If a POS vendor, a developer, or a new processor has asked you for a VAR sheet, you need two things: the document itself and the merchant account it points to. Here is what the sheet is, what it contains, who issues it, and what changes when your account moves.
What is a VAR sheet?
A VAR sheet — short for value-added reseller sheet — is the configuration document that connects your merchant account to the equipment and software that actually takes payments. It carries the credentials a payment gateway, POS system, or card terminal needs to route transactions to the right account at the right bank. You may also hear it called a parameter sheet or a tear sheet. Different name, same document.
If your merchant account is the destination, the VAR sheet is the set of directions.
What a VAR sheet contains
The exact fields depend on the acquiring platform, but the core of the document is consistent: your merchant identification details, the terminal or gateway identifiers assigned to your account, and the acquirer and bank routing information that tells the network where settled funds belong. Some platforms add their own required fields on top, so two VAR sheets from two processors will not look identical.
Every field matters. A VAR sheet is not a reference document you skim — it is configuration data that gets keyed into a terminal or gateway exactly as written.
When you need a VAR sheet
Three situations put a VAR sheet in front of you:
- A new terminal or POS system. The hardware has to be programmed with your account's credentials before it can process a single card.
- A gateway integration. Connecting an online gateway to your merchant account requires the same credentials in digital form.
- A new processor. When your merchant account moves, everything configured against the old account has to be reconfigured with a new sheet.
If none of those apply, you likely will not see a VAR sheet at all. Your processor handles it behind the scenes.
How to get a VAR sheet
Your processor or acquiring bank issues the VAR sheet, and it can only do so once your merchant account exists. The sequence is: apply, get approved, get boarded, receive the sheet. You do not fill a VAR sheet out yourself — you request it from the processor and pass it to whoever is configuring your terminal, POS, or gateway.
The practical question is how long the account itself takes, because the sheet cannot come first. The VAR sheet follows from the approved account. If a developer or POS vendor is waiting on it, tell your account contact up front so it is issued once boarding completes.
VAR sheets when you switch processors
This is where VAR sheets catch business owners off guard. The sheet is tied to a specific merchant account at a specific acquirer. If your previous processor exited and you have moved to a new one, the old sheet is dead weight — your terminals and gateway are still configured to route transactions to an account that no longer serves you.
The fix is straightforward but has to be done deliberately: open the new high-risk merchant account, request the new VAR sheet, and reconfigure each terminal and gateway integration against it before you retire the old setup. Plan the cutover for a slow day if you can, and confirm a live test transaction settles correctly before you consider the switch done.
If you are weighing the new provider at the same time, the terms should be on the table first. With us, every fee is disclosed in the merchant service agreement before you sign. You should know the terms of the new account before the new VAR sheet ever reaches a terminal.
Common VAR sheet problems and how to avoid them
Most VAR sheet trouble comes down to three avoidable mistakes:
- Mistyped fields. A single wrong character in a merchant or terminal identifier means declined or misrouted transactions. Have the person configuring the equipment work from the sheet directly, not from a copy typed into an email.
- An outdated sheet. Any change to your account can make the old sheet invalid. When your account changes, ask whether a new sheet is needed rather than assuming the old one still applies.
- Downtime during a cutover. Switching processors without the new VAR sheet in hand means days where nothing can be processed. Request the sheet the moment the new account is approved, and schedule the reconfiguration before you shut anything off.
Set up your account and your VAR sheet in one place
A VAR sheet is only as good as the merchant account behind it. If you need an account that stays open — and the configuration documents to put it to work — contact us. We will tell you exactly what your setup requires before you sign anything.
Frequently Asked Questions
VAR stands for value-added reseller. The sheet is the configuration document a payment gateway, POS system, or card terminal needs to route transactions to your merchant account at the right bank.
Yes. Parameter sheet and tear sheet are alternate names for the same document. Whatever your vendor calls it, it is the record that connects your equipment or gateway to your merchant account.
Your processor or acquiring bank issues it, and only after your merchant account is approved and boarded. You do not fill it out yourself — you request it from the processor and pass it to whoever is configuring your terminal, POS, or gateway.
No. A VAR sheet is tied to a specific merchant account at a specific acquirer. When your account moves, you need a new sheet from the new processor, and every terminal and gateway integration has to be reconfigured against it before you retire the old setup.
The merchant account comes first, because the sheet is issued against an approved, boarded account. Once you are approved, the VAR sheet follows when boarding completes. If a developer or POS vendor is waiting on it, tell your account contact at the start.
