller can end up paying the tax out of its own pocket.
Ask for the certificate before the first exempt sale, check that it is complete and current and file it with that customer’s invoices. If the customer buys for years, set an annual review date. An expired or illegible certificate is worth little in a state audit.
Marketplaces and online platforms have their own rules: in several states, the platform is the one that collects the tax. When you sell through a marketplace, confirm what part of the collection it performs and what part remains yours.
Agree with business customers, in the supply terms, that they will send a new certificate whenever their details change and that you may charge the tax if the certificate turns out to be invalid. A clause like that turns a later argument into a documented rule.
Shipping, freight and logistics costs
Sea transport between the Island and the states is subject to US cabotage rules, which usually means higher freight than a seller in Georgia pays. Work out logistics cost when setting prices, and decide whether to charge it separately or include it. How freight is treated in sales tax varies by state.
Small sales travel by parcel carriers and postal services; larger ones by ocean or air carriers. Keep the shipping documents: they are the proof that the goods left for the destination you declare. A customer who says they received the goods in another state can change how the tax is treated.
Returns, exchanges and distant customers’ claims
Selling at a distance means returns at a distance. Set a written policy: who pays return freight, within how many days a return is accepted and how it is refunded. If you collected the destination state’s sales tax, the return requires refunding that too, and the adjustment is reflected in that state’s filing, not in IVU.
Issue a credit note for each return, citing the original invoice, and save the photos or evidence of the condition in which the product arrived. An example: a customer in Ohio returns a $300 part damaged in transit. With the shipping label, the photos and the credit note on file, the claim against the carrier and the correction with the state are two orderly steps, not an argument.
For repeat customers, a signed supply contract with delivery, return and payment terms avoids negotiating each order, and fixes from the start which law applies if a claim arises. 4mycontracts keeps the signed version and its amendments.
What the ecosystem does here, and where it stops
The products do not calculate state sales taxes, do not file returns in any state and do not connect to their authorities. Their contribution is documentary: PDF invoices with the data you write, a CRM with each customer’s domicile and signed contracts. With that base, your CPA or state advisor does the calculations and filings.
Before opening the sales channel to the states, meet with your CPA and ask three questions: in which states will I sell, at what volume must I register and what data do you need from me on each invoice. The answers become your list of mandatory fields.

Friction
No visibility on how much is sold per state.
Fix
Record each client’s state in your CRM and pull the per-state figures with your CPA. The products have no ready-made sales-by-state reports.
03
Friction
A business customer says it is exempt and nobody saved its certificate.
Fix
Request the customer’s exemption or resale certificate before you stop charging tax and file it with that customer’s invoices.
Do I have to charge IVU when I sell to a customer in another state?
IVU is a Puerto Rico tax and how it applies to sales shipped outside the Island depends on the kind of transaction and the rules in force. Do not charge it or skip it out of habit: ask your CPA to determine the treatment by type of sale and destination, and reflect it clearly on the invoice.
Must I register to collect sales tax in other states?
It depends on the state and on your sales level there. Many states set thresholds of sales or number of transactions above which a remote seller must register and collect. The thresholds change, so consult your CPA or a state tax advisor before your sales approach those values, and track your monthly sales per state.
Does 4invoices calculate each state’s sales tax?
No. 4invoices issues PDF invoices with the amounts you or your CPA define and archives them by customer. It does not look up state rates, determine the tax by destination or send it to any authority. For sales to several states you will need a rate source and a calculation process outside the ecosystem, which your CPA or e-commerce platform must provide.
What should I ask a business customer who says it is exempt?
Its exemption or resale certificate, in the form the destination state accepts, complete and current. File it with that customer’s invoices and review it every year. Without that document, a state authority can demand the uncollected tax from you, with surcharges, even if the customer stated verbally that it was exempt.
Invoices for US clients
PDF and CRM; the destination tax is set by your CPA.
